Description

Technical Field

[0001] The present invention belongs to the technical field of oilfield drilling, and relates to a visualization centralized control system for a solids control process. The present invention also relates to a visualization centralized control method. Background Art

[0002] With the continuous development of oil drilling and production equipment, automated and intelligent equipment has become the main trend of current development. However, the control of the solids control system has not achieved synchronous development with oil drilling and production equipment.

[0003] Traditional solids control systems have low automation levels, consume a large amount of manpower, and have low work efficiency. The equipment involved is basically all locally manually controlled. For example, valves need to rotate the handle and cooperate with an opening display instrument to accurately adjust the valve opening. The mud gun needs to manually press the switch to clean the tank wall. The agitator needs to be controlled to start and stop at a local operation column or electrical control room. In addition, there are a large number of mud tanks, and the supporting equipment on the tank surface is numerous and scattered. 3 - 5 operators often need to shuttle between various valves and equipment to adjust the on - off state or opening size of the valves, operate the start and stop of the equipment, and monitor the operating status of the equipment. The mud workers need to regularly sample the mud to detect its density and viscosity, prepare mud performance parameter reports, record the mud level, and adjust the addition amount of chemicals and solids. Summary of the Invention

[0004] The purpose of the present invention is to provide a visualization centralized control system for a solids control process, which solves the problem in the prior art that electric equipment cannot be remotely and centrally controlled.

[0005] Another purpose of the present invention is to provide a visualization centralized control method.

[0006] The technical solution adopted by the present invention is that the visualization centralized control system for a solids control process includes a switch, which is communicatively connected to a controller, a touch screen or an industrial control computer, a sensor data acquisition system, and multiple slave stations. Each slave station is electrically connected to multiple electric devices.

[0007] The characteristics of the present invention also lie in:

[0008] The switch is used for the transfer between the controller, the touch screen or the industrial control computer, the sensor data acquisition system, and the slave stations; the controller is used for sequential control, operation control, time control, data processing and operation, and communication; the touch screen or the industrial control computer is used for remotely and centrally controlling the electric devices and displaying the operating status of the electric devices; the slave stations are used for expanding I / O modules, collecting the operating status of the electric devices, sending the collected data to the controller and the touch screen or the industrial control computer, receiving the commands issued by the controller, and controlling the electric devices to act; the electric devices are terminal actuators, which can receive control commands and at the same time feedback the operating status to the I / O module of the slave station.

[0009] A communication interface for the centralized control system of the drilling rig is reserved on the switch.

[0010] The sensor data acquisition system is used to collect data from speed sensors, liquid level sensors, viscosity sensors, and density sensors.

[0011] Another technical solution adopted by the present invention is a visualization centralized control method, which is specifically implemented according to the following steps:

[0013] Step 2: Draw a general flow chart on the touch screen or industrial control computer according to the drilling process;

[0014] Step 3: Set a control mode selection switch on the general flow chart of the touch screen or industrial control computer, and set start / stop buttons next to each legend on the general flow chart;

[0015] Step 4: Execute the corresponding process according to the control mode selected in Step 3.

[0016] The characteristics of another technical solution of the present invention also lie in:

[0017] Step 1 is specifically: Write a control program in the controller, and the control program includes a manual control function and multiple process control functions.

[0018] Step 3 is specifically: Set a control mode selection switch on the general flow chart of the touch screen or industrial control computer. The control mode selection switch is divided into a device manual control gear, a process manual control gear, and a process automatic control gear, and start / stop buttons are set next to each legend on the general flow chart.

[0019] Step 4 is specifically: The control mode selection switch defaults to the device manual control gear. When the gear is switched, a gear confirmation prompt box will pop up. After clicking the confirmation, the function corresponding to the gear will be called;

[0020] Step 4.1: When the control mode selection switch is in the device manual control gear, call the manual control function in the controller. The start / stop buttons next to the legends on the general flow chart of the touch screen or industrial control computer will appear, and then click the start / stop buttons next to the legends one by one to control the start or stop of the corresponding electric equipment. According to the start / stop position of the button and the background color of the legend, obtain the operating status of the current electric equipment;

[0021] Step 4.2: When the control mode selection switch is in the process manual control gear, the start / stop button next to the legend on the overall flow chart of the touch screen or industrial control computer automatically hides, and control buttons for multiple sub-processes appear.

[0030] The present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0031] The solids control process visualization centralized control system, as Figure 1As shown in the figure, it includes a switch 2, which is communicatively connected to a controller 1, a touch screen or an industrial control computer 3, a sensor data acquisition system 6, and multiple slave stations 4. A communication interface for the centralized control system of the drilling rig is reserved on the switch 2. The slave station 4 can be expanded with I / O modules, and each slave station 4 is electrically connected to multiple electric devices 5.

