Quantitative characterizati0n of interlayer heterogeneity of reef flat reservoir
Online published: 2013-10-08
Reef flat reservoir is often in fluenced by diagenesis and tectonism，which leads to the extremely strong heterogeneity．Therefore，quantitative characterization of the heterogeneity can effectively guide the reservoir prediction and oil·gas field development．Taking the reef flat reservoir of Pugu ang Gas Field as an example，we selected aggregate index method and permeability diversity coeficient method to characterize the interlayer heterogeneity The result shows that the two methods have consistency in the assessment result，and the assessment result is consistent with geological cognition．The two methods can not only solve the uncertainly problem of single parameter characterization， but also avoid the impact of unbounded parameters．The methods can realize the quantitative characterization of reservoir
heterogeneity，and truly reflect the reef flat reservoir characteristic of stronger heterogeneity，which provides reference for similar research．
