People who can do in-depth editing and research are not ordinary geological data managers, but usually professionals with geological professional technology and geological professional skills. In the geological data management team, some older professionals who used to be engaged in geological technology have transferred to museums to do geological data management. They are familiar with geological professional research and have profound professional technology accumulation. Because of their age, they can't adapt to the hardships of geological field work and turn to the post of data management. After a period of geological data management practice, they began to browse the relevant geological data they were interested in in in their spare time, sometimes aimlessly, but found new geological knowledge or minerals in them. Geological work in geological jobs is often a task assigned by superiors. I work around topics all day and take care of my interests. Now I can make use of the unique "Taobao" condition of managing geological data and do my own research in my spare time. So the in-depth compilation of geological data appeared.
In-depth compilation and research needs to link geophysical prospecting, drilling, laboratory analysis and other geological data of independent units to create new achievements, which will make it more convenient for geological technicians to use geological data, which belongs to the improvement of data utilization services; In-depth editing research needs to find new highlights in another way of thinking.
(A) the main points of in-depth editing research
1. Familiar with this series
Understand the family background of the materials hidden in the archives, and be aware of them. However, to understand the collection, you have to look through the classified catalogue. After reading the classified catalogue, I have a preliminary understanding of the collection, and then I have a detailed look at the secondary catalogue of the data groups I am interested in, making a comprehensive analysis and finding my own interest.
2. Collect feedback from data users
Investigate users' needs, because the management and compilation of geological data serve users. Users need to pay a return visit to investigate and study their needs in using materials. This is also a customer system in modern enterprises. It is very important to meet the needs of users. For example, when an enterprise conducts comprehensive prospecting research, the geological archive will pay attention to and study other minerals in logging information and collect logging information of single-well minerals.
3. Observe physical data
According to the points of interest, select the physical data you need to know, carefully observe the core cuttings in the field, and check the experimental test reports made by these physical data in the past to determine whether the points of interest have practical value.
4. Get leadership support
For the target of interest points with practical value, detailed data analysis is made to form a preliminary plan, and efforts are made to win the support of leaders and project management departments.
5. Establish a project and get financial support.
Without financial support, in-depth editing and research will be limited. Striving for project approval is the source of financial support. For in-depth compilation and research, it may not be enough to rely on existing materials for new integration. It is often necessary to further collect relevant geological data that museums do not have. If it is mineral resources, it is necessary to investigate the market demand, then invest some new geological workload to verify the reserves, and if necessary, take samples for specific laboratory tests to study the feasibility, cost and benefit analysis of mineral development and environmental protection.
In the copper polymetallic mining area in Gudong Uzhumuqin Banner, Inner Mongolia Autonomous Region, different exploration teams, such as non-ferrous geological departments, carried out geological and geophysical exploration work in different periods, and each formed some geological data. Geological data management or geological technicians go out to collect all relevant data separately, which makes up for the lack of their own collection. Based on the comprehensive analysis of geophysical and geochemical data in this area, eight targets and parts with great prospecting prospects, such as copper, lead, zinc and silver, have been selected. On this basis, the unit launched field investigation, market research, environmental certification, and finally established the project.
(b) In-depth compilation of major types of results
1. Result chart
Understand the past work degree of this area and draw up the exploration degree map. Such as: exploration well map in lower Yangtze area, geophysical prospecting degree map in Yangtze area, etc. Some units have compiled the Exploration Graphic Database, which has played a role in the exploration and development degree, research and management of the mining area, and the relevant departments have highly praised it, greatly improving the utilization rate of the compilation and research results.
2. The second explanation
Use new equipment and technology to reprocess or interpret historical data and correct the original interpretation results. Secondary interpretation mainly refers to the reprocessing and interpretation of 2D data and 3D data in geophysical exploration work area and geophysical logging data. Due to the continuous progress of technical software and processing equipment, re-processing or re-interpretation can produce new discoveries, new understandings or new thinking in the original exploration field. Re-processing or reinterpreting historical data broadens the original exploration ideas and expands the cognitive scope of mining areas.
