摘要
老井挖潜是油气藏开发中增储上产、增收节支、提高气藏采收率的重要举措,在国内外各类油气田开发中均得到广泛开展。但各类油气藏因地质特性差异,老井挖潜措施及手段各异。川西致密碎屑岩气藏作为勘探开发难度极大的非常规气藏,老井挖潜在气藏开发中的措施和手段也具独特性。通过老井挖潜在该气藏开发实践中的应用分析,对其形成的具针对性的挖潜配套工艺技术体系,进行了认真分析、研究和评价,可指导国内外类似气藏制定合理的开发技术方案和对策,具积极的参考价值。
Re entry the old well is the important act of increasing output, retrenching expense and increasing the recovery ratio, it is applied in many oil and gas field of worldwide As the geological difference, the measure and method of re entry the old well are different and particular. As the un-conventionality gas reservoir, the densify elasolite gas reservoir in West Sichuan has the world- class diⅠculty in E &P. According to analyze the exploitation application, this paper summarizes the professional technical system of re - entry the old gas well, which is helpful for establishing the rational exploitation project of similar gas reservoirs.
