重庆气矿飞仙关气藏高酸性气井完井试气工艺技术的研究与应用

高酸性气井完井直接关系着气井的质量、寿命和完井、试气及采气作业员工的安全,是气井安全、高效生产的基础。针对重庆气矿飞仙关高酸性气田的地质现状以及高酸性介质给气井的完井投产所造成的严重困难,认真研究并提出了重庆气矿飞仙关气藏高酸性气井完井试气的工艺技术方案。通过峰15等井的现场工艺成功试验,为今后重庆气矿飞仙关高酸性气井的完井投产探索了一条路子,并对该地区高酸性气藏规模开发提供了技术决策依据。

Research and Its Application on Well-completion and Gas-well Testing Technology in High Sulfur Gas Wells in Feixianguan Gas Reservoir in Chongqing Gas Field

The well completion in high - sulfur gas wells is relation to the quality, lifetime of the gas well and the safety of the well completion, well testing and gas production operators, and it is the basis of safety of gas well and production with high benefit. Aimed at the geological status of high sulfur gas wells in Feixianguan gas reservoir in Chongqing and the serious difficulties of well completion production in gas well produced by high sulfur medium, this paper researches and points out the technique project of well completion and gas well testing in high sulfur gas wells in Feixianguan gas reservoir of Chongqing gas filed. Through the successful technique experiment of Well Feng 15, this project explores a new way for well completion production in high sulfur gas wells in Feixianguan gas reservoir of Chongqing gas filed, and it offers the technique basis for the scale production of high sulfurgas reservoir in that area
