柳林地区煤层气排采控制因素及改进措施

Control Factors and Improvement Measures for Liulin Block Coalbed Methane Drainage

我国煤层气总体具有低压、低孔、低渗、低产的特点,这给煤层气排采工艺技术带来了很大的困难与挑战。柳林区块作为中联煤层气有限责任公司建产的主力区块,地质条件复杂,开采难度较大,因此,有必要加强该区煤层气排采规律的研究,制订科学、合理的定量化排采工作制度,实现稳产并提高单井产量。

Coalbed methane in China also features low pressure, low porosity, low permeability and low yield in general, which bring much difficulty and challenge for coalbed methane drainage technology. As major block built by China United Coalbed Methane Co. , Ltd. , Liulin Block features complicated geo- logical conditions and large exploitation difficulty, so, it is necessary to strengthen study on coalbed methane drainage regularity at this area and formulate scientific and reasonable quantified drainage work- ing system to realize stable yield and boost single -well production.
