横向测井资料识别碳酸盐岩裂缝方法研究

世界上许多大油气田和高产油气井的油气都是来自碳酸盐岩储集层,碳酸盐岩储集层的裂缝是油气重要的储集空间和渗流通道,裂缝的预测和正确认识对油气的勘探、开发具有重要意义,测井资料是其最基础和最重要的资料之一。然而在老油(气)田中,我们拥有的大量测井资料都属于老测井系列,如何利用这些资料进行裂缝的有效识别就变得很重要了。本文针对齐家务大中旺地区大多数井的资料为横向测井,采用岩心刻度测井方法来提取碳酸盐岩裂缝的测井响应特征,形成一个识别裂缝的标准。该标准应用于大中旺地区,效果良好。

A Study on the Identification of Fractures in Carbonate Rocks by Using Lateral Logging Data

Lots of oil and gas in big oil & gas fields and high productive oil & gas wells of the world come from carbonate reservoir. Fractures in carbonate reservoir are important to oil & gas storage space and seepage channel. Predicting and correctly understanding fractures has the vital significance for the oil & gas exploration. The logging data is one of the most basic and important information. However, in old oil (gas) field, we have a lot of logging information that is old. Therefore, how to use such information to identify fractures becomes very important. This article uses log curves with core data to pick up the log characteristics in the fracture carbonate rocks and then makes a standard identifying fractures.
