Fluid production test at the KTB-VB

德意志联邦共和国（KTB）的大陆发展计划取得了巨大成功。它揭示了丰富的地球科学数据和质量和广度无与伦比的新成果。然而，几个主要目标只进行了粗略的调查，两个KTB钻孔，4.0公里深的先导孔（KTB- vb）和9.1公里深的主孔（KTB- hb）的科学潜力也没有得到充分利用。本项目及相关项目的总体目标是研究KTB钻井现场大陆断层系统中的能量和流体输送过程。为此目的，建议在KTB-VB进行为期12个月的产液试验。在测试期间，将实时监测各种地球物理、水力和地球化学参数。将定期采集未受污染的深部地壳流体和气体样本，进行进一步详细的地球化学、地质生物学和同位素调查。数据和样本将提供给来自不同机构的几个研究小组进行进一步的详细评估。在这个项目中，将协调科学小组的业务工作和任务，还将详细调查地壳气体的地球化学和同位素组成。

The Kontinentale Tiefbohrprogramm der Bundesrepublik Deutschland (KTB) was enormously successful. It has revealed a wealth of geoscientific data and new results of unrivalled quality and broadness. However, several of the main objectives have only been marginally investigated, and the scientific potential of the two KTB boreholes, the 4.0 km deep pilot hole (KTB-VB) and the 9.1 km deep main hole (KTB-HB) has by no means fully exploited. The general aim of this and accompanying projects is to study energy and fluid transport processes in continental fault systems at the KTB drill site. For that purpose it is proposed to carry out a fluid production test during a period of 12 months in the KTB-VB. During the test various geophysical, hydraulic and geochemical parameters will be monitored in real-time. Samples of uncontaminated deep seated crustal fluids and gases will be taken regularly for further detailed geochemical, geobiological and isotopic investigations. Data and samples will be provided to several research groups from different institutions for further detailed evaluation. Within this project, the operational work, and tasks of the science team will be co-ordinated, also geochemistry and isotopic composition of crustal gases will be investigated in detail.
