摘要
影响高温高压井固井质量的问题很复杂,其中水泥浆选型和防气窜在高温高压固井作业中起着重要作用。为提高高温高压固井质量,必须全面研究高温高压固井中所遇到的问题,并提出解决的办法;要确立和完善高温高压固井新概念,增加高温高压固井的成功率和可靠性,抓住矛盾的主要方面,建立一套有效的防气窜工艺程序。通过对南海西部莺琼海域大气区的固井实践的总结,建立了对高温高压固井的新认识。
The effects on the cementing job in high temperature/high pressure (HTHP) wells are complicated. Cement slurry types and gas migration are major concerns among all. Gas migration is in close relationship with cement slurry type. Both play an important roll in the performance of HTHP cementing. In order to improve cementing performance, it is necessary to study all the problems encountered during HTHP cementing and obtain some solutions. To establish new cementing concept and increase success and reliability, the key is to form a technique process of preventing gas migration.
