摘　　要：裂缝型油气藏是石油增储上的重要领域之一。裂缝的存在既为油气的储存提供了有效的空间和运移通道，又对储层的产储性能有着重要的影响。而我国又有着较大的裂缝性储集层的地质储量，进行裂缝性油气藏的研究和预测，对中国深层油气藏的勘探突破具有深远意义。然而，在老的油气田中，大量测井资料都属于常规测井系列，如何利用这些资料进行裂缝的有效识别就变得十分重要了。本文利用西北缘地区石炭系的常规测井资料，结合弹性力学参数，形成一个识别裂缝的标准。该标准应用于西北缘地区石炭系，效果良好。Fracture hydrocarbon reservoir is one of the important areas to increase oil reserves and production.Fractures can not only provide effective space and migration pathway for oil and gas,but also have important effect on the performance of production and storage.There is a big ge- ological reserves of fracture reservoirs in our country.Research and prediction to fractured reservoirs are of far-reaching significance to the exploration breakthrough of deep hydrocarhon reservoirs.However,there are a lot of logging data which belong to conventional logging data in old oilfield.How to identify fractures effectively with these data becomes very important.In the paper,a standard for fracture identification is established with combination of conventional logging data in this area and elasticty parameters.The application result is good.
