【摘要】：基于巖心描述、地化分析及相關(guān)測(cè)井曲線孔滲的實(shí)驗(yàn)數(shù)據(jù),研究了大安油田扶余油層的孔滲發(fā)育特征、儲(chǔ)層含油性的主控因素有哪些等問題,通過劃分含油性級(jí)別和對(duì)其分級(jí)識(shí)別后進(jìn)行分類,以此達(dá)到儲(chǔ)層含油性評(píng)價(jià)的目的。大安油田位于松遼盆地南部中央坳陷區(qū)大安紅崗階地的二級(jí)構(gòu)造帶中,研究區(qū)內(nèi)主要發(fā)育河控三角洲沉積體系,地層變化相對(duì)復(fù)雜,存在超低滲致密砂巖儲(chǔ)層。本文結(jié)合宏觀沉積特征與微觀儲(chǔ)層結(jié)構(gòu)特征,利用實(shí)驗(yàn)手段結(jié)合生產(chǎn)相關(guān)數(shù)據(jù),得出研究區(qū)內(nèi)分流河道微相主要以含油、油浸和油斑為主,河口壩微相為油斑、熒光和不含油,席狀砂微相為油斑和不含油,天然堤微相都不含油,道間薄層砂微相為油斑、熒光和不含油。根據(jù)相關(guān)數(shù)據(jù),建立了含油性與測(cè)井關(guān)系劃分模版,為大安油田扶余油層后續(xù)研究提供參考。
[Abstract]:Based on core description, geochemistry analysis and experimental data of porosity and permeability of logging curve, the characteristics of pore and permeability development of Fuyu reservoir in Da'an oilfield and the main controlling factors of reservoir oil content are studied. In order to achieve the purpose of reservoir oil-bearing evaluation, the oil bearing grade is classified and classified after classification. The Da'an oilfield is located in the secondary structural zone of the Da'an Honggang terrace in the central depression of the southern Songliao Basin. The fluvial delta sedimentary system is mainly developed in the study area, the stratigraphic changes are relatively complex, and there is an ultra-low permeability tight sandstone reservoir. In this paper, combining the macroscopic sedimentary characteristics with the microscopic reservoir structure characteristics, we combine the experimental means with the production data. It is concluded that the microfacies of distributary channel in the study area are mainly oil bearing, oil immersion and oil spots, oil spots in estuaries and dams, oil spots and no oil in sheet sand microfacies, no oil in natural embankment microfacies, and oil spots in thin sand microfacies in interchannel. Based on the relevant data, the relationship between oil bearing and logging is established, which provides a reference for the further study of Fuyu reservoir in Da'an Oilfield.
