该项目包括对索尔顿海科学钻探项目首席科学家的支持。在该项目的一期研究井,状态2-14,达到3219米深,遇到温度355℃和含23% TDS的富金属盐水。获得的岩心显示了从松散沉积到绿片岩相变质作用的转变。超过40个不同的研究小组参与,由跨部门协议(NSF, DOE, USGS)资助。二期项目将重点关注储层工程和地球化学采样。新井Wilson 1-12将在州2-14北部约1.5公里处钻探,目标深度为900 - 1800米,温度为210-305摄氏度。将获得岩屑、温度、压力和电缆测井数据,并对第一个可生产区域进行短期流动测试,以便从浅层油藏中取样低矿化度的流体。然后,Wilson 1-12将被用作处理井,对州2-14的深层油藏进行长期流量测试(长达30天)。从这两口井获得的新数据和样品将完成SSSDP的原始目标。本项目将进行的工作包括:(a)为规划和实施两口井的抽样和测试提供科学资料;(b)必要时与能源部、科学实验委员会和机构间委员会保持联络;(c)获取、描述和整理Wilson 1-12的钻屑;(d)必要时协调现场科学抽样和测量;(e)为不能在场的其他调查人员收集液体样本;(f)编辑SSSDP第一阶段科学成果会议论文集。
英文摘要
This project involves support for the Chief Scientist of the Salton Sea Scientific Drilling Project. In Phase I of the project the research borehole, State 2-14, reached 3,219 m deep, encountering temperatures 355oC and metal-rich brines containing 23 wt% TDS. The drill cores obtained demonstrate a transition from unconsolidated sediments to greenschist facies metamorphism. More than 40 different groups of investigators participated, funded by an interagency agreement (NSF, DOE, USGS). The Phase II program will focus on reservoir engineering and geochemical sampling. A new well (Wilson 1-12) will be drilled approximately 1.5 km north of the State 2-14 with a target depth of 900 to 1,800 m where temperatures of 210-305oC should be reached. Rock cuttings, temperature, pressure and wireline logs will be obtained and a short-term flow test of the first producible zones penetrated will permit sampling lower salinity fluids from the shallow reservoir. The Wilson 1-12 will then be used as a disposal well for long term flow tests (up to 30 days duration) of the deep reservoir in the State 2-14. The new data and samples obtained from these two wells will conclude the original objectives of the SSSDP. The work to be performed in this project includes: (a) scientific input to planning and implementing sampling and testing of the two wells; (b) liaison with the DOE, the Science Experiments Committee and the interagency committee, as necessary; (c) obtaining, describing and curating drill cuttings from the Wilson 1-12; (d) coordination of on-site scientific sampling and measurements, as necessary; (e) collection of fluid samples for other investigators who cannot be present; and (f) editing the conference proceedings on the scientific results of Phase I of the SSSDP.
