1. In the high-temperature conditions, the use of saline water slurry make laboratory work more to obtain the desired thickening, filtration and deep well under the conditions of strength, the amount of additives are often too large. 2. In order to reduce the formation of cement and potential side effects may number of filtration strata, it is necessary to drop the use of water loss in order to ensure construction safety. 3. Must realize that when the comprehensive performance of cement to meet the API specification, can be used for on-site construction. 4. Polymer flooding by 3 to increase oil recovery mechanism: ① to improve sweep efficiency; ② to improve the micro-displacement efficiency; ③ This combination of two mechanisms. 2. HPAM solution in the end than the low concentration such as the concentration of polymer solution other better, why not entirely clear. 3. Dissolved in the solution of the molecules will affect the shape and size of the mobile solution performance. 4. Under normal circumstances, wells injection before the recovery is directly proportional to the volume of water.1楼的是用机器翻译的。
