摘要
从渗流力学的基本原理出发,分析了影响比采油指数的关键因素。根据测井学基本理论,建立了比采油指数与测井主要参数(孔隙度、泥质体积分数、电阻率及原油黏度)的相关式。以渤海油田某区域探井测试数据为基础,通过引入校正系数,采用多元线性回归的方式,对该区域比采油指数进行了求解,建立了该区域比采油指数预测方法,并以渤海X油田为例,对该方法进行了验证。研究结果表明,通过对泥质体积分数引入校正系数,能够利用测井资料和原油物性参数预测单井的比采油指数。该方法预测精度高,对海上油田产能评价具有指导意义。
Based on the principle of seepage mechanics,the key effect factors of specific productivity index are analyzed.Using the theory of well logging,the correlation of specific productivity index with logging parameters resistivity,porosity,clay content,and crude oil viscosity is formulated.Taking test data in the Bohai Sea Oilfield as the foundation,the specific productivity index of the region is solved through the introduction of a calibration factor and the use of multivariate linear regression,and the prediction method of regional production index is established.Finally this method is verified by Bohai X Oilfield production data.The results show that through the introducing correction factor of shale content,specific productivity index can be forecasted by the log information and the crude oil viscosity,and with its high forecast precision,this method has important guiding significance for the offshore oilfield productivity evaluation.
