| 摘 要： | 长封固井段和低压易漏井段等复杂井段通常利用低密度水泥浆进行固井,西南石油大学与胜利油田钻井工艺研究院合作开发的实心低密度水泥浆体系,具有密度稳定、早期强度高和成本较低等优点,但存在失水量偏大和胶结能力较低的问题。采用苯乙烯、甲基丙烯酸甲酯和丙烯酸正丁酯三元共聚,制得一种新型胶乳,并应用于实心低密度水泥中。实验结果表明,失水量降低20%,有效减少体积收缩,提高胶结强度30%以上。SEM结果显示,水泥石结构致密,质量较好。

| Abstract: | Low -density cements were often applied in long cementing intervals and low pressure intervals. The solid low - density cementing system developed by Southwest Petroleum University and Research Institute of Drilling Technology of Shengli Oilfield Company had the advantages of stable density, high early strength and low cost, but the disadvantages of high water loss and weak cementing strength also existed. A novel latex was synthesized by copolymerization from styrene, methyl methacrylate and n -butyl acrylate. The latex was evaluated in low-density cement. The results showed that the water loss was decreased 20%, volume contraction was reduced effectively and cementing strength was increased 30% above. The SEM images indicated that cement were in compact structures. |
