Directed by the advance theories of sequence stratigraphy, reservoir beds sedimentology, seismic stratigraphy and petro - geology, measured by exactitude seismic procession, analysis of seismic facies, analysis of single well lithfacies and sedimentary facies, study of macro and micro character of reservoir and diagenesis, this paper study comprehensively the stratigraphy sequence, the type and distributiong of sedimentary facies, reservoir properties, the diagenesis and the evolution of pores of the 2nd and 3rd parts of pingdiquan formation of permian in wucaiwan - shishugou region in jungan basin. we can optimum seek favourable target area and apply the study results on oil field production in order to solve the difficult questions. we mainly achieve several views as follows : l ) establish the sedimential sequence framework of permian formation in studying area and delimint the jiangjunmiao formation of middle dyas series as lowstand system tract, the lower of the second part to the third part of pingdiquan formation of middle dyas series as transgressive system tract, the upper of the second part to the first part of pingdiquan formation as highstand system tract
以層序地層學、儲層沉積學、地震地層學、石油地質學的先進理論為指導，以地震資料精細目標處理、地震相分析、單井巖相分析、沉積相分析、宏觀和微觀儲層特徵分析及成巖作用研究為手段，對準噶爾盆地東部五彩灣? ?石樹溝地區二疊系平地泉組二、三段的地層層序、沉積相類型及展布、儲層物性特徵、成巖作用及孔隙演化進行綜合研究，優選出有利勘探區帶，並將研究結果應用到生產中，解決生產中的難題，主要取得了以下幾點認識：建立了工區內二疊系沉積層序框架，把中二疊統將軍廟組地層劃為低水位體系域，中二疊統平地泉組二段下部三段地層為水進體系域，二段上部一段地層為高水位體系域。 -
Three sets of source rocks had been formed juring the steady sinking of the basin. the first source rock, being clay and calcium clay stone in tiemulike formation of permian was formed in deep lake environment ; the second source rock, being clay stone in xiaoquangou group of middle to upper triassic was formed in the offshore and the shallow lake environment ; and the third source rock, being coal beds in badaowan formation of lower jurassic was formed in the lake - swamp environment. the first one is the most potential, since it has the biggest thickness, the highest organic matter abundance, high maturity and the highest hydrogen generating capacity
