Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It can be appreciated that the injector head is a critical component of coiled tubing operations equipment, and whether the injector head is operating properly directly affects the entire coiled tubing operations process. When the injection head belt works in a failure mode or safety risks exist, accidents are easy to happen, and the consequences are extremely serious. However, during the operation, the injection head is far away from the ground, which is not convenient for the operator to observe in a short distance, so at present, the injection head is mainly inspected before the operation and maintained regularly to ensure the injection head to be in a reliable operation state. However, the inspection before operation or the regular inspection cannot realize the state monitoring during the operation of the injection head, so that the fault generated during the operation of the injection head cannot be found and processed in time, meanwhile, the inspection of the injection head mainly adopts a mode of visual observation and equipment operation sound listening, and the inspection mode mainly depends on the experience of operators, so that the requirement on the operators is high, and meanwhile, the state judgment of the injection head is completely based on the subjective opinion of the operators, and the condition judgment is lack of quantitative means, so that the misjudgment or the misjudgment is easy to occur.
Based on the above, the embodiment of the present invention provides a method for monitoring an injection head, which judges a working state of the injection head by monitoring a state parameter of the injection head obtained in real time during an operation process of the injection head, and gives an operation prompt and/or a fault alarm based on the working state of the injection head, thereby implementing monitoring of the operation state during the operation process of the injection head, facilitating timely problem finding and handling, effectively improving reliability of the operation of the injection head, and ensuring smooth operation.
A method of injector head monitoring of the present invention is described below in conjunction with fig. 1 and 2, as performed by a controller of the injector head or a combination of software and/or hardware therein, as shown in fig. 1, the method comprising the steps of:
101. acquiring state parameters of the injection head in the operation process in real time;
it should be noted that the injection head is a key component of coiled tubing operation equipment, a hydraulic motor capable of rotating in the forward and reverse directions drives a chain wheel to work, and the coiled tubing is clamped by virtue of a saddle-shaped clamping block between chain joints to move together with a chain, so that the coiled tubing is lowered into a well or lifted out of a wellhead. Therefore, in the operation process of the injection head, the rotating speed of the hydraulic motor, the running speed of the chain and the like are state parameters for representing the working state of the injection head.
102. Judging the working state of the injection head based on the state parameter;
specifically, based on the state parameters of the injection head in the operation process acquired in real time, the judgment of the working state such as whether the injection head is in fault or not can be realized.
103. And giving corresponding operation prompts and/or fault alarms based on the working state.
Specifically, the automatic judgment of the working state of the injection head based on the state parameters can be realized by acquiring the state parameters of the injection head in the operation process in real time, namely, the real-time monitoring of the running state of the injection head is realized, and compared with the inspection or the periodic inspection of the injection head before the operation, the fault of the injection head can be found more timely, meanwhile, compared with the manual inspection, the method is more objective and accurate, and the accuracy of monitoring the working state of the injection head is improved.
More specifically, after the working state of the injection head is obtained, operation prompts and/or fault alarms can be given according to different working states of the injection head, so that when the working state of the injection head deviates from the normal working state, an operator can perform timely operation processing on the injection head according to the operation prompts, timely processing when the problem of the injection head is found is realized, the running reliability of the injection head is effectively improved, and smooth operation is ensured. Meanwhile, compared with a manual inspection mode, the method avoids dependence on experience of operators, effectively overcomes limitation of manual inspection, and reduces possibility of missed inspection and misjudgment.
As an embodiment of the present invention, the status parameters include:
the stroke position of a clamping cylinder of a clamping system of the injection head;
the position of the driven sprocket of the tensioning system of the injection head;
the rotational speed of the driven sprocket.
It should be noted that the injector head is a key component of coiled tubing operation equipment, and has the main functions of clamping the tubing and overcoming the upward jacking force and friction force of the downhole pressure on the tubing string, lowering the coiled tubing into the well or clamping the coiled tubing immovably or pulling the coiled tubing out of the well, and controlling the injection and pulling-out speeds of the tubing. The injection head mainly comprises a rack, a driving system, a coiled tubing slip, a traction chain, a tensioning system, a clamping system, a load sensor and the like, and meanwhile, coiled tubing operation equipment is provided with a host machine for monitoring the actions of all the parts.
