摘要: 凝析气藏合理开发井距确定一般用经验值给定。在雅克拉凝析气藏开发方案制定中, 用两种方法确定了合理开发井距:一是以油藏数模为手段, 充分考虑地下产生反凝析油的特点, 结合井网密度和凝析油采收率的关系, 确定合理开发井距为1 200 m;二是通过气价、凝析油价与钻井油建费、操作费的平衡, 计算出单井控制经济极限储量,确定最小合理开发井距为1 079 m.上述两种方法实用、简便、可靠。

Abstract: Reasonable developing well spacing for condensate gas reservoir is usually determined by empirical value. During working out development project in Yakela condensate gas reservoir, two methods were used to determine it:①based on retrograde condensation characteristics of reservoirs, combining well spacing with oil recovery, reasonable developing well spacing of 1 200 m was determined with reservoir numerical simulation.② based on balance between gas and condensate oil price and oilfield construction and drilling cost, the least reasonable developing well spacing of 1 079 m was determined by calculating recoverable reserve of single well at economic limit.These methods are practical, simple and reliable.
