【摘要】：紅崗油田薩爾圖油藏南部為2004年開始相繼進(jìn)行井網(wǎng)加密,形成反五+反七+反九點(diǎn)注水井網(wǎng)模式,該井網(wǎng)模式在加密后初期取得一定的效果,但是后期分層產(chǎn)出狀況、分層注采關(guān)系認(rèn)識(shí)難度很大,導(dǎo)致平面矛盾凸顯,含水快速上升,大量油井關(guān)停,產(chǎn)量快速遞減。油井再次動(dòng)用難度大,挖潛難度大,難以做到有的放矢。本次根據(jù)2006年地質(zhì)建模的研究成果,將后期新鉆井40口的小層進(jìn)行精細(xì)劃分對(duì)比,形成可用的數(shù)據(jù)體。將新井的小層數(shù)據(jù)導(dǎo)入原有的地質(zhì)模型中,并且將原模型的平面網(wǎng)格由50×50米細(xì)化為30×30米,生成新的完善的地質(zhì)數(shù)據(jù)體,內(nèi)容包括小層厚度、孔隙度、滲透率、泥質(zhì)含量、含油飽和度、含水飽和度、凈毛比。將細(xì)化后的地質(zhì)模型進(jìn)行粗化,符合開展數(shù)值模擬的條件。通過采用Eclipse方法進(jìn)行數(shù)值模擬,將Eclipse的解釋結(jié)果進(jìn)行剩余油分布預(yù)測(cè)及定量化描述。數(shù)值模型建立后研究探尋各個(gè)小層剩余油分布的主要位置,分析探索目前影響剩余油分布的主控因素是儲(chǔ)層的非均質(zhì)性強(qiáng)。并且為了對(duì)研究成果的可靠性進(jìn)行驗(yàn)證,對(duì)剩余油富集部位實(shí)施挖潛措施,取得了很好的效果。
[Abstract]:In the south of Saltu reservoir of Honggang Oilfield, the well pattern was infilled successively in 2004, forming the anti-five anti-seven anti-9-point pattern of water injection well pattern. The pattern of well pattern obtained certain effect at the initial stage of infilling, but in the late stage of stratified production, The recognition of stratified injection-production relationship is very difficult, which leads to the prominent plane contradiction, the rapid rise of water cut, the closure of a large number of oil wells, and the rapid decline of production. Oil wells are difficult to produce again, difficult to tap potential, difficult to achieve targeted. According to the research results of geological modeling in 2006, this paper makes fine division and comparison of 40 layers of new drilling in the later stage to form the usable data body. The small layer data of the new well are introduced into the original geological model, and the plane grid of the original model is refined from 50 脳 50 meters to 30 脳 30 meters to form a new and perfect geological data body, which includes the thickness of the layer, porosity, permeability, mud content, etc. Oil saturation, water saturation, net wool ratio. Coarsening the refined geological model accords with the condition of numerical simulation. The residual oil distribution is predicted and quantitatively described by Eclipse method. After the numerical model was established, the main location of residual oil distribution in each sublayer was explored, and the main controlling factor affecting remaining oil distribution at present was the strong heterogeneity of reservoir. And in order to verify the reliability of the research results, the remaining oil enrichment site of the implementation of potential tapping measures, achieved good results.
