油价桶油操作成本比对SEC储量影响分析及应用

Analysis and Application of the Impact of Ratio of Oil Price and Single Barrel Operation Cost on SEC Reserves

摘要: 成本变化是影响SEC储量变化的重要因素，降低成本最大程度增加SEC储量意义重大。以非经济可采储量为研究对象，定义了油价桶油操作成本比参数，推导建立了以油价桶油操作成本比表征的非经济可采储量表达式，明确了非经济可采储量在不同油价桶油操作成本比区间敏感性，确定了影响SEC储量变化速率的主要因素是技术可采储量规模和油价桶油操作成本的比值。油价桶油成本比越低、技术可采储量规模越大，控本增储效果越明显。实例表明通过技术可采储量规模和油价桶油成本比的范围区间优化筛选具体油田，可以指导成本优化的方向，最大限度增加SEC储量。

Abstract: Cost change is an important factor affecting the change of SEC reserves. It is of great significance to reduce costs and maximize SEC reserves. Taking the non economic recoverable reserves as the research object, this paper defines the ratio of oil price and single barrel operating cost, establishes the expression of non economic recoverable reserves represented by ratio of oil price and single barrel operating cost, defines the sensitivity of non economic recoverable reserves in different ratio range of oil price and single barrel operating cost, and determines that the main factor affecting the change rate of SEC reserves is technical recoverable reserves and ratio of oil price and single barrel operating cost. The lower the oil price to barrel cost ratio and the larger the scale of technically recoverable reserves, the more obvious the effect of cost control and storage increase. The example shows that selecting specific oil fields by optimizing the range of technical recoverable reserves and the cost ratio of oil price to barrel oil can guide the direction of cost optimization and maximize SEC reserves.
