港东油田二区六断块构造比较完整，属复杂断块中构造较简单的区块。油层主要集中在上第三系明化镇组下段和馆陶组顶部，馆陶油组为典型的边底水油藏。1969年投入开发，经历40多年的开采，目前已经进入高含水后期开发阶段，断块的综合含水高达95.8%，含水在90%以上井，基本上集中在主力砂体。由于直井开发水锥现象严重.开发状况不断恶化，导致采收率低，大量剩余油滞留地下无法采出。针对该油藏地质特点和开发状况，对馆陶组底水油藏进行综合研究选定剩余油富集的有利目标区，进行层系划分、井型井网论证。对水平井开发挖掘厚油层顶部剩余油开展参数论证，并优化应用。对比分析区块调整前后指标变化特点，总结边底水油藏剩余油挖潜规律，为同类型油藏的高效开发提供经验和借鉴。

Gang Dong oilfield,the block six of No. 2 area structure complete,It is a simple block in complex block. Reservoir are mainly concentrated in neogene of Ming town,top of the group of lower segment and guantao,Guantao formation served oil group is a typical bottom water reservoir. Develop the year 1969,through more than 40 years ex-ploration,has entered the late high water cut development stage at present,fault block of composite water cut is as high as 95. 8%,more than 90% of the water in Wells,largely concentrated in the main sand body. Due to vertical well development of water coning phenomenon is serious,deteriorating development situation,lead to low recovery efficiency,a large number of remaining oil trapped underground cannot be produced. For the reservoir geological characteristics and development situation,comprehensive research of guantao bottom water reservoir with the select-ed target zone of enrichment of remaining oil,type classify strata and well pattern. Demonstrate the parameters of the horizontal well development mining thick oil layer at the top of the residual oil,And optimize the application. Con-trast analyzing the characteristics of the block adjustment indicators before and after the change,summarizes the law of remaining oil potential in bottom water reservoir,for the efficient development of similar reservoirs provide experi-ence and reference.
