油区整体效益状况评价方法

Assessment of Overall Benefit Status in Oil Region

在油区内已开发油气田区块和单井效益评价的基础上,有必要对油区层面油气生产整体效益状况进行评价。针对油区效益现状以及效益形势,可采用操作成本、高效区块产油量比例、高成本区块产油量比例、边际井和负效井比例以及盈亏平衡油价与决策油价比值等5项评价指标来进行评价。应用上述5项指标,对某油区的效益现状进行了描述,对效益形势进行了分析,对效益前景进行了预测。上述评价方法能够比较全面系统地反映油区的效益状况,应用效果较好。

On the basis of benefit evaluation of developed oilfield block and single well in an oil region, it is necessary to make the assessment of the whole oil-gas producing benefits in an oil region. The indicators for assessment of the existing benefit status include the operation cost, oil production ratio of high-yielding block, oil production ration of high-cost block, marginal well or negative efficient well ratio, break-even oil price-decision oil price ratio. Description and analysis of benefit status as well as prediction of benefit prospect in an oil region are made by using these 5 indicators. Results show that these methods can be well applied to comprehensively systematically reflect the benefit status of an oil region.
