压裂选井选层的模糊物元评价模型及其应用

A Fuzzy Matter-element Evaluation Model to Selecting a Well and Selecting a Layer for Fracturing and Its Application

本文对影响压裂效果的因素分析,确定各因素最终权重,采用模糊物元评价模型,对需要进行压裂的井层经行排序。该方法克服了以往选井选层方法的盲目性,达到了科学决策的目的。并采用Visual Basic6.0语言对此方法经行软件编制,便于现场操作。

Fracturing to get a good yield, the choice of construction wells is very important. The traditional well and layer selection method based on experience, a certain subjectivity. In this paper, the impact of the factors fracturing analysis of the factors that ultimately determine the weights, fuzzy matter--element evaluation model Fracturing of the need for the trip by the well and the layer. The method overcomes the previous election Well layer of blindness. It provides a theoretic basis for fracturing construction. And using Visual Basic 6.0 to this method by lines of software compiled to facilitate on--site practice.
