根据试气工作时的实际情况发现,在工作量不断增多的同时,试气过程中遇到的各种事故也在增多。试气过程中常见的井下事故主要分为管柱遇卡及井内落物两大类。根据所遵守的处理事故的原则,根据遇到的不同情况,对气井进行解卡作业。提出了使用质量较好的防砂井下工具,防喷过程中严格控制出砂,在压力高时严禁无控制防喷,起下管柱过程中使用自封等七项措施。这些措施对于减少试气事故的发生具有一定意义。
According to the actual situation during the test gas work, it is found that while the workload is constantly increasing, various accidents encountered during the test gas are also increasing. The common underground accidents in the process of gas testing are mainly divided into two major categories of pipe pillars and stuck objects inside the well. According to the principle of handling accidents, according to the different situations encountered, the gas wells card operations. Proposed the use of good quality sand control downhole tools, blowout control in the process of strict control of sand, high pressure is prohibited without control blowout, from the use of self-styled during the lower seven measures. These measures are of some significance for reducing the occurrence of gas test accidents.
