【摘要】：本文以鄂爾多斯盆地伊陜斜坡北緣的蘇25區(qū)塊盒8段和山1段地層為研究對象,運(yùn)用沉積學(xué)、石油地質(zhì)學(xué)理論及科學(xué)研究方法,在對研究區(qū)取得的測井、錄井、鉆井取心及分析化驗(yàn)資料等深入分析的基礎(chǔ)上,對蘇25區(qū)塊盒8段和山1段沉積特征進(jìn)行了深入分析,取得了以下成果與認(rèn)識：1.蘇25區(qū)塊的目的層段盒8段與山1段的巖石類型由于沉積相的不同而有所差異：在盒8段,巖石類型按觀測到的巖石碎屑含量從高到低依次排列,分別為巖屑石英砂巖、石英砂巖以及巖屑砂巖；山1段則仍以巖屑石英砂巖最為發(fā)育,其次為巖屑砂巖,石英砂巖發(fā)育最少。2.研究區(qū)盒8下段為辮狀河沉積,主要發(fā)育心灘和洪泛平原；盒8上段與山1段為曲流河沉積,主要發(fā)育河道和河漫沉積。3.蘇25區(qū)塊氣藏類型為低孔低滲的巖性氣藏,具有疊置的特點(diǎn)。4.蘇25區(qū)的沉積相對儲(chǔ)層展布具有控制作用,儲(chǔ)層展布與含氣層分布正相關(guān),所以本次研究認(rèn)為沉積相對氣藏的分布有一定的間接控制作用。
[Abstract]:In this paper, the stratigraphy of Bo8 and Shan 1 member of Su25 block in the northern margin of Yi-shan slope in Ordos Basin is taken as the research object. The logging and logging obtained in the study area are carried out by using the theory of sedimentology, petroleum geology and scientific research methods.On the basis of deep analysis of drilling coring and analysis of laboratory data, the sedimentary characteristics of Bo8 member and Shan1 member in Su25 block are analyzed, and the following results and understanding are obtained.The rock types of Bo8 member and Shan1 member in Su25 block are different because of the different sedimentary facies. The rock types are arranged according to the observed rock clastic content from high to low in order of lithic quartz sandstone, respectively.Quartz sandstone and lithic sandstone are the most developed in Shan 1, followed by lithic sandstone, quartz sandstone is the least developed.In the study area, the lower member of Bo8 is braided river deposition, which is mainly developed in Xintan and flood plain, and the upper member of Bo8 and Shan 1 is meandering river deposition, which mainly develops channel and river diffuse sedimentation .3.The type of gas reservoir in Su25 block is lithologic gas reservoir with low porosity and low permeability, which has the characteristics of superposition.The distribution of sedimentary relative reservoir in Su25 area is controlled, and the distribution of reservoir is positively related to the distribution of gas-bearing reservoir, so it is considered that the distribution of sedimentary relative gas reservoir has some indirect control function.
