介绍了一种新型无荧光防塌降滤失剂YW 2 2的性能研究情况 ,它是一种油溶性单体和水溶性阳离子单体的共聚物。实验对YW 2 2的降失水效果、抑制性能、抗温性能、润滑性等指标进行了评价。室内及现场实验结果表明 ,YW 2 2有明显的降失水和防塌作用 ,能抗 16 0℃以上的高温 ,而且润滑效果好 ,综合结果显示YW 2 2是一种性能都极佳的钻井液处理剂
A new non-fluorescent anti-collapse fluid loss additive YW 2 2 is introduced. It is a copolymer of oil-soluble monomer and water-soluble cationic monomer. Experiments were conducted to evaluate the water loss effect, inhibition performance, temperature resistance and lubricity of YW 2 2. The results of laboratory and field tests show that YW 2 2 has obvious water loss and anti-collapse effects, can resist high temperatures above 160 ℃, and has good lubrication effects. The comprehensive results show that YW 2 2 is a well-behaved well Liquid treatment agent
