摘要

大港油田南部官984地区孔二²油组属低渗透油藏, 由于该断块构造落实程度低, 储层物性差, 油井自然产能低, 一直未能投入开发。2004年老井复查, 对该块重新进行了构造精细解释, 结合储层、测井、油藏特征及油藏工程综合研究, 认为该断块具有有利的油气富集条件, 先后在该地区部署评价井2口, 压裂后获高产油流, 在此基础上编制了整体开发方案。经整体压裂获得了较高的单井产能, 实现了整体探明整装投产。

Abstract

Kong2² pay zone o f Block Guan 984 in DagangO ilfie ld is
a low pe rm eab ility o ilfield. Because the geo log ica l structure is
not determ ined, the reservo ir cha racter istics are poo r and the
natural productiv ity is low. The block has not been developed
since guan 984 we llw as drilled. From Apr il 2004, a ser ies o f
researches have been m ade on d ifferent aspects such as 3- D
se ism ic rein terpretation, reservo ir distr ibution, logg ing
eva luation, reservoir charac teristics and reservo ir eng ineer ing
comprehensive research. It is cons idered that this block is
rich in o il- gas accumu la tion. Tw o eva luating we lls w ere
