针对尕斯油田下干柴沟组上段油藏的非常规储层、岩性复杂、多具过渡性和混合性,以灰岩为主,灰岩中主要有藻灰岩、泥晶灰岩等,非均质严重、有效储层划分和识别困难,横向上分布不稳定,成藏控制因素不清等情况。在收集了大量的岩心化验分析资料、录井、测井新技术资料(成像、ECS测井等)、试油和地质资料的基础上,对测井曲线进行了标准化处理;建立了一系列精细描述储层的地质参数;利用成像测井新技术、ECS元素测井新技术和常规测井资料对储层进行岩性识别;建立了适合该地区储层的岩性判断标准。为油田下一步的勘探开发提供了坚实的物质基础。
Aiming at the unconventional reservoirs in the Upper Member of Ganchaigou Formation in Gas Gas Field, the lithology is complex, multi-transitional and mixed, mainly composed of limestone. There are mainly algal limestone and limestone in limestone , Serious heterogeneity, difficulties in effective reservoir classification and identification, lateral distribution instability and unclear accumulation control factors. After collecting a large amount of core laboratory analysis data, logging and new logging data (imaging, ECS logging, etc.), oil testing and geological data, the logging curves were standardized and a series of fine Describe the geological parameters of the reservoir; use the new imaging logging technology, ECS element logging new technology and conventional logging data to identify the lithology of the reservoir; and establish the lithology judgment standard suitable for the reservoir in this area. It provides a solid material foundation for the next exploration and development of the oilfield.
