八面河油田提高热采效果的工艺对策

Process Measures for Improving Thermal Recovery Results in Bamianhe Oilfield

八面河油田稠油区块在热采开发过程中反映出热采井回采水率低、防砂有效周期短、水平井热采工艺单一等问题。为提高稠油区块热采效果,有针对性地进行了热采工艺改进试验,通过现场应用证实了其有效性,在些基础上提出了后期热采工艺配套方向。

Such problems as low back--water recovery ratio of thermal recovery wells, short validity period ot sand prevention and single thermal recovery process of horizontal wells arise in the thermal recovery exploitation in heavy crude oil blocks of Bamianhe Oilfield. To improve the thermal recovery results of heavy etude oil blocks, the author did targeted experiments on improving thermal process and the field application proves it effective. Also, he puts forth the matched plan for post--thermal recovery process.
