【摘要】：研究區(qū)長9儲層位于鄂爾多斯盆地JY地區(qū)東部,屬于低孔低滲儲層,具有較大的開發(fā)潛力。該地區(qū)油藏的形成很大程度上受沉積環(huán)境的影響,而油藏的開發(fā)又受到儲層非均質性的控制。因此為了能夠制定合理的開發(fā)政策,對長9油藏進行合理而高效的開發(fā),對長9儲層展開了沉積相與儲層非均質性的研究。本文首先應用層序地層學等原理對長9儲層進行精細的地層劃分與對比,建立全區(qū)的等時地層骨架;在此基礎上,以JY地區(qū)長9地層的區(qū)域沉積背景為依據,結合沉積相的各種沉積標志及測井相標志對該地區(qū)展開沉積環(huán)境的識別,并繪制長9各小層的沉積微相平面圖來研究各沉積微相在研究區(qū)的分布特征;通過在各沉積微相區(qū)域進行取芯,從微觀方向具體分析了長9儲層的巖石學特征及孔隙結構特征,利用陰極發(fā)光、掃描電鏡以及鑄體薄片的分析方法對研究區(qū)成巖相類型進行識別,并繪制了各種成巖相在平面上的分布圖,以研究長9儲層的成巖作用;儲層非均質性是受沉積作用和成巖作用的雙重控制的,結合長9沉積相與儲層特征的研究成果,利用長9各小層的滲透率數據、含油性數據、層間隔層厚度及層內夾層厚度等數據,計算各種儲層非均質參數,繪制各類能夠反映儲層差異性質的圖件,對長9各小層展開層間、平面及層內非均質性的研究。
[Abstract]:Chang 9 reservoir is located in the eastern JY area Ordos basin belongs to low porosity and low permeability reservoir, has great potential for development. The formation is largely influenced by the sedimentary environment in the area of the reservoir, and the reservoir development is controlled by reservoir heterogeneity. So in order to develop a reasonable development policy, development reasonable and efficient for the long 9 reservoir of Chang 9 reservoir of reservoir heterogeneity of the sedimentary facies and reservoir. Firstly, application of sequence stratigraphy principle of fine stratigraphic classification and correlation of Chang 9 reservoir, stratigraphic framework is established in the region; on this basis, the regional sedimentary background with JY area 9 on the basis of the formation of various sedimentary facies, sedimentary and logging facies identification on sedimentary environment of the area, and draw the 9 layer of the small sedimentary microfacies of the sedimentary microfacies in the study The distribution characteristics of the core area; through the sedimentary facies area, analyzes the petrological characteristics and pore structure characteristics of Chang 9 reservoir from the microcosmic direction, using cathodoluminescence, scanning electron microscopy and analysis method of casting slice identification of diagenetic facies in the study area, and all kinds of diagenetic facies in the plane the distribution maps of the diagenesis of Chang 9 reservoir; reservoir heterogeneity is controlled by both sedimentation and diagenesis, with 9 sedimentary facies and reservoir characteristics of the research results, using 9 permeability data of each small layer, interlayer thickness and oil content data the interlayer thickness data layer, calculating the reservoir parameter, drawing all kinds of maps can reflect the differences of reservoir properties, 9 layers of expansion between layers, on the plane and in layer heterogeneity.
