Upper andlower hoop arms are respectively arranged at the two ends of upper and lower hoops. The pipeline comprises a pipe body and a joint, and the reverse side of the joint adopts the structure of an inclined plane. The upper and lower hoops are connected by a bolt. The silt removing pipeline solves the problem in the prior art that the installation and preparation of the equipment consume more time. Being quickly connected by the hoops and fixed by the bolt, the silt removing pipeline has the characteristics of simple structure, low cost and convenient processing as well as manufacturing.
Description
Technical field:
A kind of row's sand tube line that is applicable to gas drilling is used for adopting gas to implement the discharge of the downhole debris of under balance pressure drilling process, belongs to the manufacturing technology field of gas drilling well site sediment outflow equipment.
Background technology:
In order to accelerate the development rate of petroleum gas, taked a lot of ways in the drilling technology field, wherein under balance pressure drilling is exactly a kind of preferably high-speed drilling technology, in under-balanced drilling technology, adopting gas is a kind of preferably method as the drilling well medium, the advantage of gas drilling is to increase substantially bit speed, owing to do not have under the liquid input well, so the problem of leakage does not take place yet, for the stratum that leakage may take place, administer the good method of leakage beyond doubt, simultaneously, because the proportion of gas is very light, in the process of implementing drilling well, can not invade the stratum, can not damage, so can well protect and find oil-gas Layer layer of oil gas production yet; The shortcoming of prior art is: because what taken out of by gas from the down-hole when implementing gas drilling is not mud, but by chippy rock sand, these rock sands have very big wearing and tearing to the sediment outflow pipe, environment there is bigger harm, in order in the process of implementing gas drilling, to guarantee safety and free from environmental pollution, often before gas drilling, the time that erection equipment and preparation are consumed is longer, wherein, in order to solve the problem that gas drilling row sand tube line is punctured by the rock sand wearing and tearing, very heavy with the sediment outflow pipe design, and the joint of tie point all adopts flange to connect, only be to connect these sediment outflow pipelines just to need 1 day time, what have also needs time of two days, and the heavy and difficulty of connection work.
Summary of the invention:
The purpose of this utility model is the problem that exists at prior art, adopts high-abrasive material to make the sediment outflow pipeline, reduces the weight of row's sand tube line, has designed a kind of row's sand tube line that is applicable to gas drilling that can connect fast.
The utility model is achieved in that the utility model comprises clip device and pipeline, is characterized in that: described clip device comprises front band 1 and lower catch hoop 7, is respectively arranged with upper and lower clip arm at the two ends of front band 1 and lower catch hoop 7; Pipeline comprises pipe shaft 10 and joint 11, and the back side of joint 11 is ramp structures, and front band 1 is connected by bolt 2 with lower catch hoop 7;
Described lower catch hoop arm 5b is provided with the pin hole;
Described front band arm 5a is provided with lock hole 4;
The lower end of described bolt 2 is fixed in the pin hole of lower catch hoop 7 by pin 8;
The interior circle of described front band 1 and lower catch hoop 7 is provided with the groove that the ramp structure with joint 11 back sides adapts;
When making pipeline and joint 11 thereof, adopt the inner surface of high-abrasive material butt joint 11 and sediment outflow pipeline to handle, make joint 11 and sediment outflow pipeline inner surface have the advantages that anti-sand washes away, when the sediment outflow pipeline is installed at the scene, two pipeline front ends are closed up, like this, the ramp structure at two pipe joint 11 back sides that close up has just formed can realize that the protrusion that connects is stupefied, to go up, lower catch hoop 1 and 7 is respectively from protruding stupefied snapping in up and down, to go up by bolt 1 again, lower catch hoop connects, and it is fixing by nut 3, last putting in lock hole 4 locks the connection that card 9 has just been finished one section sediment outflow pipe joint, just can come into effect gas drilling after whole pipe joints connections are finished.
Advantage of the present utility model with beneficial effect is: the ramp structure that is provided with at two pipe joint back sides can form very easily after two pipelines butt joints that to be connected protrusion stupefied, last, on the protrusion that the interior round groove that is provided with of lower catch hoop can be stuck in tie point formation fast is stupefied, and by the quick fixed connection point of bolt, therefore, realized that syndeton is simple, cost is low, and the purpose of convenient processing and manufacture, the cure process of joint and sediment outflow pipeline inner surface can play wear-resisting effect, therefore can reduce the wall thickness of pipeline, the weight of the row's of making sand tube line reduces significantly, move and be connected also just convenient and swiftly, can increase substantially the on-the-spot efficient that connects construction.

The specific embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
The utility model comprises clip device and pipeline, the clip device is two semicircle devices, constitute by front band 1 and lower catch hoop 7, in order to connect the upper and lower clip of two semi-circular structure, two ends at front band 1 and lower catch hoop 7 are respectively arranged with clip arm 5a and 5b, the interior circle of front band 1 and lower catch hoop 7 is provided with groove, and the groove of setting can be stuck on the joint of pipeline easily, is convenient to realize the connection of two pipelines; Pipeline comprises pipe shaft 10 and joint 11, the front of joint 11 is plane structures, be convenient to the butt joint of two pipelines, the back side of joint 11 is ramp structures, the ramp structure that is provided with after two pipelines butt joints, can form with upper and lower clip in the protrusion that adapts of the groove that is provided with on the circle stupefied, be convenient to snapping in of front band 1, lower catch hoop 7; The lower catch hoop arm 5b that is provided with is provided with pin hole 8, is connected with bolt 2 by pin 6 in pin hole 8, and front band 1 is connected by bolt 2 with lower catch hoop 7; For the sake of security, on front band arm 5a, also be provided with lock hole 4 and locking card 9;
When making pipe shaft 10 and joint 11 thereof, can all adopt wear-resisting material, also can butt joint 11 and the inner surface of pipe shaft 10 carry out Wear-resistant Treatment, make the inner surface of joint 11 and pipe shaft 10 have the advantages that anti-sand washes away, when the sediment outflow pipeline is installed at the scene, two pipe shaft 10 front ends are closed up, like this, the ramp structure at two pipe shafts, 10 front tab, 11 back sides that close up has just formed can realize that the protrusion that connects is stupefied, to go up, lower catch hoop 1 and 7 is respectively from protruding stupefied snapping in up and down, to go up by bolt 2 again, lower catch hoop connects, and it is fixing by nut 3, last, after lower catch hoop 1 and 7 installs, to lock card 9 inserts from lock hole 4, can play the problem that prevents that bolt 2 from coming off automatically because of the pipeline vibrations, thereby improved security reliability, when mounted, if the aligning surface of two pipelines differs when a less angle is arranged, can utilize, lower catch hoop 1 and 7 slowly snaps in, calibrate, finally reach the purpose of aiming at fully, thereby it is more convenient that installation is connected, after whole pipe joints connections are finished, just can come into effect gas drilling.
