现在,随着全球对环境保护的日益重视,天然气需求量将迅速上升。据专家预测,到2015年,世界天然气产量将超过石油产量成为第一能源,天然气将占世界能源的29%。煤层气俗称“煤矿瓦斯”是与煤伴生、以吸附状态储存于煤层内的一种非常规天然气,其成分与常规天然气大致相同,CH4含量超过95%,热值在33.44kj/m3以上,是一种优质清洁的气体能源。煤层气如不开发利用,危害极大。针对新兴起的煤层气开采产业,设计开发新型的抽油机以适应开采的需求,拓宽抽油机的应用领域。
Now, with the global emphasis on environmental protection, natural gas demand will rise rapidly. According to experts, by 2015, the world’s natural gas production will exceed the oil output to become the first energy source, while natural gas will account for 29% of the world’s energy resources. Commonly known as CBM “CMM ” is an unconventional natural gas associated with coal and stored in the coal seam in an adsorbed state. Its composition is about the same as that of conventional natural gas. The CH4 content exceeds 95% and the calorific value is above 33.44 kj / m3 , Is a kind of high quality and clean gas energy. If CBM is not exploited, it will be very harmful. For the emerging CBM mining industry, the design and development of new type of pumping unit to meet the needs of the exploitation, broaden the application of pumping unit.
