摘要

随着油田开发进入后期, 层间矛盾越来越突出, 分层注水工艺是目前解决层间矛

盾最有效、最经济的一种途径。针对江苏油田储层物性差, 非均质性较强, 夹层薄, 斜井多, 井

斜大等特点, 目前所采用的偏心、液力投捞分注工艺不能满足于小卡距、大斜度和同位素测试

要求, 为改善层间矛盾, 提高开发效果, 研制了一种新型空心分注工艺, 有效解决了薄夹层、大

斜度井的分注难题, 并在现场的应用过程中取得了良好的应用效果。

Abstract

A t late r stage of o ilfie ld dev elopment, the in terlayer
conflicts arem ore and m ore prom inent. As w e a ll know n, the
technique o f separate layerw ate r injection is them ost e fficient
and econom ica l approach to so lve the interlayer conflic ts.
A im ed a t the poor reservo ir physical prope rties, strong
an iso tropy and thin inter layer, excessive inc lined w ell and b ig
w e ll dev ia tion, the adopted techn ique o f separate layer wa ter
injection presently can ’t sa tisfy the sma ll chuck d istance and
larg e degree of inc lination. In orde r to im prove the in terlayer
conflicts and enhance developed effec t, th is pape r dev elops a
m odern technique of ho llow separate layer w ater injection,
w hich can ava ilab ility so lve the encoun tered problem and
acqu ire a good effec t in field applied process
