Abstract

Abstract:

The oil pool of Sha 2 member in the east part of Pucheng Oilfield is a multi layer heterogenous bedded oil pool,and has entered into high aquiferous exploration stage.The remaining reserve of the pool is 396?10⁴t,mainly distributed near faults,in the higher parts of structures and complicated fault blocks.Micro structures and reservoir property are the basic factors influencing the distribution of remaining oil;normal micro structures and micro roof type structures are the positions for oil enrichment;the fluid flow unit with lower permeablity has higher remaining oil saturation.Besides,the saturation increases with the increasing of waterflood well spaces.

Key words: remaining oil, micro structure, sedimentary microfacies, water flood recovery system,Pucheng Oilfield
