东辛中油田属典型的复杂断块油田,其地质特点表现为构造复杂,断层多,断块碎;储层发育纵向变化大;油层物性、原油性质差异大。开发特点为多套层系开发,层间差异大,油层连同性差,储量动用不均衡,注采对应率低。该地区“三低井”数87口,平均单井
The Dongxinzhong Oilfield is a typical complex fault block oilfield. Its geological features are complex structure, multi-faults and broken blocks. Longitudinal variation of reservoir development is large. There are big differences in physical properties and crude oil properties of the reservoir. Development characteristics for the development of multiple sets of strata, large differences between layers, the reservoir together with the poor, unbalanced use of reserves, injection and mining correspondence rate is low. The area “three low wells ” number 87, the average single well
