基于海底钻机的多功能原位测试系统开发与应用
|
摘要
基于海底钻机的原位测试是一种新型的海底地层测试方式.结合"海牛号"60 m海底钻机的实际工况需求,研制一套以静力触探为技术基础的多功能原位测试仪,可以在水下2 000 m的海底实现对锥尖阻力、侧壁摩擦力、孔隙水压力、温度、电阻率和视频的原位信息采集.本文从测试方法、系统结构、探头传感器、数据采集等方面进行了详细介绍,现场试验显示多功能原位测试仪能够按照预定设计完成原位测试的全部功能,采集的数据与海床式静力触探系统对比具有极强的一致性.
The in-situ testing based on the seabed drill rig is a new way to place sensors into the earth.Combined with the actual working condition of seabed drill rig,a set of multi-function in-situ tester based on cone penetration testing( CPT) was developed,which was able to capture tip-resistance,sleeve-friction,porepressure,temperature, electrical-resistivity and video under 2 000 m water. The test method, system architecture,cone and test sensors,and data acquisition were described in detail. The field test confirmed that the in-situ tester work properly in accordance with a predetermined design,and the test data is consistent with the data of seabed CPT system.
