Detailed Description
Example 1:
as shown in fig. 1, a gas field multi-port multi-pressure gathering and conveying system comprises a driving turbine 1 and a driven turbine 2, wherein a transmission mechanism is arranged between the driving turbine 1 and the driven turbine 2; the preferred drive mechanism employs a drive shaft, such as a drive shaft connected by a coupling; or the transmission mechanism is a constant-proportion speed-increasing transmission mechanism or a stepless variable-proportion speed-increasing transmission mechanism, such as a straight gear speed-increasing gearbox, or a speed-changing speed-increasing gearbox, such as a double clutch or CVT speed-changing gearbox, namely, the output rotating speed of the driving turbine 1 is increased, and then the output rotating speed of the driving turbine is output to the driven turbine 2, so that the rotating speed of the driven turbine 2 is higher than the rotating speed of the driving turbine 1. Preferably, the rotation speed of the driven turbine 2 is 1.5-3 times that of the driven turbine 2.
The driving turbine 1 is used for being arranged on a pipeline of the high-pressure gas source 7 so that the high-pressure gas pushes the driving turbine 1 and the driven turbine 2 to rotate; the driven turbine 2 is arranged in the line of the low-pressure gas source 8 for pressurizing the latter. The driving turbine 1 and the driven turbine 2 are designed to be corrosion resistant, preferably aluminum coated blades, and the coating is a polytetrafluoroethylene coating.
In a preferred embodiment, a non-return valve 6 is provided at the outlet of the driven turbine 2. With this construction, the high pressure gas is prevented from returning to the line of the low pressure gas source 8.
The principle of the scheme is that the rotation speed between the driving turbine 1 and the driven turbine 2 is self-adaptive, when the pressure difference between the high-pressure air source 7 and the low-pressure air source 8 is high, the consumed pressure at the driving turbine 1 is also high, the rotation speed of the driven turbine 2 is increased, the supercharging effect of the low-pressure air source 8 is better, and accordingly the pressure at the outlet 10 of the total air source is consistent. And when the pressure difference between the high-pressure air source 7 and the low-pressure air source 8 is low, the consumed pressure at the active turbine 1 is low, and the supercharging effect of the low-pressure air source 8 is not obvious.
Example 2:
on the basis of the embodiment 1, a medium-pressure air source 9 is further arranged, the medium-pressure air source 9 is directly connected with a total air source outlet 10, and a one-way valve 6 is arranged on a pipeline of the medium-pressure air source 9. With this structure, when the output pressure of the air source is consistent with the pressure of the total air source outlet 10, the air source does not need to pass through the driving turbine 1 or the driven turbine 2, thereby reducing the energy consumption.
Example 3:
on the basis of the embodiment 1 or 2, as shown in fig. 1, the number of the driven turbines 2 is more than one, and the driven turbines 2 are connected through a transmission mechanism to transmit torque;
each driven turbine 2 is provided separately in the line of each low pressure gas source 8. With this configuration, the plurality of low-pressure air sources 8 can be pressurized, and the overall output pressure can be adjusted.
Example 4:
in the preferred embodiment, as shown in fig. 2, a clutch 12 is provided on the transmission mechanism between the driven turbines 2;
a clutch 12 is arranged on the transmission mechanism between the driving turbine 1 and the driven turbine 2. With this configuration, it is possible to switch whether to start the driving turbine 1 or the driven turbine 2 or to start only part of the driven turbine 2, depending on the operating conditions. When the driving turbine 1 or the driven turbine 2 is not started, the high-pressure electric control valve 4 or the electric control valve 5 on the current pipeline is closed. To further reduce the energy consumption.
In a preferred embodiment, as shown in fig. 2, bypass lines 11 are provided at both ends of the active turbine 1. With this structure, when neither the driving turbine 1 nor the driven turbine 2 is started, the high-pressure air source 7 can be directly led to the bypass line 11, thereby reducing the pressure loss.
Example 5:
as shown in fig. 3, the preferred scheme is also provided with a high-voltage auxiliary motor 13, and the high-voltage auxiliary motor 13 is connected with the active turbine 1 through a high-voltage clutch 14;
a first pressure sensor 18 is provided at the outlet of the active turbine 1.
In a preferred scheme, a low-pressure auxiliary motor 17 is also arranged, and the low-pressure auxiliary motor 17 is connected with the driven turbine 2 through a low-pressure clutch 16 and a one-way coupling 15;
a second pressure sensor 19 is provided at the outlet of the driven turbine 2. With this structure, the output pressure of the total gas source outlet 10 is finely adjusted, so that the situation that the loss of partial wellhead output pressure is too high is avoided. In particular, the output pressure fluctuations of the wellhead can be equalized.
