塔中卡1区块的主要勘探目的层为奥陶系碳酸盐岩储层,其储渗空间为孔隙、裂缝、溶孔(洞)及它们之间的相互组合。本文主要介绍FMI测井资料在中1、中11、中12、中13等井碳酸盐岩地层中的应用效果,主要包括井旁构造分析、地层特征的描述、裂缝、溶蚀孔洞的识别、地应力分析、多井地层界面对比等。资料应用效果表明:成像测井资料可以准确地判断裂缝、溶蚀孔(洞)发育的层段和发育程度,是碳酸盐岩储层评价的有力工具。
The main exploration target layer of Tazhongka block 1 is Ordovician carbonate reservoirs, and the storage and storage spaces are pores, cracks, dissolved pores (holes) and their mutual combination. This paper mainly introduces the application of FMI logging data in the carbonate rock formations such as Zhong 1, Zhong 11, Zhong 12, Zhong 13, etc. The main results include well-side structure analysis, stratum characterization, fractures, dissolution hole identification, Ground stress analysis, multi-well formation interface comparison. The data application results show that the imaging logging data can accurately judge the intervals and development of fractures and dissolution pores (holes), which are powerful tools for carbonate reservoir evaluation.
