Description

Technical Field

[0001] The present invention relates to the field of oilfield workover operations, and particularly to an intelligent, safe and environmentally friendly tubing bridge box. Background Art

[0002] At present, during the construction of tubing running and pulling in the oilfield workover operation site, a kind of bridge seat is usually used, which is commonly known as a tubing bridge on site. When performing a workover operation, conventional tubing running and retrieving operations are required. The traditional mode is to use three tubing bridges as the base, and the tubing is neatly arranged in layers on the tubing bridges. The tubing is transported or retrieved to or from the wellhead platform manually. There are two ways to transport or retrieve the tubing: one is to use two tubings as slide rails and use a small trolley to transport the tubing. The other is to use a tubing conveyor. The operator manually moves the tubing to the small hook of the conveyor. The small hook lifts the tubing and flips it to the chute of the tubing conveyor, and then transports the tubing to the wellhead.

[0003] This traditional operation mode has the following disadvantages: (1) Environmental protection problems: The area of the tubing bridge is at least 120 square meters. In order to prevent the crude oil and sewage in the tubing from falling to the ground, a large-area anti-oil plastic cloth and fences need to be laid under it. This not only has a high cost but is also easily damaged. If reused, the cleaning is very cumbersome. In addition, since the tubing is in an open space, when using a boiler truck to clean the tubing, the steam will carry the oil stain and disperse to pollute the environment. (2) Safety problems: When moving the tubing, workers need to stand on the tubing row and roll the tubing forward one by one manually. The handling efficiency is low and the labor intensity of the workers is high. Since the tubing is attached with crude oil, it is very easy to slip and step on the air, posing a huge safety hazard. Summary of the Invention

[0033] Specifically, the number of the support frames 17 is 4. Two symmetrically arranged support frames 17 form a support mechanism to support the main support rod 18 and the sub-support rod 14.

[0034] Taking one group of support mechanisms as an example for detailed description, as Figure 2 shown, the support mechanism is composed of two symmetrically arranged support frames 17. The main support rod 18 is longitudinally arranged in the box body 1, and both ends of the main support rod 18 are installed in the support frames 17. A plurality of sub-support rods 14 are longitudinally arranged in the box body 1, and both ends of the sub-support rods 14 are installed in the support frames 17. The sub-support rods 14 are located above the main support rod 18. Through the main support rod 18 and the sub-support rods 14, the tubing can be neatly arranged in layers in the tubing bridge box.

[0035] In order to prevent the tubing 2 from rolling off both sides of the box body 1, a stop block 11 is provided on one side of the box body 1, and a limit retaining platform 5 is provided on the other side of the box body 1.

[0036] As Figure 4 and Figure 6 shown, a slot 111 is provided at the bottom of the stop block 11, and the stop block 11 is inserted into the box body 1 through the slot 111.

[0037] As Figure 5 and Figure 7As shown, a clamping groove 52 is provided on one side of the limit retaining platform 5, and a limit baffle 51 is provided on the other side of the limit retaining platform 5. The limit retaining platform 5 is clamped on the support frame 17 through the clamping groove 52, and the oil pipe 2 is blocked by the limit baffle 51.

[0038] As Figure 5 shown, the support frame 17 is provided with a notch 25 for placing the square cushion block 15 and holes 24 for inserting the round steel 19. There are several such holes 24, and they are equally spaced on both sides of the support frame 17.

[0039] As Figure 1 shown, four jacks 10 are provided on the box body 1. The four jacks 10 are respectively arranged at the bottom of the support frame 17. Through the jacks 10, the main support rod 18 and the auxiliary support rod 14 can be jacked up, and then the oil pipe 2 can be transported.

