Abstract
A kind of drilling well side well hydrocone type mud exhaust device, the lower end of high-pressure delivery pipe is connected to the entrance of siphon generator bottom, the upper end of high-pressure delivery pipe is connected to the outlet side of slush pump, the outlet side of siphon generator is connected with the lower end of discharge pipe, the upper end of discharge pipe is above vibrosieve, siphon generator is placed on, the bottom of Fang Jing, mix slurry and enter pipe insertion Fang Jingli, stock pump sprays at a high speed after high-pressure slurry is pumped into siphon generator, make the pressure drop outside siphon generator, mixing in Fang Jing slurry can flow to and in siphon generator, be pressurized discharge, through vibrosieve and rock cut separate after mud enter the circulating system and continue on for drilling well, do not need to beat and carry the mud that rock is cut with centrifugal pump, therefore, the utility model can overcome the problem of above-mentioned existence, can continuously discharge and contain the mud that bulky grain rock is cut, the drilling well circulating system is normally worked, use manpower and material resources sparingly, improve drilling efficiency, there is significant economic benefit.
Description
Technical field
The utility model is that oil drilling purifies the equipment that mud is used, and is a kind of drilling well side well hydrocone type mud exhaust device.
Background technology
In oil drilling, in pit shaft, carry rock for the mud creeping into and cut while returning to ground, first flow in Fang Jing and store, be then drawn to vibrosieve from Fang Jingli and separate, after mud that drilling well uses and rock being cut separate, enter the circulating system and continue on for drilling well.At present, the equipment of extracting mixing slurry from Fang Jingli out is centrifugal pump (scene is called stock pump), there is rock to cut owing to mixing in slurry, particle is large, easily block centrifugal pump or wearing and tearing centrifugal pump, make its operational system undesired, need often to discharge fault ability normal construction, drop into a large amount of manpower and materials, drilling efficiency is low.
Summary of the invention
The purpose of this utility model is a kind of drilling well side of design well hydrocone type mud exhaust device, overcomes the problem of above-mentioned existence, makes its mixing slurry of continuously discharging Fang Jingli, reduces the workload of fixing a breakdown, and improves drilling efficiency.
The purpose of this utility model is achieved in that involving vibrations sieve, siphon generator, discharge pipe, Fang Jing, mixing slurry enter pipe, high-pressure delivery pipe, slush pump, the lower end of high-pressure delivery pipe is connected to the entrance of siphon generator bottom, the upper end of high-pressure delivery pipe is connected to the outlet side of slush pump, the outlet side of siphon generator is connected with the lower end of discharge pipe, the upper end of discharge pipe is above vibrosieve, siphon generator is placed on, the bottom of Fang Jing, mixes slurry and enters pipe insertion Fang Jingli.
The beneficial effects of the utility model are: slush pump sprays at a high speed after high-pressure slurry is pumped into siphon generator, make the pressure drop outside siphon generator, mixing in Fang Jing slurry can flow to and in siphon generator, be pressurized discharge, through vibrosieve and rock cut separate after mud enter the circulating system and continue on for drilling well, do not need to beat and carry the mud that rock is cut with centrifugal pump, therefore, the utility model can overcome the problem of above-mentioned existence, can continuously discharge and contain the mud that bulky grain rock is cut, the drilling well circulating system is normally worked, use manpower and material resources sparingly, improve drilling efficiency, there is significant economic benefit.
Brief description of the drawings
The schematic diagram of Fig. 1 the utility model embodiment.
Detailed description of the invention
Describe below in conjunction with Fig. 1 embodiment of the present utility model.
As seen from the figure, embodiment involving vibrations sieve 1 of the present utility model, siphon generator 2, discharge pipe 3, square well 4, mixing slurry enter pipe 5, high-pressure delivery pipe 6, slush pump 7, the lower end of high-pressure delivery pipe 6 is connected to the entrance of siphon generator 2 bottoms, the upper end of high-pressure delivery pipe 6 is connected to the outlet side of slush pump 7, the outlet side of siphon generator 2 is connected with the lower end of discharge pipe 3, the upper end of discharge pipe 3 is above vibrosieve 1, siphon generator 2 is placed on, the bottom of side's well 4, mixes slurry and enters 4 li, pipe 5 insertion side's well.
Entering stratum and carry rock and cut in drilling rod, ground mud enters 4 li, pipe 5 inflow side's well through mixing slurry, because the head of liquid that the slurry of the mixing in square well 4 produces at siphon generator 2 places is lower than atmospheric pressure, so the mixing that siphon generator 2 is worked in time side's well 4 is starched the low-pressure area that can enter in siphon generator 2 and is discharged.
