关于Eliasville聚合物驱的动机是在这个含轻油的石灰岩地层设计水驱时产生的。早在联合之命。人们就认识纣不利的油层水驱将在，并开始实验室工作，来论证用一些不同聚丙烯蔬胶提高水约粘度降低水的流度的好处。为了设计策合物驱。结合类验室的聚合物惨淡和已知的Caddo水驱破态炎有了计算机模拟。为了确定聚会价伪注入能力进行了三次试注，为了确定及合物的地不粘度进行了压火试井。每次试住都包括一口可以估算聚合物滞留量以及短时期内提高采收率的井网外的生产井、在试注及模拟工作基础上实施了大规模的聚合物驱计划。最佳的段塞体积需要300000001b（13607.7t）乳状聚合物。文中介绍了这样大批量聚合物的混合及输送设合。为了保证在地层射中最大的液体粘度，设计了一种低剪切的聚合物流控制方法。产品纷规格鉴发交货之前检验、并且注入波的质量要在专用实验室监测。油田规模控聚合物的初期开采反应，与试住时生产并纷反应类似。油田早斯反应令人鼓舞。但注盐水对段塞完整性的影响以及扩大井距对采收率的影响还有待确定。
The motivation for Eliasville polymer flooding is created when designing waterfloods in this light oil-bearing limestone formation. As early as the joint life. People will recognize that the unfavorable reservoir water flooding will begin and laboratory work will begin to demonstrate the benefits of using some different polypropylene vegetable gels to increase water viscosity and reduce the flow of water. In order to design a compound drive. Computer simulations were performed with a combination of laboratory polymer bleak and known Caddo water flooding. Three test runs were conducted to determine the fake injection ability of the party, and a pressure well test was conducted to determine the in-situ non-viscosity of the compound. Each trial included a production well outside of the well network to estimate polymer retention and short-term recovery, and a large scale polymer flooding program was implemented on the basis of pilot and simulation work. The optimum slug volume requires 30,000,000 lb (13,607.7 t) of a milky polymer. This article describes such a large number of polymer mixing and conveying facilities. In order to ensure the maximum liquid viscosity in the formation shot, a low shear polymer flow control method was designed. Product quality specifications before delivery inspection, and injection wave quality to be monitored in a dedicated laboratory. Oilfield scale-controlled polymer initial recovery reaction, and production and trial when the reaction is similar. The response of the oil field has been encouraging. However, the effect of injection of brine on slug integrity and the effect of expanding well spacing on oil recovery have yet to be determined.