The main function of the frame is to install and fix the chain wheel, the hydraulic motor, the clamping system and other accessories on the injection head; a hydraulic motor of the driving system provides a power source for conveying the driving chain and the continuous oil pipe; the tensioning system and the clamping system mainly play a role in tensioning the chain and driving the slips to hold the coiled tubing tightly; the load sensor mainly plays a role in measuring the hanging weight of the oil pipe.
It will be appreciated that the injector head will typically stop working when the hydraulic motor fails; when the load sensor breaks down, the host computer generally can't obtain the measured value of oil pipe suspended weight, that is to say, based on the trouble of hydraulic motor and load sensor, can directly reflect in the operation of injection head, therefore, need not carry out real-time supervision.
Specifically, for the tensioning system and the clamping system, the tensioning chain and the driving slip are mainly used for holding the coiled tubing tightly, when the chain is not tensioned completely, the slip is not held tightly completely and the like, the situation that relative movement occurs between the coiled tubing and the slip, namely the coiled tubing slips, the injection head cannot stop operating can be caused, but the operation quality can be affected, the expensive coiled tubing is damaged, and meanwhile accidents can be caused, so that the tensioning system and the clamping system of the injection head need to be monitored in real time.
More specifically, the stroke position of the clamping oil cylinder can reflect the working state of the clamping system; the position of the driven chain wheel can reflect the use condition of the chain, and the rotating speed of the driven chain wheel can reflect whether the relative motion between the continuous oil pipe and the injection head occurs or not, namely whether the continuous oil pipe slips or not.
As an embodiment of the present invention, the determining the working state of the injector head based on the state parameter includes:
judging whether the clamping system operates normally or not based on the stroke position of the clamping oil cylinder;
judging whether the tensioning system operates normally or not based on the position of the driven chain wheel;
and judging whether relative motion occurs between the oil pipe and the injection head or not based on the rotating speed of the driven chain wheel.
Specifically, the clamping system pushes the slips to hold the oil pipe tightly through the clamping oil cylinder so as to drive the continuous oil pipe to move under the driving of the chain, so that when parts in the clamping system are worn and damaged, the stroke position of the clamping oil cylinder can be changed, and therefore, the purpose of monitoring whether the clamping system of the injection head operates normally or not can be achieved by monitoring the stroke position of the clamping oil cylinder of the clamping system of the injection head in real time.
The tensioning system is used for tensioning the chain, the chain can be elongated along with the use of the chain, and after the chain is elongated, the position of the driven chain wheel can be changed for achieving the purpose of tensioning the chain, so that the elongation of the chain can be reflected on the position of the tensioning system, and the operation condition of the tensioning system can be obtained by monitoring the position of the driven chain wheel.
Further, the main machine of the coiled tubing operation equipment collects the speed of the coiled tubing, so that the rotating speed of the driven sprocket should be matched with the speed of the coiled tubing collected by the main machine under the condition that the coiled tubing does not slip, and therefore, whether the coiled tubing slips relative to the injection head or not can be monitored by monitoring the rotating speed of the driven sprocket.
As an embodiment of the present invention, the determining whether a relative motion occurs between an oil pipe and the injector head based on the rotation speed of the driven sprocket includes:
obtaining the running speed of the chain of the tensioning system based on the rotating speed of the driven chain wheel;
and judging whether the relative motion occurs between the oil pipe and the injection head or not based on the running speed of the chain and the oil pipe speed of the oil pipe.
It will be appreciated that the injector head is a component of coiled tubing equipment for moving coiled tubing, the roller is also an important component of coiled tubing equipment for winding and unwinding coiled tubing, and is generally provided with an encoder for measuring the speed of the coiled tubing, and the host machine acquires the speed of the coiled tubing by collecting data from the encoder, so that the running speed of the chain should be matched with the speed of the coiled tubing when the coiled tubing is not moving relative to the injector head, i.e. not slipping.
