某煤层气井田位于焦作矿区,面积79Km2。近年来河南某公司先后对该井田二十多口煤层气井进行不同类型的压裂改造,但压裂效果不明显,单井气产量普遍较低。本文通过对该井田内煤层结构、性质以及采用的压裂工艺、排采工艺进行研究,分析了造成该井田低产的几个主要原因,为以后煤层气井压裂改造提供帮助。

A CBM well field is located in Jiaozuo mine area, covering an area of 79Km2. In the recent years a Company in Henan has made different types of stimulation treatment to more than twenty CBM wells. Howev- er, the results are not evident. The single well production of CBM well is universally low. The paper has stud- ied the tectonic structures in the coal seams in the well field and their characters, the stimulation and dewater- ing and drainage technologies applied. The paper analyzes the main masons for low yield of the wells, which provides assistance for future stimulation treatment of the CBM wells.
