【摘要】：本文根據(jù)杏六區(qū)西部數(shù)據(jù)資料,應(yīng)用Petrel地質(zhì)建模軟件,在沉積相約束條件下建立杏六區(qū)西部儲層三維地質(zhì)模型。根據(jù)地質(zhì)建模結(jié)果和油藏生產(chǎn)動態(tài)數(shù)據(jù),應(yīng)用Eclipse軟件對產(chǎn)液量、含水率等進(jìn)行歷史擬合,對地質(zhì)儲量、采出程度進(jìn)行計(jì)算。在歷史擬合的基礎(chǔ)上,根據(jù)數(shù)值模擬結(jié)果分析目前和不調(diào)整預(yù)測到含水98%時(shí)縱向上和平面上剩余油分布情況,研究了杏六區(qū)西部補(bǔ)孔調(diào)整潛力。在此基礎(chǔ)上,結(jié)合區(qū)塊油層發(fā)育情況及原井網(wǎng)部署特點(diǎn),制定了薩Ⅱ油層組補(bǔ)孔原則。在沉積相帶圖上,嚴(yán)格根據(jù)補(bǔ)孔原則對薩Ⅱ油層組的三次加密井逐井逐層篩選。對篩選結(jié)果進(jìn)行數(shù)值模擬計(jì)算,根據(jù)剩余油分布以及水淹級別調(diào)整補(bǔ)孔層位,制定補(bǔ)孔層位方案。通過對比不同方案的開發(fā)效果和經(jīng)濟(jì)效益,得到了最優(yōu)補(bǔ)孔層位方案。在現(xiàn)井網(wǎng)生產(chǎn)預(yù)測的基礎(chǔ)上,選定在三次加密井不同含水級別對薩II油層組進(jìn)行補(bǔ)孔調(diào)整,用數(shù)值模擬方法預(yù)測不同補(bǔ)孔時(shí)機(jī)的開發(fā)指標(biāo)。方案預(yù)測時(shí),三次加密井的薩Ⅱ油層組和薩Ⅲ及以下油層組作為兩套層系分別監(jiān)控含水率變化,單井層系含水到達(dá)98%時(shí),即關(guān)掉該井該層系。對不同補(bǔ)孔時(shí)機(jī)方案進(jìn)行經(jīng)濟(jì)評價(jià),優(yōu)選出經(jīng)濟(jì)效益最好的兩個補(bǔ)孔時(shí)機(jī),加密補(bǔ)孔時(shí)間點(diǎn),對補(bǔ)孔時(shí)機(jī)方案進(jìn)行細(xì)化研究。用數(shù)值模擬方法預(yù)測細(xì)化方案的開發(fā)指標(biāo),結(jié)合經(jīng)濟(jì)評價(jià)給出杏六區(qū)西部薩Ⅱ油層組合理的補(bǔ)孔時(shí)機(jī)。
[Abstract]:Based on the data of the western part of Xingliu area, a 3D reservoir geological model of the western part of Xingliu area is established under the condition of sedimentary facies constraint by using the Petrel geological modeling software.According to the result of geological modeling and the data of reservoir production performance, Eclipse software is used to carry out historical fitting of liquid production and water cut, and the geological reserves and recovery degree are calculated.On the basis of historical fitting, according to the results of numerical simulation, the distribution of remaining oil in longitudinally and on the plane at the time of 98% water cut is analyzed, and the adjustment potential of hole filling in the west of Xing6 region is studied.On this basis, combined with the development of the reservoir and the characteristics of the original well pattern arrangement, the principle of filling holes in the formation of the sa 鈪，
