机械采油方式的适应性评价

Evaluation on adaptability of artificial lift methods

选择正确的机械采油方式是油气井获得长期最佳效益的关键，而机械采油方式的确定必须以其适应性评价为基础。过去主要是基于经验总结的定性描述来选择机械采油方式，具有一定的主观性和随意性。为此，提出将机械采油方式的适应性评价视为多层次的模糊决策问题，结合层次分析方法、模糊分析和Saaty相对比较法对其进行适应性评价。给出了有关公式，并进行了实例计算，为机械采油方式决策的定量化、科学化和最优化提供了一种新方法。

Rational selection of artificial lift methods is the key to getting the greatest benefit from a well in the long term. The selection of artificial lift methods used to be based on empirical qualitative analysis, therefore it is subjective and random.In this article, it is recommended selecting the artificial lift method on the basis of its adaptability evaluation. And the e valuation is considered as a problem of multiple-hierachy fuzzy decision, and the solution is obtained by combining AHP (Analytical Hierarchy Process) with fuzzy deciding analysis and Saaty's relative comparison method. Relevant equations are given, and an example of calculation is presented. Thereby a new method is provided for the quantitative, scientific and optimal decision of artificial lift methods.
