From sedimentology symbol such as rock assembled, sediment gradus, sandstone grading analysis, protogene sedimentary structure, ichnofossile and logging facies etc and palaeoenvironment background, it is confirmed that shen84 - an12block s34 segment is braid river delta system, not fan delta system ( abrupt slope ). then it can be more partition as braid river delta plain sedimentary assembled, delta front sedimentary assembled and prodelta sedimentary assembled on core and log assembled. and delta plain sedimentary assembled can be identified four microfacies : braided distributary channel, crevasse splay, overbank deposits and interdistributary bay
沉積微相研究是儲層非均質性研究的基礎，研究區有豐富的巖芯資料和測井資料，通過巖石組合、沉積韻律，砂巖粒度分析、沉積構造、古生物遺跡和測井相等沉積學標志，結合古環境背景，確定沈84 ?安12塊s _ 3 ~ 4段為辮狀河三角洲體系，而不是前人所認為的扇三角洲（陡坡型）體系，在巖芯和測井組合上可進一步劃分為辮狀河三角洲平原沉積組合、三角洲前緣沉積組合和前三角洲沉積組合，其中三角洲平原沉積組合又可識別出辮狀分流河道、決口扇、分流河道邊部和分流間灣四種微相類型；三角洲前緣沉積組合識別出水下分流河道、水下分流河道邊部和分流河口壩三種微相。The basic principle and method of 3d stochastic modeling of sedimentary microfacies are discussed according to geological and acoustic impedance data of well - logging constrained seismic inversion, and a case study according to stochastic modeling of fluvial facies reservoir of the minghuazhen formation of neocene in a certain block of bohai bay basin is used to show the general process of this research