[0040] As Figure 5 、 Figure 8 、 Figure 9 and Figure 10 shown, the jack 10 includes a cylinder block 101, a large piston rod 102 and a small piston rod 103. The cylinder block 101 is provided with an oil pipe interface 107 and an air pipe interface 108. The oil pipe interface 107 is connected to the hydraulic oil outlet of the hydraulic tank 13 through the oil pipe 21, and the air pipe interface 108 is connected to the gas outlet of the hydraulic tank 13 through the air pipe 22. The large piston rod 102 is installed in the cylinder block 101 and can move up and down along the cylinder block 101. A cavity is provided inside the large piston rod 102, and the small piston rod 103 is installed in the cavity and can move up and down along the large piston rod 102. A cushion block 104 is provided on the small piston rod 103.

[0041] A fixed seat 106 is provided at the bottom of the cylinder block 101, and the fixed seat 106 is fixedly connected to the box body 1 through bolts. Handrails 105 are provided on both sides of the cylinder block 101. To prevent rainwater and sundries from entering and affecting the operation of the jack 10, a protective door 23 is provided on the box body 1 near the jack 10.

[0042] As Figure 1 、 Figure 3 and Figure 11 shown, two air pipe collectors 7 are provided on the box body 1. The two air pipe collectors 7 are respectively located on both sides of the box body 1, and the air inlets of the air pipe collectors 7 are respectively connected to the air source of the workover rig. Four air storage tanks 8 are provided on the box body 1. The air inlets of two of the air storage tanks 8 are connected to the air outlets of one air pipe collector 7, and the air inlets of the other two air storage tanks 8 are connected to the air outlets of the other air pipe collector 7. Four control valves 27 are provided on one side of the box body 1, and each control valve 27 corresponds to one jack 10, so as to control the lifting operation of the piston rod of the jack 10.

[0043] Each control valve 27 is provided with an air inlet and two air outlets. The air inlets of the control valves 27 are respectively connected to the air outlets of the corresponding gas storage tanks 8 through air pipes, and the air outlets of the control valves 27 are respectively connected to the air inlets of the corresponding hydraulic tanks 13 through air pipes. An operating handle is provided on the control valve 27. By moving the operating handle to the left, to the middle or to the right, the piston rod of the jack 10 can be controlled to rise, stop and fall. The number of hydraulic tanks 13 is 4. An oil filling port is provided above the hydraulic tank 13, and oil can be injected into the hydraulic tank 13 through the oil filling port.

[0044] A safety valve, a pressure gauge and a drain valve are provided on the gas storage tank 8. When the pressure in the gas storage tank exceeds 1.6 MPa, the safety valve automatically opens and then discharges fully. When the pressure drops to 1.6 MPa, the safety valve automatically closes to ensure the safe operation of the equipment.

[0045] The pressure gauge is used to indicate the current pressure of the gas storage tank, and its measuring range is 2.5 MPa. After the gas storage tank operates, water will accumulate at the bottom of the tank. When the temperature is relatively low, the accumulated water will freeze and block the pipeline, causing serious consequences. Therefore, after each use, the drain valve must be opened to drain the water completely.

[0046] Supports 12 are provided on both sides of the box body 1. The supports 12 are used to place the auxiliary support rods 14. The supports 12 include a cross bar 121 and a plurality of stop bars 122 provided on the cross bar 121. One end of the stop bar 122 is connected to the cross bar 121, and the other end of the stop bar 122 extends upward with a bent portion 1221.

[0047] A box door 6 is provided at one end of the box body 1. Through the box door 6, the oil pipe can be flushed, the pipe thread protector of the oil pipe can be disassembled, and the inside of the box body 1 can be cleaned. Storage boxes 16 for placing square cushion blocks 15 and round steel 19 are provided on both sides of the box body 1. Lifting feet 9 are also provided on both sides of the box body 1.

[0048] As Figure 1 and Figure 2 shown, an ultrasonic measuring device is provided on the box body 1. The length of the oil pipe can be measured through the ultrasonic measuring device. The ultrasonic measuring device includes a head sub-machine 3 and a tail sub-machine 4. The head sub-machine 3 and the tail sub-machine 4 are fixed at both ends of the box body 1 through a fixing frame 28. The head sub-machine 3 and the tail sub-machine 4 are arranged on one side close to the limit retaining table 5. The head sub-machine 3 and the tail sub-machine 4 are respectively connected to the main control machine through cables.

