First, the instantaneous point-source solution of pseudo-pressure for anisotropic gas reservoir is derived. Then the instantaneous source function method and Newman multiplication principle are applied to give the Green's function for various multi-branched horizonal wells in gas reservior. 对分支水平井各向异性地层,导出气藏拟压力的瞬时点源解,利用瞬时源函数和Newman乘积原理,给出气藏中各种分支水平井的Green函数。
The structure of BES μ-counter module is described. The measurement results of wire tension, gas tightness, O2 content, dark current, counting-rate plateau curve and gas multiplication of the module are reported. 文中描述了北京谱仪μ计数器组件的结构,报道了张力、气密性、杂质氧含量、暗电流、计数率坪曲线和气体放大特性的测量结果。
