摘要:

针对某气田注水采气过程中，震旦系和二迭系两种地层水单轮、混输产生ＣａＣＯ３、ＭｇＣＯ３、ＢａＣＯ３垢，特别是混输中产生ＢａＳＯ４垢的现状，模拟地层水，对９种油田常用防垢剂和２种知制防垢剂进行了评价。从中筛选出对两种地层水单输和混输均有较好效果的３种防垢剂ＷＳ－２１３Ａ、ＨＥＤＰ和ＡＴＭＰ；再用正交试验法对３种防垢 垢试验条件进行优化，得出同时满足两种地层水单输和混输防垢的较优实验条件。即防垢剂选用

Abstract:

The tendency of causing scales of single-injection water or mixed-injection water in a certain gas field of China was predicted. Evidently, the CaCO 3, MgCO 3 and BaCO 3 scale could be produced in single-injection water system, and BaSO 4 scale in mix
