【摘要】：大港油田棗南東區(qū)塊經(jīng)過長期的注水開發(fā),整體已進(jìn)入高含水期開發(fā)階段。油藏開發(fā)雖然經(jīng)過多次方案調(diào)整,但由于系統(tǒng)整體的調(diào)整方案不到位,加之目的區(qū)塊儲(chǔ)層非均質(zhì)性強(qiáng),儲(chǔ)層巖性細(xì),孔隙結(jié)構(gòu)復(fù)雜,使得地下油水關(guān)系變得非常復(fù)雜,加大了利用測(cè)井資料判別水淹級(jí)別的難度,造成水淹層測(cè)井解釋結(jié)論與生產(chǎn)吻合程度差,不能滿足日益復(fù)雜的油田開發(fā)對(duì)水淹層測(cè)井解釋的要求。因此,論文提出建立一套適合研究區(qū)塊的水淹層測(cè)井解釋方法。論文首先對(duì)棗南區(qū)塊前兩輪的水淹層測(cè)井解釋方法進(jìn)行了調(diào)研,然后分析了儲(chǔ)層水淹后泥質(zhì)含量、電阻率、物性、潤濕性、巖電參數(shù)以及地層水礦化度等儲(chǔ)層參數(shù)的變化特征,為水淹層定性、定量識(shí)別模型的建立奠定了基礎(chǔ)。此外,本文也對(duì)油層水淹后SP自然電位、電阻率以及聲波時(shí)差曲線的測(cè)井響應(yīng)特征進(jìn)行了分析,為水淹層的定性識(shí)別奠定了基礎(chǔ)。在水淹層定性識(shí)別上,本文利用交會(huì)圖法、SP自然電位基線偏移法、井間電阻率對(duì)比法、徑向電阻率比值法、Fisher判別法、多元隸屬函數(shù)判別法以及密度聚類近鄰法等數(shù)學(xué)方法來識(shí)別水淹層,最終通過方法對(duì)比,選擇密度聚類近鄰法作為研究區(qū)塊水淹層定性識(shí)別的方法。在建立儲(chǔ)層參數(shù)模型時(shí),本文首先利用巖心和測(cè)井資料建立了泥質(zhì)含量、粒度中值、孔隙度、滲透率和飽和度等儲(chǔ)層參數(shù)模型,所建立的模型與巖心分析結(jié)果具有較好的吻合性,說明模型精度較高。在水淹層定量識(shí)別上,論文也利用相滲資料、壓汞和核磁共振資料,基于經(jīng)驗(yàn)公式和擬合的方法,建立了束縛水飽和度、殘余油飽和度、油水相對(duì)滲透率、產(chǎn)水率以及驅(qū)油效率等水淹級(jí)別劃分參數(shù)計(jì)算模型,并且建立了適合目的區(qū)塊的水淹級(jí)別劃分標(biāo)準(zhǔn),運(yùn)用該標(biāo)準(zhǔn)對(duì)目的區(qū)塊進(jìn)行處理,應(yīng)用效果較好。
[Abstract]:Through long-term water flooding, Zaonan East Block of Dagang Oilfield has entered the stage of high water cut. Although the reservoir development has been adjusted many times, the whole adjustment scheme of the system is not in place, coupled with the strong heterogeneity of the reservoir in the target block, the fine lithology of the reservoir and the complex pore structure, which make the relationship between underground oil and water become very complex. The difficulty of using logging data to distinguish water flooding level is increased, which results in poor agreement between logging interpretation and production, which can not meet the requirements of increasingly complex oilfield development for logging interpretation of water flooded zone. Therefore, a set of logging interpretation methods suitable for the study block is proposed in this paper. In this paper, the logging interpretation methods of the first two rounds of water-flooded zone in Zaonan block are investigated, and then the variation characteristics of reservoir parameters such as muddy content, resistivity, physical property, wettability, rock electrical parameters and formation water salinity are analyzed. It lays a foundation for the establishment of qualitative and quantitative identification model of waterflooded layer. In addition, the logging response characteristics of SP natural potential, resistivity and sonic moveout curve after flooding are analyzed in this paper, which lays a foundation for qualitative identification of water-flooded zones. In the qualitative identification of water-flooded zones, this paper uses the cross plot method, SP natural potential baseline migration method, cross-well resistivity contrast method, radial resistivity ratio method and Fisher discriminant method. Multiple membership function discrimination and density clustering nearest neighbor method are used to identify waterflooded layer. Finally, density clustering nearest neighbor method is selected as the qualitative identification method of waterflooded zone through comparison of methods. In the process of establishing reservoir parameter model, the reservoir parameter models, such as muddy content, median particle size, porosity, permeability and saturation, are established by using core and logging data. The established model is in good agreement with the core analysis results, which indicates that the model has higher accuracy. Based on empirical formula and fitting method, the irreducible water saturation, residual oil saturation and relative permeability of oil and water are also established by using phase permeation data, mercury injection and nuclear magnetic resonance data. The calculation model of waterflooding classification parameters such as water production rate and oil displacement efficiency is established, and the standard of waterflooding level is established for the target block, which is used to treat the target block, and the application effect is good.
