Description

Drilling water-based mud transfer device with collection function

Technical Field

The utility model relates to a drilling construction technical field, concretely relates to drilling water base mud transfer device with collect function.

Background

Rock debris, water-based mud and other impurities are generated in the existing natural gas drilling construction. The water-based mud contains recyclable matters and the like, so that the water-based mud is necessary for collecting and treating the water-based mud after natural gas drilling.

In Chongqing, aiming at the position with the depth of thousands of meters, water-based mud (including water, mud and rock debris) needs to be conveyed from inside to outside, and then is collected, transported and disposed.

In the prior art, generally, water-based slurry is collected after passing through a feeding device, and is subjected to pretreatment by means of sedimentation, filter pressing and the like or directly transported to a unit with treatment capacity such as a brickyard without pretreatment for final treatment.

SUMMERY OF THE UTILITY MODEL

The purpose of this scheme is to provide the well drilling water base mud transfer device who has the function of collecting to water base mud transports the problem during the well drilling.

In order to achieve the above object, the present invention provides a drilling water-based mud transfer device with a collection function, comprising: the crushing drill comprises a motor, a mounting frame, a threaded sleeve and a crushing drill bit; the mounting rack is provided with a threaded sleeve fixedly connected with the mounting rack; a screw rod in threaded connection with the threaded sleeve is arranged in the threaded sleeve; the top of the screw is fixedly connected with an output shaft of the motor, and the bottom of the screw is fixedly connected with the crushing drill bit; and a hinged reamer is arranged in the crushing drill bit, and a torsional spring is arranged at the hinged position.

The principle of the scheme is as follows: place required position with the device, the starter motor for drive the screw rod when the motor drives the output shaft and rotate thereupon, and then make the broken drill bit in bottom rotate thereupon, the reamer under the effect of centrifugal force, and is outwards rotatory, and then makes the place that broken drill bit bored out. Meanwhile, the rotation of the reamer is utilized, so that the water-based slurry is not easy to dry and is convenient for subsequent collection.

The scheme has the beneficial effects that: this scheme utilization centrifugal force principle for the reamer is outside stretching out broken drill bit when using, during the inoperative, retracts to broken drill bit in, not only makes things convenient for follow-up recovery water base mud, can reduce the space of device moreover, prevents moreover that the reamer from hindering the user. Meanwhile, the motor is utilized to drive the screw rod to rotate, so that the screw rod moves downwards in the threaded sleeve, the distance of the extending part of the screw rod is increased, the screw rod reaches a deeper position in the well, and the applicability is wider.

Further, the mounting bracket outside is equipped with a plurality of fixed subassemblies with it and fixed connection, and fixed subassembly includes: the adjusting supporting legs, the telescopic rods and the fixing plates; the adjusting support legs are fixedly arranged on the outer side wall of the mounting frame; the bottom of the adjusting supporting leg is hinged to the top of the telescopic rod, and the bottom of the telescopic rod is hinged to the fixing plate. When the device is used, the fixing plate is placed at a required position and fixedly connected with the ground through the screw, and then the device can be fixedly installed. Simultaneously the telescopic link guarantees to the well of the different degree of depth, all can use, and the practicality is wider.

Further, the middle part of the screw rod is of a hollow structure; the top of the screw is provided with a mud suction pipe communicated with the screw; one end of the mud suction pipe is connected with mud suction equipment. During reamer initial state, inside retracting to broken drill bit, and then the opening that blocks the bottom of screw rod, when broken drill bit rotated, the reamer outwards rotated under the effect of centrifugal force, and then made screw rod bottom opening expose, started the mud sucking equipment this moment, and then by the garrulous water base mud of reamer ream along mud suction pipe suction outside to the well. The water-based mud is sucked out, so that the broken drill bit can work continuously to the deep position conveniently, the resistance of the water-based mud to the broken drill bit and the broken drill bit is reduced, the water-based mud is broken and absorbed simultaneously, the time cost is saved, and the manual follow-up work is saved.

Further, be equipped with between mounting bracket and the threaded sleeve and be used for absorbing damper, damper includes: a sleeve and a push rod; the sleeve is fixedly arranged inside the mounting frame; the sleeve is connected with the push rod in a sliding mode, and a spring is arranged between the push rod and the inner portion of the sleeve; a ball is arranged between the side wall of the push rod and the sleeve; the top end of the push rod props against the threaded sleeve. Starting at the motor, broken drill bit during operation certainly arouses vibrations, and damper prevents to guarantee not only that the top remains stable when broken drill bit stretches into in the well deepening, can not take place to rock, influences the well drilling process.

Detailed Description

The following is further detailed by way of specific embodiments:

the reference numbers in the drawings of the specification include: the device comprises a motor 1, a mounting frame 2, a threaded sleeve 3, a screw rod 4, a mud suction pipe 5, a crushing drill bit 6, a reamer 7, an adjusting supporting leg 8, a telescopic rod 9, a fixing plate 10, a positioning sleeve 11, a push rod 12, a spring 13 and balls 14.

As shown in figure 1:

drilling water base mud transfer device with collect function, including

mounting bracket

2, 2 outsides of mounting bracket are equipped with a plurality of fixed subassemblies with it and fixed connection, include: adjust landing leg 8, telescopic link 9 and fixed plate 10, adjust landing leg 8 fixed mounting on 2 outside lateral walls of mounting bracket, adjust landing leg 8 bottom and be equipped with articulated telescopic link 9, telescopic link 9 bottom is equipped with articulated fixed plate 10 with it, when using, places required position with fixed plate 10, through screw and ground fixed connection, and then guarantees that the device can fixed mounting. Simultaneously telescopic link 9 guarantees to the well of the different degree of depth, all can use, and the practicality is wider.

As shown in fig. 2:
