Cross-polymer gel has limited application in profile controlling of high-temperature and high-salinity reservoirs. Reservoirs in Tarim Basin, NW China, were geologically developed in marine environment with high temperature and high salinity. To address the problem of deep profile modification in Tarim Basin, profile controlling agent with abio-gel coating (WJSTP) is developed by taking advantage of the multi-valence cations concentrated in both the formation and injection water and injects a compounded...

Cross-polymer gel has limited application in profile controlling of high-temperature and high-salinity reservoirs. Reservoirs in Tarim Basin, NW China, were geologically developed in marine environment with high temperature and high salinity. To address the problem of deep profile modification in Tarim Basin, profile controlling agent with abio-gel coating (WJSTP) is developed by taking advantage of the multi-valence cations concentrated in both the formation and injection water and injects a compounded silicate to react with the cations to form abio-gel with the same density as water. Beaker test shows that the gel has desirable properties of heat resistance, salinity resistance and long-term stability. Core flood tests verify that, by slug injection, the process can gradually build long lasting residue resistance factor (RRF) for water flow in high permeability streaks, indicating a "layering" or "coating" mechanism.

交联聚合物调剖在高温、高地层水矿化度条件下的应用受到限制。为了解决塔里木盆地高温、高矿化度地层水深层油藏的调剖问题,研究了WJSTP无机凝胶涂层调剖剂。该调剖剂与高矿化度地层水反应后形成密度与水相当的无机凝胶,以吸附涂层方式在岩石骨架表面逐渐结垢,形成无机凝胶涂层,使地层中的流动通道逐渐变窄而造成流动阻力,达到使地层流体转向、扩大波及体积的目的。采用瓶试实验和岩心物理模拟方法,研究了该调剖剂与油田水反应的凝胶化性能,以及无机凝胶涂层对多孔介质的封堵性能,并通过管流试验模拟涂层对大孔道的封堵效果。结果表明,WJSTP调剖剂与高矿化度地层水形成的无机凝胶具有极好的耐温、耐盐及热稳定性能,通过多次涂层,可实现多孔介质中不同程度的封堵,在管流模型中获得同样的无机凝胶涂层封堵效果。图3表1参7

According to the geologic feature and waterflood performance of low-permeability fractured reservoir in Panguliang Chang-6 reservoir of Changqing Oil Field,a compound deep profile modification system composed of pre- crosslinked particle/waterflood fluid diversion agent/polymer gel was prepared.Pre-crosslinked particle and waterflood fluid diversion agent had a high expansion ratio and played a role to plug big fractured water paths.The polymer gel played a role to displace residual oil in medium or small fractures effectively.The technology was used in Well Pan59-28 and Well Pan49-28 and the oil yield increased 3 564 t in 14 months and 3801t in 16 months respectively.

长庆油田盘古梁长6油藏属于低渗透裂缝性油藏,严重影响到水驱油波及效率。针对该油藏地质特征和见水状况,研制了预交联颗粒/水驱流向改变剂/聚合物弱凝胶复合深部调驱体系,其中预交联颗粒/水驱流向改变剂具有较高的膨胀率,发挥了深部调剖作用,有效封堵大裂缝出水通道;聚合物弱凝胶主要发挥了驱油作用,有效启动中小裂缝中剩余油。利用该调驱体系在两井组进行了矿场应用,结果两井组在14和15个月中分别增油3564.38t和3801.00t。
