摘要
本文介绍一种低饱和度油层动态评价方法,根据低饱和度油层开采动态特征,结合地质、油藏等多种学科,明确低饱和度油藏成因;通过束缚水饱和度、渗透率、区域原油性质等资料建立基于相对渗透率与原油粘度的储层含水率计算模型,结合储层静态资料定量计算储层动态开采初期含水率,形成动静态结合的储层流体识别方法,精准识别蠡县斜坡低饱和度油层,提高了区域解释符合率;同时,根据储层产液量、原油密度、储层渗透率建立基于两相渗流的产能预测模型,估算储层产能,与区域试油、投产结果符合率较高,为区域储层增储上产提供新的技术支撑,效果显著。
The article introduces a dynamic evaluation method of low-saturation oil layers.According to the dynamic characteristics of low-saturation reservoir exploitation,combined with geology,reservoir and other disciplines,to clarify the cause of low-saturation reservoirs;establish a reservoir moisture content calculation model based on relative permeability and crude oil viscosity by binding water saturation,permeability,regional crude oil properties and other data,and quantitatively calculate the reservoir based on reservoir static data.The water content in the early stage of dynamic mining forms a dynamic and static reservoir fluid identification method,accurately identifies the low saturation oil layer on the slope of Li County,and improves the compliance rate of regional interpretation.At the same time,a two-phase production capacity prediction model is established according to the reservoir yield,crude oil density and reservoir permeability,and the reservoir production capacity is established to estimate the reservoir production capacity and the region.The compliance rate of oil test and production results is high,which provides new technical support for the increase of regional reservoirs and production,and the effect is remarkable.
