尕斯库勒油田是柴达木盆地目前开发的主力油藏之一,作为有效动用新增地质储量、实现建产目标的有利区,该油田N1—N21油藏下盘南区储层分布井段长,油砂体平面分布连续性差,油水关系受岩性控制明显,给油藏开发带来了一定的困难。通过老井资料复查,结合钻井、试油试采资料,以地质、测井等学科方法开展储层地质特征综合研究,进而搞清油水关系,在“钻前评价、过程跟踪和深化认识”滚动开发实践中取得了较好的效果,对改善研究区和同类复杂岩性油藏的开发具有一定的指导意义。
Gasseule Oilfield is one of the main reservoirs currently under development in the Qaidam Basin. As a favorable area for effective utilization of newly added geological reserves and production targets, the South Well Reservoir Reservoirs in the lower N1-N21 reservoir The interval length of the segment, the continuity of the plane distribution of the oil sands body is poor, and the relationship between oil and water is controlled by the lithology, which brings some difficulties to the reservoir development. Through the review of old well data and the combination of well drilling and test oil production data, a comprehensive study of reservoir geological features was carried out by means of geology and logging and other disciplinary methods to further clarify the relationship between oil and water. In the pre-drill evaluation, process tracking and deepening understanding, "Rolling development has achieved good results in practice, to improve the study area and the development of similar complex lithology reservoir has a certain significance.
