东海凝析气井合理产能的确定

Confirming the rational productivity of gas-condensate wells in the East China Sea

凝析气井合理产能的确定对凝析气藏的合理开发具有重要的指导意义。在认识东海凝析气藏的基础上,总结了当前利用测试资料求取凝析气井绝对无阻流量的各种方法,给出了公式推导过程;同时给出了确定合理产能的原则与方法。结合东海凝析气井的测试实例,运用确定凝析气井合理产能的方法,获得该井的合理产能。通过产能试井结果对该井配产进行了调整,获得较好的实际效果。

Confirming the rational productivity of gas-condensate wells has great guiding significance in rational development for gas-condensate reservoir. Based on knowledge of gas-condensate reservoir in the East China Sea, this paper summarizes the methods of getting absolute open flow of gas-condensate well, performs mathematical calculation, and gives principal methods of confirming rational productivity. With testing example of gas-condensate well in the East China Sea, using the method of confirming rational productivity of gas-condensate well, rational productivity of the well has been acquired. Production allocation is adjusted using the result of productivity testing. Good practice result has been acquired.
