| 摘 要： | 通过试验和理论相结合的方法建立了考虑科林贝尔效应的低渗透气藏非线性渗流方程。通过渗流流量和压力相关试验测定了滑脱修正系数和渗流指数以及渗流系数,并将该方程的计算结果和现场产量做了对比,证明了该方法的正确性。气体渗流存在着滑脱效应,特别是在低渗、低速和低压时,滑脱效应更为显著。该项研究成功实现了对低渗透气藏的产量动态预报,为低渗透气田开发设计和开采方案优化提供了一项强有力的技术手段,为进一步开展低渗透气藏渗流理论研究、油藏工程研究和动态分析建立了基础。

| Abstract: | Based on percolation mechanism analysis of low permeability gas reservoirs,combined the effect of Klinkenberg,established non-linear percolation mathematical model.Measured coefficient of slippage,seepage index and seepage coefficient by experiment,and compared calculated results with spot results and verified the effectiveness of this method.Slippage effect exists in porous media flow,especially when pressure,velocity or permeability,it is very obvious,also gas flow equation in porous media with a slippage effect was presented.This research has provide a strong technical support for the optimization of development plans and recovery schemes. |

| Keywords: | low permeability gas reservoir seepage index modified coefficient of slippage seepage coefficient permeability |
