以重磁力资料为基础，结合钻井及地质地震资料，推测出研究区有8条基底断裂。已有油田大都沿基底断裂走向分布在断裂两侧，勘探井的试气产量高低与基底断裂分布关系密切，基底断裂的“隐性”活动导致沉积盖层中发育构造裂缝且以垂直裂缝为主，裂缝不仅能作为油气运移的通道，而且能提高储层的孔隙度和渗透率，对研究区内油气分布及储层产能起关键作用。

Based on gravity and magnetic data and combining with data from drilling, geology and seismography, eight basement faults are inferred in the research area. Existing oil fields are mostly distributed at both sides of the basement faults in strike trend. Trial gas production from exploration wells is closely related to the distribution of the basement faults. " Hidden" activities of the base- ment faults resulted in the structural fissures vertically developed in sedimentary cover. The fissures could be channels for oil and/or gas migration and also increase the porosity and permeability of oil reservoirs, which would be pivotal in oil/gas distribution and productivity of oil reservoirs in the re- search area.
