【摘要】：為明確大慶長垣外圍特低滲透儲層微觀孔喉結(jié)構(gòu)與剩余油分布的關(guān)系,文中選取該地區(qū)30塊天然巖心進(jìn)行了水驅(qū)油實(shí)驗(yàn),應(yīng)用熒光顯微鏡與金相顯微鏡觀察驅(qū)油后天然巖心的自然斷面。利用景深融合技術(shù)對拍攝的熒光照片與金相照片進(jìn)行加工處理,并利用測量軟件測定了孔隙半徑、喉道半徑與微觀剩余油飽和度,對孔隙半徑、喉道半徑與剩余油分布的關(guān)系進(jìn)行了研究。長垣外圍特低滲油藏儲層巖石喉道半徑普遍較小,目前條件難以取得理想的水驅(qū)開發(fā)效果,需作進(jìn)一步開發(fā)調(diào)整。
[Abstract]:In order to clarify the relationship between micro pore throat structure and residual oil distribution in ultra-low permeability reservoir around Daqing Placanticline, 30 natural cores in this area were selected to carry out water flooding experiments.The natural section of natural core after oil displacement was observed by fluorescence microscope and metallographic microscope.The fluorescence and metallographic photographs were processed by depth of field fusion technique, and the pore radius, throat radius and micro residual oil saturation were measured by measuring software.The relationship between throat radius and remaining oil distribution was studied.The radius of rock throat is generally small in the extra-low permeability reservoir around Changyuan, so it is difficult to obtain ideal water drive development effect at present, so it is necessary to make further development adjustment.
