煤层气属于非常规的天然气资源。过去,开采煤气层主要通过地面直井排水降压方法,单井产量偏低,经济效益不理想。随着技术水平的不断发展与完善,现代水平井钻井技术应运而生,既增加了产量,又可降低成本,具有良好的应用价值。本文将深入分析我国当前煤层气的开发现状,并对现代水平井钻井技术及其具体应用进行分析与阐述,推动现代水平井钻井技术的普及与推广。
CBM belongs to unconventional natural gas resources. In the past, the method of draining and depressurizing the direct gas wells through the ground was mainly used to mine the gas layer. The output of a single well was low and the economic benefit was not satisfactory. With the constant development and improvement of the technical level, the modern horizontal well drilling technology came into being, which not only increases the output but also reduces the cost and has good application value. This article will deeply analyze the current development of CBM in our country, analyze and expound the modern horizontal well drilling technology and its specific application, and promote the popularization and promotion of modern horizontal well drilling technology.