Based on the above, when the rotating speed of the driven chain wheel is obtained, the running speed of the chain is obtained, and whether the oil pipe slips relative to the injection head or not can be reflected by comparing the running speed of the chain with the oil pipe speed obtained by the main machine from the roller.
As an embodiment of the present invention, the giving of the corresponding operation prompt and/or the fault alarm based on the working state includes:
when the cylinder piston of the clamping cylinder moves inwards relative to the cylinder body beyond a preset first position, giving an operation prompt for increasing the clamping pressure of the clamping system;
when the cylinder piston of the clamping cylinder moves outwards relative to the cylinder body and exceeds a preset second position, giving a fault alarm of abnormal stroke position of the clamping cylinder, and checking the abrasion condition of parts forming the clamping system and an operation prompt of whether a clamping cylinder connecting bolt of the clamping system is fastened;
when the position of the driven chain wheel deviates upwards relative to a preset normal position, giving an operation prompt for increasing the tension;
when the position of the driven chain wheel deviates downwards relative to the normal position within a preset time length, giving an operation prompt of chain abnormity and shutdown inspection;
when the position of the driven chain wheel deviates downwards relative to the normal position and exceeds a preset displacement threshold value, giving an operation prompt that the chain needs to be scrapped and replaced;
and when the difference value between the running speed of the chain and the oil pipe speed of the oil pipe is greater than a preset speed threshold value, giving out a fault alarm that relative movement occurs between the oil pipe and the injection head, and giving out an operation prompt for increasing the clamping pressure.
Specifically, the position of the cylinder piston of the clamping cylinder relative to the cylinder body influences the stroke position of the clamping cylinder, so that the stroke position of the clamping cylinder can be obtained according to the position of the cylinder piston relative to the cylinder body, and whether the clamping system operates normally can be further judged, and the cylinder piston moves inwards and outwards relative to the cylinder body, so that the inward movement and the outward movement of the cylinder piston relative to the cylinder body are respectively considered.
More specifically, when the inward movement of the cylinder piston of the clamping cylinder relative to the cylinder body exceeds a preset first position, the clamping pressure of the coiled tubing is insufficient, and an operation prompt for increasing the clamping pressure of the clamping system is given, so that an operator can adjust the holding force of the coiled tubing in time; giving an operation prompt to increase the clamping pressure of the clamping system; and when the cylinder piston of the clamping cylinder moves outwards relative to the cylinder body to exceed a preset second position, which indicates that the parts of the clamping cylinder are worn or misplaced, a fault alarm of abnormal stroke position of the clamping cylinder is given, and an operation prompt for checking the wear condition of the parts forming the clamping system and whether a clamping cylinder connecting bolt of the clamping system is fastened is given.
It should be noted that the first position and the second position are preset according to the specific situation of the clamping cylinder, and are not necessarily the same for different clamping cylinders, so that the specific numerical value is not limited herein.
Further, when the position of the driven chain wheel deviates upwards relative to a preset normal position, the tension of the chain is insufficient, and an operation prompt for increasing the tension is given, so that an operator can adjust the tension of the chain in time; when the position of the driven chain wheel deviates downwards relative to the normal position within a preset time length, namely when the tensioning chain wheel moves downwards within a short time and exceeds a preset threshold value, indicating that the chain is abnormal, giving an operation prompt of abnormal chain and shutdown check, so that an operator can shut down the chain to check the chain in time to avoid accidents; when the position of the driven chain wheel deviates downwards relative to the normal position and exceeds a preset displacement threshold value, the chain elongation is shown to exceed the adjustable range of the tensioning system, and at the moment, an operation prompt that the chain needs to be scrapped and replaced is given, so that an operator can replace the chain in time to ensure the normal and safe operation of the injection head; and when the difference value between the running speed of the chain and the oil pipe speed of the oil pipe is greater than a preset speed threshold value, indicating that the oil pipe slips seriously, giving a fault alarm that relative movement occurs between the oil pipe and the injection head, and increasing the clamping pressure to prompt an operator to adjust the clamping pressure of the continuous oil pipe, so that the continuous oil pipe is prevented from slipping, and the operation quality is ensured.
