使用不断发展的循环观测改造套件 (CORK) 水文观测技术对海洋钻探计划 (ODP) 和综合海洋钻探计划 (IODP) 钻孔进行长期地层压力监测，由于记录间隔持续时间的延长和测量保真度的提高，带来了意想不到的应用。目前的功能可在从静态到 1 Hz 的广泛时间尺度内提供具有地质意义的观测结果，从而可以研究许多耦合的水文、地球动力学和地震现象。在这篇综述中，我们提出了对记录保真度当前限制进行限制的观察结果，以及泄漏如何影响压力观察结果的示例。
Long-term formation pressure monitoring in Ocean Drilling Program (ODP) and Integrated Ocean Drilling Program (IODP) boreholes using evolving Circulation Obviation Retrofit Kit (CORK) hydrologic observatory technology has led to unanticipated applications as a result of the growing duration of recording intervals and the improvement of measurement fidelity. Current capabilities provide geologically meaningful observations over a broad range of time scales from static state to 1 Hz, allowing investigations of many coupled hydrologic, geodynamic, and seismologic phenomena. In this review, we present observations that provide constraints on current limits to recording fidelity, and examples of how leakage can affect pressure observations.
