Problems solved by technology

However, in the existing scientific experiments in the petroleum field, the research work on the development and experimental simulation of portable deep formation rocks (artificial cores) and deep formation characteristics models (artificial formations) is relatively sufficient, but there is no shallow geological disaster yet. Advanced geological models and simulation devices have been put into experiments, and the safety of offshore oil and gas exploration and development is low

Abstract

The invention provides a portable seabed shallow geological hazard simulation device, which comprises an experimental assembly, a fluid conveying assembly and a pressure adjustment assembly, wherein the experimental assembly is used for simulating seabed shallow geological characteristics, the fluid conveying assembly is used for injecting an experimental fluid into the experimental assembly, thepressure adjustment assembly is used for adjusting the pressure inside the experimental assembly, the experimental assembly is internally preset with gravel used for simulating the unconsolidated formation, and two ends of the pressure adjustment assembly are respectively connected with the experimental assembly and the fluid conveying assembly. The portable seabed shallow geological hazard simulation device has the advantages of ensuring the safety of offshore oil and gas exploration and development and being convenient to carry.

Description

technical field [0001] The invention relates to an ocean drilling experiment instrument, in particular to a portable submarine shallow geological disaster simulation device. Background technique [0002] In offshore oil drilling, shallow geological hazards (shallow gas, shallow water flow and natural gas hydrate) widely exist, and disasters caused by offshore oil and gas exploration and development are not uncommon. Studying the geological characteristics of shallow geological hazards on the seabed and mastering the physical properties of shallow geological hazards can provide experimental and theoretical basis for pre-drilling prediction of shallow geological hazards. However, in the existing scientific experiments in the petroleum field, the research work on the development and experimental simulation of portable deep formation rocks (artificial cores) and deep formation characteristics models (artificial formations) is relatively sufficient, but there is no shallow geolog...
