【摘要】：本文研究層段為陜北富縣地區(qū)奧陶系馬家溝組馬五4?馬六段,儲層的非均質(zhì)性很強,己成為影響勘探和生產(chǎn)的主要地質(zhì)因素。本次以野外露頭剖面、巖心觀察為基礎(chǔ),結(jié)合鉆井、錄井資料,以標志層為等時面,沉積旋回控制與電測曲線特征結(jié)合,對馬五廣馬六段進行了地層劃分與對比。運用薄片鑒定、陰極發(fā)光、掃描電鏡、電子探針、微量元素等實驗手段,總結(jié)了研究區(qū)的巖石學(xué)特征、物性特征、成巖作用、孔隙類型及結(jié)構(gòu)特征,進行了儲層微觀和宏觀非均質(zhì)性評價及控制因素分析。研究表明,研宄區(qū)馬家溝組的馬五4-馬五3地層保存較為完整,馬五2-馬六段剝蝕嚴重僅中部的FG2井、東北部的XF4井周邊局部保存哥A段:儲集層石石以角碌z?石、砂礫屑云巖、細晶-泥晶云巖等白云巖為主;儲集空間以晶間孔、晶間溶孔、膏模孔為主,馬五!亞段溶孔發(fā)育:將鄂爾多斯盆地馬家溝組孔隙結(jié)構(gòu)劃分為14小類,并建立了微觀非均質(zhì)性評價參數(shù)FJZ?本區(qū)以中孔細喉單峰和多峰型孔隙結(jié)構(gòu)為主,微觀非均質(zhì)性中等較強;目的層段的儲層突進系數(shù)、變異系數(shù)和連通性等參數(shù)均表明其層內(nèi)、層間和平面具極強的非均質(zhì)性;成巖和構(gòu)造作用是影響儲層非均質(zhì)性的主要作用。
[Abstract]:The study layer in this paper is Mawuang4 of Ordovician Majiagou formation in Fuxian area of northern Shaanxi. The reservoir heterogeneity is very strong and has become the main geological factor affecting exploration and production. On the basis of outcrop profile and core observation, combined with drilling and logging data, taking indicator layer as isochronous plane, combining sedimentary cycle control with characteristics of electric logging curve, stratigraphic division and correlation of the sixth member of Mawuguangma formation are carried out. The petrological characteristics, physical properties, diagenesis, pore types and structural characteristics of the study area were summarized by means of thin plate identification, cathodic luminescence, scanning electron microscope, electron probe and trace elements. Reservoir microcosmic and macroscopic heterogeneity evaluation and control factor analysis were carried out. The results show that the Mawu4-Ma 53 formation of Majiagou formation in the study area is relatively intact, and the denudation of Ma Wu 2-Ma 6 formation is serious only in the central part of FG2 well, and the part of XF4 well in the northeast preserves GE A member: reservoir stone and stone are preserved in Jiao Lu zh? Stone, gravel dolomite, fine crystal-mudstone dolomite and other dolomite; storage space to intergranular pore, intergranular solution pore, mold hole, Ma Wu! The pore structure of Majiagou formation in Ordos Basin is divided into 14 subgroups, and the microcosmic heterogeneity evaluation parameter FJZ? In this area, the pore structure is dominated by single peak and multi-peak pore structure with medium microcosmic heterogeneity, and the reservoir penetration coefficient, variation coefficient and connectivity of the target section all indicate the heterogeneity of the interlayer and interlayer peace mask. Diagenesis and tectonism are the main factors affecting reservoir heterogeneity.
