油井试挤技术是在实践中总结摸索出来的一种简单实用的地层解堵技术.针对传统评价方法只注重累增油指标的片面性和不确定性,应用模糊数学理论评价油井试挤效果,首先选取日增油量、试挤有效期和试挤次数三个评价指标,然后利用层次分析方法确定各指标的合理权重,最后根据模糊综合评价得出评价结果.结果表明,方法可以精确评价油井的试挤效果,具有一定的推广价值.
Well test-and-extrusion technology is a simple and practical method to solve strata that has been explored in practice.Aiming at the traditional evaluation method which focuses on the one-sidedness and uncertainty of oil accumulation indexes, Then, we select three evaluation indexes, such as the daily oil increment, the expiry date of the trial and the number of trial crowds, and then use the analytic hierarchy process to determine the reasonable weight of each index. Finally, the evaluation results are obtained based on the fuzzy comprehensive evaluation.The results show that the method can accurately evaluate the oil well Test squeeze effect, with some promotional value.
