Description

Technical Field

[0001] The invention belongs to the field of oil and gas exploration and development, and relates to a light driller's console with an emergency linkage control function and a control method. Background Art

[0002] At present, with the continuous deepening of oil exploration and development, the exploration and development of deep and ultra-deep oil and gas resources has become the main battlefield for increasing oil and gas reserves and production in my country. Deep wells and ultra-deep wells under complex geological conditions are increasing day by day. The downhole environment faced during drilling is becoming more and more complex, and the risks and challenges are increasing dramatically. There is an urgent need for safer and more effective measures to ensure the smooth progress of drilling work and the safety of life and property of drilling workers. The blowout preventer control system is a key component of well control equipment, which plays a major safety guarantee role in controlling wellhead pressure and closing wellheads. At present, in addition to the remote control console installed under the drilling platform, the control system of the blowout preventer must also be equipped with a driller's console on the drilling platform. In an emergency, the driller can directly switch the blowout preventer on the drilling platform through the driller's console.

[0003] If the well must be shut in due to overflow during the drilling process, the driller needs to perform the well shut-in operation according to the following steps. 1 Send out an overflow alarm signal, stop drilling, and stop the pump; 2 Lift the drill bit and raise the drill pipe joint about 0.4 to 0.5 meters above the turntable surface, and instruct the inside and outside fitters to fasten the hanging card; 3 Open the four-way hydraulic flat valve and close the annular blowout preventer; 4 Close the semi-closed gate assembly that matches the drilling bit in the well, slowly place the drilling bit on the hanging card, and open the annular blowout preventer; 5 Quickly report to the duty cadre and drilling supervisor; 6 Record the shut-in vertical pressure, shut-in casing pressure and drilling fluid increment. The key operation object of step 34 is the driller's platform of the blowout preventer control device.

[0004] Traditional pneumatic driller consoles are generally large in size due to large component sizes, hard pipe connections for pipeline connections, and multiple functional requirements. To ensure practicality and reliability, their dimensions are generally large, with a volume of 0.608 to 1.111 m3, an area of ​​0.32 to 0.6 m2, a back plate area of ​​1.52 to 1.71 m2, and a weight of 150 to 300 kg. They cannot be installed in the driller's room and can only be installed on the drilling platform outside the driller's operating room. If an emergency requires emergency well shut-in, the driller cannot simultaneously complete the operation of opening and closing the blowout preventer and operating the drilling rig in the driller's room. He needs to enter and exit the driller's room many times, operate the drilling rig in the driller's room, and operate the driller's platform of the blowout preventer control system outside the driller's room to complete the above steps 345. Frequent entry and exit of the driller's room will seriously affect the rapid well shut-in time after the overflow is discovered, reduce the success rate of overflow accident disposal, and waste personnel's escape time, which may eventually lead to very serious personnel and property losses. At the same time, due to the many steps involved in shutting in the well, the driller may make an error in operating the blowout preventer control device, resulting in shut-in failure and, in turn, a well control accident.

[0005] In order to further improve the success rate of well control, prevent well control accidents, and protect the safety of personnel and property, a lightweight drilling platform that can be installed in the driller's room and has an emergency linkage control function is urgently needed. The existing well control equipment emergency shut-in linkage control device uses PLC to electrically control the ignition device, hydraulic flat valve and annular blowout preventer at the drilling site. In the event of an emergency, the ignition device, hydraulic flat valve and annular blowout preventer can be remotely controlled. In order to accommodate the electric control box, UPS and other systems, the volume of the emergency shut-in linkage control device reaches 1.013m3 and the weight reaches 300kg. It can only be installed outside the driller's room, which limits its convenience in actual use. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention is further described below with reference to the accompanying drawings. The purpose of the present invention is to innovate the structural design and component design of the driller console of the traditional gas-controlled liquid type BOP control device, so as to achieve lightweight and miniaturization of the gas-controlled liquid type driller control, and to meet the requirements of installation and direct installation in the driller's room, so that the driller can realize synchronous operation of the drilling rig and the switch of the BOP.

[0035] The present invention can, while retaining all the control functions of the driller console of the traditional blowout preventer control device, effectively reduce the size of the driller console by innovating the overall structural design, optimizing the soft connection mode of the gas pipeline, and designing and using new miniaturized gas control components, so that it can be wall-mounted in a suitable position in the driller's room; at the same time, the present invention is equipped with an emergency linkage control function, which can realize one-key operation of the well shut-in process through pneumatic automatic control logic, shorten the time required for well shut-in operation in an emergency, and buy time for the driller and operators to escape. The innovation of this invention lies in:

[0036] (1) The present invention innovatively adopts a new type of gas pipeline component, which significantly reduces the overall size of the driller's platform.

