Abstract
The technical field of the present invention belongs to " Oil and Natural Gas Engineering ".Its content invented is mainly used in " oil drilling " engineering skill.Ultrasonic sensor for the mud level in fixed and regulation measurement drilling mud jug.Mud level in the drilling mud jug of oil drilling scene, it can indirectly reflect the early stage omen of the drilling failure such as " blowout ", " leakage ".It is therefore possible to use the ultrasonic sensor that is placed at slurry tank top surface deck detects the change of liquid level.And in order to which fixed and regulation ultrasonic sensor is, it is necessary to there is an adjusting means that grips that can be conveniently and quickly installed at slurry tank top surface deck to carry out mounting ultrasonic sensor.Present disclosure is just devices which that it uses stainless steel material welding manufacture, have it is simple in construction, can easily be accommodated, be corrosion-resistant, corrosion protection feature, can conveniently be arranged on slurry tank top surface deck at, to grip and adjust sensor.
Description
Technical field
The technical field of the present invention belongs to " Oil and Natural Gas Engineering ", and its content of the invention is mainly used in " oil drilling " work
Journey technical scope.Ultrasonic sensor for the mud level in fixed and regulation measurement drilling mud jug.
Background technology
Drilling mud is generally deposited using irony rectangle slurry tank in oil drilling scene.Drilling mud is to carry out oil
Drilling well produces essential working media, is oil drilling " blood ".It participates in the circulation in well, has cutting carring,
Drill bit is cooled down, the strata pressure in pit shaft is balanced, prevents the functions such as cave-in.Especially when appearance " blowout ", " leakage " etc.
During drilling failure, obvious fluctuation up and down will occurs in liquid level of the drilling mud in slurry tank.Therefore, can be joined by detecting
" blowout " or " leakage " is predicted with the liquid level of the mud in the slurry tank of circulation, this safety drilling to oil drilling scene has
It is of great significance.
In order to effectively detect the liquid level of mud, can using the ultrasonic sensor being placed at slurry tank top surface deck come
Detect liquid level distance.And in order to which fixed and regulation ultrasonic sensor is, it is necessary to there is one can conveniently and quickly be installed on slurry tank
The adjusting means that grips at top surface deck carrys out mounting ultrasonic sensor.
The content of the invention
Originally adjusting means is gripped to be mainly used in gripping ultrasonic liquid level sensor.Enable at liquid level sensor
In a correct position, so as to measure the liquid level position in slurry tank (or distance).
Whole clamping device is divided into 3 parts, i.e., 1. adjusting rod (Fig. 1)；2. outer barrel (Fig. 2)；3. base (Fig. 3)；Its is each
Partial function is as follows：
1. adjusting rod
Adjusting rod be used for adjust sensor emission identity distance from mud jar liquid surface with a distance from.Sensor can use 4 bolt connections
Onto the bottom plate of adjusting rod, connecting cable may pass through the mesopore of adjusting rod and be connected with the switch board of distant place；
2. outer barrel
Outer barrel can accommodate sensor, and adjusting rod passes through outer barrel mesopore, and is fixed by the fixing screws on outer barrel mesopore；Unclamp
This fixing screws, can be by adjusting rod as suitable position, then the screw that is tightened；
3. base
Base is used for the steel plate for connecting slurry tank top surface；After base is fixed on the steel plate of slurry tank top surface (on steel plate
One and base inner circle circular hole of the same size should be opened, to allow the beam of sound of sensor emission to pass through), outer barrel can be placed on base
On, using two screws on outer barrel barrel, outer barrel can be firmly fixed to (or clamping) to base；

Embodiment
The device of the present invention manufactures using stainless steel material is welded with machining.
(1) install
1) connected the sensor to first with 4 bolts on the bottom plate of adjusting rod, pad upper gasket, sensor is had with bottom plate
One suitable interval, the cable of sensor is reconnected, makes cable through sensor and bottom plate interval, and from adjusting rod
Mesopore passes；
2) at the correct position of slurry tank top surface steel plate, a circular hole with base inner circle with size, blending bolt are opened
Base and slurry tank top surface steel plate are connected；
3) adjusting rod is passed through into outer barrel, sensor is placed in outer barrel, then outer barrel is placed on base, screwed on outer barrel
Two screws, outer barrel is set to be fixed on base；Adjust the position of adjusting rod manually again, sensor emission face is in suitable position
Put (sensor emission identity distance suitable from liquid level in slurry tank (face) with a distance from), then screw the screw at outer barrel mesopore, make regulation
Bar is fixed；
The assembling schematic diagram of the device is as shown in Figure 4.
The device is shown in oil drilling site installation test such as Fig. 5 (a), Fig. 5 (b).
(2) application notice
1) initial position of sensor distance liquid level can be adjusted by adjusting rod, and position can use the bolt on outer barrel after determining
It is fixed；
2) in mounting seat, pay attention to holding bolt nut properly, in case bolt nut is fallen into mud pit accidentally；
3) one week it is detachable over cylinder, cleaning or wipe the steam one of sensor surface to twice；
4) length of adjusting rod can determine according to actual conditions；
5) because adjusting rod bottom plate catercorner length is more than base inner diameter, it is not necessary to worry that sensor is fallen into mud pit.
