【摘要】：薩中開發(fā)區(qū)一類油層聚合物驅(qū)自1996年投入工業(yè)化應(yīng)用以來,經(jīng)歷了從中分、高分到超高分及從普通濃度到高濃度的研究推廣過程,使得提高采收率的幅度不斷增加。但從注聚過程中油層的動(dòng)用狀況看,縱向上滲透率差異較大的單井以及油層性質(zhì)相對(duì)較差的層,它們的動(dòng)用狀況不理想。近幾年,相關(guān)研究單位對(duì)交替注入進(jìn)行了深入研究,得出交替注入可以提高油層采收率,同時(shí)也可以節(jié)約聚合物干粉。按照大慶油田有限責(zé)任公司聚驅(qū)“520”工作目標(biāo)和“四最”要求,在薩中開發(fā)區(qū)選取注聚區(qū)塊——南一區(qū)西東塊2號(hào)注入站作為試驗(yàn)區(qū),開展不同分子量、不同濃度的周期交替注入試驗(yàn),探索進(jìn)一步提高采收率及節(jié)約干粉的新途徑。本文在對(duì)試驗(yàn)區(qū)油藏精細(xì)描述的基礎(chǔ)上,對(duì)南一區(qū)西東塊2號(hào)注入站一類油層的儲(chǔ)層特征、儲(chǔ)量分布、現(xiàn)井網(wǎng)的動(dòng)用狀況及剩余油潛力進(jìn)行了系統(tǒng)分析;通過不同分子量聚合物的周期交替注聚,并結(jié)合壓裂、分注、調(diào)剖等措施提高了薄差油層注入能力和動(dòng)用程度,高效利用聚合物,降低了聚合物費(fèi)用,進(jìn)一步改善區(qū)塊開發(fā)效果。試驗(yàn)階段提高采收率達(dá)到12%,節(jié)約化學(xué)劑成本21.7%。本次試驗(yàn)成果可應(yīng)用于主力油層125m井距聚驅(qū)工業(yè)化區(qū)塊,在不影響最終提高采收率的前提下,節(jié)約聚合物費(fèi)用,降低成本,體現(xiàn)經(jīng)濟(jì)效益的最大化,對(duì)于主力油層小井距以及二類油層聚合物驅(qū)交替注入的研究應(yīng)用具有指導(dǎo)和借鑒意義。
[Abstract]:Since the first class of reservoir polymer flooding in Sazhong Development Zone was put into industrial application in 1996, it has gone through the research and popularization process of middle score, high score to super high score and from ordinary concentration to high concentration, which makes the range of improving oil recovery increasing. However, from the point of view of the production situation of the reservoir in the process of polymer injection, the production condition of the single well with great permeability difference and the layer with relatively poor reservoir properties is not ideal. In recent years, the relevant research units have carried out in-depth research on alternating injection, and it is concluded that alternating injection can improve reservoir recovery and save polymer dry powder at the same time. According to the target of polymer flooding "520" and the requirements of "four best" in Daqing Oilfield Co., Ltd., the injection station No. 2 of Xidong Block, Nanyi District, is selected as the experimental area in Sazhong Development Zone to carry out different molecular weights. In order to explore a new way to further improve oil recovery and save dry powder, different concentrations of cyclic alternating injection test were used to explore a new way to further improve oil recovery and save dry powder. Based on the fine description of the reservoir in the experimental area, this paper makes a systematic analysis of the reservoir characteristics, reserve distribution, production status of the present well pattern and the remaining oil potential of the No. 2 injection station in the Xidong Block of the South 1 area. Through cyclic alternating polymer injection of different molecular weight polymers, combined with fracturing, split injection, profile control and other measures, the injection ability and production degree of thin difference reservoir are improved, the polymer is used efficiently, and the cost of polymer is reduced. Further improve the development effect of the block. In the experimental stage, the oil recovery is increased by 12% and the cost of chemical agent is saved by 21.7%. The test results can be applied to 125 m well distance polymer flooding industrial block of the main reservoir. Without affecting the final improvement of oil recovery, the polymer cost can be saved, the cost can be reduced, and the economic benefit can be maximized. It has guiding and reference significance for the research and application of small well spacing in the main reservoir and alternating injection of polymer flooding in the second type of reservoir.
