[0025] In order to make objectives, technical details, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the present disclosure. Apparently, the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the present disclosure.

[0027] A fracturing operation has two basic requirements on fracturing equipment. Firstly, there can be no displacement output at an engine warm-up stage, and a fracturing pump can be started to provide displacement only when necessary. Secondly, in case of an emergency situation that includes an overpressure situation, the output needs to be cut off urgently, that is, the fracturing pump needs to be separated from a front end to avoid accidents.
[0028] Some existing fracturing equipment is provided with a clutch. However,
because the clutch cannot be engaged at a high speed, the clutch can be engaged only
before starting, and otherwise, the clutch may be damaged. Therefore, the clutch is
engaged before starting, and a turbine engine is started when the displacement is
needed; and in case of emergency, the clutch is separated, and the fracturing pump
is stopped under an inertia effect or a load of a wellhead.
[0029] However, some problems occur in the case where a turbine fracturing
device adopts the clutch to implement the quick separation. Firstly, the clutch must
be engaged before the starting of the equipment, which restricts an application
range of the clutch. The clutch can be engaged only before the starting. If the clutch
is engaged again after the overpressure, it is necessary to stop the equipment, thus
the quick starting of the equipment cannot be realized. Secondly, after the
overpressure protection, the clutch separates the fracturing pump quickly from a
speed reducer, and the instantaneous loss of load leads to possible runaway of the
turbine engine, which brings risks to the turbine engine. Of course, in the case where
the fracturing pump is stopped under the inertia effect or the load of the wellhead,
which still has certain impact on the rear end. Moreover, the clutch is not suitable
for being started and stopped frequently, which easily causes the damage to seals,
shortens the service life, and increases the maintenance cost.
[0030] FIG. 1 is a schematic diagram of a turbine fracturing device provided by
an embodiment of the present disclosure. As illustrated in FIG. 1, the turbine
fracturing device includes a turbine engine 1, a speed reducer 2, a torque limiter 3, a
transmission mechanism 4, and a fracturing pump 5. As illustrated in FIG. 1, the
turbine engine 1, the speed reducer 2, the torque limiter 3, the transmission
mechanism 4, and the fracturing pump 5 are connected in sequence to form a
transmission system of the turbine fracturing device. For example, the transmission
mechanism 4 includes a coupling. For example, the fracturing pump 5 includes a piston pump. For example, the fracturing pump 5 is configured to suck low-pressure fracturing fluid and pressurize the low-pressure fracturing fluid to form high-pressure fracturing fluid. The pressure of the high-pressure fracturing fluid is greater than the pressure of the low-pressure fracturing fluid. The low-pressure fracturing fluid may also be referred to as suction fluid. The high-pressure fracturing fluid may also be referred to as discharge fluid. The low-pressure fracturing fluid may also be referred to as fluid of first pressure. The high-pressure fracturing fluid may also be referred to as fluid of second pressure. For example, the fracturing pump is configured to suck the fluid of the first pressure and discharge the fluid of the second pressure. The second pressure is greater than the first pressure. For example, the turbine fracturing device provided by some embodiments of the present disclosure may also not be provided with the torque limiter 3. In this case, the speed reducer 2 is connected with the fracturing pump 5 through the transmission mechanism 4.
[0031] As illustrated in FIG. 1, a brake mechanism 6 may be arranged
between the speed reducer 2 and the fracturing pump 5 to keep the speed reducer 2
and the fracturing pump 5 in a disconnected state. According to the turbine
fracturing device provided by the embodiments of the present disclosure, the brake
mechanism 6 is provided to make the speed reducer 2 disconnected from the
fracturing pump 5. The speed reducer 2 and the fracturing pump 5 may be in a
disconnected or a connected state. In the embodiments of the present disclosure,
when the speed reducer 2 and the fracturing pump 5 are in the disconnected state,
the fracturing pump 5 is in a non-operating state, when the speed reducer 2 and the
fracturing pump 5 are in the connected state, the fracturing pump 5 is in an
operating state.
[0032] FIG. 2 is a perspective schematic view of a brake mechanism of a
turbine fracturing device provided by an embodiment of the present disclosure. FIG.
