摘要/Abstract

摘要： 针对常规气藏产能方程难以准确评价裂缝-孔隙型碳酸盐岩气藏产能的问题,利用Kazemi模型简化裂缝-孔隙型碳酸盐岩气藏渗流模型,根据气体在裂缝与基质层中的不同流动状态,将双重介质复杂渗流分解为基质层线性渗流与水平裂缝径向渗流,建立了综合考虑裂缝渗透率、裂缝开度、裂缝条数及窜流系数的裂缝-孔隙型碳酸盐岩气藏稳态产能方程,开展气井产能敏感性分析研究。结果表明:气井无阻流量随着裂缝渗透率、开度及条数的增加而增大,且两者呈正向线性关系;随着窜流系数不断增加,气井无阻流量也不断增大,当窜流系数大于5×10^-9时,气井无阻流量基本无变化。该研究为裂缝-孔隙型碳酸盐岩气藏稳态产能预测提供了新的解决思路。

Abstract: Since conventional gas reservoir productivity equation is difficult to accurately evaluate the productivity of fractured-porous carbonate gas reservoirs, Kazemi model was adopted to simplify the seepage model of fractured-porous carbonate gas reservoirs, the dual-medium complex seepage was decomposed into the linear seepage in substrate layer and the radial seepage in horizontal fractures according to the different flow states of gas in fracture and substrate layer, the steady productivity equation of fractured-porous carbonate gas reservoirs was established with consideration of fracture permeability, fracture opening, fracture number and channeling coefficient, and the productivity sensitivity of gas wells was analyzed. The results showed that the open-flow capacity increased with the increase in the permeability, openness and number of fractures, presenting a positive linear relationship; the open-flow capacity of gas wells increased with the increasing channeling coefficient, and remained unchanged when the channeling coefficient was greater than 5×10^-9. This study provides a new solution for steady productivity prediction of fractured-porous carbonate gas reservoirs.

Key words: fractured-porous, productivity evaluation, Kazemi model, stable productivity, fracture opening, channeling coefficient
