摘要(Abstract)：
利用水平井挖潜厚油层的剩余油,目前对大庆老区还属于一种新技术,针对老区高含水后期独具的地质和开发特点,提出了老区水平井地质设计的程序和方法,研究了老区水平井地质设计中储层描述和剩余油分析方法,论述了高含水多层油藏水平井产能预测和经济评价的方法。在此基础上,示意出一次着陆的水平井轨迹,列举了地质设计所需的基本参数,编制了水平井地质设计方案。建议大庆老区应该加快水平井配套技术研究,开展厚油层顶部和断层边部厚油层剩余油挖潜的水平井矿场试验,同时把水平井技术应用到大庆老区工业化推广的三次采油中。
It is thought as a new technology in Daqing to apply horizontal wells to tap the potential of remaining oil in thick pay zones of the mature oilfield in Daqing. Aiming at the unique geological and developing characteristic at the late stage of water cut, the procedures and method of geological design of horizontal wells are worked out after comprehensive correlation and analysis of the res-ervoir in the mature oilfield in Daqing. We elucidate the method of productivity forecasting and economical evaluation of multi-layer reservoir of high water cut. The horizontal section trajectory is sketched and the essential parameters of geological design are enu-merated. The geological project is worked out to tap the potential of remaining oil near faults resulting from incomplete injection/pro-duction.
