Based on the consulting a large number of domestic and international data, the main task, research content, and respective technical methods of oil / gas reservoir description at various stages are summarized in this paper. At the same time as the final results of reservoir description, reservoir geological modeling is a technology that, developed in recent years, quantitatively describes and depicts oil/gas reservoirs. Proceeding from the basic theory of the reservoir modeling , on the basis of a brief introduction to the type of reservoir modeling, several known reservoirmodeling techniques and methods at home and abroad, and their adaptability of various methods are mainly discussed in the paper. Detailed steps of reservoir modeling were enumerated in the paper, and the field of application and effectiveness of reservoir modeling are briefly reviewed. This paper has important significance for a prehensive understanding of the content, methods, theoretical basis, and implementation steps of researches on the fine description of reservoirs and reservoir modeling.前言一般認(rèn)為精細(xì)油藏描述是指油田進(jìn)入高含水期和特高含水期后、對油田挖潛和提高采收率,以搞清剩余油分布特征、規(guī)律及其控制因素為目標(biāo)所進(jìn)行的油藏多學(xué)科綜合研究 [1]。其主要目標(biāo)是建立油藏預(yù)測地質(zhì)模型 [23]。它綜合利用各種地質(zhì)、地震、測井和動(dòng)態(tài)數(shù)據(jù),并用地質(zhì)統(tǒng)計(jì)學(xué)的方法對各種儲(chǔ)層參數(shù)進(jìn)行井間預(yù)測,建立定量精確的三維可視化儲(chǔ)層模型。精細(xì)的儲(chǔ)層地質(zhì)模型是油藏綜合評價(jià)、油藏?cái)?shù)值模擬的基礎(chǔ)。目錄第一章

精細(xì)油藏描述精細(xì)油藏描述是全球油氣開發(fā)領(lǐng)域中的一項(xiàng)關(guān)鍵技術(shù)，自 20 世紀(jì) 80 年代以來，集地質(zhì)、地球物理和油藏工程等多學(xué)科、多專業(yè)力量綜合攻關(guān)，取得了突破的進(jìn)展。20 世紀(jì) 80 年代以來，世界上油藏描述的動(dòng)向可以用“精細(xì)油藏描述”來形象化地概括。我國的油田開發(fā)形勢和世界主要產(chǎn)油國完全相似，進(jìn)一步挖掘已開發(fā)油田潛力，提高采收率，是當(dāng)前的重要內(nèi)容。一個(gè)油田從發(fā)現(xiàn)到廢棄，油田開發(fā)工作要經(jīng)歷認(rèn)識(shí)、實(shí)踐、再認(rèn)識(shí)、在實(shí)踐的多次反復(fù)。由于每個(gè)階段具有的地質(zhì)資料基礎(chǔ)不同，要完成的開發(fā)地質(zhì)任務(wù)也不同，因而在儲(chǔ)層評價(jià)的重點(diǎn)內(nèi)容也有差異，所要達(dá)到的目標(biāo)也就不一樣。一般來說油田發(fā)現(xiàn)后，可分為油藏評價(jià)階段、開發(fā)初期階段和開發(fā)中后期階段，三個(gè)階段對應(yīng)的油藏描述任務(wù)和目標(biāo)各不相同。進(jìn)行動(dòng)態(tài)監(jiān)測，開發(fā)分析；編制有關(guān)層系井網(wǎng)等綜合調(diào)整方案，并組織實(shí)施落實(shí)地質(zhì)儲(chǔ)量及可采儲(chǔ)量；確定構(gòu)造形態(tài)及油氣水分布；全油田小層劃分與對比；搞清油氣富集分布規(guī)律；建立儲(chǔ)層靜態(tài)模型以鉆井資料為主結(jié)合三維地震資料為基礎(chǔ)的構(gòu)造
