In order to evaluate coal bed methane (CBM) reservoirs, this paper select five parameters:
porosity, permeability, CBM content, the coal structure index and effective thickness of the …

沁水盆地安泽区块煤层形成后经历多期构造运动, 致使煤体结构遭受不同程度的破坏,
煤体结构的分布规律制约本区煤层气的开发. 基于此, 利用该区的测井资料 …

This paper summarises the response characteristics of electrical microresistivity image
logging on different coal seam structures through systemic pectination from Qinshui Basin in …

Density logging is an effective method in the evaluation of coalbed methane (CBM)
reservoirs. Whether density log values effectively represent true density of coal will directly …

This paper presents an innovative solution for estimating the proximate parameters of coal
beds from the well-logs. To implement the solution, the C# programming language was …

Anze block of Qinshui basin has experienced several tectonic events since coal-forming
period, resulting in the destruction of coal structure at different degrees, the exploitation of …

Petrophysical analysis of inverted well logs includes the identification of bed boundaries and
associated bed thickness values, for which it is convenient to define one set of boundaries …

Coal structure, which is important for the mining of CBM, is closely related to the coal
reservoir fracture characteristics. This paper calculates the integrity coefficient, stability …

Density, photoelectric, neutron, and gamma ray logs are key inputs to the evaluation of
unconventional resources. Each has a finite spatial resolution, and the properties of beds …
