| 摘 要： | 鄂尔多斯延川南地区发育低渗、多层煤层气藏,主力煤层为2号和10号煤层,分层压裂合排采气（以下简称分压合采）是制定开发规划时的首选方案之一。基于延川南地区煤层气井的实际生产资料,并结合煤层气井的产气特点,论述了延川南地区2号和10号煤层分压合采的影响因素及可行性,研究认为,煤层压力与压力梯度、解吸能力、层间距、上下围岩岩石性质、水文地质条件、原始渗透率及压裂后渗透率等是分压合采提高煤层气井产能的控制条件。最终,提出了该地区2号和10号煤层分压合采适合基本地质条件,优选了有利区域。

| Abstract: | The low-permeability and multi-layered CBM reservoirs that developed in Yanchuannan area of Ordos,have the main coal seams of NO.2 and NO.10.Layered fracture and commingled water drainage & gas production(hereafter abbreviated as layered fracture and commingled production) is one of the preferred strategies for development projects.Based on the production data of CBM wells in Yanchuannan area,and combined with the gas production characteristics of CBM wells,this paper discussed the in fluencing factors and ... |
