摘要
目前国内常用支撑剂普遍抗酸蚀性能差、密度高、抗压强度低,难以满足塔河油田压裂与酸化复合改造工艺的要求.为此,研制开发了新型高强度支撑剂H-1.其性能测试表明,酸溶解度为1.6%,在86 MPa下的破碎率为2.1%,在高温、高闭合应力及强酸性环境中可保持较高的导流能力,可满足塔河油田压裂与酸化复合改造的要求.
According to the performances of all common domestic high-strength ceramsites,the common domestic proppants cannot meet the requirements of the fracturing and acidizing technology in Tahe oilfield to proppant because they have bad acid-resistance,higher density and lower strength.For this reason,a new high-strength proppant H-1 is developed for the oilfield.The measuring results of its performance show that,the acid solubility of the proppant is 1.6%,the breaking rate of it is 2.1% at 86 MPa.The proppant can make formation have higher flow conductivity under high-temperature,high closure stress and acidic environment,and it can well meet the requirements of the fracturing and acidizing technology in Tahe oilfield.
