摘要
为研究渤海S油田注聚合物阶段油井合理井底压力界限,利用油藏工程方法及数值模拟技术,推导了聚合物驱受效井合理井底压力界限的计算公式,并利用现场数据进行验证。研究结果表明,对于反九点井网条件下的聚合物驱受效井,其合理井底压力界限主要受地层压力、水驱阶段井底压力、注聚合物时机、含水率的影响。井底压力位于合理压力界限内的油井,聚合物驱效果较好。该研究成果为油田提高聚合物驱效果,扩大注聚合物区块提供了理论依据。
Reservoir engineering and numerical simulation are used to research the reasonable bottom -hole pressure boundaries of oil wells during polymer flooding in Bohai S Oilfield. A formula to calculate the reasmabh hole pressure boundaries ot polymer flooding response wells is derived and verilied by fieht data. llesearch inicales that the reasonable bottom-hole pressut bomldary of polymer oding response wells in inverted nie-spot pattern is mainly dependent tinmarion pressure, bom-hole pressure luring waterooding, plymer inje（tion tinting and watereut. A betler polymer flooding perlrmanee ean be gained for the well with reasonable pressure boundary. This research could provide a theoretical reference for the enhancement and popularizatinn of polymer flooding.
