摘要
垂直煤层气井,必须要实施增产措施才可能达到我们所需要的生产气流。煤层气井的增产措施主要有两种,即井底煤层造穴和压裂。其中井底造穴的洞穴直径要达到多大,才对煤层气的产出有效,是我们迫切需要了解的问题。本文设定除井径以外的参量为已知数,取井径为自变量,计算出因变量煤层气产出量的值,并寻找出煤层气的产出量与井径的函数表达式。
Measures to increase the gas production should be implemented in CBM vertical wells in order to gain the productive gas we need. There are mainly two measures, cavitation in CBM well bottom and fracture. What we urgently need to know is the measure of a cave in diameter that can be effective to the CBM production. This paper, setting the parameters except the borehole diameter as known quantities, and the borehole diameter as an independent variable, work out the value of the dependent variable, the CBM production. It also finds out a function expression of the CBM production and the berehole diameter.
