【摘要】：體積壓裂是致密油藏開發(fā)的重要手段之一,是隨致密油氣藏開發(fā)成長起來的一項新技術(shù)。文中為了提高已開發(fā)致密油藏的開發(fā)效果,將體積壓裂理念引入已開發(fā)的老油田。針對長慶油田A3區(qū)塊長7致密油藏,重點開展了應(yīng)力模型計算、物理模擬實驗、壓力測試分析和井下微地震監(jiān)測等研究,明確了老井體積壓裂裂縫的延伸機理,確立了老井暫堵混合水壓裂體積壓裂技術(shù),現(xiàn)場試驗取得了較好的效果,為類似油井重復(fù)改造提供了新的技術(shù)手段。
[Abstract]:Volume fracturing is one of the most important methods for the development of tight reservoirs, and it is also a new technique developed with the development of tight reservoirs.In order to improve the development effect of developed compact reservoirs, the concept of volume fracturing is introduced into the developed old oil fields.For Chang7 tight reservoir in A3 block of Changqing Oilfield, stress model calculation, physical simulation experiment, pressure test analysis and downhole microseismic monitoring are carried out, and the extension mechanism of volume fracturing fracture in old well is clarified.The fracturing technology of temporary plugging and mixing water fracturing in old wells has been established, and good results have been obtained through field test, which provides a new technical means for repeated revamping of similar oil wells.
