反映煤储层渗透性的参数之一——块煤率

One of parameters reflecting coal reservoir permeability——block coal rate

  • 摘要: 煤储层的渗透性在很大程度上取决于煤体结构,煤体的整体结构决定煤炭筛分试验所获得的块煤率,所以块煤率可以从整体上反映煤储层的渗透性。辽中地区几个矿区煤储层块煤率与渗透率有很好的相关性,为块煤率作为评价煤储层的参数之一,提供了一个实例。

     

    Abstract: The permeability of reservoir depends on coal body texture to a great extent.Coal body tecture directly relatives to block coal tate got from sieve experiment so block coal rate can feflect coal reservoir's permeability as a whole.In mining areas in the middle part of Liaoning,block coal tate has a direct relationship to permeability.This is a instance that block coal tate regards as one of parameters evaluating coal reservoir.
