断层边部由于侧向遮挡多形成注采不完善区域,同时水下分流河道砂体与断层相交形成背斜控制下的断层-岩性油藏,断层边部的厚油层顶部属于低水淹层,多形成剩余油富集。应用构造解释技术,结合钻井、测井、试油、沉积相等资料,通过细致描绘葡北油田X井区油层组顶面构造特征,预测目的层的砂岩分布形态、厚度和展布范围,可为井位设计、投产提供地质依据。 At the edge of the fault, more lateral faults are formed to form imperfectly injected and reclaimed areas. At the same time, the submarine distributary channel sand body intersects the fault to form a fault-lithologic reservoir controlled by the anticline. The top of the thick oil layer on the fault margin belongs to the low water flooded layer , Forming more residual oil enrichment. By means of tectonic interpretation technique and combined with drilling, well logging, test oil and sedimentary equivalent data, the sandstone distribution pattern, thickness and distribution range of the target layer can be predicted through the detailed description of top structural features of the oil layer in Well X of Pubei Oilfield. Well location design, production to provide geological basis.