Example 6:
as shown in fig. 1 to 3, a method for adopting the gas field multi-port multi-pressure gathering and transporting system comprises the following steps:
s1, arranging an active turbine 1 on a pipeline of a high-pressure air source 7, namely connecting an inlet and an outlet of the active turbine 1 with the pipeline of the high-pressure air source 7 respectively, disconnecting the pipeline of the high-pressure air source 7 by using a ball valve, and pushing the active turbine 1 to rotate by using the high-pressure air source, wherein an air source after consuming a certain pressure is discharged to a total air source outlet 10;
a driven turbine 2 is arranged on a pipeline of the low-pressure air source 8, namely, an inlet of the driven turbine 2 is directly connected with the pipeline of the low-pressure air source 8, and the driven turbine 2 is utilized to pressurize the low-pressure air source and then is discharged to a total air source outlet 10;
the driving turbine 1 is connected with the driven turbine 2 through a transmission mechanism, so that the driving turbine 1 drives the driven turbine 2 to rotate;
s2, connecting the outlet of the driving turbine 1 and the outlet of the driven turbine 2 to a total air source outlet 10;
through the steps, the multi-port and multi-pressure centralized input of the gas field to the compressor is realized.
The preferred embodiment is as shown in fig. 3, and further comprises the following steps:
the total air source outlet 10 is also connected with a medium pressure air source 9, and a third pressure sensor 20 is arranged on a pipeline of the medium pressure air source 9;
a first pressure sensor 18 is arranged at the outlet of the driving turbine 1, and a second pressure sensor 19 is arranged at the outlet of the driven turbine 2;
the high-voltage auxiliary motor 13 is also arranged, and the high-voltage auxiliary motor 13 is connected with the driving turbine 1 through a high-voltage clutch 14;
the low-voltage auxiliary motor 17 is also arranged, and the low-voltage auxiliary motor 17 is connected with the driven turbine 2 through the low-voltage clutch 16 and the one-way coupling 15; the unidirectional coupling 15 is a coupling that can be driven only in one direction, that is, when the low-pressure auxiliary motor 17 transmits torque in one direction, the driven turbine 2 can be driven to rotate to boost the pressure of the low-pressure air source 8, and when the speed of the driven turbine 2 is higher due to the air pressure from the low-pressure air source 8, the unidirectional coupling 15 does not reversely transmit torque.
The specific fine tuning control steps are as follows:
s01, if the value of the first pressure sensor 18 is lower than that of the third pressure sensor 20, starting the high-pressure auxiliary motor 13, and increasing the pressure at the outlet of the active turbine 1 on the high-pressure air source 7 to be consistent with the pipeline pressure of the medium-pressure air source 9;
s02, if the value of the second pressure sensor 19 is lower than that of the third pressure sensor 20, starting the low-pressure auxiliary motor 17 to increase the pressure at the outlet of the driven turbine 2 on the low-pressure air source 8 to be consistent with the pipeline pressure of the medium-pressure air source 9;
s03, if the value of the third pressure sensor 20 of the medium pressure air source 9 is lower than that of the first pressure sensor 18 or the second pressure sensor 19, the medium pressure air source 9 is switched into the driven turbine 2, and then S1 and S2 are executed.
The pressure equalization output to the total gas source outlet 10 is achieved through the above steps.
In a further preferred solution, the high-voltage auxiliary motor 13 and the low-voltage auxiliary motor 17 adopt a constant torque output control mode, that is, the output torque is a constant value, when the required input torques of the driving turbine 1 and the driven turbine 2 are smaller, that is, the matching degree between the high-pressure air source 7 and the low-pressure air source 8 and the driving turbine 1 and the driven turbine 2 is higher, the two can make the output pressures more balanced, and then the output torques of the high-voltage auxiliary motor 13 and the low-voltage auxiliary motor 17 make the driving turbine 1 and the driven turbine 2 form new balance. When the matching degree between the high-pressure air source 7 and the low-pressure air source 8 and the driving turbine 1 and the driven turbine 2 is low, the output torque of the high-pressure auxiliary motor 13 and the low-pressure auxiliary motor 17 balances the rotation speeds of the driving turbine 1 and the driven turbine 2, so that the pressure loss of each air source is reduced.
In another alternative scheme, the speed regulation control mode is adopted by the high-pressure auxiliary motor 13 and the low-pressure auxiliary motor 17, a matrix data corresponding table of the rotation speeds of the driving turbine 1 and the driven turbine 2 and the input pressure and the output pressure is firstly established, then according to the acquisition parameters of the first pressure sensor 18, the second pressure sensor 19 and the third pressure sensor 20, the third pressure sensor 20 of the medium-pressure air source 9 is used as a control input parameter, then the target rotation speeds of the driving turbine 1 and the driven turbine 2 corresponding to the first pressure sensor 18 and the second pressure sensor 19 are respectively obtained, and then the rotation speed difference between the current rotation speeds and the target rotation speeds obtained according to the matrix data corresponding table is calculated, so that the whole system operates in an optimized energy-saving mode according to the scheme.
