多元线性回归分析在安塞油田产量预测中的应用

Application of Multiple Linear Regression Analysis in Forecasting Ansai Oilfield Output

基于石油地质理论,利用统计学的方法对测定的各种数据进行统计学分析,发现变量之间的内在联系,指导我们的石油勘探开发。根据安塞油田某区块53口生产井的物性资料和产量数据,利用多元线性回归统计学方法得出产量的经验公式,利用此公式可以对新钻井进行产量预测,并根据油价来进行经济评价,有效控制投资风险。本方法可以和其他评价方法并联使用,在减小勘探开发风险方面有一定的作用。

Based on the existing petroleum geological theory,statistic method can be used to find out the internal relationships among variables in order to guide the exploration and development of petroleum.Accordingto the materality information and output data of 53 oil wells in Ansai Oilfield,an output formula was worked out by way of multiple linear regression statistics.This formula can be used to forecast oil wells'output and to make an economical evaluation of the wells.Thus the risks in exploration may be effectively decreased when applied with other evaluation approaches.
