Deep Earth Sampling System

取心深研究威尔斯12至15公里的可行性。 (40 000至50，000英尺）使用连续油管钻机和小井眼 正在研究取心工具。 第一阶段技术审查和 分析了连续油管的关键部件， 取芯系统，以确定是否可以适应现有的 连续油管钻机到深取芯应用。 审查表明 一个15公里（50，000）的采样系统可以在五年内开发出来， 年和一个较浅的系统取芯，至6公里（20，000英尺），可以 通过改造现有的连续油管钻机来开发。 在第二阶段，高强度油管柱的建造将 追究 深井和深井所需的井下部件 和一个较浅的连续油管采样系统将在测试中， 实验室和浅场现场下至0.6公里（2000英尺）。 较浅的系统在采矿中有直接的应用， 石油勘探、浅层科学取样和水平 钻井

The feasibility of coring deep research wells 12 to 15km. (40,000 to 50,000 ft.) using coiled-tubing drill rigs and slim hole coring tool is being investigated. A Phase I technical review and analysis was performed of critical components of a coiled-tubing coring system to determine if it is feasible to adapt existing coiled-tubing rigs to deep coring applications. The review showed that a 15km (50,000) sampling system could by developed within five years and a shallower system for coring, to 6km (20,000 ft.), could be developed today by retrofitting existing coiled tubing rigs. In Phase II, the construction of a high-strength tubing string will be investigated. Downhole components required for both the deep and a shallower coiled-tubing sampling system will be tested in the laboratory and in shallow field sites down to 0.6 km (2000 ft). The shallower system has immediate application in mining and petroleum exploration, shallow scientific sampling, and horizontal drilling.