[0049] The head slave unit 3 includes a chassis, an ultrasonic distance sensor and a circuit board installed in the chassis. The chassis is fixed to one end of the box body 1 through a fixing bracket 28. The ultrasonic distance sensor is electrically connected to the circuit board. It receives the ultrasonic instruction sent by the master unit through the RS485 module on the circuit board. After the single-chip microcomputer on the circuit board discovers and interrupts the instruction at the serial port, it controls the ultrasonic distance sensor to emit sound waves. The ultrasonic distance sensor sends the measured data to the single-chip microcomputer on the circuit board. The single-chip microcomputer sends multiple data measured by the ultrasonic distance sensor to the master unit through the serial port mode, and the master unit reads the data.

[0050] The tail slave unit 4 includes a chassis, an ultrasonic distance sensor, a laser distance sensor and a circuit board installed in the chassis. The chassis is fixed to one end of the box body 1 far from the head slave unit 3 through a fixing bracket 28. The ultrasonic distance sensor and the laser distance sensor are respectively electrically connected to the circuit board. It receives the ultrasonic instruction sent by the master unit through the RS232 module on the circuit board. After the single-chip microcomputer on the circuit board discovers and interrupts the instruction at the serial port, it controls the ultrasonic distance sensor to emit sound waves. The ultrasonic distance sensor sends the measured data to the single-chip microcomputer on the circuit board. The single-chip microcomputer sends multiple data measured by the ultrasonic distance sensor to the master unit through the serial port mode, and the master unit reads the data. It receives the laser instruction sent by the master unit through the RS232 module on the circuit board. After the single-chip microcomputer on the circuit board discovers and interrupts the instruction at the serial port, it controls the laser distance sensor to emit laser. The laser distance sensor sends the measured data to the single-chip microcomputer on the circuit board. The single-chip microcomputer sends multiple data measured by the laser distance sensor to the master unit through the serial port mode, and the master unit reads the data.

[0051] When the oil pipe 2 rolls onto the limit retaining platform 5 (see Figure 2 ), after waiting for the oil pipe 2 to stabilize and stop shaking, it is measured simultaneously by the ultrasonic distance sensors of the head slave unit 3 and the tail slave unit 4. The ultrasonic distance sensor of the head slave unit 3 measures the distance between the head slave unit and the head of the oil pipe, and the ultrasonic distance sensor of the tail slave unit 4 measures the distance between the tail slave unit and the tail of the oil pipe. Then, the laser distance sensor of the tail slave unit measures the distance between the head slave unit 3 and the tail slave unit 4. The measured data is transmitted to the master unit through the serial port mode by the head slave unit and the tail slave unit respectively. After the master unit performs corresponding processing and reads the data, it calculates the effective length of the oil pipe. The effective length of the oil pipe is: L﹦A﹣T﹣W﹣S±Z; where A is the numerical value of the distance between the head slave unit and the tail slave unit, T is the numerical value of the distance between the head slave unit and the head of the oil pipe, W is the numerical value of the distance between the tail slave unit and the oil pipe, S is the numerical value of the length of the male thread at the tail of the oil pipe, and Z is the correction value (error value).

