含凝析油气井试油方法探索

含凝析油的气井流体相态变化复杂,导致试油难度增大,提高凝析气藏中凝析油采收率是开发追求的主要目标之一。采取适当的试油方法,搞清地层是否存在凝析油尤为重要。通过对含凝析油的气井试油方法探讨,认为此类井应该放大油嘴降低流压求产,确保凝析油产出。经过实际验证,方法可行。

Exploration of Oil Testing Method in Natural Gas Well with Condensate Oil

Change of fluid phase is complex in natural gas well with condensate oil,which causes the bigger of oil test difficult.Increasing condensate oil recovery in gas condensate reservoir is one of the main aims of development.Taking appropriate oil test method,finding out the existence of condensate formation is particularly important.By discussion on the content of condensate oil gas well testing method,it is thought that for this kind of well,nozzle sizes should be enlarged to reduce flow pressure for production to ensure producing the condensate oil.The method is feasible by the actual test.
