【摘要】：化學(xué)驅(qū)是我國水驅(qū)油田開發(fā)后期重要的提高采收率技術(shù),由于聚合物驅(qū)在低滲油田注入困難、指進(jìn)現(xiàn)象嚴(yán)重及會(huì)污染地面環(huán)境;堿水驅(qū)存在堿耗、生成表面活性劑有限等問題,開展了濃表面活性劑驅(qū)油技術(shù)——微乳液驅(qū)油技術(shù),該技術(shù)對于提高低滲油氣藏驅(qū)油效率具有重要的指導(dǎo)意義。以實(shí)驗(yàn)室自制的陰離子型表面活性劑XSY為主要成分,利用正交試驗(yàn)設(shè)計(jì)優(yōu)化出均相的中相微乳液最佳配方為:正辛烷與水各5ml,XSY含量2.5%,醇含量8%,Na Cl含量5%~6%,最佳配方下的均相微乳具有良好的增溶能力、與油水間的界面張力可以降低到10-3m N/m數(shù)量級、穩(wěn)定性好及注入能力強(qiáng)等優(yōu)點(diǎn)。采用醇掃描法和鹽度掃描法對鹽種類及濃度、醇種類及濃度、溫度及p H等因素對形成均相微乳液相態(tài)、增溶能力及界面張力進(jìn)行了研究。利用巖心實(shí)驗(yàn)研究了微乳液體系注入方式、微乳液段塞體積大小、水驅(qū)速度對驅(qū)油效率的影響。實(shí)驗(yàn)結(jié)果表明:采用微乳液段塞可以提高采收率10%~15%,隨著微乳液注入段塞的增大,增加采收率幾乎呈直線上升,并且隨著水驅(qū)速度的增加,巖心注入微乳液段塞后的二次水驅(qū)增加的采收率值降低。
[Abstract]:Chemical flooding is an important technology to improve oil recovery in the later stage of water flooding in China. Due to the difficulty of polymer flooding in low permeability oil fields, the phenomenon of flooding is serious and will pollute the surface environment, the alkali consumption in alkaline water flooding is limited, and the surface active agents are limited, etc. The concentrated surfactant flooding technology-microemulsion flooding technology is developed, which has important guiding significance for improving the oil displacement efficiency of low permeability reservoirs. The anionic surfactant XSY made by the laboratory is used as the main component. The optimum formulation of homogeneous mesophase microemulsion was obtained by orthogonal design. The optimum formula was as follows: the content of n-octane and water was 2.5%, the content of alcohol was 8%, and the content of NaCl was 5%. The homogeneous microemulsion had good solubilization ability under the optimum formulation. The interfacial tension between oil and water can be reduced to the order of 10-3m N / m, the stability is good and the injection ability is strong. The kinds and concentrations of salts, kinds and concentrations of alcohols are determined by alcohol scanning and salinity scanning. The formation of homogeneous microemulsion phase state, solubilization ability and interfacial tension were studied by temperature and pH. The injection mode of microemulsion system and the volume of microemulsion slug were studied by core experiment. The effect of water flooding speed on oil displacement efficiency. The experimental results show that the oil recovery factor can be increased by 10% and 15% by using microemulsion slug. With the increase of microemulsion injection slug, the increase of oil recovery is almost straight up, and with the increase of water flooding velocity, The oil recovery value of secondary water flooding increased after core injection microemulsion slug.