[0037] The pneumatic control connection pipelines in the driller's platform of the traditional blowout preventer control device are all hard-connected with metal pipes, and the pneumatic components and interfaces used are relatively large in size to ensure the connection strength. The present invention innovatively uses nylon flexible pressure-bearing pipes as pneumatic control connection pipelines, optimizes the interface form and the size of pneumatic components, and matches the new compact whole machine design, thus realizing the lightweight of the driller's platform.

[0038] The bare height of the lightweight driller console can be reduced to 600mm, the bare width to 500mm, and the bare thickness to 300mm. The volume of the driller's console is reduced by 90%, the back plate area is reduced by 85%, and the weight is reduced by 80%, making it easy to install in the driller's operating room;

[0039] (2) The present invention innovatively adopts a horizontal cylinder assembly structure, which significantly reduces the space occupied

[0040] The cylinder assembly used in the traditional driller console is to install the switch display board and the cylinder support rod horizontally. The switch display board and the cylinder are directly fixed to the panel by screws, and then the movement of the cylinder piston drives the support rod to realize the change of the switch display on the switch display board. The present invention innovatively adopts a horizontal cylinder assembly structure, designs the switch display board into a right angle, and stacks the switch display board and the cylinder in a three-dimensional horizontal position. The cylinder and the display board are fixed horizontally by sharing the fastening screw holes, which reduces the occupied area of ​​the rotary valve + cylinder assembly by 30% to only 0.0236m2.

[0041] (3) The present invention optimizes the operation steps of opening and closing wells, saving well control operation time

[0042] The optimized lightweight driller console of the present invention can be directly installed in the driller's room. The driller can complete the drilling rig operation and well opening and closing operation in the driller's room according to the well closing process simultaneously, without the need to frequently enter and exit the driller's room to complete the well control operation as when using the traditional driller console. This significantly reduces the time required for well control operation and buys valuable time for overflow treatment and personnel escape.

[0043] (4) The present invention innovatively designs the linkage mode between the hydraulic flat valve and the annular blowout preventer, which improves the efficiency of well control action execution

[0044] When executing step 3 "opening the four-way hydraulic flat valve and closing the annular blowout preventer", the traditional operation steps require executing two operation steps separately. The present invention redesigns the control logic and realizes the one-key linkage function. The driller only needs to press the emergency linkage control button to automatically execute all operations of the step, which reduces the complexity of the operation and improves the success rate of well control and well shut-in.

[0045] like Figure 1As shown, a light driller console with emergency linkage control includes an air pipe cable connection flange 1, an air pipe cable joint body 2, a box body 3, a pressure gauge 4, an emergency button 5, and a control handle 6. The pressure gauge, the emergency button, and various three-position four-way rotary valves in the box body are connected by air pipelines. Among the four pressure gauges 4 installed on the upper part of the box body, three display the pressure of different functional manifolds and components on the blowout preventer control device they control, and one displays the air source pressure of the light driller console with emergency linkage control. When controlling the blowout preventer control device on a daily basis, it is necessary to turn the control handle 6 to the corresponding valve position, and the air pressure can be output through the internally connected air pipe line, and the control command is sent to the blowout preventer control device after passing through the air pipe cable connection flange 1, the air pipe cable joint 2, and the air pipe cable connection square plate 15. When an emergency occurs and it is necessary to enter the well, the two emergency operation buttons 5 are pressed at the same time to start the emergency operation.

[0046] like Figure 3 As shown, an emergency control pipeline in a light driller's console with emergency linkage control includes a pressure gauge 4, an emergency operation two-position three-way pneumatic control valve 7, an all-metal air pipe four-way 8, an annular pressure regulating valve 9, a silencer type quick exhaust valve 10, a pneumatic shuttle valve 11, a two-position three-way single air-controlled reversing valve 12, a cylinder 13, a three-position four-way rotary valve 14, an air pipe cable connecting square plate connector 15, an air inlet double body 16, and an air source switch rotary valve 17.

[0047] The emergency control pipeline includes a pressure gauge 4, a bypass rotary valve, a ring rotary valve, an emergency operation two-position three-way pneumatic control valve 7, an air inlet double body 16, an all-metal air pipe four-way 8 and an air source switch rotary valve 17; the air source is connected to the air inlet double body 16, and the air inlet double body 16 is connected to the all-metal air pipe four-way 8 through a pipeline. The three outlets of the all-metal air pipe four-way 8 are respectively connected to the pressure gauge 4, the air source switch rotary valve 17, and two emergency operation two-position three-way pneumatic control valves 7 connected in series; a bypass rotary valve and a ring rotary valve are arranged in parallel between the emergency operation two-position three-way pneumatic control valve 7 and the air source switch rotary valve 17.

