焉耆盆地宝浪油田宝北区块构造特征再认识
|
摘要
宝浪油田宝北区块属高陡背斜构造发育区,区内断裂及裂缝及其发育,构造复杂。综合利用构造、地震、岩心等资料,对该区构造特征进行再认识。研究表明:宝北区块背斜构造是在垂直于背斜轴部的强烈挤压力作用下,即由反冲断层产生的走滑作用而形成的。由于受力不均,宝北背斜大致可以分为三段:南东段、相对较粗的北西段、较细的中段。通过最新钻井资料所编制的构造图,对该区三级断层进行重新认识。根据定向取心、成像测井、常规岩心及薄片资料,对裂缝特征进行了分析,并利用古构造应力场数值模拟预测裂缝。最终确定裂缝的发育分布带。裂缝综合预测与实际应用结果具有较高的一致性,可为下一步勘探部署提供依据。
The structure of Baolang oilfield is a high steep anticline,faults and fractures mostly developed,structure complexity in this arear.Based on the structure,seismic,and core data,structural features at Baobei block are recognitioned.After study: anticlinal structure at Baobei block is formationed by the strong pressure which is vertical to anticline axis.In other words,it is caused by the strike slipping of back thrust;because of the uneven stress of pipeline,it has been divided into 3 parts,SE and NW are relatively large,the Middle part is relatively small.According to tectonic map,third-class faults have recognioned.Based on the data of directional core drilling,FMI,routine cores and their thin-sections,the characteristics of fracture.after prediction fracture by numerical simulation of palaeotectonic stress field are described.The distribution of fractures is finally defined.The fractures predicted by comprehensivemethod are highly consistent with practical result,therefore can provide reference for future exploration deployment.
