【摘要】：各向異性矩形油藏滲流機(jī)理的研究具有非常重要的現(xiàn)實(shí)意義。正確認(rèn)識(shí)油藏滲透率各向異性有利于油田的產(chǎn)能預(yù)測(cè)、尋找水驅(qū)油過(guò)程剩余油的分布、尋找油田長(zhǎng)期注水開(kāi)發(fā)引起的高滲透帶以及三次采油。由于儲(chǔ)層滲透率各向異性影響介質(zhì)的滲流過(guò)程,因此油氣藏的各向異性不可忽略,故不能用均質(zhì)儲(chǔ)層的壓力動(dòng)態(tài)和產(chǎn)能曲線(xiàn)來(lái)代替各向異性?xún)?chǔ)層的壓力動(dòng)態(tài)和產(chǎn)能曲線(xiàn)。本文首先運(yùn)用點(diǎn)源函數(shù)和Newman乘積的思想得到各向異性矩形油藏普通直井的解,再運(yùn)用匯源積分方法得到各向異性矩形油藏?zé)o限導(dǎo)流裂縫的解,最后運(yùn)用有限導(dǎo)流函數(shù)的思想得到了該斜裂縫模型的有限導(dǎo)流裂縫解。本文研究了儲(chǔ)層各向異性、斜裂縫與滲透率主軸的夾角、裂縫導(dǎo)流能力等對(duì)壓力動(dòng)態(tài)和產(chǎn)能曲線(xiàn)的影響,并得到如下結(jié)論:1)各向異性矩形油藏的滲流特征與均質(zhì)儲(chǔ)層的矩形油藏滲流特征存在著明顯區(qū)別,這主要體現(xiàn)在儲(chǔ)層各向異性影響了儲(chǔ)層滲流方式,它主要表現(xiàn)在滲流的早期階段;2)在各向異性矩形油藏的研究過(guò)程中,發(fā)現(xiàn)儲(chǔ)層各向異性對(duì)壓力動(dòng)態(tài)和產(chǎn)能曲線(xiàn)的影響主要發(fā)生在早期線(xiàn)性滲流階段、中間徑向流階段到擬穩(wěn)態(tài)階段之間的過(guò)渡段;3)在各向異性矩形油藏垂直裂縫井的研究中,發(fā)現(xiàn)斜裂縫與滲透率主軸的夾角對(duì)壓力動(dòng)態(tài)和理論產(chǎn)能曲線(xiàn)的影響主要發(fā)生在早期線(xiàn)性滲流階段和中間徑向滲流階段;4)在各向異性矩形油藏有限導(dǎo)流裂縫的研究中,發(fā)現(xiàn)有限導(dǎo)流能力到壓力動(dòng)態(tài)和理論產(chǎn)能曲線(xiàn)的影響主要發(fā)生在早期線(xiàn)性流階段�；谏鲜鲅芯砍晒�,本文對(duì)于各向異性?xún)?chǔ)層的開(kāi)發(fā)提供了理論的依據(jù),本文得到的理論產(chǎn)量遞減曲線(xiàn)和累計(jì)產(chǎn)能曲線(xiàn)為油藏的產(chǎn)量預(yù)測(cè)提供了依據(jù),同時(shí)為后期油田開(kāi)發(fā)方案設(shè)計(jì)提供了理論支撐。
[Abstract]:The study of percolation mechanism in anisotropic rectangular reservoirs is of great practical significance. The correct understanding of reservoir permeability anisotropy is conducive to the prediction of oilfield productivity, the search for the distribution of remaining oil in the process of water flooding, the search for high permeability zones and tertiary oil recovery caused by long-term waterflooding in oil fields. Because the anisotropy of reservoir permeability affects the percolation process of medium, the anisotropy of oil and gas reservoir can not be ignored, so the pressure performance and productivity curve of homogeneous reservoir can not be replaced by the pressure performance and productivity curve of anisotropic reservoir. In this paper, the point source function and Newman product are used to obtain the solution of normal straight well in anisotropic rectangular reservoir, and then the solution of infinite diversion fracture in anisotropic rectangular reservoir is obtained by Huiyuan integral method. Finally, the finite diversion crack solution of the oblique crack model is obtained by using the idea of finite diversion function. In this paper, the effects of reservoir anisotropy, angle between oblique fracture and permeability spindle and fracture conductivity on pressure performance and productivity curve are studied. The following conclusions are obtained: 1) the percolation characteristics of anisotropic rectangular reservoirs are obviously different from those of homogeneous rectangular reservoirs, which is mainly reflected in the reservoir anisotropy affecting the reservoir percolation mode. In the process of studying anisotropic rectangular reservoir, it is found that the influence of reservoir anisotropy on pressure performance and productivity curve mainly occurs in the early phase of linear percolation. In the study of vertical fractured wells in anisotropic rectangular reservoirs, It is found that the influence of angle between oblique fracture and permeability spindle on pressure dynamics and theoretical productivity curve mainly occurs in the early linear percolation stage and intermediate radial percolation stage (4) in the study of finite conductivity fractures in anisotropic rectangular reservoirs. It is found that the influence of the finite conductivity to the pressure dynamics and the theoretical productivity curve mainly occurs in the early linear flow stage. Based on the above research results, this paper provides a theoretical basis for the development of anisotropic reservoirs. The theoretical production decline curve and cumulative productivity curve obtained in this paper provide the basis for the reservoir production prediction. At the same time, it provides the theoretical support for the later stage oilfield development scheme design.
