摘要

大王庄油田留70断块是冀中地区典型的低渗透油藏,投入开发10多年来,为提高开发效果,多次进行低渗透改造和井网调整。近2年来该油藏改造过程中应用的配套工艺技术主要包括:高能气体解堵压裂、油井浓缩酸酸化、分层酸化解堵增注、油井卡堵水、地面采油注水配套及新工具的推广应用等,分析了各种开采技术的应用状况和取得的效果。

Abstract

Within the past more than 10 years, Liu 70 fault-block of Dawangzhuang oil field, the typical low permeability reservoir in Jizhong area, has been stimulated for wells and modified for well network time and again to improve development effectiveness. This paper reviews the production techniques applied in the reservoir stimulation in the past 2 years, which include high energy gas fracturing, oil well acidizing using gelled acid, plugging removal and injection stimulation by separate zone acidizing, water control of oil well, surface technology for production and injection, and application of new downhole tools etc., and analyses the application results of each production technology.
