摘要

为探究凝析气藏衰竭式开发效果的影响因素,选取塔里木盆地某区块凝析气藏为研究对象,通过对碳酸盐岩岩心人工造洞,开展不同降压速度、不同缝洞位置的凝析油和天然气采收率实验,分析气油比及采出气组分的变化规律。实验结果表明:降压速度与凝析油采收率、天然气采收率正相关;缝洞在目的层上部时采收率最大,在侧部时次之,在下部时采收率最小;气油比呈现先降低后升高的趋势,碳酸盐岩缝洞孔隙结构会造成凝析气体系露点压力上升;采出气中甲烷含量与凝析油采收率负相关。研究成果对缝洞型凝析气藏的开发方式选取和提高开采效果具有重要的指导意义。

Abstract

In order to investigate the influencing factors of the natural depletion effect of condensate gas reservoirs, a block of condensate gas reservoirs in Tarim Basin was selected as the study object, and experiments on the recovery efficiency of gas condensate and natural gas with different depressurizing rates and different fracture-vug locations were performed through artificial holes made in carbonate cores to analyze the changes in the gas-oil ratio and the components of produced gas. The experimental results showed that, the depressurizing rate was positively correlated with the recovery efficiency of gas condensate and natural gas; the recovery efficiency was the largest when the fracture-cavity was in the upper position of the target layer, the second in the lateral position, and the smallest in the lower position; the gas-oil ratio presented a trend of first decreasing and then increasing, and the pores of the carbonate fracture and vug caused the dew point pressure of the condensate system to rise; the methane content in the recovered gas was negatively correlated with the recovery efficiency of gas condensate. The study results are of important significance for guiding the selection of development methods of fractured-vuggy condensate gas reservoirs and the improvement of production effect.

Key words： gas condensate reservoir; dew-point pressure; depletion-drive development; long core; depressurizing rate; fracture-vug location
