Reserach On Characteristics And Three-Dimension Geologic Model Building Of The Chang2 Reservoir,Yanchang Formation In Zhifang Area, Zhidan Oilfield

摘要

Through the reservoir of Chang 2 member in Zhifang area, Zhidan oilfield is typical of low porosity and low permeability reservoir rocks, using casting thin sections, scanning electron microscopy and physical analysis, etc., starting with the reservoir characteristics of Chang2 member, we have understood its causes and characteristics of low permeability. Using sequential indicator simulation and based on the target body method, we established the head of the construction of the reservoir model in Chang 2 member, using the sequential Gaussian simulation method combined with phase control principle, a model of reservoir properties in this area was established. Getting a high quality reservoir and field development and deployment of later development and further adjustments to tap the potential pratical guidance.