[0048] The bypass rotary valve includes an air inlet, a silencer type quick exhaust valve 10, a pneumatic shuttle valve 11, a two-position three-way single air-controlled reversing valve 12, a cylinder 13 and a three-position four-way rotary valve 14; the air inlet is connected to the silencer type quick exhaust valve 10 on one path, and connected to the pneumatic shuttle valve 11 on the other path; the silencer type quick exhaust valve 10, the two-position three-way single air-controlled reversing valve 12, the cylinder 13 and the three-position four-way rotary valve 14 are connected in sequence through pipelines, and the pneumatic shuttle valve 11 is connected to the three-position four-way rotary valve 14 through a pipeline.

[0049] The bypass rotary valve and the ring rotary valve have the same structure; the pipeline is a flexible material pipeline.

[0050] The three-position four-way rotary valve 14 is connected to an air pipe cable connecting square plate joint 15, and the air pipe cable connecting square plate joint 15 is connected to a main machine of a blowout preventer control device through a connecting device.

[0051] The connecting device comprises an air pipe cable connecting flange 1 and an air pipe cable joint body 2. The air pipe cable connecting flange 1 is arranged on the air pipe cable joint body 2. The air pipe cable joint body 2 is connected to the air pipe cable connecting square plate joint 15. The air pipe cable connecting flange 1 is connected to the main unit of the blowout preventer control device.

[0052] An annular pressure regulating valve 9 is arranged between the all-metal air pipe cross-connection 8 and the emergency operation two-position three-way pneumatic control valve 7.

[0053] The box body 3 is also provided with three pressure gauges 4 for displaying the pressures of different function manifolds and components on the main unit of the blowout preventer control device.

[0054] Two emergency buttons 5 and a control handle 6 are arranged on the box body 3 . The two emergency buttons 5 correspond to and control the emergency operation of the two-position three-way pneumatic control valve 7 , respectively. The control handle 6 is used to control the three-position four-way rotary valve 14 .

[0055] When emergency operation needs to be initiated, first ensure that the air source switch is in the open state. At this time, the air can be filtered and dried through the air inlet double body 16 and then delivered to the operating system. The pressure of the annular blowout preventer manifold is adjusted to about 10.5MPa through the annular pressure regulating valve 9 to ensure that the annular blowout preventer is closed normally. After that, by simultaneously triggering the two emergency operation two-position three-way starting control valves 7, the compressed air can enter the action system cylinder 13 through the silencer type quick exhaust valve 10, the pneumatic shuttle valve 11 and the two-position three-way single air-controlled reversing valve 12. The valve block in the cylinder 13 is pushed by the compressed air to drive the rotation of the three-position four-way rotary valve 14. The compressed air in the pipeline transmits the opening and closing information represented by the rotation of the three-position four-way rotary valve 14 to the blowout preventer control device through the air pipe cable connecting square plate 15 joint, completing the emergency control of the blowout rotary valve and the annular rotary valve on the blowout preventer control device, and realizing the functions of closing the annular blowout preventer and opening the blowout valve.

[0056] Example:

[0057] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0058] A light driller's console with emergency linkage control has the following dimensions: bare machine height 600mm, bare machine width 500mm, bare machine thickness 300mm, and its main body is composed of an air pipe cable connecting flange 1, an air pipe cable joint body 2, a box body 3, a pressure gauge 4, an emergency button 5, and a control handle 6; the control pipeline inside the box body is composed of a pressure gauge 4, an emergency operation two-position three-way pneumatic control valve 7, an all-metal plug air pipe four-way 8, an annular pressure regulating valve 9, a silencer type quick exhaust valve 10, a pneumatic shuttle valve 11, a two-position three-way single air-controlled reversing valve 12, a cylinder 13, a three-position four-way rotary valve 14, an air pipe cable connecting square plate 15, an air inlet double body 16, and an air source switch rotary valve 17.

[0059] In standby mode, the air source is connected to the light driller console through the air inlet doublet 16, and the air source is introduced into the pressure gauge 4 and the control pipeline through the all-metal gas pipe spool 8. By opening the air source switch valve 17, air is supplied to the three-position four-way rotary valve 14. In this way, when the three-position four-way rotary valve 14 is controlled on the light driller console, the corresponding rotary valve on the main machine of the blowout preventer control device can be controlled by air pressure. In standby mode, the annular pressure regulating valve 9 can be used to adjust the output pressure of the annular blowout preventer control rotary valve.

