海洋地质绿色勘查方法优化与实践

Optimization and practice of marine geological green exploration method

实施海洋地质绿色勘查是在新时期对海洋地质勘查工作提出的新任务、新要求。我单位积极践行绿色发展理念,以省内首批实施的海洋牧场项目“山东省威海市海洋牧场示范区海底沉积物地球化学调查”为试点,首先编制了院绿色勘查管理办法及相关实施细则,然后在施工过程中合理布置施工设备,改进船只定位技术、优化钻探施工工艺、改良地质取样过程,最大程度地减少用海面积、降低环境污染、避免阀架破坏。绿色勘查成果获自然资源部第二批绿色勘查项目,总结和积累的实践经验希望为其他地勘单位提供可复制、可推广的海洋地质绿色勘查工作方法。

The implementation of green exploration is a new task and new requirement for marine geological exploration in the new period We actively practice the concept of green development and take the marine ranch project“Marine Ranch Demonstration Area of Weihai City in Shandong Province”,which is the first marine ranch project implemented in the Shandong province,as the pilot project.We first formulated the green exploration management measures and relevant implementation rules,and then rationally arranged construction equipment in the construction process,including improving ship positioning technology,optimizing drilling construction technology,improving geological sampling process,minimizing the use of sea area,reducing environmental pollution and avoiding valve frame damage.The achievements of green exploration have been approved as the second batch of green exploration projects by the Ministry of Natural Resources.The practical experience is expected to provide a working model of marine geological green exploration that can be replicated and popularized for other geological exploration affiliations.
