塔里木盆地玉北地区断裂带控藏特征研究
|
摘要
从解剖塔里木盆地玉北地区玉北1断裂带构造特征与油气源入手,重点分析影响玉北1奥陶系油气藏产量(停产前油气累计产量)的主要地质条件,如钻井所处的鹰山组顶面(T57)的构造位置、鹰山组孔洞缝型储层发育特征、鹰山组T57界面主次级逆冲断层的变形强度以及油气藏与断层之间的距离等;同时,对同处玉东3断裂带上钻探的玉北3和玉北3-1井失利原因开展对比分析。分析认为,玉北地区奥陶系油气成藏富集主要受鹰山组顶面的构造位置及其优质储层的共同作用,其中构造位置是油气藏产量更为重要的控制因素。构造位置过高可能导致其缺失巴楚组泥岩段优质盖层以及海西晚期断层断开层位过高,保存条件差是玉东其他断裂带钻井未获油气的主要原因。
The structural features and oil and gas sources of the Yubei 1 fault belt in the Yubei area of the Tarim Basin were studied to determine the main geological conditions affecting the production of the Yubei 1 Ordovician oil and gas reservoir( the cumulative oil production before shutdown). Factors considered included the tectonic position of the top surface of the Yingshan Formation( T57) where wells were located,the development characteristics of fractured and vuggy reservoirs of the Yingshan Formation,the deformation strength of the main and secondary thrust faults of the T57 interface,and the distance between reservoirs and faults. Combined with the main reasons for the failure of the wells YB 3 and YB 3-1 in the Yudong 3 fault belt,east of Yubei,it suggested that the structural location of T57 and high-quality reservoirs were crucial to hydrocarbon enrichment in the Ordovician in the Yubei area. The structural location was a more important controlling factor for the production of oil and gas reservoirs. However,an excessively high structural location may cause the lack of overlying strata and the exposure of faults in the Late Hercynian,which lead to unfavorable petroleum preservation conditions.
