摘要
本文针对油井液面深度测量方法进行研究，利用模糊集合论中的模糊聚类方法，提出了一种将液面回声仪记录的曲线根据油井接箍特点进行分档归类，然后求出液面深度。并在此基础上形成了一套完整的算法。该算法具有概念清晰、计算简单、实用性强的特点，可实现油井液面深度的自动监测，并提高测量准确度。
A method of depth measurement for an oil well's level is presented. Curves recording by level-echo instrument are classified according to an oil well's feature of joint, the depth of an oil well's level can be calculated. Using classified method of fuzzy sets theory, a simple and practical algorithm has been developed,which is also applicale to measure an oil well's level automatically and to improve the measurement precision.
