【摘要】：针对乌石凹陷陆相断陷湖盆物源体系复杂、相变快,难以寻找、预测优质储层分布这一亟待解决的关键问题,开展了断裂演化期次、断层剖面平面活动差异性及沉积体系精细研究。采用海上陆相复杂断块断层精细识别解释、微地貌恢复及相控储层预测等关键技术,获得了研究区内3条北东向控沉积断裂差异性活动形成的走向斜坡具有控制砂体优势展布的重要认识,提出了源一汇时空耦合的控砂模式,预测了F_2断层下降盘发育优质储层。在此研究成果的指导下,新钻井获得重大发现,极大地推动了乌石油田群的勘探开发进程。
[Abstract]:In view of the complex provenance system of continental faulted lacustrine basin in Wushi depression, which is difficult to find, and to predict the distribution of high quality reservoir, this paper develops the stage of fault evolution. The difference of planar activity of fault profile and fine study of sedimentary system. The key techniques such as fine identification and interpretation of faults in marine continental complex fault blocks, microgeomorphology recovery and facies controlled reservoir prediction are adopted. The important understanding that the strike slopes formed by the different activities of NNE controlled sedimentary faults in the study area have controlled the dominant distribution of sand bodies has been obtained, and a spatial-temporal coupling model of source-sink sand control has been put forward. Under the guidance of the research results, the important discovery of the new drilling has been made, which has greatly promoted the exploration and development process of the Wushi oilfield group.
