Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the experiment dress that a kind of simulated formation water yield of the utility model influences on gas horizontal well drilling annular space
Put, mainly by high-speed camera 1, computer monitoring system 2, pressure sensor 3, pipe joint 4, gas-particle two-phase import 5, landwaste
Funnel 6, cutting grain 7, ball valve A8, gas flowmeter 9, air compressor machine 10, landwaste collecting box 11, wire netting 12, mixture outlet
13rd, iron plate 14, inner tube 15, outer tube 16, fluidized bed dryer 17, landwaste collecting vessel 18, suspension ring 19, drill bit 20, water inlet are tilted
21st, ball valve B22, fluid flowmeter 23, water pump 24 and hopper 25 form.Air compressor machine 10 successively with gas flowmeter 9, ball valve
A8, landwaste funnel 6 are connected with gas-particle two-phase import 5, and hopper 25 is successively with water pump 24, fluid flowmeter 23, ball valve B22 and entering
The mouth of a river 21 is connected, and the right part of landwaste collecting box 11 is provided with the wire netting 12 of rectangle, and bottom is provided with two pieces of inclination iron plates 14.
As shown in figure 1, physical simulation process is：Be first turned on air compressor machine 10, make gas from air compressor machine 10 come out after successively
After gas flowmeter 9, ball valve A8, together with the cutting grain 7 of the outflow of landwaste funnel 6 out of gas-particle two-phase import 5 entrance
Inside pipe 15, gas and cutting grain 7 flow from top to bottom in inner tube 15, are finally flowed out from drill bit 20；Work as computer monitoring
In system 2 after the pressure level-off of display, water pump 24 is opened, the water in hopper 25 is pressurizeed successively by water pump 24, liquid
After flowmeter body 23 and ball valve B22, enter outer tube 16 from water inlet 21.When experiment just starts, regulation ball valve B22 apertures, make
