【摘要】：我國復(fù)雜斷塊油藏分布眾多,與常規(guī)油藏相比,由于復(fù)雜斷塊的地質(zhì)構(gòu)造及油水關(guān)系的復(fù)雜性,開采難度較大,因此針對復(fù)雜斷塊的地質(zhì)特征及開發(fā)特征,綜合分析各種因素對斷塊油藏開發(fā)規(guī)律的影響,研究剩余油在復(fù)雜斷塊中的分布特點,對改善復(fù)雜斷塊油藏開發(fā)效果以及提高復(fù)雜斷塊油藏的采收率具有重要的意義。本文以L17斷塊油藏為研究對象,開展了對復(fù)雜斷塊油藏開發(fā)規(guī)律及剩余油分布的研究。本文主要從產(chǎn)能遞減規(guī)律及水驅(qū)開發(fā)規(guī)律兩個方面進行油藏開發(fā)規(guī)律研究,通過對實際油藏開發(fā)資料的統(tǒng)計分析,以現(xiàn)代油藏工程理論為研究方法,分析了L17斷塊的產(chǎn)能特征,研究了產(chǎn)能遞減規(guī)律,對影響產(chǎn)能遞減的因素進行了系統(tǒng)性的分析,并提出了減緩產(chǎn)能遞減的有效途徑,對單井的增產(chǎn)措施進行了分析及評價;分析了L17斷塊含水率特征,利用經(jīng)驗公式法、童式圖版法、水驅(qū)特征曲線法、產(chǎn)量遞減法分別對采收率進行了預(yù)測,綜合得到L17斷塊的水驅(qū)目標(biāo)采收率,通過分析研究L17斷塊油藏的存水率、水驅(qū)儲量控制程度、水驅(qū)儲量動用程度等注水開發(fā)指標(biāo),對L17斷塊的水驅(qū)開發(fā)效果進行了評價。綜合L17斷塊的儲層物性特征、沉積特征、構(gòu)造特征及開發(fā)特征等,對L17斷塊的剩余油分布模式及控制因素進行了定性分析研究,利用剩余油分布模糊綜合評價理論對L17斷塊剩余油分布進行了定量評價及預(yù)測。
[Abstract]:There are many complex fault block reservoirs in China. Compared with conventional reservoirs, it is difficult to exploit because of the complexity of geological structure and oil-water relationship of complex fault blocks, so the geological characteristics and development characteristics of complex fault blocks are analyzed. Synthetically analyzing the influence of various factors on the development law of fault-block reservoir and studying the distribution characteristics of residual oil in complex fault-block are of great significance for improving the development effect of complex fault-block reservoir and enhancing the recovery factor of complex fault-block reservoir. Taking L17 fault block reservoir as the research object, the development law and remaining oil distribution of complex fault block reservoir are studied in this paper. In this paper, reservoir development law is mainly studied from two aspects: productivity decline law and water drive development law. Through statistical analysis of actual reservoir development data and modern reservoir engineering theory, the productivity characteristics of L17 fault block are analyzed. In this paper, the law of productivity decline is studied, the factors influencing productivity decline are systematically analyzed, and the effective ways to slow down productivity decline are put forward, the measures of increasing production of single well are analyzed and evaluated, and the water cut characteristics of L17 fault block are analyzed. By using empirical formula method, Tong type chart method, water drive characteristic curve method and production decline method, respectively, the recovery factor of L17 fault block is forecasted, and the water storage rate of L17 fault block reservoir is analyzed and studied. The water flooding development effect of L17 fault block is evaluated by water drive reserve control degree, water drive reserve production degree and so on. Based on the reservoir physical, sedimentary, structural and development characteristics of L17 fault block, the distribution pattern and controlling factors of residual oil in L17 fault block are qualitatively analyzed and studied. The residual oil distribution of L17 fault block is quantitatively evaluated and predicted by using the fuzzy comprehensive evaluation theory of residual oil distribution.
