摘要/Abstract

摘要： 准噶尔盆地东部吉木萨尔凹陷中二叠统芦草沟组致密油尚处于勘探开发初期。在分析芦草沟组致密油试采生产特征、压力特征、渗流特征、递减特征等基础上，对芦草沟组致密储集层的采收率进行了测算。指出，水平井及多级压裂技术是实现致密油经济有效开发的两大关键主体技术；芦草沟组属正常压力系统，压力系数为1.05~1.20；储集层渗流为非达西流，具有一定的启动压力；油井投产后符合双曲递减规律，初期年绝对油量递减在60%左右，预测最终采收率为5.5%

Abstract: The Lucaogou tight oil of the Permian in Jimusaer sag in eastern Junggar basin are in its early stage of exploration and development. In this paper, the tight oil’s characteristics such as production test, pressure, seepage flow and decline, etc. are analyzed, by which the recovery factor of Lucaogou tight reservoir is estimated. It is suggested that the horizontal well and the multistage fracturing are two kinds of key technologies for economically and effectively developing the tight oil; the Lucaogou formation belongs to normal pressure system, with pressure factor of 1.05~1.20; it has an obvious feature of non-Darcy flow and starting pressure; the oil well production performance is accordant with hyperbolic decline pattern; the annual natural production decline rate is about 60%, and the predicted ultimate recovery factor is 5.5%
