Long-Term Monitoring of Off-Axis Hydrogeology on the Costa Rica Rift Using an Instrumented Wireline Multi-Packer System

OCE 9819780 Spiess--推荐的项目将开发和部署两种可通过钢丝绳部署的新一代仪表化井眼密封（循环阻塞物改造套件或CORKs），它们将整体包含仪表化多封隔器。 这些集成系统将由海洋物理实验室、斯克里普斯海洋学研究所电缆控制车完全部署和回收，使这些下一代软木塞的安装和回收可以由方便的船只而不是ODP钻井船JOIDES Resolution来完成。 这两个系统将安装在504 B孔和附近的896 A孔内，以测量哥斯达黎加裂谷南翼上洋壳内的现场水文地质流体流动和过程。 该电缆系统的开发实现了1997年12月由JOI/USSP主办的“高级CORSs”研讨会提出的未来CORSs开发的两个原则建议-1）独立密封和监测多个地层区域; 2）最大限度地利用电缆进入密封井眼。

OCE9819780Spiess--The recommended project will develop and deploy two wireline-deployable, new-generation instrumented borehole seals (Circulation Obviation Retrofit Kits or CORKs) that will integrally contain instrumented multi-packers. These integrated systems will be fully deployable and recoverable by the Marine Physical Lab, Scripps Institution of Oceanography wireline Control Vehicle, making installation and recovery of these next-generation CORKs possible by ships of convenience rather than the ODP drillship JOIDES Resolution. These two systems will be installed within Hole 504B and the nearby Hole 896A to measure in-situ hydrogeological fluid flow and processes within the upper oceanic crust on the south flank of the Costa Rica Rift. Development of this wireline system fulfills the two principle recommendations for future CORK development proposed by the December, 1997 JOI/USSP-sponsored workshop on "Advanced CORKs"- that of 1) independent sealing and monitoring of multiple formations zones; and 2) maximizing wireline access to sealed boreholes.***
