Analysis and application of the key technology in geologic drilling in shallow sea

Abstract:

Exploration and development of marine solid mineral resources is an important part of marine development and utilization. Some technical measures were summarized and discussed on drilling projects in shallow waters from drilling equipment, technology, safety, etc. First, it is necessary to choose a safe and reliable drilling platform based on the characteristics of the marine environment，in addition to selecting conventional drilling equipment based on geological requirements. Second, the drilling structure design, drilling method and washing fluid should be carried out according to the characteristics and requirements of the sea area. Third, we must adhere to the principle of safety first and compile safety emergency plans. Through the application example of the gold exploration in the northern sea area of San Shandao, the adaptability of marine geological drilling engineering technology has been proven，it provided some experience references for related shallow sea geological drilling projects.
