成像测井技术在碳酸盐岩水平井中的应用

塔里木盆地北部地区碳酸盐岩油藏储层，非均质性较强，只依靠常规测井判断碳酸盐岩裂缝、溶孔、溶洞很困难．利用地层微电阻率扫描成像(FMI)，对碳酸盐岩水平井储层进行定性分析、定量解释，并能准确识别出碳酸盐岩目的层裂缝的性质、大小、开度、溶蚀孔洞原生孔隙、次生孔隙的发育情况等．同时并利用测试、酸压资料验证了使用成像测井判断裂缝的有效性．

THE APPLICATION OF FMI IN HORIZONTAL WELLS IN CARBONATE RESERVOIR

The carbonate reservoirs in northern Tarim Basin are heavily heterogeneous. Its hard to identify fissures and caves by using conventional logging. FMI techniques can be well used to qualitatively analysis and quantitatively evaluation carbonate reservoirs in Horizontal Wells. And it can accurately determine fissure features , the fissure angle, extension as well as the development of primary and secondary pores in carbonate reservoir . The application results of FMI are testified by well testing and acid fracturing data.
