断块油气田2023年1月0引言目前众多学者从水槽实验、野外露头、现代沉积及地下储层等不同角度,对储层构型模式及表征方法进行了研究,特别是针对以曲流河储层为代表的河流相储层取得了丰硕的研究成果[1 ̄2]。周银邦等[3]对曲流河点坝平面分布模式进行了总结,简单曲流河发育单一点坝,呈串珠状,废弃河道在平面上发育较少,建模较收稿日期:2022 ̄06 ̄10;改回日期:2022 ̄11 ̄15。第一作者:郑昕,男,1981年生,高级工程师,现主要从事油田开发地质及提高采收率研究与管理工作。E-mail:508073652@qq.com。通信作者:田媛,女,1990年生,助理研究员,硕士,现主要从事地震地质综合研究工作。E-mail:tianyuan903.slyt@sinopec.com。引用格式:郑昕,束青林,苏朝光,等.基于模拟退火的曲流河复合点坝建模新方法[J].断块油气田,2023,30(1):114 ̄119,135.ZHENGXin,SHUQinglin,SUChaoguang,etal.Anewmodelingmethodofmeanderingrivercomplexpointbarsbasedonsimulatedannealing[J].Fault-BlockOil&GasField,2023,30(1):114 ̄119,135.AnewmodelingmethodofmeanderingrivercomplexpointbarsbasedonsimulatedannealingZHENGXin1,SHUQinglin1,SUChaoguang2,WUShenghe3,JIANGXiaowei1,TIANYuan2,YUEDali3(1.HydrocarbonDevelopmentandManagementCentre,ShengliOilfieldCompany,SINOPEC,Dongying257001,China;2.GeophysicalResearchInstitute,ShengliOilfieldCompany,SINOPEC,Dongying257022,China;3.CollegeofGeosciences,ChinaUniversityofPetroleum,Beijing100083,China)Abstract:Anewmethodformodelingameanderingrivercomplexpointbarsbasedonsimulatedannealingisproposedinthispaper.Comparedwithtarget-basedanddepositionprocess-basedmethods,thenewmethodismoreflexibleandeasiertocondition.Comparedwithtwo-pointstatisticalmodelingandmulti-pointstatisticalmodeling,thenewmethodcanbetterreproducecomplexchannelcharacteristics.Comparedwiththedeterministicmodelingmethodbasedonfinearchitectureanatomy,thenewmethodissuitableforthesparsewellsituation.Thenewmethodestablisheseighttypesofsinglepointbarmodelsbyrandomlyselectingsinglepointbarfromthebead-likepointbarsbygraduallysimulatingthecenterlineoftheriverchannel,theactivechannel,andthebead-likepointbars,andusestheseeighttypesofsing...
