东濮凹陷桥口区块沙三段油气层测井识别方法

Well logging identification in Sha-3 section reservoir of Dongpu hollow Qiaokou block

为有效识别和评价东濮凹陷桥口区块油气层,需要在油气层地质特征及投产资料约束下建立一套适合本区块的测井识别评价方法。通过对xx井及邻井测井曲线响应特征的对比分析,总结了该区的储层测井响应特征,并利用交会图法、重叠法等多种测井解释技术进行了各组段储层的流体性质的识别。

The identification and assessment of well logging for reservoirs in Dongpu hollow Qiaokou block need to be set up on the basis of geological properties of reservoirs and operation information. The logging response features of reservoirs in this block are concluded by comparing logging curves of 59 well and its neighboring well. Other technologies such as cross-plot and overlapping are also applied to identify the fluid characteristics in different reservoirs.
