低孔低渗储层产能预测方法研究

Productivity prediction method of low porosity and low permeability reservoir

油井产能反映一口井产油动态特征的综合指标,是编制和预测油田勘探、开发方案的重要组成部分,X区块是吉林油田典型的低孔低渗储层,并且非均质性强,从而造成了产能定量评价难以确定,本文从常规测井曲线入手,结合试油资料,对X区块建立米产液模型、及米产油模型,预测结果与试油结果较为符合,取得了良好的效果。

The comprehensive index of oil well productivity reflecting the dynamic characteristics of oil production of a well is an important part of the formulation and prediction of oilfield exploration and development program.Block x is a typical low porosity and low permeability reservoir in Jilin Oilfield,and it has strong heterogeneity,which makes it difficult to determine the quantitative evaluation of production capacity.This paper starts with the conventional logging curve and combines the oil test data to establish meter production fluid for block X The prediction results of the model and rice oil production model are in good agreement with the oil test results,and good results have been achieved.
