【摘要】：本文以板塊構(gòu)造理論為基礎(chǔ),以含油氣盆地整體、動(dòng)態(tài)、綜合分析研究為原則,在綜合分析前人研究成果基礎(chǔ)上,分析處理了區(qū)內(nèi)600余口探井資料,對(duì)奧陶系馬家溝組古今構(gòu)造特征及構(gòu)造演化史進(jìn)行了研究,從構(gòu)造演化的角度剖析烴源巖、儲(chǔ)集層的分布及演化,圈閉的類型及形態(tài)以及運(yùn)移的路徑及方式等,進(jìn)而總結(jié)分析構(gòu)造演化對(duì)天然氣成藏的控制作用。通過研究有以下成果及認(rèn)識(shí):石炭系沉積前,盆地整體呈現(xiàn)西高東低的構(gòu)造形態(tài),近古隆起區(qū)域馬家溝組中組合缺失,古隆起東側(cè)自西向東地層逐漸增厚,盆地中部顯示為隆凹相間的構(gòu)造格局;這種構(gòu)造格局一直延續(xù)到二疊紀(jì)末期。三疊紀(jì)時(shí),受印支運(yùn)動(dòng)影響,盆地內(nèi)部北東向展布的隆凹相間格局完全消失,轉(zhuǎn)而在研究區(qū)形成西、北、東三面相對(duì)抬升隆起,盆地內(nèi)部形成向西南開口的凹陷,馬五5底面最深處在延安一帶。侏羅紀(jì),主要表現(xiàn)為東西分異、其次為南北差異,從而形成了東高西低、北高南低的構(gòu)造面貌,盆地東部為相對(duì)較陡的斜坡,中西部為為凹陷。早白堊末期,盆地總體表現(xiàn)為東高西低、北高南低的面貌,但此時(shí)的斜坡和凹陷都變得較為寬緩,凹陷范圍也變小,盆地整體面貌與現(xiàn)今相似。早白堊世末燕山晚期運(yùn)動(dòng)后,盆地東部抬升,剝蝕部分白堊紀(jì)、侏羅紀(jì)及三疊紀(jì)地層,并逐步形成現(xiàn)今地層?xùn)|高西低,構(gòu)造平緩的斜坡構(gòu)造形態(tài)。構(gòu)造的演化對(duì)氣藏的分布具有一定的控制作用,主要通過控制氣源條件、儲(chǔ)集層特征以及圈閉形成和運(yùn)移路徑來實(shí)現(xiàn)。加里東運(yùn)動(dòng)使馬家溝組地層隆起剝蝕,白云巖儲(chǔ)集層發(fā)育順層溶蝕作用,形成較長(zhǎng)距離的溶蝕孔洞縫,為天然氣供了良好的儲(chǔ)集空間和運(yùn)移通道;晚石炭世鄂爾多斯盆地整體沉降,接受上古生界沉積,中組合地層得以與上古生界煤系烴源巖直接接觸,形成良好的源儲(chǔ)配置關(guān)系;早白堊世沉積期,烴源巖達(dá)到生烴高峰期,燕山運(yùn)動(dòng)造成盆地反轉(zhuǎn),源儲(chǔ)接觸關(guān)系發(fā)生變化,由源上儲(chǔ)下型變?yōu)樵聪聝?chǔ)上型,天然氣沿著溶蝕孔洞縫與晶間孔等形成較長(zhǎng)距離的運(yùn)移通道,在東側(cè)上傾方向的巖性(相)變化處聚集成藏。
[Abstract]:This paper is based on the theory of plate tectonics in petroliferous basin, the overall dynamic and comprehensive analysis of the principle, based on the comprehensive analysis of previous research results, analysis and processing in the area of more than 600 wells data of Ordovician Majiagou Formation in ancient tectonic features and tectonic evolution history was studied, analysis of distribution and evolution of hydrocarbon source rock, reservoir in terms of tectonic evolution, trap type and shape as well as the migration path and methods, and summarizes the evolution analysis of control effect on natural gas reservoir structure. The study has the following results and understanding: the Carboniferous Sedimentary Basin, overall structure from west to East, near the ancient uplift area of Majiagou Formation in the absence of the combination, the paleo uplift gradually thickened from west to east east formation, central basin shows tectonic pattern and tectonic uplift and sag; this pattern has been extended to the at the end of the permian. During the Triassic, by the influence of Indosinian movement, the interphase pattern between the East and the north in the basin disappeared completely. Instead, it formed a relative uplift in the west, North and East three sides in the study area, and formed a depression opening to the southwest in the basin. The deepest part of Ma five 5 bottom was in the Yanan area. The Jurassic is mainly composed of East-West differentiation, followed by North-South differences, thus forming a structural feature of the East, the west, the north and the south. The eastern part of the basin is a relatively steep slope, and the Midwest is a depression. At the end of Early Cretaceous, the basin was characterized by the East, the west, the north and the south, but the slope and sag became wider and slower, and the range of the sag was also smaller. The overall appearance of the basin was similar to that of today. After the late Cretaceous movement in the late Yanshan, the eastern part of the basin was uplifted and denuded by some Cretaceous, Jurassic and Triassic strata, and gradually formed the slope structure form of the east to the west, and the structure to be gentle. The evolution of structure plays a certain role in controlling the distribution of gas reservoirs, mainly through controlling gas source conditions, reservoir characteristics and trap formation and migration path. The Caledonian movement in Majiagou Formation of uplift and denudation, dolomite reservoir bedding dissolution layer development, formation of pores long distance seam, natural gas supply good reservoir space and migration channel; overall settlement of Late Carboniferous Erdos Upper Paleozoic sedimentary basin, accept, in combination with the formation of Upper Paleozoic world coal source rocks in direct contact, the formation of source and reservoir configuration relationships; Early Cretaceous sedimentary period, source rocks reached peak hydrocarbon generation, caused by the movement of Yanshan basin inversion, reservoir contact relationship changes from the source storage type into a source of natural gas along the reservoir, karst cave formation migration long distance channel and intergranular holes, on the east side of the slope lithology (facies) change accumulation.
