大庆长垣北部萨、葡、高油层北东向断层成因及对油田开发的作用
|
摘要
大庆长垣北部喇、萨、杏油田萨、葡、高油层的断层走向以北西走向为主,北东向断层数量较少且呈雁列式集中分布,2种断层彼此交切,形成封闭或半封闭复杂断块。以往对北东向断层认识不清,注采关系不完善。通过对断层的分期研究,认清了北东向断层集中雁列式分布的成因和北东向、北西向断层交切组合模式,并进行了复杂断块区的断层精细解释。根据新的井震结合断层精细解释结果,编制了NEX区西部断块区优化布井方案,部署二类油层聚驱井、二次加密井补充井28口,其中14口二类油层聚驱井初期平均单井日产油28. 7 t,断层附近剩余油挖潜效果显著。
The faults in Sapugao reservoirs of Lasaxing Oilfields in Daqing Placanticline are mainly characterized by NW strike while the amount of NE fault is rather less and moreover centrally distributed in the pattern of the echelon. The two kinds of the faults are intersected with each other,which results in the formation of the closed or semi-closed complex fault blocks. The latter was not be clarified before and furthermore the injection and production relationships were not perfect. With the help of the staged researches on the faults,the genesis of the latter in the distribution and the intersected-combined pattern of the former were made clear,and then the fine interpretation of the faults in the complex fault block was conducted. According to the results of the fine interpretation for the new well-seismic combination,the optimized well arranging program was compiled for the western region in Block NEX,total 28 wells were arranged for the second-level reservoir polymer flooding and the secondary infilling addition,the initial average daily oil production of the 14 polymer flooded wells is 28. 7 t,the potentials of the remained oil near the fault were tapped,and moreover the benefits were obvious.
