摘要

本文评述了近几年在文东油田近开地带解除盐堵的研究、应用成果,主要是化学解堵剂的筛选、评价及包括向地层挤化学药剂解堵、连续接水微渗透淡化解堵、过桥系结合化学药剂冲盐解堵等一套解堵技术。

Abstract

Salt plugging position makes a slow descent until tunnel or fracture of formation with the decline of formation pressure,and then causes cricital plugging.This paper introduces the research and application achievements in Wendong Oilfield in recent years,which include screening and evaluation of chemical plug removal agent,chemical plugging technique,micropermeation desalination plug removal technique by continuous water feeding,gap bridge pump and chemical reagent flushing plug removal technique.
