摘要
沁水盆地部分煤层气井的单井产量低,且低产井所占比例较高,如何提高低产井的产能是目前急需解决的问题。本文就脉冲功率技术的技术原理、作用效果、技术特点、适用范围等方面进行了深入分析,在此基础上从作用范围、固井质量、井深要求、地面环境等方面详细论证了用于低产煤层气井增产的可行性,并提出了开展现场实施应用的建议。
The production of a single well is low in part of CBM wells in Qinshui Basin, and the percentage of low production wells is also high in this area. Currently, how to enhance the production capacity of these low production wells is a problem to be resolved urgently. The paper has made a to-the-depth investigation in many aspects, such as, the technical principles of pulse technique, its effect and results, technical characteristics, and scope of application, etc. Based on the analysis, the feasibility of enhancing production of these low production wells is authenticated in details in aspects, sach as action range, quality of cementation, required well depth, surface environment, etc., and recommendations on site application are proposed.
