Exploration Potential: Reveal The Truth Buried Oil And Gas by jekky

Expert voice: "Our pursuit is to approach the maximum ground truth." Exploration and Development Institute, said Chief Expert Mu small water.



"Looking for reserves is to find food." Speaking of the importance of oil and gas exploration, Geophysical Institute, chief expert Liu Zhongliang said.



"As long as the ideology is not aging, old liberated areas have youthful exuberance." Exploration Management Planning Section exploration exploration exploration for old host XU Jun-jie on confidence.



After 30 years of exploration and development of the Depression, becoming more exploration, more and more low single well controlled reserves, increasing reserves blocks of small, broken, deep. But in recent years oil field in eastern sag adhere to the guidance for detailed exploration of the implementation of integrated exploration and development operations, the new block close to the zone proved reserves, proved reserves of high quality, level of reserves available from 65% to the current 93% of the overall efficiency of exploration and development of improved, as reserves to ensure stability Dongpu key factor.



Adhere to deepen the basic research to guide the micro-macro analysis of reservoir distribution, and gradually understand the ground truth



"We are currently facing the main exploration targets in the complex layer structure, fracture zones, under the deep depression, construction plunge end and junction, detailed exploration is the only option." Exploration and Development Institute of Survey and planning director Jia Yan ? said.



However, the precise exploration does not mean "small", the opposite is more necessary for macro strategies and theories for guidance. Jia Yan? That, if not to give priority to basic research, but the blind pursuit of the so-called "small" and "small", the point was kept after the result is often "Mangrenmoxiang" can only get some one-sided.



To basic research objectives, oil has in the "civilized Walled regional fracture reservoir characterization and reservoir prediction," "East sag Salt Lake sedimentary basin, sand 3 sand system and control mechanism", "Western Slope faults on sedimentation and hydrocarbon accumulation in the role of "" Pu Wei Depression vaginal discharge of hydrocarbon accumulation mechanism and distribution "," horse factory area of fault systems and structural transformation "gained a new research.



Particularly in recent years carried out a "complex fault blocks east sag potential oil and gas exploration and objective evaluation" as the subject of basic research, but also played a micro-macro theory to guide the role of technical operations. Oil geologists through the application of the concept of fault blocks and ideas, zoning, zoning, classification based on the depression forming to study law, to establish a suitable complex fault blocks Dongpu depression reservoir real exploration of the theoretical system, the East sag stable resource base of deepening established 8 accumulation model, the basic grasp of the various fault blocks of the reservoir model and various fault blocks the main controlling factors of enrichment and distribution of the effective guidance of the fine old oil field exploration.



Law once mastered, it is precise evaluation of complex fault blocks Dongpu old liberated areas, and actively explore the new area with new layers and new types of oil and gas reservoirs, oil and gas buried underground to find the truth and understanding to provide the theoretical support.



Is complex fault blocks according to established oil and gas reservoir evaluation criteria, in recent years, oil field in East sag implemented 40 fault blocks, 477 block and 128 million tons of trap resource to further strengthen the field to achieve stable growth Dongpu depression storage confidence.



Big problem is complicated further by the simple accumulation of small problems, is a detailed exploration of Dongpu Category exploration, Sidelights for the whole process



"Delicious pomegranate, seeds difficult to peel," the exploration plan in the exploration, director of the Department of Management Xi Li, mind, anatomy is a pomegranate exploration for old separate the "seed" and "skin" of the process. To this end, Li Chun Hei cited three examples of the West Wing set structure. Their original structure that the West Wing Sanchunji relatively far away from the oil source, trap types to the formation of reverse faults dip east block, oil and gas enrichment poor, less exploration, not be evaluated. 2009, oil use target processing seismic data set of three spring structure and sediment 3, 2, 3 sand and sand under the top three lines for the next 4 overall evaluation of the three layers, the implementation of the 13 favorable drilling targets. While drilling the reservoir evaluation in the West Wing Chun 9-50 Well well, spring 16 side of the well were three in the sand, sand three times daily output of 23 tons and was 15 tons of high-yield industrial oil flow, show good exploration of the structure development prospects.



The face of domestic oil fields east of the most complex, technical staff to realize that the complex is not terrible, terrible is not found the means to solve complicated problems.



Category exploration, Sidelights exploration work for the whole idea, no doubt a large oil field exploration and field staff to resolve numerous conflicts Dongpu "weapon."



Hand this "weapon" to complex fault block oil reservoir forming Theory, formulated the "persist in relying on the old liberated areas, to find a good forming conditions; adhere to the hierarchical system evaluation as a means to find enrichment; adhere to the detailed anatomy of the core reservoir, looking for implementation; adhere to the efficiency, look for the shallow; adhere to the three-dimensional seismic data based on quality, take a big look "old liberated areas classification and evaluation of the exploration approach. As a result, oil will seemingly complex scientific Dongpu oil into the relatively simple to conduct a variety of different types of targeted treatment.



Oil has in the central uplift of Dongpu low degree of exploration area in southern New Haw, exploration Sanchunji structure made a breakthrough, vaginal discharge depression in the western slopes made great progress in exploration, in the northern part of the central uplift Wenliu, Castle Construction exploration good results, in Pu Wei, Wen stay, Hu - Qing, Bridge port, New Fok, Ma factory area proved Oil Geological reserves of 28.28 million tons, proved Natural gas Geological reserves of 2.922 billion cubic meters, achieved Dongpu steady growth in proved reserves in old revolutionary bases.
