Abstract

Abstract:

Blooey line is the one of indispensable ground equipment in gas drilling，which has potential safety hazard in high
pressure and high yield gas well drilling，but it is usually ignored in common. Because of solid particle erosion in high speed
air flow，failure destruction of blooey line occurs mainly in bending joint. Based on erosion destruction of bending joint，we
launch the study of erosion destruction mechanism and mathematical model，and carry on the theory discussion on erosion
angle of attack，erosion function，erosion coefficient of particle shape and the stress of the solid particle. At the same time，
this paper established the CFD finite element model and the angle of bending joint can change arbitrarily，which quantitatively
simulates erosion rate of multiphase flow containing solid particles to blooey line bending joint under different conditions and
do erosion mechanism research，and there is a series of CFD simulation study under the limitation flow rate（100×104 m3/d
and 50×104 m3/d）in different sand content. Finally，obtained quantitative relation curves between erosion rate and the angle
of joint，it provides the theoretical basis for the blooey line bending joint structure optimization in this paper.

Key words: blooey line, bending joint, erosion mechanism, CFD model, solid particle