3 is a side view of a brake mechanism of a turbine fracturing device provided by an embodiment of the present disclosure. As illustrated in FIG. 2 and FIG. 3, the brake mechanism 6 includes a brake plate 61 and a brake block 62. For example, the friction between the brake plate 61 and the brake block 62 plays a brake role. For example, the brake block 62 may also be referred to as a friction block. For example, in a brake state, the brake mechanism 6 is used as a load of an output shaft of the turbine engine to bear the power output of the output shaft of the turbine engine, so that the fracturing pump 5 is in the non-operating state. FIG. 1 to FIG. 3 are illustrated with reference to the case where the brake mechanism 6 is located at a side of speed reducer 2 opposite to a side of the speed reducer 2 that is connected with the turbine engine 1, by way of example, but the embodiments of the present disclosure are not limited thereto. In other embodiments, the brake mechanism 6 may also be arranged at other suitable positions. For example, the brake mechanism 6 may be arranged between the transmission mechanism 4 and the fracturing pump , i.e. arranged on an input shaft of the fracturing pump 5.
[0033] The embodiments of the present disclosure take the turbine fracturing device illustrated in FIG. 1 to FIG. 3 as an example for description, but are not limited thereto. The structure of the turbine fracturing device may be determined according to the requirements.
[0034] FIG. 4 is a schematic diagram of an operation method of the turbine fracturing device provided by an embodiment of the present disclosure. As illustrated in FIG. 4, the entire operation of the turbine fracturing device is carried out according to an idling instruction. The idling instruction controls the brake operation directly.
[0035] At least one embodiment of the present disclosure provides an operation method of a turbine fracturing device. Referring to FIG. 1 to FIG. 4, the turbine fracturing device includes a turbine engine 1, a speed reducer 2, a brake mechanism 6, and a fracturing pump 5. The operation method of the turbine fracturing device includes: driving, by the turbine engine 1, the fracturing pump 5 to perform a fracturing operation through the speed reducer 2 so as to keep the fracturing pump 5 in an operating state; and in response to an idling instruction, the turbine engine 1 entering an idling state, and triggering a brake operation to keep the fracturing pump 5 in a non-operating state. For example, when the turbine engine 1 is in the idling state, the output power of the turbine engine 1 is very small.
[0036] For example, in other embodiments, the operation method of the turbine fracturing device includes: in response to the idling instruction, the turbine engine 1 entering the idling state; and the idling instruction triggering a brake instruction, and in response to the brake instruction, triggering the brake operation to keep the fracturing pump 5 in the non-operating state. Responding to the brake instruction or performing the brake operation, the turbine fracturing device enters a brake state. For example, the brake operation is to control a rotation speed of an output shaft of a reduction gearbox. For example, the brake instruction is triggered at the same time when the turbine engine 1 is in the idling state. For example, the brake instruction is triggered at the same time when the idling instruction is issued.
[0037] The fracturing pump 5 is in the operating state, which refers to that the fracturing pump 5 sucks low-pressure fluid and discharges high-pressure fluid. The fracturing pump 5 is in the non-operating state, which refers to that the fracturing pump 5 does not suck the low-pressure fluid and does not discharge the high-pressure fluid. For example, the fracturing pump 5 is in the operating state, which may refer to that the fracturing pump 5 has displacement output. The fracturing pump 5 is in the non-operating state, which refers to that the fracturing pump 5 has no displacement output.
[0038] For example, referring to FIG. 1, an output shaft of the turbine engine 1 is connected with an input shaft of the speed reducer 2. An output shaft of the speed reducer 2 is connected with the input shaft of the fracturing pump 5.
[0039] For example, the idling state refers to the state of the turbine engine 1. In response to the idling instruction, the turbine fracturing device adjusts the rotation speed of the output shaft of the turbine engine 1. For example, in the case where the turbine engine 1 is driven by fuel oil, the rotation speed of the output shaft of the turbine engine 1 may be adjusted by adjusting an oil intake quantity. For example, the rotation speed of the output shaft of the turbine engine 1 may be reduced by reducing the oil intake quantity. For example, in the case where the turbine engine 1 is driven by gas, the rotation speed of the output shaft of the turbine engine 1 may be adjusted by adjusting the gas intake quantity. For example, the rotation speed of the output shaft of the turbine engine 1 may be reduced by reducing the gas intake quantity.
