摘要
根据钻进情况,目标井需要在固井完成后进行酸化压裂完井作业。需要一种适用于酸化压裂的水泥浆体系,要求弹性模量低于6GPa,抗拉强度高于3MPa。经过严格的材料研选与水泥浆性能优化,成功构建出一套具有低弹性模量,高抗拉强度的水泥浆体系,弹性模量为5.8GPa,抗拉强度为3.2MPa,具有优异的力学性能,满足酸化压裂作业需求并成功应用于目标区块。
Abstract
According to the drilling situation, the target well needed to proceed acid fracturing completion operations after cementing operation was completed. A cement slurry system suitable for acid fracturing was required, which showed have elastic modulus below 6GPa and tensile strength above 3MPa.After strict material selection and performance optimization for cement slurry, a cement slurry system with low elastic modulus and high tensile strength had been successfully constructed. The results showed that its elastic modulus was 5.8 GPa and its tensile strength was 3.2 MPa, which had excellent mechanical properties and could meet the requirements of acid fracturing operations. Then, the cement slurry was successfully applied to the target block.
