丰县官庄组含盐亚段盐群地层测井曲线特征分析与对比

Analysis and Comparison of Logging Characteristics of Salt Formation in Salt Submember of Fengxian Guanzhuang Formation

测井曲线对比具有表现直观、应用方便、成果资料及时等特点,通过对测井曲线的综合对比,结合地质资料进行综合判断比较分析和研究,可以进一步提高盐层对比的可靠性。采用盐岩层组合特征及盐群地球物理特性,通过对淮安张兴块段盐岩井第Ⅲ盐群测井的各物性参数曲线特征分析和曲线特征的对比,可看出,第Ⅲ盐群沉积环境比较稳定,物性差异明显,测井曲线组合规律性强,形态特征突出,标志层特征明显。

The comparison of logging curves has the characteristics of intuitive performance, convenient application and timely results. Through the comprehensive comparison of logging curves and combined with geological data, the reliability of salt layer comparison can be further improved. Using gypsum layers combination characteristics and physical properties of salt of the earth through the first Ⅲ period of gypsum block of Huai’an Zhangxing well salt group of various physical parameters logging curve characteristics analysis and comparison of characteristics of curve, we can see, the first Ⅲ salt group of stable sedimentary environment, physical difference to be markedly, logging curve combination strong regularity, morphological characteristics, characteristic of strata is obvious.
