Coalbed gas, or coalbed methane (CBM), is a new natural gas resource that has come to the industry's attention just recently. Unlike trap-dependent conventional natural gas, CBM is preserved by adsorption to the internal surfaces of micro-pores and fractures in coalseams, which serve as both...
在页岩储集层段,中子孔隙度值显示低值,这代表高的含气量、短链碳氢化合物。 5. 地层密度测井: 页岩密度为低值,随着有机质和烃类气体含量增加将会使地层密度值更低。存在裂缝,也会使地层密度测井值降低。 6. 岩性密度测井: 岩性密度测井可应用于识别页岩粘土矿物类型。页岩矿物组成的变化,将导致单位体积页岩岩性...
China produced 17.1 billion cubic meters (BCM) of methane sourced from coal seams in 2015, of which 4.43 BCM is from wells drilled from the surface. This level of production is a clear indicator that China has gone into early stage large-scale coalbed methane (CBM) development. CBM resources...
It is for audiences: this book will be an important source of information for geologists and petroleum geologists, geochemists, and fossil fuel engineers, as well as regulators. It is also of interest for graduate students in geology and mining. Coalbed Methane 2024 pdf epub mobi 电子书 ...
coalbed gas to liquid natural gas projects supplying the demand for cleaner burning LNG to the Asian-Pacific region. Since the last edition of this book, global climate change policies have more forcibly emphasized the impact of methane from coal mines and placed these emissions equal to, or ...

Coalbed methane is considered to be one of the major contributors to global warming. Geological prospecting of the rich-storage zone of methane is an impor
A physical property boundary occurs when a coal body is recrystallized into mylonitic coal by the action of tectonic stress, and its physical properties degrade and the displacement pressure increases remarkably. As a result, the diffusion and migration of coalbed methane is blocked. Also, mylonitic...
Coalbed methane has been explored in many basins worldwide for 30 years, and has been developed commercially in some of the basins. Many researchers have described the characteristics of coalbed methane geology and technology systematically. According to these investigations, a coalbed methane reservoir...
