摘要:
由于储层多孔介质界面现象的存在,采用类似干气的传统物质平衡方法来计算凝析气藏的储量并预测其产量必然与实际的储量和产量存在差异。基于相平衡计算模型建立了考虑吸附和毛管压力影响的凝析气藏物质平衡方程,利用该方程可以准确计算凝析气藏的储量并预测其产量。将该方法运用于实际凝析气藏中,结果表明该方法所计算的储量和预测的产量均小于传统物质平衡方法和不考虑吸附和毛管压力影响的物质平衡方法所计算的结果,且与现场实际结果更为匹配。该研究对于凝析气藏的开发具有指导意义。
Abstract:
During the process of the development of gas condensate reservoir, the gas-liquid two phases have formed due to the appearance of condensate oil along with the decrease of formation pressure. Because of the existence of adsorption and capillary pressure, there is a large difference in material balance equation between the traditional gas reservoir and gas condensate reservoir. This paper sets up the material balance equation of gas condensate reservoir, which considers the affection of adsorption and capillary pressure, to calculate the reserves and predict yield of gas condensate reservoir. The result shows that the reserves and predicted yield calculated by the method are smaller than that are calculated by traditional material balance method and material balance method without considering the impact of adsorption and capillary pressure, and it is more matching with the actuality. With the increase of the condensate content, the difference between three methods of calculation will increase. It is instructive to the development of gas condensate reservoir.
