一种新的精细评价方法在安塞油田水平井中的应用

宋子齐等．一种新的精细评价方法在安塞油田水平井中的应用．测井技术，１９９４，１８（５）：３５７～３６５本文提出了用灰色理论精细评价储层的方法，并给出该方法在水平井测井解释中的应用实例。它用统计分析方法研究塞平１井的评价参数，确定每个评价参数的标准并进行精细的评价，同时开发出相应的绘图和显示软件。这些成果非常直观地显示了井筒所穿过的地层斜深、垂深、水平位移、斜厚、垂直厚度与储层的地质参数，揭示了油层空间位置及其横向岩性、物性、含油性沿井筒变化的情况，提供了直井无法得到的油层内的非均质变化规律及特征。

Application of A New Precise Evaluation Method to Horizontal Well in Ansai Oil Field.

An exact reservoir evaluation method with gray theory and its application to log interpretation of horizontal well are illustrated. The evaluating parameters for Well Saiping 1 are studied and the norm of each evaluation parameter is determined statistically. The corresponding plotting and display software is also developed. Displayed intuitively are the slope depth, vertical depth, horizontal displacement, slope thickness, vertical thickness of the formation drilled by the horizontal well and the geological parameters of the reservoir. The interpretation result shows the reservoir location in 3Ds and the changes of its lithology, physical properties, oil bearing properties along the borehole. And the reservoir characteristics and its heterogeneous variation law are provided, which can not be obtained from vertical well.
