摘要
方法利用数值模拟方法和单井控制经济极限储量分析法，确定凝析气田的合理开发井距。目的为凝析气田的开发井网部署提供依据。结果经同一凝析气田应用，两种方法计算结果可靠，既提高了凝析油采收率，又增加了其经济效益。结论在实际工作中，两种方法可结合起来确定合理井距；但对于面积很大，要求开发井数十分少的凝析气田，不适用数模方法确定合理井距，这种情况只要将开发井均匀地布在气田上即可。
Method The rational well spacing of condensate gas reservoir is determined by usingnumerical simulation and analysis of limiting reserve controlled by single well. Purpose Toprovide basis for developing condensate gas reservoir and pattern arrangement. Result After application in a same condesate gas reservoir, it is proved that the calculation results ofthese two methods are reliable. Both the recovery factor of condensate and the economic benefit are improved. Conclusion in practical work, the rational well spacing can be determinedby comprehensively using these two methods. For those large condensate gas reservoirswhich need a few number of development wells, numerical simulation is not suitable for determining rational well spacing. In this situation, evenly arranging development wells on gasfield will be effective.
