华北油田低渗透断块油藏改善开发效果配套开采技术

THE ASSORTED PRODUCTION TECHNIQUES FOR IMPROVING DEVELOPMENT EFFECTIVENESS OF LOW PERMEABILITY FAULT-BLOCK RESERVOIR OF HUABEI OILFIELD

“低渗透断块油藏改善开发效果配套开采技术”项目是中国石油天然气总公司确定的“八五”后三年全国油气田开发重点或科技推广项目之一。华北石油管理局从低渗透复杂砂岩油藏中筛选出13个区块，全力投入到项目实施之中。3年来，以经济效益为中心，围绕改善油藏开发效果、提高采油速度、增加可采储量为重点目标，认真编制切实可行的地质方案、工艺技术配套方案和实施方案，依靠初步完善的六大系列配套开采技术，对13个区块进行了综合治理改造，使开发效果得到明显改善。本文重点阐述了六六配套开采技术的推广应用情况及其实施效果，在此基础上，提出了该类油藏提高开发效果的四项建议。

The assorted production techniques for improving development effectiveness of low permeability fault-block reservoir is a major scientific and technical popularization project for nationwide oil/gas fields development during rear 3 years of the 8th Five-Year Plan determined by CNPC. Huabei Oil Administration Bureau selects l3 low-permeability fault-blocks to implement the project. Over the past 3 years,taking the economic benefit as central task,we draw up the geologic,technological plans and enfo1cement programs around improving reservoir development results, enhancing oil production rate and increasing recoverable reserves. The development results of 13 fault-blocks have been impoved by applying six sets of production technology. This paper puts forward four proposals for enhancing development effectiveness of similar reservoir.
