There are 65 geological logging teams, equipped with 5/kloc-0 sets of comprehensive logging instruments, 7 sets of gas logging instruments, 7 sets of PK+OFA analyzers, 0/0 sets of geochemical logging instruments and 0/8 sets of drilling logging instruments. There are 24 logging and perforating teams, equipped with 5700 MRI logging system 1 set, 3 sets of 3700 numerical control logging system, 52 1 set, 9800 numerical control logging system 1 set and DCLS-2000 production logging system/kloc-. This branch has invested in the development of 13 oilfield. There are 1 1 oilfields in the eastern oil region, including 8 rare oilfields and 3 heavy oilfields. The crude oil produced is low sulfur paraffin-based thin oil and asphalt-based heavy oil. Two oil fields in the western (Xinjiang) oil region produce light black oil. Oilfield development methods include water injection, steam injection and partial polymer flooding. There is a set of matching technologies and processes suitable for the development of small and medium-sized basins for sandstone reservoirs with heterogeneous thick oil layers, high pour point oil reservoirs, complex fault-block reservoirs, shallow super-heavy oil reservoirs and volatile reservoirs with low porosity and permeability. Shuanghe Oilfield, the main force, was rated as the national onshore oil efficient development oilfield. Supporting technologies such as high-temperature polymer flooding, comprehensive adjustment of injection-production well pattern at extra-high water cut stage, and shallow ultra-heavy oil reservoir exploitation have won national and provincial scientific and technological progress awards. In the research and guidance of exploration and development, exploration and development research institute, petroleum engineering technology research institute and survey and design research institute have played an active role in scientific research, new technology development and popularization and application.
The crude oil produced in East 1 1 Oilfield belongs to the middle class II after mixing, which has the characteristics of high wax content (average 32.8% in Shuanghe Oilfield), low sulfur content (average 0. 1% in Shuanghe Oilfield), high freezing point and low proportion of light fractions, with an annual output of over 1.7 million tons. The crude oil produced by two oilfields in the west is light, with the characteristics of low density, low viscosity, low colloidal asphaltene, medium and high wax content, medium freezing point and no sulfur, with an annual output of over 654.38+10,000 tons. Zhongyuan Oilfield is one of the most complex fault-block oil and gas fields in China, with broken structure, deep buried oil and gas, low permeability, high temperature, high pressure and high salt. Many exploration and development problems are world-class problems. From 65438 to 0983, the State Council organized a three-year scientific and technological battle in Zhongyuan Oilfield, and many exploration and development technologies reached the domestic and international leading level at that time. In 2003, the petrochemical company organized a new round of 3-year campaign to tackle key scientific and technological problems and solved a number of key technical problems. Two achievements have reached the international advanced level, 17 achievements have reached the international advanced level, 2 1 achievements have reached the domestic advanced level, and 2 1 technologies have obtained national patents, forming a set of comprehensive supporting technologies with the characteristics of Zhongyuan Oilfield. With its technical advantages, Zhongyuan Oilfield successfully completed the drilling and construction task of Continental Scientific Exploration Well 1, a key project in the Ninth Five-Year Plan. In 2008, he undertook five national key scientific research projects and nine key scientific research projects of the group company 19, all of which completed key tasks as planned. The drilling system set five group company records, including the deepest liner and the lowest density of underbalanced drilling fluid, and set eight oilfield records. Breakthroughs have been made in key technologies such as the development of high-sulfur gas fields and the improvement of drilling speed in ultra-deep wells. With the application of gas drilling, gas channeling prevention and cementing technology, the average drilling cycle is shorter than that of exploratory wells by 127 days, and the qualified rate of cementing is 100%. Supporting multi-stage staged delayed initiation perforation technology for high sulfur gas wells, one perforation section spans 594 meters; At the same time, supporting technologies such as temporary plugging technology of high-temperature and high-sulfur gas reservoirs, large-scale multi-stage acid fracturing injection and production, gathering and transportation technology, pipeline construction and welding technology of high-sulfur gas fields with complex terrain have been formed. Progress has been made in slim hole sidetracking and horizontal well technology. The drilling cycle of sidetracking is shortened by 26%, and the drilling speed of horizontal wells is increased by 27%. The seismic exploration technology of supporting swamp transition zone has been successfully applied in Sudan for 4500 kilometers and popularized in Ecuador; Improve the drilling technology of ultra-deep salt-gypsum layer, and successfully drill through 4397 meters thick salt-gypsum layer in Kazakhstan; The development and application of drilling technologies such as multi-bottom multilateral wells and short radius horizontal wells have successfully completed 58 wells in Saudi Arabia. Deep well and ultra-deep well drilling technologies are gradually matched, and the drilling cycle in southwest and northwest regions is obviously shortened. In 2009, there were three national key projects, Zhongyuan Oilfield. First, research on safe and efficient development technology of high sulfur gas reservoirs; Second, the development demonstration project of Puguang large-scale high-sulfur gas field in Sichuan Basin; The third is the study of fine exploration technology in Dongpu sag.