In 200 1 year, Dagang Oilfield consulted the well history data of more than 600 wells, obtained 80,000 pieces of data information from the development database, re-evaluated and comprehensively analyzed the historical data through new technologies, new methods and new ideas, found 964 microstructures, and changed the interpretation conclusions of 233 wells, which provided a basis for the proposal of 85 new well locations.
3. Geological report of new deposit
Discover new minerals in geological data and compile new mineral geological reports. For example, a mineral enterprise in East China is a professional team of oil and gas exploration, and has accumulated a lot of oil and gas geological data in its work. They found that the oil and gas logging map showed other mineral signs, such as the abnormal oil and gas data in Jintan, Jiangsu Province, rather than oil and gas signs, so they looked at the core of Well Jin 7 and found the sodium chloride deposit. 1997 organized detailed consultation, set up special research, and successively compiled the Geological Report of Jintan Salt Mine Exploration and the Certification Report of the First Mining Area of Jintan Salt Mine. 1983 Based on this advantage of mineral resources, relevant local governments in Jiangsu have built a vacuum salt-making plant with an annual output of 3 million tons. 198 1 year, a geological structure similar to "salt dome" was found in Subei 1 area from more than 30 seismic profiles in the same unit. After careful study and analysis of all geological data in this area, the unit initiated the project "Study on geophysical characteristics and geological conditions of salt-forming potassium prospecting in Huai 'an-Hongze area of Subei Depression". The research results show that the reserves of sodium chloride deposits in this area exceed 250 billion tons. Leave it to local development and utilization. Oil field enterprises in East China have carried out in-depth development of petroleum exploration geological data, set up special studies, and found out three major salt mines, Jintan, Huai 'an and Hongze, and Huangqiao large-scale carbon dioxide gas field. The development of these minerals has promoted the development of a number of township enterprises and the emergence of corresponding local industrial clusters, and the upstream and downstream enterprises of industrial clusters have provided "chain" employment opportunities for the local area.

A geological survey institute in Shandong was originally a mineral survey institution. They used their accumulated basic geological data and a small amount of investigation methods to complete the feasibility study certification report of Shandong No.1 nuclear power plant for Shandong Electric Power Design Institute. This achievement has been highly praised by experts from the National Nuclear Safety Administration and the Ministry of Water and Electricity. Similarly, they also carried out the engineering geological report of Laixi-Jiaonan section of Tongjiang-Sanya Expressway, the agricultural eco-geological survey of Dongying City and the results of environmental geological survey in related areas.
Jiangxi non-ferrous geological prospecting introduced new technical indicators to develop old data, which made the "substitute mine" reborn. For example, Zhuangwan placer gold mine in Jingdezhen, Jiangxi Province was discovered in 1950s, when the ore body was delineated by the industrial index of rock gold mine. The conclusion shows that the ore body is low-grade and dispersed, and has no industrial value. In the 1980s, they introduced the production indicators of gold miners, re-studied the data, and found that most of the ore bodies met the requirements of industrial indicators, and wrote the industrial vision plan of the ore points. After 1985 was put into production, it brought huge economic benefits to the local area and became the pillar mine of the gold industry in Jiangxi Province.
Henan Nonferrous Geology and Mineral Resources Bureau has a large number of geological data for general survey, and cement marl has been found in the geological data for non-ferrous exploration. So they made a detailed investigation of a cement marl project in the mountainous area of zhenping county, and compiled a geological exploration report of cement marl, with proven reserves of more than 30 million tons. Later, they built a large cement production base with a daily output of 2,500 tons.
Geological data management units or departments can also establish geological data utilization consulting files, accumulate standard answers, and take the initiative to make statistical analysis of users' utilization of "target" data, and carry out targeted tracking services. Information consulting service emphasizes pertinence, timeliness and accuracy.
The in-depth compilation and research of geological data coincides with the contemporary knowledge service.
