Aim at the difficulty of separate layer to high auifer bed,fractured and high permeability formation,The copolymer which made from 2-acrylamido-2-methyl propane sulfonic acid (AMPS) and acrylamide (AM) was synthesized, which are root of the chemical character of polyvinyl alcohol (PVA).
针对常用降失水剂在工程应用中存在低于临界掺量时滤失失控,配套外加剂可选范围小,室内测试的滤失量数据难以代表井下实际情况,水泥胶结测井解释困难,对高含水、裂缝性和高渗透地层很难实现优质封隔的问题,合成了以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)与丙烯酰胺(AM)的共聚物为主体的降失水剂,并对其降滤失能力、稠化性能、抗压强度、抗盐性能进行了评价。

This paper presents a new lost circulation additive for high permeability formation or faulted bed drilling.
钻井过程中遇到低压或压力衰竭的高渗透地层,经常会发生严重的井漏,通常使用堵漏剂和注水泥塞来防止井漏。