[0060] When an overflow accident occurs and the well needs to be shut down urgently, the driller can choose pneumatic emergency operation or manual operation for viewing. When the emergency operation is started, the driller needs to press two emergency buttons 5 at the same time. At this time, the emergency operation two-position three-way pneumatic control valve 7 is connected, and the air passes through the silencer type quick exhaust valve 10 and the pneumatic shuttle valve 11. At this time, the two-position three-way single air-controlled reversing valve 12 is opened under the air pressure at the emergency button end, and the air enters the cylinder 13 of the bypass rotary valve and the annular rotary valve respectively, pushing the cylinder piston to move, and the three-position four-way rotary valve 14 of the annular blowout preventer control valve is pushed to the "off" position, and the three-position four-way rotary valve 14 of the bypass valve control valve is pushed to the "open" position. The pneumatic control signal is transmitted to the main engine of the blowout preventer control device through the air pipe cable connecting square plate 15, the air pipe cable connecting flange 1 and the air pipe cable joint body 2. At this time, the bypass rotary valve on the main engine and the light driller console is turned to the "on" position, and the annular blowout preventer control rotary valve is turned to the "off" position. The bypass valve is controlled to open and the annular blowout preventer is controlled to close. Finally, manually pull the control handle 6 of the semi-closed gate control valve to turn the three-position four-way rotary valve 14 to the "closed" position to achieve controlled closure of the semi-closed gate blowout preventer. At the same time, control the brake handle in the driller's room to slowly place the drill tool on the elevator, and then turn the control handle 6 of the annular blowout preventer control valve in the driller's room to turn the three-position four-way rotary valve 14 to the "open" position to open the annular blowout preventer, thus completing the well shut-in operation.

[0061] When performing emergency operation manually, the driller manually turns the control handle 6 of the bypass valve in the driller's room to turn the three-position four-way rotary valve 14 to the "open" position, and then manually turns the control handle 6 of the annular blowout preventer control rotary valve to turn the three-position four-way rotary valve 14 to the "closed" position. At this time, the cylinders 13 of the bypass valve and the annular blowout preventer control rotary valve are also pushed to the "open" or "closed" position respectively. The air control signal is transmitted to the main unit of the blowout preventer control device through the air pipe cable connecting square plate 15, the air pipe cable connecting flange 1 and the air pipe cable joint body 2. At this time, the bypass rotary valve on the main unit of the blowout preventer control device will be turned to the "open" position, and the annular blowout preventer control rotary valve will be turned to the "closed" position, the bypass valve is controlled to open, and the annular blowout preventer is controlled to close. Finally, manually pull the control handle 6 of the semi-closed gate control valve to turn the three-position four-way rotary valve 14 to the "closed" position to achieve controlled closure of the semi-closed gate blowout preventer. At the same time, control the brake handle in the driller's room to slowly place the drill tool on the elevator, and then turn the control handle 6 of the annular blowout preventer control valve in the driller's room to turn the three-position four-way rotary valve 14 to the "open" position to open the annular blowout preventer, thus completing the well shut-in operation.

[0062] A light driller's console with an emergency linkage control function, the structure of which mainly includes air pipelines, pneumatic components, a shell, a pneumatic control system, etc.

[0063] The air pipeline of a light driller's console with an emergency linkage control function is made of flexible materials. The air pipeline on the driller's console of a traditional blowout preventer control device is made of metal pipes such as copper pipes or stainless steel pipes. Due to the limited plasticity of the metal air pipeline, a large space is required to realize the bending connection between the pneumatic components and the air source in the driller's console shell, which leads to a large weight of the driller's console. Unlike the driller's console of a traditional blowout preventer control device, the air pipeline in the light driller's console uses a flexible nylon hose pipeline to connect the air source and various pneumatic components. The use of nylon hose can significantly reduce the space occupied by the pipeline when it is bent, effectively reducing the box size required for pipe laying; at the same time, it is light in weight, which helps to reduce the weight of the whole machine.

Among them, the newly designed light double-acting cylinder achieves the miniaturization of the rotary valve + cylinder set by optimizing the configuration of the cylinder assembly, reducing the occupied area from 0.0336m2 to 0.0236m2, significantly reducing the space occupied by pneumatic components, and at the same time providing a basis for the miniaturization design of the driller's console shell.

[0065] The shell of a light driller console with emergency linkage control function is made of metal materials such as stainless steel. Due to the miniaturization of pneumatic components and the flexible design of air pipelines, the shell size of the light driller console is effectively reduced, with a shell height of 600mm, a bare machine width of 500mm, and a bare machine thickness of 300mm. The volume of the driller console is reduced by 90%, the back plate area is reduced by 85%, and the weight is reduced by 80%, making it easy to move and install.

[0066] A blowout preventer control device driller console, the pneumatic control control system adopts the control form of master station and slave station, the driller console slave station remotely controls the remote console master station, and air pipe cables are used to transmit signals between the master station and the slave station.
