摘要
储量是一个气田开发的物质基础,准确地评价动储量是确定气田生产规模、预测生产动态以及评价开发潜力的基础。低渗气藏具有渗透率较低、压力恢复缓慢、测压成本较高等特点,针对以上问题,通过利用气井生产资料,将气井的压力、流量生产数据转换为拟等效的恒压力、恒流量,在常规压降法的基础上,形成产量不稳定分析法、采气曲线法等气井动储量评价方法,非常切合低渗气藏的生产实际。
Reserves are the basis of gas field development,the accurate dynamic reserves evaluation is the basic to determine reasonable production scale of gas field to carry out the production dynamic prediction and to evaluate development potential.Due to the low permeability,slow pressure recovering and high cost to test the formation pressure,it tries the approaches of reconstructing pressure and flow to change the production data of variable pressure or production rate into equivalent constant pressure or production rate,and developed the Rate Transient Analysis method,and Gas recovery curve method and those methods are very appropriate for the low permeability gas field.
