The resolution of evaluation results is sometimes low when using the present gray association analysis to evaluate the geological models of lithology,physical properties,oil potential and oil-bearing area.
针对目前灰色关联分析方法在评价岩性、物性、含油性、含油面积等地质模型中有时存在评价结果分辨率不高的问题,基于信息论中Jaynes最大信息熵原理和灰色关联度的定义,构造目标函数,运用拉格朗日乘数法,建立了一种新的灰色精细评价模型。
In the process of reserve calculation using volumetric method, to confirm oil-bearing area is in fact to calculate polygon area.
在用容积法计算地质储量的过程中,含油面积的确定实际上是计算多边形的面积。
Reservoir engineering method is adopted to calculate recovery indexes such as the horizontal well's limited recovery factors, well drainage area, reservoir limited recoverable reserves and water cut an.
应用油藏工程方法计算了水平井极限采收率、泄油面积和油藏极限可采储量、含水率等开发指标,其结果与数值模拟结果基本吻合。
