【摘要】：對于油藏分布規(guī)律復(fù)雜的古龍油田而言,準確的預(yù)測油田的油水的分布情況,是保證油田穩(wěn)定產(chǎn)量、提高采收率的核心問題。受巖性和構(gòu)造雙重影響,工區(qū)油水分布呈現(xiàn)“油水同層、上油下水、上水下油、油水層互間”等特征,聯(lián)合各種手段刻畫微幅度構(gòu)造,進行沉積微相、油氣成藏條件等研究,是提高古龍油田葡萄花油層油藏的油水分布規(guī)律認識精度,發(fā)現(xiàn)有利區(qū)塊及布置有利井位的關(guān)鍵。研究區(qū)主要為巖性油藏,其次為構(gòu)造-巖性復(fù)合油藏,含油層位主要為葡萄花一段,其巖性在縱、橫向上變化快,油層分布在空間上不穩(wěn)定。在古龍油田的不斷勘探開發(fā)過程中,逐漸暴露出該區(qū)的砂體沉積和油水關(guān)系十分復(fù)雜,在原有探明儲量基礎(chǔ)上直接進行開發(fā)風(fēng)險性極大,急需準確認識該區(qū)塊小層砂體分布、儲層物性變化、油水分布情況。本論文以古龍油田葡萄花油層為重點研究區(qū),開展油藏的井震聯(lián)合刻畫方法研究,在測井資料標準化、井震聯(lián)合地質(zhì)層位標定基礎(chǔ)上,通過高分辨率層序地層劃分與對比、多方法刻畫微幅度構(gòu)造、分層分手段刻畫不同規(guī)模河道砂體,分層分手段研究油水分布及油藏類型,確定古龍油田葡萄花油層內(nèi)微構(gòu)造,合理、準確地搞清了砂體展布特征和分布規(guī)律,精細研究成藏主控因素對油水分布的影響,形成古龍油田葡萄花油層精細地質(zhì)研究流程,有效指導(dǎo)有利區(qū)塊的確定及有利井部署。取得的主要成果如下：1.利用錄井、測井、地震等信息,開展葡萄花油層高分辨率層序地層學(xué)研究,進行了古龍油田葡萄花油層基準面旋回識別,建立了研究區(qū)高分辨率等時層序格架,得出葡萄花油層垂向上整體為水體先逐漸變淺—水退最大—水體加深—薩葡夾層水體達到相對最大的過程的結(jié)論。地層從東到西逐漸減薄。2.利用維水平切片對微構(gòu)造一一落實,小網(wǎng)格小等值線間距(一般1m)成圖。聯(lián)合應(yīng)用構(gòu)造趨勢面分析等技術(shù),有效地發(fā)現(xiàn)了構(gòu)造幅度小于5m的微幅度構(gòu)造。共發(fā)現(xiàn)160個微幅度構(gòu)造。3.利用SGR斷層封閉性評價方法,得出工區(qū)斷層封閉性好古60%以上,中等在40%-60%之間,差不到40%。4.在高分辨率層序地層劃分與對比基礎(chǔ)上,結(jié)合前人研究成果,對沉積體系、物源方向、沉積特征、沉積相、砂體類型、沉積模式等進行研究,并充分結(jié)合地震屬性成果,最終確定了研究區(qū)砂體空間展布。5.詳細剖析古龍油田葡萄花油層垂向、平面油水分布特征。劃分了葡萄花油層油藏類型,確定了各油藏類型的形成及分布規(guī)律。6.通過對古龍油田葡萄花油層生油條件及運移模式分析,結(jié)合油氣儲藏條件、圈閉條件及失利井分析,確定了該工區(qū)各個區(qū)塊的不同成藏因素。7.在前面高分辨率層序地層學(xué)、構(gòu)造及斷裂特征、沉積特征、儲層特征及成巖作用、成藏規(guī)律、主控因素以及油水分布規(guī)律研究基礎(chǔ)之上,結(jié)合油藏類型及試油試采井以及開發(fā)井產(chǎn)能等情況,預(yù)測了有利區(qū)塊,并優(yōu)選設(shè)計井位。
[Abstract]:For the reservoir distribution complex Gulong oilfield, the oil-water distribution of accurate prediction of oilfield, is to ensure the stable production of oil, improve the core recovery. Influenced by lithology and structure, area of oil-water distribution appears oil-water layer, oil water, underwater oil, oil-water layer between each other "and other characteristics combined with various means characterization of micro amplitude structures, sedimentary microfacies, reservoir conditions of oil and gas, is the oil-water distribution of reservoirs in Putaohua reservoir in Gulong oilfield improve understanding accuracy, find the key and favorable block wells. Favorable arrangement in the study area is mainly lithologic reservoir, followed by structural lithologic reservoir, the main oil-bearing formation for Putaohua section, the lithology in the longitudinal, transverse changes quickly, the reservoir distribution is not stable in space. In the process of continuous exploration and development of Gulong oilfield in gradually exposed sand deposition in this area The relationship between oil and water is very complex, the original reserves based on direct development of great risk, need to accurately understand the layers of sand body distribution and reservoir property change, the distribution of oil and water. In this paper, Gulong oilfield Putaohua reservoir as the main study area, to carry out oil reservoir seismic method combined with characterization in the standardization of logging data, combined with geological seismic horizon calibration based on the high resolution sequence stratigraphic division and correlation, many characterization methods of micro amplitude structures, layered segments depict different scale up river sand, breaking up the hierarchical oil-water distribution and reservoir Duan Yan type, Gulong oilfield of Putaohua reservoir in micro structure, reasonable and accurate to find out the distribution of sand bodies and distribution characteristics of fine accumulation controlling factors influence on the distribution of oil and water, the formation of Gulong oilfield Putaohua reservoir fine geologic research process, effective guidance To determine the favorable areas and favorable wells deployment. The main results are as follows: 1. the use of well logging, logging, seismic and other information, to carry out the Putaohua high-resolution sequence stratigraphy, the gulong oilfield Putaohua reservoir, the identification of base level cycles in the studied area was established as a high resolution sequence framework, the Putaohua oil reservoir the overall vertical water gradually becomes shallow water back to the maximum water - water to deepen Sapu dissection process the maximum relative conclusions. Strata from east to west is gradually thinning by.2. dimensional horizontal slice 11 implementation of micro structure, small small grid contour spacing (1m) combined with mapping. The structural trend surface analysis technology, effectively found the micro amplitude structure amplitude less than 5m. There were 160 micro amplitude structure using SGR.3. evaluation method of fault sealing, the fault sealing good old 60% Above, intermediate between 40%-60%, less than 40%.4. in the high resolution sequence stratigraphic division and correlation based on the results of previous studies, the sedimentary system, source direction, sedimentary characteristics, sedimentary facies, sand body types, sedimentary research mode, and combine the results of seismic attributes, and ultimately determine the study area space distribution of sand bodies of.5. detailed analysis of Gulong oilfield of Putaohua reservoir in the vertical plane, the oil-water distribution characteristics. The reservoirs in Putaohua reservoir types, determine the types of reservoir formation and distribution of.6. through the analysis of Putaohua oil conditions and migration patterns of Gulong oilfield grapes, combined with the oil and gas storage conditions, well analysis and defeat trap the reservoir conditions, determine the factors of.7. in high resolution sequence stratigraphy in the area in front of different blocks, tectonic and sedimentary characteristics and fracture characteristics, diagenesis and reservoir characteristics, accumulation, main Controlling factors and distribution of oil and water on the basis of the study, combined with the reservoir type and oil production wells and development wells and predict favorable blocks, and optimal design of wells.