[0040] For example, in the idling state, the rotation speed of the output shaft of the turbine engine 1 is less than the rotation speed of the turbine engine 1 when driving the fracturing pump 5 to perform the fracturing operation. For example, in the idling state, the rotation speed of the output shaft of the turbine engine 1 is stable and greater than a set value, for example, the set value is 0, that is, in the idling state, the rotation speed of the output shaft of the turbine engine 1 is greater than 0. For example, in the idling state, the rotation speed of the output shaft of the turbine engine 1 is relatively small. For example, in a brake state, the rotation speed of the output shaft of the turbine engine 1 is 0. For example, in the case where the turbine fracturing device is in the operating state, the rotation speed of the output shaft of the turbine engine 1 is greater than the rotation speed of the input shaft of the fracturing pump 5.
[0041] For example, as illustrated in FIG. 4, the operation method of the turbine fracturing device further includes: triggering an overpressure instruction in the case where the pressure of the fluid of the second pressure discharged by the fracturing pump 5 is greater than an overpressure protection value, and the overpressure instruction triggering the idling instruction. In response to the overpressure instruction, the turbine fracturing device enters an overpressure protection state.
[0042] For example, the overpressure instruction is sourced from a pressure
sensor of the fracturing pump. The pressure sensor is configured to detect a pressure
of the high-pressure fracturing fluid of the fracturing pump. When the pressure
sensor detects that the pressure of the high-pressure fracturing fluid is greater than
the predetermined overpressure protection value, the overpressure instruction is
triggered directly, and the idling state is further triggered.
[0043] For example, as illustrated in FIG. 4, the operation method of the
turbine fracturing device further includes: starting the turbine engine 1 in response
to a start instruction before the fracturing pump 5 is in the operating state; and the
start instruction triggering the idling instruction, so that the turbine engine 1 is in
the idling state during a start process of the turbine engine 1.
[0044] For example, during the start process of the turbine engine 1, the start
instruction is controlled manually; in response to the start instruction, the turbine
fracturing device executes a start process; and during the entire start process, the
turbine fracturing device is always in the idling state.
[0045] For example, as illustrated in FIG. 4, the operation method of the
turbine fracturing device further includes: terminating the operating state of the
fracturing pump 5 in response to an operation termination instruction when the
fracturing pump 5 is in the operating state, and the operation termination
instruction triggering the idling instruction.
[0046] For example, as illustrated in FIG. 4, the operation termination
instruction is inputted manually to terminate the operating state of the fracturing
pump 5.
[0047] For example, as illustrated in FIG. 4, the operation termination instruction is triggered by an alarm protection program to terminate the operating state of the fracturing pump 5; and the alarm protection program includes triggering the operation termination instruction in at least one of cases where the pressure of the lubricating oil of the fracturing pump 5 is less than a first predetermined value, the temperature of the lubricating oil of the fracturing pump 5 is greater than a second predetermined value, or the pressure of the lubricating oil of the speed reducer 2 is less than a third predetermined value. For example, the alarm protection program is a preset program.
[0048] For example, when the fracturing pump 5 is in the operating state, the operation termination instruction may be triggered under two conditions: one is that the operation termination instruction is inputted manually according to the operation displacement requirement to terminate the operating state of the fracturing pump 5, so that the turbine engine 1 enters the idling state. The other one is to trigger the operation termination instruction according to the preset alarm protection program. For example, the operation termination instruction may be triggered by the conditions such as the low pressure of the lubricating oil of the fracturing pump, the high temperature of the lubricating oil of the fracturing pump, and the low pressure of the lubricating oil of the reduction gearbox.
[0049] For example, as illustrated in FIG. 4, the operation method of the turbine fracturing device further includes: stopping the operation of the fracturing pump in response to an emergency stop instruction; the emergency stop instruction triggering the idling instruction; and triggering the emergency stop instruction includes at least one of triggering the emergency stop instruction by an emergency stop protection program or manually judging emergencies to trigger the emergency stop instruction on the premise that the emergency stop protection program is not triggered. The emergency stop protection program includes triggering the emergency stop instruction in at least one of cases where the pressure of the lubricating oil of the turbine engine 1 is less than a fourth predetermined value, a vibration amplitude of the turbine engine 1 is greater than a fifth predetermined value, or the exhaust temperature of the turbine engine 1 is greater than a sixth predetermined value. For example, the emergency stop protection program is a preset program.
