一、浅层气勘探概述用岩心钻探设备勘探浅层天然气资源是岩心钻探工作的新内容。近年来,随着国民经济建设及人民生活的需要,天然气的需求量日益增大,供需矛盾愈加突出,浅层气(含煤成气)的勘探、开发利用已越来越引起有关部门重视。到目前为止,全国已多家勘探单位开展了这项工作,取得了一定的成效。在能源十分紧张的今天,如何利用岩心钻探设备多快好省地开发我国的浅层气资源,是摆在我们岩心钻探技术工作者面前的重要课题。用岩心钻探设备施工浅层气井具有成本低、占地少、周期短、搬迁方便等特点,是石油钻井设备所无法相比的。据统计,用陆地石油钻井设备施工浅层气井,其成本约是地质钻探 I. Overview of Shallow Gas Exploration Exploration of shallow gas resources with core drilling equipment is a new content of core drilling. In recent years, with the needs of national economy construction and people’s life, the demand for natural gas has been increasing day by day, and the contradiction between supply and demand has become more prominent. The exploration, development and utilization of shallow gas (coal-bearing gas) have drawn more and more attention from relevant departments. So far, many exploration units across the country have carried out this work and achieved some success. In today’s energy-intensive society, how to use the core drilling equipment to develop the shallow gas resources in China more quickly and economically is an important issue before our core drilling technology workers. The construction of shallow gas wells with core drilling equipment has the characteristics of low cost, less land occupation, short cycle and convenient relocation, which is unmatched by oil drilling equipment. According to statistics, the shallow gas wells are constructed with land oil drilling equipment, the cost of which is about geological drilling
