摘要

在调剖施工中,采用笼统管柱还是分注管柱,争议较大。以中原油田近解远调、絮凝体系为例,通过对2种体系的组成、作用机理、最佳使用配方进行研究,笼统、分层调剖增油效果进行对比,结果表明:由于调剖堵剂的智能性作用,笼统调剖效果好于分层调剖。根据这一结论指导2005年分注井的调剖工作,取得了良好的效果,使水井措施结构更趋合理、科学。

Abstract

there are a lot of disputes on the choice of nontarget or separated zone profile control strategies. For the near-wellbore decompose and farther-zone plugging flocci system, the composition, mechanism of action and optimized formulary of both nontarget and separated zone system were studied. By comparing the oil increasing extent of the two systems, we found that the nontarget profile control system was better than the separated zone profile control system. The potential reason may be due to the intelligent function of profile control plugging agents. Under the guidance of the study, the profile control operations in Zhongyuan oilfield had gained great effect.
