Mechanism Study of Gas Drilling Dust Removal of Water-Affusion
Fan Qiang, Gui Guojing, Jiu Songtao
Abstract: The prevention and control of debris particles is always a big problem in gas drilling for safety production. On the basis of the force analysis of the debris particles in sand pipeline is built up. Under some certain assumptions, the subsidence rules of the debris particles with different dimensions are analyzed and calculated. The result shows that the debris whichs across are bigger than 25 micron can subsidence by themselves and whichs across are smaller than 20 micron cant subsidence by themselves. These small particles will be a threaten to peoples health and the environment. So it is needed to water injection and dust. In combination with the interaction mechanism between water and debris particles, some measures to improve the effect of water injection and dust in gas drilling are put forward, the methods that against the current direction, water at the eccentric position and add dustfall agent will be used to improve the effect.
Keywords: debris, gas drilling, stress analysis, subsidence rules, water injection and dust
