【摘要】：LG油田開發(fā)的主要目的層為葡萄花油層。但由于該區(qū)油水分布復(fù)雜,油水同層十分發(fā)育(油水同層地質(zhì)儲量占總儲量的67%;統(tǒng)計(jì)區(qū)內(nèi)探評井試油資料,油水同層占試油總層數(shù)的53%),油水層識別難度大,從而影響了射孔方案的編制和儲量的有效有序動用,為此,本文開展了對LG油田復(fù)雜油水識別方法研究,為油田產(chǎn)能建設(shè)提供技術(shù)支持。本文通過測井、錄井、取心、試油等資料,采用趨勢分析法對測井曲線進(jìn)行標(biāo)準(zhǔn)化研究,通過校正后的AC、GR曲線交會圖,確定曲線的合理性,從而建立儲層“四性關(guān)系”,并在“分區(qū)、分段、分類”的基礎(chǔ)上,研究不同類型儲層的流體識別方法,分區(qū)分類建立油水層解釋模型。通過巖電實(shí)驗(yàn),選取適合不同孔隙類型的油水解釋評價參數(shù),分區(qū)研究含水飽和度計(jì)算方法,建立產(chǎn)水率計(jì)算模型,在此基礎(chǔ)上,建立定性與定量相結(jié)合的油水同層細(xì)分模型,還通過分析低阻油層、高阻水層成因,建立低阻油層和高阻水層識別方法。本論文通過對全區(qū)已有的巖心物性分析化驗(yàn)數(shù)據(jù)、重礦物含量及組合關(guān)系、粘土礦物絕對含量及相對含量、粒度分析、壓汞毛管壓力等多項(xiàng)實(shí)測資料的組合和統(tǒng)計(jì),結(jié)合已有的沉積相、構(gòu)造特征,開展LG油田油水層解釋方法的研究,建立精細(xì)的地質(zhì)模型,分區(qū)、分類建立油水層解釋圖版和含水率解釋模型,為LG油田的大面積開發(fā)奠定一定的基礎(chǔ)。
[Abstract]:The main purpose of LG oilfield development in Putaohua formation. But because of the oil-water distribution in this area is very complex, oil-water layer development (oil-water layer geological reserves accounted for 67% of total reserves; statistical area exploration appraisal wells oil test data, test oil and oil-water layer accounted for total number of 53%), the identification difficult large, thus affecting the preparation and reserves perforation design effective and orderly use, therefore, this paper carried on the research of LG oilfield oil identification methods, and provide technical support for oilfield productivity construction. Through well logging, logging, coring, oil testing data, standardization of logging curve by using the trend analysis method. The corrected AC, GR curve intersection diagram, determine the rationality of the curve, so as to establish reservoir "four properties" and "segment in the partition, based on the classification of fluid identification methods of different types of reservoirs, the establishment of oil layer classification To explain the model. Through the rock electric experiment, selecting the suitable water and different pore types interpretation parameters, calculation method of zoning of water saturation, water production rate calculation model is established, based on the model of water to establish qualitative and quantitative with layers, through the analysis of low resistivity reservoir, high resistivity water causes a low resistivity and high resistivity water layer identification method. This paper through the core properties of the existing test data, heavy mineral content and association, granularity analysis of clay mineral content and relative content of mercury, such as hair tube pressure measured data combination and statistics, combining the sedimentary facies, tectonic features. To carry out the Study on the interpretation method of LG oil and water layer, the establishment of a geological model, fine partition, classification established oil layer interpretation chart and moisture interpretation model for LG oilfield development lay a large area The foundation.
