自2006年以来,在沁水盆地南部潘庄区块共实施了80多口多分支水平井,本文选取同一区域内的6口典型多分支水平井作为实例开展研究。分析了煤的厚度、含气量、储层压力、渗透率、埋藏深度等储层条件。结果表明:含气量、储层压力和渗透率是影响煤层气采收率的关键因素。潘庄区块分支水平井的气产曲线特征受资源丰度、储层压力和渗透率控制。实际生产数据和产能模拟数据表明,潘庄区块多分支水平井的产气曲线具有早期峰值高、峰值周期长的特点。

Abstract:

Natural gas hydrate is an ice-like substance which is sometimes called “combustible ice” since it can literally be lighted on fire and burned as fuel. Natural gas hydrate is characterized by widespread distribution, large reserves and little pollution. This paper introduced the distributions of hydrate, hydrate reserves and properties of hydrate. The main exploration methods, such as geophysical exploration and geochemical exploration have been presented. In addition, the main production techniques of natural gas hydrate including depressurization, thermal stimulation and chemical injection have been summed up. Finally, the challenges and outlooks of natural gas hydrate production have been proposed.



Keywords: Gas hydrate, property of natural gas hydrate, exploration methods, production methods.
