In this paper , oil reservoir fine description has been applied , and by study of reservoir , structure and fluid features , fluid units have been divided and new geology models have been rebuilt . then logging data have been reinterpreted and reprocessed and numerical modeling results have been used . on base of these work , the residual oil distribution feature and regulation in the fluvial facies sandstone in gudao oil field south region has been scientifically studied 本文主要運(yùn)用油藏精細(xì)描述技術(shù),通過(guò)儲(chǔ)層、構(gòu)造、流體研究,劃分出流體流動(dòng)單元,重建新的地質(zhì)模型,在此基礎(chǔ)上對(duì)測(cè)井資料進(jìn)行了重新解釋和處理,并運(yùn)用數(shù)值模擬研究結(jié)果,對(duì)孤島油田南區(qū)河流相砂巖油藏剩余油分布特征和分布規(guī)律進(jìn)行了科學(xué)研究。
1 . comparing reservoir beds in details step by step , we have divided and compared the deposition time unit in guan 3 - 6 sandstone bed sets , which has been divided into 20 small beds , 30 time units : rebuilding oil sandstone body data table , building graph database , further analyzing the level and section plane configuration and combination pattern of sandstone , and deducing the maze reservoir geology model of river sandstone , are the most important basis for oil reservoir description and residual oil distribution study 1 、采用儲(chǔ)層逐級(jí)細(xì)分對(duì)比方法,對(duì)館3 - 6砂層組進(jìn)行了沉積時(shí)間單元的劃分對(duì)比,共劃分出20個(gè)小層、 30個(gè)時(shí)間單元;重新編制了油砂體數(shù)據(jù)表,建立了圖表數(shù)據(jù)庫(kù),并進(jìn)一步分析了單層砂體平面、剖面形態(tài)以及砂體組合模式,總結(jié)出河道砂體屬迷宮式儲(chǔ)層地質(zhì)模型,這是精細(xì)油藏描述及剩余油分布研究的最重要基礎(chǔ)。
With the development of oil fields , many old reservoirs in the east of china enter the high water - bearing development period . sustaining a high and stable production rate faces severe challenge . the key to preserve oil output in high water cut period is dependent upon the understanding degree to the properties of residual oil distribution . from 1980 ' s , while the study of the reservoir flow unit was proceeded alongside , it has been more widely utilized to characterize reservoir feature and remnant oil distribution . study of reservoir flow unit plays . both theoretically and practically . an important role in recognizing reservoir heterogeneity . performing a high - definition reservoir delineation and understanding the distribution of the remnant oil in the reservoir 隨著油田的不斷開(kāi)發(fā),我國(guó)東部許多老油田已進(jìn)入高含水期開(kāi)采階段,保持油氣產(chǎn)量的穩(wěn)定面臨嚴(yán)竣的挑戰(zhàn),而高含水油田穩(wěn)產(chǎn)的關(guān)鍵取決于對(duì)剩余油分布的認(rèn)識(shí)程度。八十年代以來(lái),隨著對(duì)儲(chǔ)層流動(dòng)單元研究的不斷深入,它越來(lái)越廣泛地被應(yīng)到油藏描述和剩余油研究中來(lái),流動(dòng)單元研究對(duì)于認(rèn)識(shí)儲(chǔ)層的非均質(zhì)性、提高油藏描述精度、搞清剩余油分布具有重要的理論意義和實(shí)際意義。
In this paper , the author explains the cross well technology series that suits for the bohai bay area that combines oilfield production with cross well seismic acquisition , processing and result analysis , therefore , a key technical method was provided for oilfield development in eor and determination of residual oil distribution 本文主要結(jié)合油田的實(shí)際生產(chǎn),從井間地震的野外采集、資料處理、效果分析等方面總結(jié)出一套適合渤海灣地區(qū)的井間地震技術(shù)系列方法,從而為油田開(kāi)發(fā)提高采收率、挖掘剩余油分布方面提供了一項(xiàng)主要的技術(shù)方法。