It should be noted that the positions of the driven sprockets are in opposite directions relative to the upper and lower positions in the upward or downward offset from the preset normal position, and it is not specific that the upper position is at a high position, and the lower position is at a low position; wherein, the upward deviation indicates that the driven sprocket shifts towards the direction of being close to the tensioning oil cylinder, and the downward deviation indicates that the driven sprocket shifts towards the direction of keeping away from the tensioning oil cylinder.
As an embodiment of the present invention, after giving an operation prompt to increase the clamping pressure when the cylinder piston of the clamping cylinder moves inward with respect to the cylinder body beyond a predetermined first position, the method further includes:
acquiring the stroke position of the clamping oil cylinder after the operation of increasing the clamping pressure to obtain a new stroke position;
judging whether the new travel position is abnormal or not;
and when the new stroke position is abnormal, giving out a fault alarm of the abnormal position of the clamping oil cylinder and an operation prompt of stopping to check the condition of the clamping system.
Specifically, after the operator increases the clamping pressure according to the operation prompt, the operator can monitor the injection head after the clamping pressure is adjusted by continuously judging whether the new stroke position of the clamping oil cylinder is abnormal, so as to further ensure the reliable operation of the injection head.
More specifically, when the new stroke position of the clamping oil cylinder is still abnormal, the problem of insufficient clamping pressure still cannot be solved by increasing the clamping pressure, and at the moment, a fault alarm is given, and an operation prompt for stopping to check the condition of the clamping system is given, so that an operator can perform further definite check on the clamping system to ensure the use safety of the injection head.
It should be noted that, as shown in fig. 2, a step diagram of monitoring each part of the injection head, which needs to be monitored in real time during the operation process, by the injection head monitoring method according to the embodiment of the present invention is given in combination with an internal structural schematic diagram of the injection head.
Specifically, the injection head monitoring method mainly comprises the following steps: clamp system monitoring 201, tension system monitoring 202, and injector head speed monitoring 203.
More specifically, the clamping system monitoring step 201 again comprises the following steps:
211. analyzing the position of the clamping system;
221. and (4) abnormal position of the clamping system, increasing the clamping pressure or checking each part of the clamping system.
The tensioning system monitoring step 202 in turn comprises the steps of:
212. analyzing the position of the tensioning system;
222. detecting that the tensioning system moves downwards in a short time, and stopping to inspect the chain;
232. when the tensioning system is detected to move downwards to exceed the displacement threshold value, the chain is replaced;
242. the tensioning system is detected to move upwards and the tensioning force is insufficient.
The injector head speed monitoring step 203 in turn comprises the steps of:
213. comparing and analyzing the speed of the injection head and the speed of the roller;
223. the large difference in velocity between the roller and the injector head indicates slippage and requires increased clamping pressure or a shutdown to check the clamping system.
Therefore, the injection head monitoring method provided by the embodiment of the invention can monitor the operation state of the injection head in real time in the operation process of the injection head, so that the problem can be timely treated when the problem is found, and the smooth operation is ensured; through analyzing the acquired data, an abnormal alarm is found, and an operation instruction is given, so that the operators can deal with different problems in a targeted manner, the problem handling efficiency is improved, and the smooth and efficient operation is guaranteed; compared with a manual inspection mode, the possibility of missed detection and misjudgment is reduced; meanwhile, the state of the operation process is digitalized, and remote fault removal is easy to realize.
In the following, a monitoring system for an injector head according to the present invention is described, and a monitoring system for an injector head described below and a monitoring method for an injector head described above may be referred to with each other.
