【摘要】 目的研究腰英台地区裂缝分布规律与油气运聚之间的关系。方法在岩心、分析测试等一性资料对裂缝标定的基础上,提取裂缝测井响应特征,进而对全区裂缝进行全面系统的测井解释,然后结合钻井、压裂等后期动态资料对测井解释的裂缝作核实验证。结果裂缝的发育程度与岩性、层厚和构造因素有关,而断层作用尤为明显。结论腰英台地区裂缝性储层发育段是该区的主力含油层,从储盖配置关系来看,裂缝在油气疏导方面起主要作用。更多还原

【Abstract】 Aim To evaluate the relationship between fractures distribution pattern and oilgas migratory and accumulation in Yaoyingtai Zone.Methods Label the fracture by means of analysing of the drilling core,then select the characteristics of well log response of the fracture to make a systemic and log interpretation of the regional fractures prediction,and attest the interpretation by coupling with the data of drilling and hydrofracturing.Results The devolopment of fractures is correlated with lithologic characteristics and structures of the reserviors,particularly with the development of faults.Conclusion The reserviors with developed fractures are the dominant oil reservior in Yaoyingtai Zone with respect to the relationship between petrolphysics and caprock.It is evident that the fractures play an important role in the process of oil-gas migratory concentration.更多还原
