摘　　要：采用乳液聚合方法合成一种多功能钻井液添加剂ARJ,该剂具有一剂多效的特点,使用方便。对ARJ进行了室内性能评价,实验结果表明,ARJ具有较好的增粘性、降滤失性、抑制性及润滑性。抗温、抗盐、抗钙性试验表明,ARJ在160℃、30％盐水钻井液及3％含钙钻井液中性能稳定,适于在较复杂地层的钻进中应用。A multifunctional additive ARJ for drilling fluid was synthesized by emulsion polymerization. The experiment results in laboratory showed that ARJ had good performance in increasing viscosity, lubricity, and inhibiting a-bility. The experiments of heat resistance and calcium and salt tolerance showed that performance of ARJ in drilling fluid containing 30% salt and 3% calcium at 160℃ was stable. It was adaptable to application in complex layer.
