摘要: 以国内FY油层为研究对象，将数值模拟技术与改进后相渗曲线相结合，重点对产液量、井距、裂缝导流能力、井型等关键开发因素开展了系统分析与评价。为该油藏低矿化度水驱的实施预测提供了理论参考。研究结果表明，低矿化度水驱相较常规水驱可获得更高的采出程度以及相较低的最终含水率，产液量为140 m3/day，注采井距100 m，水平井压裂技术结合低矿化度水驱时可获得较高的采出程度和较好的经济效益，裂缝导流能力对油藏采出程度影响较小。
Abstract: Taking domestic FY oil reservoir as the research object, the key development factors such as fluid production, well spacing, fracture conductivity and well type were systematically analyzed and evaluated by combining numerical simulation technology with improved phase permeability curve. It provides a theoretical reference for the prediction of low salinity water flooding in this reservoir. The research results show that compared with conventional water flooding low salinity water flooding can obtain higher recovery degree and compared with the low final water cut, the liquid producing capacity for 140 m3/day, injection-production well spacing is 100 m, when the horizontal well fracturing technology in combination with low salinity water flooding can obtain high recovery degree and good economic benefit, fracture diverting capacity less influence on recovery degree of the reservoir.
