北三台凸起多边断层对油气成藏的影响
The Effect of Polygonal Fault in Beisantai Bulge on Oil and Gas Accumulation
摘要
Abstract
In order to investigate the effect of fault in Beisantai bulge in Junggar basin on oil and gas accumulation, the development characteristics,forming mechanism and their relationship with reservoirs are described and dis-cussed,based on seismic interpretation,regional structure,lithological association,clay mineral composition, pressure distribution and known reservoir characteristics. The results show that the fault is a typical polygonal fault, with"vertical strata-bound attribute"and"planar polygonality",which are formed by fine-grained sediment un-der density inversion effect. The lower part of the formation where polygonal faults are developed is close to source rock in Pingdiquan formation,Permian System and acts as migration pathway during oil and gas accumulation. The dense spatial fault network provides conditions for local connectivity of reservoirs and the interpretation and analysis of polygonal fault should be strengthened during fine exploration. The research provides guidance for oil and gas pro-gressive exploration and reservoir fine evaluation in Beisantai bulge.关键词
