【摘要】:遼河坳陷西部凹陷南部興隆臺一馬圈子潛山構(gòu)造帶北部,具有十分優(yōu)越的油氣成藏條件。2006年上報含油面積3.46km2,原油地質(zhì)儲量2094.8×104 t。該油藏具有世界上己知的最厚的油層、復(fù)雜的地質(zhì)構(gòu)造和風(fēng)險較高的地面條件,通過對興馬潛山帶南部中生界儲層的預(yù)測,可進(jìn)一步認(rèn)清研究區(qū)油藏地質(zhì)及其在開發(fā)過程中的特點(diǎn),利用反演技術(shù)對儲層進(jìn)行預(yù)測,能夠提高對研究區(qū)儲層的進(jìn)一步認(rèn)識,并對同類油藏開發(fā)具有現(xiàn)實的指導(dǎo)意義。本文旨在利用錄井取心、測井資料等技術(shù),從巖石物理研究入手,開展了本區(qū)地層巖性重新認(rèn)識、地層劃與對比,從而對區(qū)域地質(zhì)背景進(jìn)行新的認(rèn)識;并利用三維地震技術(shù),以及Landmark工作站解釋系統(tǒng),TDQ技術(shù)成圖等對研究區(qū)構(gòu)造重新認(rèn)識的同時并做出構(gòu)造解釋;結(jié)合巖心物性分析以及儲層四性評價對研究區(qū)中生界儲層進(jìn)行了評價;以及通過多井約束三維稀疏脈沖反演技術(shù)以及JASON軟件對儲層進(jìn)行反演分析,一方面通過三維地震資料波阻抗反演對空白區(qū)的儲層橫向展布進(jìn)行預(yù)測,另一方面對已鉆井的井資料進(jìn)行儲層對比統(tǒng)計分析,以實現(xiàn)儲層預(yù)測。研究區(qū)中生界地層屬于殘留沉積,儲層以火山角礫巖為主,中生界地層波阻抗為一套整體偏中高阻阻抗。在研究區(qū)中部中生界地層比較發(fā)育的部位反演效果比較好,對有利儲層的發(fā)現(xiàn)有一定的指導(dǎo)意義。
[Abstract]:In the north of Xinglongtai Mahuan buried hill structural belt in the south of the western depression of Liaohe depression, it has excellent oil and gas accumulation conditions. The oil area of 3.46 km ~ 2 was reported in 2006, and the geological reserves of crude oil were 2094.8 脳 10 ~ 4 t. The reservoir has the thickest reservoir known in the world, complex geological structure and high risk surface conditions, through the prediction of Mesozoic reservoirs in the southern Xingma buried hill belt. The reservoir geology and its characteristics in the development process of the study area can be further recognized, and the inversion technique can be used to predict the reservoir, which can improve the further understanding of the reservoir in the study area and have practical guiding significance for the development of the same kind of reservoir. The purpose of this paper is to make use of the techniques of logging coring and logging data, starting with the study of rock physics, to carry out a new understanding of the lithology, stratigraphic division and correlation of the strata in this area, and to make a new understanding of the regional geological background, and to make use of the three-dimensional seismic technology. The Landmark workstation interpretation system is used to map the structure of the study area, and the structure interpretation is made at the same time, and the Mesozoic reservoir in the study area is evaluated by combining the core physical property analysis and reservoir evaluation. And through the multi-well constrained 3D sparse pulse inversion technology and JASON software to carry on the inversion analysis to the reservoir, on the one hand, through the three-dimensional seismic data wave impedance inversion to carry on the prediction to the reservoir horizontal distribution in the blank area, On the other hand, the well data are analyzed and compared to realize reservoir prediction. The Mesozoic strata in the study area belong to residual deposits, the reservoir is mainly volcanic breccia, and the Mesozoic formation wave impedance is a set of integral partial middle and high impedance. The inversion effect of Mesozoic strata developed in the middle of the study area is good, which has certain guiding significance for the discovery of favorable reservoir.
