舍女寺油田女20断块造位于黄骅坳陷南区的舍女寺构造西北台阶带,孔二段油组为一典型的高压、低渗透油藏,储层平均孔隙度19%,渗透率5×10-3μm2,投入开发以来,注水井欠注现象严重,历史上曾多次开展水井的降压增注工作,但效果均不理想。因此,在欠注机理研究基础上,转变思路,寻求突破,大胆尝试超高压增注技术,提高断块开发水平。 Female Nuozhan fault block female female section 20 is located in the southern Huanghua depression Shexianmiao structure northwest step zone, Kong 2 section of the oil group is a typical high pressure, low permeability reservoir, reservoir average porosity of 19%, permeability 5 × 10-3μm2. Since the project was put into development, the phenomenon of under-injection in injection wells has been serious. In history, the wells have been depressurized and re-injected repeatedly, but the results are not satisfactory. Therefore, on the basis of the research on under-injection mechanism, we should change our thinking and seek breakthroughs and boldly try UHP injection technology to improve the development level of fault block.
