气井环空带压安全状况评价方法研究
Research of Evaluation Method of Safety Condition of SCP in Gas Well
摘要
Abstract
With the development of natural gas industry, more and more HPHT and high hydrogen sulfide-bearing well have been built. About 25% of wells of the global turn up SCP more or less. An increasing number of air pressure phenomena exiting in the annulus between tubing and casing, as well as casing and technical casing, have been an important problem that impact production safety. It has been realized that SCP of the gas well in high pressure may lead to huge damage, but the reason, effect factor and measures of remediation about SCP have never been put in depth study interiorly. Therefore, a model of SCP has been built, and at the same time corresponding safety situation evaluation method and process has been provided, based on a present situation investigation and statistic analysis about SCP in field at home and abroad. Thus, it can provide basis for formulating the corresponding measures of safety management for SCP.关键词
