First, implement the high-tech strategy and undertake major projects of the national "863" high-tech plan.
The national "863" plan established a major project "Key Technologies for Exploration and Development of Bohai Oilfield" in the field of resources and environmental technology. In order to complete the research task of this major project, Vice Minister Li of the Ministry of Science and Technology signed a cooperation agreement with Deputy General Manager Luohan of China Offshore Oil Corporation on June, 2009 19 * *. China Offshore Oil Corporation took the lead in undertaking nine topics of this major special project and the technical theme of marine resources development:
A. offshore time-lapse seismic reservoir monitoring technology. The main purpose of seismic monitoring technology in oilfield development is to dynamically monitor the changes of reservoir fluid properties in time and space, provide accurate information for adjusting and optimizing development plans, and find the distribution of remaining oil at the same time, so as to improve crude oil recovery and reduce production costs.
B. controllable three-dimensional trajectory drilling technology. Aiming at the international frontier drilling engineering technology, this technology has developed a set of rotary steering drilling system and multi-branch completion tools. Through this technical research, three-dimensional trajectory drilling and multi-lateral well completion can be carried out under the conditions of multi-wellhead platforms and complex underground reservoirs in Bohai Sea.
C EOR technology for deep profile control and flooding in Bohai Oilfield. Research on EOR technology in Bohai heavy oil field is carried out from the following four aspects: ① development of production logging tool for gravel packing sand control wells; ② Reservoir protection technology in the production process of Bohai Oilfield; ③ Depth profile control technology after water flooding in Bohai Oilfield; ④ Offshore polymer injection technology. Among them, offshore polymer injection technology is a national 863 project, which mainly develops instant, salt-resistant composite and associative polymers.
D. Anti-ice vibration technology of Bohai platform. In winter, the sea surface icing in the northern Bohai Sea will cause the vibration of offshore platforms and bring danger. The research of anti-ice vibration offshore platform is based on ice load experiment and platform vibration isolation technology, so that Jinzhou 20-2 North Platform can achieve the purpose of anti-ice vibration.
E. oil and gas reservoir testing technology in the middle of drilling. In order to find and evaluate oil reservoirs early during drilling and reduce the cost of exploration and development, it is necessary to establish a set of comprehensive formation tester suitable for Bohai geological conditions, which partially replaces oil testing and drill pipe formation testing.
F external detection device and detection technology of submarine pipeline. By developing optical fiber sensor to detect submarine pipeline in real time, the suspended span of washed submarine pipeline is determined. Non-contact measurement of cathodic protection potential of submarine pipeline; In muddy water, underwater laser imaging system can be used to observe the damage of pipelines exposed to 300 meters water depth.
G. Key technologies of ultra-large floating production and storage system in shallow water. The development of Penglai 19-3 oilfield in Bohai Sea needs a super-large floating production and storage system, but the biggest technical problem in building a 300,000-ton super-large floating production and storage system is shallow water because the water depth in Bohai Sea is only 20 ~ 30m. In this case, the problem of shallow water effect is finally solved through the research and experiment on the motion characteristics of FPSO.
H. submarine pipeline repair technology. By developing the underwater dry pipeline maintenance cabin, the pipeline can be cut and repaired automatically without stopping production.
1. Seismic exploration and identification technology of complex natural gas reservoirs in the East China Sea shelf basin. The geological conditions in the East China Sea Basin are complex, and natural gas exploration has encountered the technical problem of how to effectively identify natural gas reservoirs by geophysical exploration methods. This technology will study the "multiple waves" on the seabed and finally establish a natural gas reservoir identification system for seismic exploration.
Two, the "Tenth Five-Year Plan" key projects will solve major key technical problems such as offshore natural gas exploration and Bohai heavy oil development.
The key research project of China Offshore Oil Corporation in the Tenth Five-Year Plan is a comprehensive research project aimed at major issues such as offshore natural gas exploration, Bohai heavy oil development and deep water exploration and development. Part of the project or part of the project content has been applied for the national 863 high-tech project. In order to complete the research tasks of various projects and make major technological innovations, China Offshore Oil Corporation signed the Tenth Five-Year Scientific and Technological Cooperation Agreement with China Academy of Sciences, and set up a major project of "Research on Some Scientific and Technological Issues of Offshore Oil Development" in China Academy of Sciences. Key research projects of the Head Office mainly include:
A. Feasibility study on high production development with fewer wells in Bohai heavy oil field. How to realize high production with fewer wells and minimize development cost in offshore heavy oil fields? This project studies the development effect of land-based developed oil fields such as Dagang and Shengli, and then carries out virtual development of offshore developed oil fields. Through the research and practice of horizontal multilateral wells, a new development scheme can be put forward for undeveloped oil fields to realize less wells and high production.
Study on reservoir protection technology of drilling and completion in Bohai Oilfield. By studying the damage mechanism of heavy oil reservoir, the development of low density cement slurry system and aggressive completion fluid with low (no) oil and gas reservoir damage during drilling, cementing and completion is completed.
C. study on fine reservoir description of heavy oil reservoir. The Paleogene in Bohai Sea belongs to fluvial deposits, and the vertical and horizontal changes of reservoirs are great, which brings great difficulties to reservoir description. By studying the relationship between petrophysical parameters and geophysical characteristics in the study area, as well as the vertical and horizontal variation laws of seismic velocity and sedimentary facies, a fine reservoir description method and software are established.
D. the third round of oil and gas resources evaluation in the whole sea area. In this paper, the third round of oil and gas resources evaluation in China sea area is carried out by using the resource evaluation method (UAGE) of the United States Federal Geological Survey, and the recoverable resources under the current technical conditions are calculated.
E. Study on cementing technology for high temperature and high pressure formation in Yingqiong Basin, South China Sea. Based on the research of drilling technology in high temperature and overpressure formation in South China Sea, the cementing technology in high temperature and overpressure formation was formed through the research of double-effect anti-gas channeling cement slurry system and the development of anti-gas channeling packer.
F. Research on exploration technology of large and medium-sized natural gas fields in China offshore. Offshore natural gas exploration depends on the progress of geophysical exploration technology to a great extent. Through the study of seismic parameters and special processing methods in the exploration area, the key problems in natural gas exploration in the South China Sea and the East China Sea are mainly solved.
