确定气井合理产量和预测新井产能方法研究

Study on the Methods for Defermining Gas Well Reasonable Output and Froecasting New Well Productivity

本文从川东大天池构造带石炭系气藏开发概念设计实际需要出发,对川东地区石炭系气藏的气井合理产量和新井产能进行了分析研究,得出了气井合理产量与无阻流量的函数关系和地层系数与无阻流量的函数关系式,从而较好地解决了定量确定气井合理产量和预测新井产能的问题。

Starting from the actual need of conceptual design of Carboniferous gas development in Datianchi structure belt in East Sichuan, this paper analyses and studies the gas well reasonable output and the new well productivity in this area, and the fuction relational expression between gas well reasonable output and open flow capacity and that of between stratum coefficient and open flow capacity are ob- tained, thus the problems of quantitatively determining gas well reasonable output and forecasting new well productivity can be solved.
