摘要: 重点讨论了新立油田扶杨油层水淹层在测井曲线上的变化特征,从物理机理上对其特征进行了分析。根据油田试油资料和产水率参数确定了油层的水淹级别,由实际的井资料建立了油田水淹层测井响应参数数据库,在此基础上,利用最大模糊隶属度判别法对一些井进行了水淹层的识别,划分水淹级别。通过实际应用表明,最大模糊隶属度法在新立油田水淹层评价中符合率,取得了较好的效果。

Abstract: The characteristics of well logging curve changing of watered out formation of Fuyang reseivoirs in Xinli oilfield is discussed, and the responses of well logging are analyzed. Based on the parameters such as water production rate and well test data, the grade of watered out formation are determined. database of well logging response of watered out formation is established, from which, a subordinate function and maximum fuzzy degree of membership to identify watered out formation, and classify different grades. The application shows the method is in accordence with the real situation well, a good agreement with the production data in watered out formation evaluation.

Key words: Xinli oilfield, watered out formation, well logging interpretation, watered out grade, fuzzy identification
