新疆准南地区煤层气井低产原因与增产措施研究

Research on the Reasons for Low Production of Coalbed Methane Wells and Measures for Increasing Production in Zhunnan Area of Xinjiang

煤层气是非常规天然气的一种,开采煤层气不仅有利于保障煤矿抽采安全,还是民用天然气的一种有利补充。新疆煤层气资源丰富,但地质条件复杂,煤层气井产量两极分化严重,尤其是低产井占比极高,这就导致了煤层气井投入与产出不成正比,严重制约了煤层气产业的发展。本文以新疆准南地区煤层气区块为例,全面分析了煤层气井高产、低产因素,并针对性的提出了有效的增产措施,为新疆煤层气低产井增产改造提供借鉴。

Coalbed methane is a type of unconventional natural gas.The development of coalbed methane is not only beneficial for ensuring the safety of coal mines but also a beneficial supplement to civilian natural gas.Xinjiang is rich in coalbed methane resources,but its geological conditions are complex,and the production of coalbed methane wells is severely polarized,especially with a high proportion of lowproduction wells.This leads to a disproportionate investment and output of coalbed methane wells,seriously restricting the development of the coalbed methane industry.This article takes the coalbed methane block in the Zhunnan Area of Xinjiang as an example to comprehensively analyze the high and low production factors of coalbed methane wells and proposes effective stimulation measures,providing a reference for the stimulation and transformation of low-production coalbed methane wells in Xinjiang.
