摘要： A well treatment composition is formed from an aqueous crosslinkable hydrated polymer solution. Combined with the polymer solution is a solid boric acid or borate crosslinking agent and a solid metal oxide or metal hydroxide pH buffering agent that has limited solubility (less than 100 kg/m3 at 20° C.) within the polymer solution that provides the solution with a pH of from about 8 to about 11. The composition may be introduced into a subterranean formation through a wellbore that penetrates the formation. The composition may provide at least one of shortened shear recovery time and an increase in the thermal stability of the aqueous polymer solution.
摘要翻译：由水性可交联水合聚合物溶液形成良好的处理组合物。与聚合物溶液结合是固体硼酸或硼酸盐交联剂和固体金属氧化物或金属氢氧化物pH缓冲剂，其溶解度有限（在20℃下小于100kg / m 3）在提供约8至约11的pH的溶液的聚合物溶液内。可以通过穿透地层的井筒将组合物引入到地下地层中。组合物可以提供缩短的剪切恢复时间和聚合物水溶液的热稳定性的增加中的至少一种。