[0032] The controller 1 has functions of sequence control, operation control, time control, data processing and operation, and communication. It is the nerve center of the entire control system. The switch 2 is used as a transfer for the communication information exchange between the controller 1, the touch screen or the industrial control computer 3, the sensor data acquisition system 6, the slave station 4, and the outside world. A communication interface for the centralized control system of the drilling rig is reserved on the switch 2 to facilitate the realization of process automation control. The touch screen or the industrial control computer 3 can remotely and centrally control the electric device 5 and display its operating status, realizing the synchronous action of the screen and the device. The slave station 4 can be expanded with I / O modules. On the one hand, it collects the operating status of the electric devices 5 on the tank surface for use by the controller 1, the touch screen or the industrial control computer 3, or other external control systems. On the other hand, it receives the commands issued by the controller 1 and controls the electric device 5 to act.

[0033] Communication is the bridge for information transmission in the entire control system, realizing the interaction of information among the controller 1, the touch screen or the industrial control computer 3, the slave station 4, the sensor data acquisition system 6, and the outside world. The sensor data acquisition system 6 is used to collect data from speed sensors, liquid level sensors, viscosity sensors, and density sensors. The electric device 5 is the terminal actuator, which can receive the control command of the electrical signal and at the same time feedback the operating status information to the I / O module of the slave station 4, realizing the synchronization of control and execution.

[0034] For the centralized control system of the solids control process visualization, when the user operates on the touch screen or the industrial control computer 3, the system will automatically call the corresponding control program in the controller 1. The controller 1 issues commands, and the commands are transmitted to the switch 2 through the communication line. The switch 2 issues them to the I / O module of the slave station 4 through the communication line. After receiving the commands, the slave station 4 controls the electric device 5 to act, realizing the remote centralized control of the electric device 5.

[0035] A method for visual centralized control using the centralized control system of the solids control process visualization, as Figure 2 shown, is specifically implemented according to the following steps:

[0036] Step 1: Write a control program in the controller 1 according to the drilling process. The control program includes a manual control function and multiple process control functions.

[0037] Step 2: Draw a general flow chart on the touch screen or the industrial control computer 3 according to the drilling process.

[0038] Step 3: Set a control mode selection switch on the overall flow chart of the touch screen or industrial control computer 3. The control mode selection switch is divided into a device manual control gear, a procedural manual control gear, and a procedural automatic control gear, and start / stop buttons are set next to each legend on the overall flow chart;

[0039] Step 4: Execute the corresponding process according to the control mode selected in Step 3. The control mode selection switch defaults to the device manual control gear. When changing gears, a gear confirmation prompt box will pop up. After clicking the confirmation, the function function corresponding to the gear will be called. The specific steps are as follows:

[0040] Step 4.1: When the control mode selection switch is in the device manual control gear, call the manual control function function in the controller 1. The start / stop buttons next to each legend on the overall flow chart of the touch screen or industrial control computer 3 appear. Click the start / stop buttons one by one to control the start or stop of the corresponding electric device 5. According to the start / stop position of the button and the background color of the legend, the operating status of the current electric device 5 can be known;

[0041] Step 4.2: When the control mode selection switch is in the procedural manual control gear, the start / stop buttons next to the legends on the overall flow chart of the touch screen or industrial control computer 3 will be automatically hidden, and control buttons for multiple sub-processes will appear. Each sub-process sets the sequence of starting and stopping of the electric devices 5 involved in the corresponding process according to the process. Manually select the sub-process according to the on-site drilling needs. Only when a certain sub-process control button is selected, the corresponding process function function will be called, and at the same time, a sub-process screen will pop up. The sub-process screen is provided with corresponding process start / stop buttons. Manually select the start button, and the electric devices 5 involved in the sub-process will start in the order set by the program in the controller 1. Select the stop button to stop in sequence;

[0042] Step 4.3: When the control mode selection switch is in the procedural automatic control gear, the switch 2 is communicatively connected to the drilling rig centralized control system. The start / stop buttons next to the legends on the overall flow chart are still automatically hidden, and the control buttons for the sub-processes are displayed but cannot be operated. The controller 1 sets the prerequisite conditions for calling the sub-process control function function according to the status and operating parameters of the drilling equipment such as the drawworks and mud pump provided by the drilling rig centralized control system. Only when the prerequisite conditions are met, the corresponding sub-process button will light up and automatically start the sub-process and pop up the sub-process screen.