[0052] When conveying the oil pipe 2, the side of the box body 1 with the limit stop 5 is placed close to the oil pipe conveyor, and the operating handle of the control valve 27 is turned to the left to extend the piston rod of the jack 10, and the main support rod 18 and multiple auxiliary support rods 14 are lifted upward, so as to lift the first layer of the oil pipe 2. When conveying the oil pipe, the two jacks 10 away from the side of the limit stop 5 can be raised a little more to make the main support rod 18 and the auxiliary support rod 14 slightly tilted, so that the oil pipe 2 can be better rolled onto the limit stop 5, and the oil After the pipe 2 rolls down onto the limit stop platform 5, the limit stop block 51 of the limit stop platform 5 stops the oil pipe 2. After the oil pipe is stable, the length of the oil pipe 2 is measured by the ultrasonic measuring device. After the measurement is completed, the small hook on the oil pipe conveyor lifts the oil pipe 2 and turns the oil pipe 2 into the V-shaped conveying groove of the oil pipe conveyor. The conveying groove is driven to lift and move forward through the control system to deliver the oil pipe 2 to the wellhead, and then the oil pipe 2 is lifted by the big hook of the well repair rig and sent into the well, thereby completing the transportation of the oil pipe.

[0053] After the first layer of oil pipe 2 is transported, the round steel 19 is inserted into the first hole 24 (the hole 24 at the bottom of the support frame 17) of the support frame 17 to hold the main support rod 18, and the operating handle of the control valve 27 is turned rightward to retract the piston rod of the jack 10. The uppermost auxiliary support rod 14 is taken out and placed on the bracket 12, and then the square pad 15 is placed in the notch 25 of the support frame 17, and the operating handle of the control valve 27 is turned leftward to extend the piston rod of the jack 10, and the square pad 15 is lifted upward, and then the main support rod 18 and multiple auxiliary support rods 14 are lifted upward to lift the second layer of oil pipe 2 and transport it. After this layer is completed, the round steel 19 inserted in the first hole 24 can be pulled out and inserted into the second hole 24 to hold the main support rod 18. When the third layer of oil pipe is transported, the piston rod of the jack 10 is retracted, and another square pad 15 is stacked on the square pad 15 to transport the third layer of oil pipe. By stacking the square pads 15 layer by layer, and cooperating with the jacks 10 and the round steel bars 19, the transportation operation of the multi-layer oil pipes is completed in sequence.

[0054] During the operation of receiving the oil pipe, two main support rods 18 are located at the inner top of the box body 1 to receive the oil pipe entering the box body 1. At this time, the main support rod 18 is supported by the round steel 19 inserted into the hole 24 of the support frame. After the oil pipes are arranged, the operating handle of the control valve 27 is toggled to the left to extend the piston rod of the jack 10, which jacks up multiple square pads 15 stacked in the notch 25 upwards, so that the main support rod 18 bears force on the square pads 15, and the round steel 19 is pulled out. Then, the operating handle of the control valve 27 is toggled to the right to retract the piston rod of the jack 10, thereby driving the main support rod 18 and the retracted oil pipe 2 to move down one grid. Then, the round steel 19 is inserted into the next hole 24, so that the main support rod 18 bears force on the round steel 19, and then one square pad 15 in the support rod notch 25 is taken out. The two auxiliary support rods 14 are placed on the corresponding support mechanisms, and the operation of receiving the oil pipe continues. After the oil pipes are arranged, the operating handle of the control valve 27 is toggled to the left to extend the piston rod of the jack 10, which jacks up the square pads 15 upwards, so that the main support rod 18 bears force on the square pads 15, and the round steel 19 is pulled out. Then, the operating handle of the control valve 27 is toggled to the right to retract the piston rod of the jack 10, thereby driving the main support rod 18, the auxiliary support rod 14 and the retracted oil pipe 2 to move down one grid. The round steel 19 is inserted into the next hole 24, so that the main support rod 18 bears force on the round steel 19, and then one square pad 15 in the support rod notch 25 is taken out. Then, the two auxiliary support rods 14 are placed on the corresponding support mechanisms. According to this method, the oil pipes are arranged in layers neatly in the box body 1, and then the operation of receiving the pipes is completed.

[0055] During the operation of receiving the oil pipe, the two jacks 10 on one side close to the limit retaining table 5 can be lifted a little more, so that the main support rod 18 and the auxiliary support rod 14 are slightly inclined, which is convenient for the oil pipe 2 to roll into the box body 1.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
