Fluid Phase State Reconstruction for Complex Block Gas Condensate Reservoir with Oil Ring
复杂断块带油环凝析气藏流体相态重构

For the early development of gas condensate reservoir,especially the reservoir with oil ring,precise characteristics of formation fluid phase are essential to deploy development plan and select producing method.Yet the,representative PVT samples may not be obtained in the early development period due to various reasons,and this affects the accuracy of design and forecast of gas reservoir development program.Here we introduce the fluid phase reconstruction method to get accurate fluid phase characteristics based on component gradient and phase balance theories.Precise fluid components and its phase model can be obtained by use of multi\|fluid reconstruction,flash and parameters matching on considering fluid composition and characteristics discrepancy in vertical direction.This study is a very good guide on the early fluid phase study and its development plan designing for gas condensate reservoir with oil ring.
