【摘要】：本研究針對(duì)射孔完井井筒附近非達(dá)西復(fù)雜流動(dòng)特征和聚合物驅(qū)非牛頓流體特性,分析了鉆完井過(guò)程中儲(chǔ)層傷害機(jī)理、自主設(shè)計(jì)并開(kāi)展了射孔傷害參數(shù)測(cè)定實(shí)驗(yàn)、數(shù)值模擬研究了聚合物驅(qū)射孔完井井筒附近復(fù)雜非牛頓非達(dá)西流動(dòng)規(guī)律、針對(duì)水驅(qū)開(kāi)發(fā)和聚合物驅(qū)開(kāi)發(fā)特征評(píng)價(jià)了不同類型射孔彈適用條件并進(jìn)行了現(xiàn)場(chǎng)驗(yàn)證。本文主要開(kāi)展了以下三方面工作:(1)分析了鉆井過(guò)程中儲(chǔ)層污染機(jī)理和射孔壓實(shí)傷害機(jī)理�；谀囡灣两凳睾惴匠�、沖蝕方程和達(dá)西方程建立了鉆井污染深度和污染程度預(yù)測(cè)模型,并針對(duì)目標(biāo)區(qū)塊污染深度和污染程度進(jìn)行預(yù)測(cè)。自主設(shè)計(jì)并開(kāi)展了射孔傷害參數(shù)測(cè)定實(shí)驗(yàn),實(shí)驗(yàn)結(jié)果表明:滲透率小于1×10-3μm2條件下射孔壓實(shí)厚度在10-12mm之間,滲透率大于10×10-3μm2條件下射孔壓實(shí)厚度在10-18mm之間。(2)建立了射孔完井井筒附近非牛頓非達(dá)西滲流模型,設(shè)計(jì)并開(kāi)展了聚合物溶液在多孔介質(zhì)中的流動(dòng)粘度測(cè)定實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明:流動(dòng)粘度隨聚合物分子量和巖心滲透率的增加而增大;聚合物溶液在巖心中的流動(dòng)粘度遠(yuǎn)小于溶液表觀粘度,按照表觀粘度計(jì)算聚合物在油藏中的壓降會(huì)產(chǎn)生較大誤差,因此在實(shí)際生產(chǎn)過(guò)程中計(jì)算油藏壓降時(shí)應(yīng)采用聚合物溶液真實(shí)流動(dòng)粘度。本實(shí)驗(yàn)測(cè)定聚合物溶液流動(dòng)粘度為聚合物驅(qū)數(shù)值模擬計(jì)算提供了科學(xué)依據(jù)。(3)基于射孔完井井筒附近非牛頓非達(dá)西滲流模型和聚合物溶液在多孔介質(zhì)中的流動(dòng)粘度測(cè)定結(jié)果,數(shù)值模擬研究了水驅(qū)開(kāi)發(fā)和聚合物驅(qū)開(kāi)發(fā)條件下不同類型射孔彈完井的流動(dòng)效率,給出了水驅(qū)開(kāi)發(fā)和聚合物驅(qū)開(kāi)發(fā)條件下射孔彈效果排序:水驅(qū)開(kāi)發(fā)條件下深穿透(穿深639mm)射孔彈效果最好、常規(guī)射孔彈次之、大孔徑(孔徑16mm)射孔彈效果最差,聚驅(qū)開(kāi)發(fā)條件下大孔徑射孔彈效果優(yōu)于常規(guī)射孔彈,但還是深穿透彈最好。本文研究成果豐富了聚合物驅(qū)射孔彈優(yōu)選及射孔參數(shù)優(yōu)化設(shè)計(jì)理論,對(duì)聚合物驅(qū)或三元復(fù)合驅(qū)射孔完井現(xiàn)場(chǎng)施工設(shè)計(jì)具有重要工程指導(dǎo)意義。
[Abstract]:According to the complex flow characteristics of non-Darcy and non-Newtonian fluid characteristics of polymer flooding near perforated completion wellbore, the damage mechanism of reservoir during drilling and completion is analyzed, and the experiment of measurement of perforating damage parameters is designed and carried out independently. The complex non-Newtonian non-Darcy flow law near the well bore of polymer flooding perforation and completion is studied numerically. According to the characteristics of water flooding and polymer flooding, the suitable conditions of different types of perforating bullets are evaluated and verified in the field. The main work of this paper is as follows: (1) the mechanism of reservoir pollution and perforation compaction damage during drilling is analyzed. Based on the conservation equation of mud cake settlement, erosion equation and Darcy equation, the prediction model of drilling pollution depth and pollution degree is established, and the pollution depth and pollution degree of target block are predicted. The experiment of perforating damage parameters was designed and carried out. The experimental results show that the perforation compaction thickness is between 10-12mm when the permeability is less than 1 脳 10 ~ (-3) 渭 m ~ (2). The perforation compaction thickness is between 10 脳 10 ~ (-3) 渭 m ~ 2 and 10 脳 10 ~ (-3) 渭 m ~ (2). (2) the non-Newtonian non-Darcy percolation model near the perforating completion wellbore is established, and the flow viscosity measurement experiment of polymer solution in porous media is designed and carried out. The experimental results show that the flow viscosity increases with the increase of polymer molecular weight and core permeability, and the flow viscosity of polymer solution in the core is much smaller than the apparent viscosity of the solution. The calculation of the pressure drop of polymer in the reservoir according to the apparent viscosity will result in a big error, so the real flow viscosity of polymer solution should be used in the calculation of the pressure drop of the reservoir in the actual production process. The experimental measurement of flow viscosity of polymer solution provides a scientific basis for the numerical simulation of polymer flooding. (3) based on the non-Newtonian non-Darcy percolation model near the perforated completion well and the measurement results of the flow viscosity of polymer solution in porous media, The flow efficiency of different types of perforating projectile completion under the conditions of water drive development and polymer flooding development is studied numerically. The order of perforating projectile effect under water drive development and polymer flooding development is given. Under water drive development condition, deep penetration (639mm) perforator is the best, conventional perforator is the second, and large aperture (16mm) perforator is the worst. Under the condition of polymer flooding, the effect of large aperture projectile is better than that of conventional projectile, but it is the best in deep penetrating projectile. The research results in this paper enrich the theory of optimization of perforation elasticity and perforation parameters of polymer flooding, and have important engineering guidance significance for the field design of perforation completion in polymer flooding or ASP flooding.
