摘要

碳酸盐岩储层具有许多裂缝，且裂缝在采油中的作用非常重要。研究裂缝最有效的工具是从井中捕获高分辨率图像的图像测井。这些图像的一个例子是FMI工具，它提供了关于裂缝的方向、深度和类型的重要信息。目前，这些测井资料中的裂缝检测都是手工完成的，在缺乏足够经验的情况下，会遇到错误。本研究的目的是利用Canny边缘检测算法、Hough变换算法和图像处理算子对储层裂缝及裂缝的倾角进行识别，第一阶段在地质软件中进行裂缝识别，第二阶段利用MATLAB软件对裂缝及其倾角进行解释。

Identification of the fractures of carbonate reservoirs and determination of their dips from FMI image logs using Hough transform algorithm

Carbonate reservoirs are of great importance due to having many fractures and the effectiveness of these fractures in oil production. The most effective tools for studying fractures are image logs that capture high resolution images from the well. An example of these images is the FMI tool, which provide important information on the orientation, depth, and type of fracture. Today, the detection of fractures on these logs is done manually, which in the absence of sufficient experience, will encounter errors. The purpose of this study is to identify the reservoir fractures and the dips of the fractures using Canny edge detection algorithm and Hough transform algorithm and image processing operators, so that in the first stage, fractures are identified in Geolog Software and in the second stage, using MATLAB Software, fractures and their dip are interpreted.

期刊介绍： OGST - Revue d''IFP Energies nouvelles is a journal concerning all disciplines and fields relevant to exploration, production, refining, petrochemicals, and the use and economics of petroleum, natural gas, and other sources of energy, in particular alternative energies with in view of the energy transition. OGST - Revue d''IFP Energies nouvelles has an Editorial Committee made up of 15 leading European personalities from universities and from industry, and is indexed in the major international bibliographical databases. The journal publishes review articles, in English or in French, and topical issues, giving an overview of the contributions of complementary disciplines in tackling contemporary problems. Each article includes a detailed abstract in English. However, a French translation of the summaries can be provided to readers on request. Summaries of all papers published in the revue from 1974 can be consulted on this site. Over 1 000 papers that have been published since 1997 are freely available in full text form (as pdf files). Currently, over 10 000 downloads are recorded per month. Researchers in the above fields are invited to submit an article. Rigorous selection of the articles is ensured by a review process that involves IFPEN and external experts as well as the members of the editorial committee. It is preferable to submit the articles in English, either as independent papers or in association with one of the upcoming topical issues.