[0050] For example, the emergency stop instructions are from two ways. One
is to manually judge the emergencies to trigger the emergency stop instruction on
the premise that the emergency stop protection program is not triggered, and further
trigger the idling state; and the other one is to trigger the preset emergency stop
protection program to keep the turbine fracturing device in an emergency stop state;
and for example, the emergency stop instruction is triggered in at least one of cases
where the pressure of the lubricating oil of the turbine engine is excessively low, the
vibration amplitude of the turbine engine is excessively high, or the exhaust
temperature of the turbine engine is excessively high, and the idling state is further
triggered.
[0051] For example, the operation method of the turbine fracturing device
further includes: stopping the operation in response to the stop instruction so that
the turbine fracturing device is stopped, the stop instruction triggering the idling
instruction.
[0052] When the operation is ended and the stop is needed, the stop
instruction is inputted manually, the stop instruction triggers the idling instruction,
and the turbine engine 1 enters the idling state; and the idling instruction triggers
the brake operation, so that the turbine fracturing device is stopped.
[0053] As illustrated in FIG. 4, at least one of the overpressure instruction, the start instruction, the operation termination instruction, the stop instruction and the emergency stop instruction may trigger the idling instruction, and further trigger the brake operation.
[0054] The brake operation is triggered by the above idling instruction or brake instruction so as to realize the brake operation of the turbine fracturing device. For example, in some embodiments, the idling instruction triggers the brake operation directly.
[0055] According to the operation method of the turbine fracturing device provided by the embodiments of the present disclosure, the idling instruction makes the turbine engine enter the idling state and triggers the brake operation, which is beneficial to the quick use and response of the turbine fracturing device and beneficial to the quick re-operation of the turbine fracturing device, thereby improving the operation reliability of the turbine engine and the reliability of a fracturing well site. The turbine fracturing device provided by the embodiments of the present disclosure has no clutch, and adopts the brake mechanism to perform the brake operation when the turbine engine is in the idling state.
[0056] Compared with the turbine fracturing device provided with a clutch, the turbine fracturing device provided with the brake mechanism has at least one of the following advantages.
[0057] (1) The clutch is complicated in structure, and it is troublesome to replace spare parts, especially vulnerable parts such as oil seals. The brake mechanism is simple in structure and convenient to install, and it is convenient to replace the brake plate of the brake mechanism.
[0058] (2) The clutch needs to be engaged and connected only at a low speed. If the clutch is disconnected, the clutch can be reconnected only after the speed of the turbine fracturing device is reduced; therefore, there are restrictions on the operation of the turbine fracturing device. While the engagement and disconnection of the brake mechanism have no requirement on the rotation speed.
[0059] (3) In the working state, the clutch must be in a connected state, and if
the clutch is in failure, the field operation cannot be continued. However, in the
working state, the brake operation is in the disconnected state, and if the brake
mechanism is in failure, the normal operation of the turbine fracturing device is not
affected.
[0060] (4) The brake operation is started in the start process. The start process
may be judged automatically without determining the state of the turbine fracturing
device, such as the engagement and separation judgment.
[0061] (5) The turbine fracturing device provided with the brake mechanism
may determine whether to enter the idling state or the operating state as required.
The turbine fracturing device may be started in advance, and may also be put into
use at any time by switching the operating state and the idling state at any time.
The turbine fracturing device provided with the clutch has an excessively long start
process, which affects the quick use and response of the turbine fracturing device.
[0062] (6) It is only necessary to trigger the idling instruction and the brake
operation after the overpressure, and it is unnecessary to trigger the stop instruction,
so that the turbine fracturing device may be re-operated quickly.
[0063] (7) The brake operation needs to consume power, which may make the
turbine fracturing device stopped under the load instead of transmitting the power
to the rear end, so that the operation risk of the turbine engine and the risk of the
well site may be reduced, and the operation reliability of the turbine engine and the
reliability of the fracturing well site can be improved.
[0064] For example, in some embodiments of the present disclosure, the first
predetermined value, the second predetermined value, the third predetermined
value, the fourth predetermined value, the fifth predetermined value, and the sixth predetermined value may be set according to requirements.

engine 1 is in an idling state, the brake block 62 contacts the brake plate 61 to
perform the brake operation so as to control a rotation speed of the transmission
shaft 70 of the reduction gearbox 2, so that the rotation speed of the transmission
shaft 70 is reduced, for example, the brake operation may make the rotation speed of
the transmission shaft 70 become 0.
