In The Middle-eastern Of Saertu Transitional Injection Production System Adjustment In Practice And Understandding

Saertu middle-east river deltas deposited in the transition zone is a multi-reservoir sandstone reservoir,the reservoir is a transitional siltstone,shale and siltstone,silty mudstone and siltstone calcium deposition,reservoir development is more complex,porosity,permeability,oil saturation is low,serious heterogeneity.Saertu middle-eastern transition zone than the current high number of oil wells,while playing with his four secondary infill wells,take delineation wells rolling development approach,well after the completion of the second fabric infill wells,the need for the four band edge perform system adjustment,improve injection relationships.Due to imperfect relationship between.injection middle-eastern transition zone of low-yielding low note" very serious,very serious phenomenon casing damage.In this paper,the saertu middle-eastern basic well in transition and primary and secondary infill wells corresponding net perforation rate,the more prominent contradiction between layers,thin and poor utilization of oil and table outside the reservoir is poor,especially in the four regions with the number of oil wells than high,injection systems are imperfect and other issues,on the eastern transition to injection system be adjusted to the center of comprehensive management,improve the relationship between injection and adjustment around the injection system,to carry out comprehensive management,and strive to improve low by the effect of poor reservoir development and penetration of thin sheet to achieve succeed reservoir yield,improve the development effect adjustment area.
