Hydrogeology Experiments in the Ocean Drilling Program, 1988-1990

井下测量和测井已被证明是 海洋科学活动的重要组成部分 钻井程序。最重要的科学之一 ODP头两年的成功是广泛的 井下地球物理测量项目， 腿102、109和111位于深深穿透到 大洋地壳从这些孔的数据已被用来解决 海洋的物理、化学和水文地质状态 并允许从洞里的样本数据进行外推 到区域规模。 目前的奖项将支持贝克博士在大学 迈阿密进行了一系列水文地质实验， 未来两年的钻探。实验包括一个 钻柱封隔器，其允许孔的部分被 隔离并检查流体流动;大规模电阻率 测试地壳岩石电特性的实验;以及， 流量计实验，以监测流体流入地壳孔。 这些实验将提供基本的数据， 地壳的性质（渗透性、孔隙度和孔隙度 压力），控制地壳流体的运动 大洋地壳

Downhole measurements and logging have proven to be an essential component of the scientific operations of the Ocean Drilling Program. One of the most significant scientific successes of the first two years of ODP has been the extensive programs of downhole geophysical measurements conducted during Legs 102, 109, and 111 in holes that penetrate deep into the oceanic crust. Data from these holes has been used to resolve the physical, chemical, and hydrogeological state of the oceanic crust and allow data on samples from the hole to be extrapolated to the regional scale. The present award will support Dr. Becker at the University of Miami to undertake a series of hydrogeology experiments during the next two years of drilling. The experiments include a drillstring packer which allows sections of the hole to be isolated and examined for fluid flow; a large-scale resistivity experiment to examine electrical properties of crustal rock; and, flowmeter experiments to monitor fluid flow into crustal holes. These experiments will provide essential data on the basic properties of the crust (permeability, porosity, and pore pressure) which control the movement of crustal fluids in the oceanic crust.
