ECONOMIC EVALUATION OF MEASURES FOR INCREASING PRODUCTION IN OIL WELL

摘要: 油井增产措施有多种类型, 不同措施会带来不同的增产效果, 但又都有不同的成本组合.提出了一种对油井增产措施的经济评价的改进方法.该方法第一步是措施后累积增产量的预测, 第二步是投资估算和成本估算, 最后是对方案进行净收益分析、经济极限分析和敏感性分析, 给出了某油井的实际评价结果, 证明了该方法的有效性.

Abstract: Measures for the increase in oil production in oil wells are of various types. Different measures may bring about different effects of the increase in oil production. However, they also have different cost combinations. In this paper, a method is proposed for the improvement in the economic evaluation of different measures for the increase in oil production. The first step of this method is to forecast the accumulated increase in oil production after the measure is adopted. The second step is to estimate the investments and costs. The final step is to make net benefit, economic limit, and sensitivity analyses of the measure adopted. Consequently, the actual evaluation result of a certain oil well is obtained to prove the effectiveness of this method.
