Open publisher page 0 citations

Abstract

Aiming at the problems in the process of the stabilized well test of gas condensate wells with high condensate content,the flexibility of stabilized test in this kind of wells is analyzed based on the withdrawal characteristics of gas condensate reservoirs.A well test method adapted to gas condensate wells with high condensate content is put forward,which takes the well production characteristics into consideration.The field conduct of the method shows that the modified isochronal testing method can eliminate the effects of retrograde condensation on test results and obtain precise testing results,providing the foundation for reasonable production proration.
