Abstract

A deep-water drilling gas kick pilot-scale apparatus, including: a simulation wellbore having an upper wellbore transitioned to a lower wellbore through a variable cross section; a drilling tool with an annular space formed between the drilling tool and the simulation wellbore; a gas-injection system, comprising an air compressor and a gas-injection pipeline; a mud circulation system, comprising a mud supply source, a first pump, a second pump, and a mud-return pipeline; a Coriolis mass flowmeter provided on the mud-return pipeline; a Doppler sensor installed on the upper wellbore; and a built-in pressure gauge carrier connected between a drill pipe and a drill bit.
