摘要:

介绍了一种新型无荧光防塌降滤失剂YW-22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-22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-22有明显的降失水和防塌作用,能抗160℃以上的高温,而且润滑效果好,综合结果显示YW-22是一种性能都极佳的钻井液处理剂。

关键词: 降滤失剂, 抑制剂, 实验室研究, 现场应用

Abstract:

A non-fluorescent shale/ filtration controller, YW-22,has been synthesized which is a copolymer of a water-soluble cationic monomer and an oil-soluble monomer. The performance evaluation conducting in laboratory and oilfield has indicated that YW-22 is a multifunctional additive. It has excellent performance in fluid loss control and shale inhibition, and can be used in high temperature drilling system. MeanwhileYW-22 can decrease the friction factor (Kf) significantly in drilling fluids. Its non-fluorescent property has been testified in laboratory and is of importance for well logging.

Key words: Filtration reducer, inhibitor, laboratory testing
