摘要
从高温高压井的概念出发,阐述高温高压气井固井中存在的主要问题,分析影响固井质量的因素,由此提出了提高固井质量的途径与方法;重点介绍采用套管外封隔器提高固井质量的作用机制;最后针对高温高压气井提出用常规套管封隔器存在的问题及解决该问题的初步设想。
In this paper, the concept of HTHP gas well is given, the main questions of cementing in HTHP gas well are described, the factors of infecting cementing are analyzed from the mechanism and the solving method of improving the effect are presented. The mechanism of improving cementing quality is introduced using the outer casing pecker. In the end, the questions and the design philosophy solving the question using the normal outer casing pecker in HTHP gas well are present.
