Description
Technical field
The utility model is related to well workover perfusion field, especially one kind being related to well workover perfusion system.
Background technology
The most important thing of the well control as underground work, and play the probability maximum that blowout occurs for lower tubular column operation.Due to tubing string
Rise or leakage, pumping phenomenon etc., fail that workover fluid is replenished in time in the construction process, lead to the liquid level meeting in casing
Decline, causes strata pressure to be more than pit shaft head of liquid, well control risk often occur.In order to ensure construction safety is effective, all it is
Workover fluid is perfused by manual control and measures, calculate the amount of pouring into, liquid filling is frequently and each amount of pouring into is little, needs special messenger's control
It is used in combination ruler to go to measure big jar liquid surface.But since the amount of pouring into is little, the variation also little and ullage meeting sometimes of liquid level generation
There is oily foam, so the precision of metering is not high.It not only needs special messenger seat hilllock but also cost payout increases.
For this purpose, in order to solve the measurement problem of perfusion workover fluid, a kind of well workover perfusion metering system is designed, more than solution
Problem.

Bottom portion is connected with outlet tube；
The liquid filling amount control system includes the first electrically operated valve being arranged on liquid-in pipe, be arranged on outlet tube
Two electrically operated valves are arranged in the liquid level sensor and controller determined on volume liquid case inner roof wall；
The liquid level sensor is wirelessly connected to controller, the controller be wirelessly connected to respectively the first electrically operated valve and
Second electrically operated valve；The controller is connected with display；
The controller can control the keying of the first electrically operated valve and the second electrically operated valve, the liquid level sensor that can monitor
To liquid level signal, liquid level signal is sent to controller, the controller sends liquid level signal to display, and display can be shown
Liquid level signal each time is shown.
Further, the controller is PLC controller.
Preferably, the controller is wirelessly connected with mobile terminal.
Particularly, the controller is connected with alarm.
The utility model has the beneficial effects that：
One kind described in the utility model is related to well workover perfusion system, easy to use, can accurately measure repairing for addition
Well liquid total amount avoids and artificially goes to measure the amount of pouring into, avoids and cause danger into well, remote controlled addition, and the speed added
Degree is controllable.

Specific implementation mode
It is described in detail with reference to attached drawing below with reference to the embodiments of the present invention.
A kind of well workover perfusion metering system, including well workover perfusion component and liquid filling amount control system；
As shown in Figure 1, the well workover perfusion component includes liquid-in pipe 1, the liquid-in pipe 1, which is connected with, determines volume liquid case 4,
It is described to determine 4 bottom of volume liquid case and be connected with outlet tube 6；
As depicted in figs. 1 and 2, the liquid filling amount control system include the first electrically operated valve 2 being arranged on liquid-in pipe 1,
The second electrically operated valve 5 for being arranged on outlet tube 6 is arranged in the liquid level sensor 3 determined on 4 inner roof wall of volume liquid case and control
Device processed；
As shown in Fig. 2, the liquid level sensor 3 is wirelessly connected to controller, the controller is wirelessly connected to respectively
One electrically operated valve 2 and the second electrically operated valve 5；The controller is connected with display；
The controller can control the keying of the first electrically operated valve 2 and the second electrically operated valve 5, and the liquid level sensor 3 can
Liquid level signal is monitored, sends liquid level signal to controller, the controller sends liquid level signal to display, display
It can show liquid level signal each time.
Further, the controller is PLC controller.
Preferably, the controller is wirelessly connected with mobile terminal.
Particularly, the controller is connected with alarm.
Principle and application method：
Liquid-in pipe 1 connects workover fluid storage bin, and when needing to add workover fluid, controller controls the first electrically operated valve 2 and opens,
Second electrically operated valve 5 is closed, the workover fluid determines volume liquid case 4 from liquid-in pipe 1 into described；
When the workover fluid determined in volume liquid case 4 touches the liquid level sensor 3, the liquid level sensor 3 is sent out
The number of delivering letters arrives controller, and the controller shows the signal over the display；Liquid level sensor 3 is arranged determines volume described
On 4 inner roof wall of liquid case, therefore, the liquid level sensor 3 send signal one described determine to be loaded with well workover in volume liquid case 4
Liquid；
Second electrically operated valve 5 is opened, the outlet tube, which is connected to, to be waited in well workover, and workover fluid, which enters, to be waited in well workover；
It is repeated several times；Since the volume for determining volume liquid case 4 is fixed；Therefore：It is arranged and described determines volume liquid case 4
Volume is V；Setting number is N；
The total volume V of additionAlways=V*N.
