【摘要】：利用巖心、薄片、常規(guī)測井、成像測井等資料結(jié)合物性分析等,對鄂爾多斯盆地合水地區(qū)長7致密油巖性巖相等特征進(jìn)行了研究。長7致密油儲層以砂質(zhì)碎屑流、濁流和滑塌成因的砂巖為主,烴源巖以泥巖、油頁巖為主,根據(jù)粒度參數(shù)進(jìn)一步將長7致密油巖性巖相劃分為砂質(zhì)碎屑流細(xì)砂巖相、濁流細(xì)砂巖相、濁流粉砂巖相、滑塌巖相、半深湖—深湖泥巖相以及油頁巖相6類。通過巖心刻度常規(guī)和成像測井,建立了不同巖性巖相的測井識別評價標(biāo)準(zhǔn),并實現(xiàn)了各單井縱向上的巖性巖相的識別和劃分。在此基礎(chǔ)上,進(jìn)一步探討了不同巖性巖相與TOC含量和脆性指數(shù)的關(guān)系。最后結(jié)合試油氣資料和油氣解釋結(jié)論,闡明巖性巖相對致密油儲層物性和含油氣性的定量控制。致密油巖性巖相的研究可為后期成巖相、孔隙結(jié)構(gòu)以及優(yōu)質(zhì)儲集體預(yù)測等奠定基礎(chǔ),為研究區(qū)長7致密油的綜合評價和有利發(fā)育區(qū)帶預(yù)測提供理論指導(dǎo)和技術(shù)支持。
[Abstract]:Using core, thin slice, conventional logging, imaging logging and other data combined with physical properties analysis. The lithofacies and lithofacies of Chang 7 tight oil in Heshui area of Ordos Basin are studied. The reservoir of Chang 7 tight oil is composed of sand clastic flow, turbidite and sloughing sandstone, and source rock is mudstone and oil shale. According to the granularity parameters, the lithofacies of Chang 7 dense oil are further divided into fine sand facies, fine sand facies, siltstone facies and sloughing lithofacies, which are composed of sand clastic flow fine sand facies, turbidite fine sand lithofacies and turbidite siltstone facies. There are 6 types of semi-deep lacustry-deep lake mudstone facies and oil shale facies. Through core calibration routine and imaging logging, the logging identification and evaluation criteria for different lithofacies are established. The recognition and division of lithologic lithofacies in each single well are realized. The relationship between different lithofacies and TOC content and brittleness index is further discussed. Finally, combined with oil and gas test data and hydrocarbon interpretation conclusion. The quantitative control of the physical properties and hydrocarbon bearing properties of the relatively dense oil reservoirs of lithologic rocks is expounded. The study of the lithofacies of dense oil can lay a foundation for the prediction of late diagenesis, pore structure and high quality reservoir. It provides theoretical guidance and technical support for the comprehensive evaluation and the prediction of favorable development zone of zakang 7 dense oil.
