基于电成像测井的碳酸盐岩储层分类系统设计与实现

Design and implementation of carbonate reservoir classification system based on electric imaging logging

四川盆地普光地区碳酸盐岩储层发育裂缝和溶蚀孔洞,由于常规测井响应特征不明显,需要结合使用电成像测井资料来进行解释。针对碳酸盐岩在勘探开发中地层划分和类型识别的需要,采用Visual C++作为开发平台,并结合Oracle数据库和FTP文件系统,设计开发一套基于电成像测井的碳酸盐岩储层分类软件系统。该系统实现了对碳酸盐岩地层的自动分层和类型识别、成果显示及交互解释、Oracle数据库及FTP文件系统管理和多机使用等功能,并且具有良好的用户界面,操作方便,易于使用,对划分地层和确定地层类型处理效果良好,提高了资料处理解释效率。

The carbonate reservoirs in Puguang area of Sichuan basin develop dissolution pores and fractures.Because the conventional logging response characteristics are not obvious,it is necessary to interpret them with the combination of electrical imaging logging data.In order to meet the need of stratigraphic classification and type identification of carbonate rock in exploration and development,this paper designed and developed a software system of carbonate reservoir classification based on electrical imaging logging using Visual C＋＋ development platform and Oracle database and FTP file system.The system realized automatic stratification and type identification of carbonate stratum,result display and interactive interpretation,Oracle database and FTP file system management,multi-machine use and other functions,which had a good user interface,and easy to operate and use,to divide the stratum and determine the formation type of good treatment effect,and improved efficiency of data processing and interpretation.
