基于复合分组的油田操作成本指数分析方法及应用研究

Research on Oilfield Operating Cost Index Analysis Based on Composite Grouping

在对研究对象按2个以上标志进行复合分组的基础上,根据统计指数分析原理和方法,从不同角度和层次对研究对象进行分析,以便弄清楚研究对象的变动及其原因。以油田操作成本为研究对象,采用复合分组的方法,对油田操作成本按区块、采油方式和含水率进行复合分组,借助于总指数分析方法的总平均指标变动分析方法,通过计算油田操作成本指数、原油产量指数、单位产量操作成本指数,进而从区块、采油方式和含水率角度分别对影响油田单位产量操作的变动作进一步分析,找到影响油田操作成本变动的因素,以及变动因素对油田操作成本变动影响的相对数和绝对数,为油田操作成本控制提供依据。

Based on the composite grouping of two or more references on the research object, the research object is analyzed from different angles and levels according to the principles and methods of statistical index analysis, in order to clarify the change of the research object and reasons for the change. This paper takes the oilfield operating cost as the research object, adopts the method of composite grouping to group the oilfield operating costs by blocks, oil production methods, and water-cut rate, and uses the total average index change analysis method to calculate oilfield operating cost index, oil production index and unit production operating cost index, thereby, from the perspective of blocks, oil production methods and water-cut rate, further analyzing the changes affecting the unit production operating cost of the oilfield. Through analysis, it identifies variable elements in operating costs of the oilfield, as well as each variable element＇s relative and absolute impact values affecting the changes of the operating costs, providing basis for oilfield operating cost control.
