Adopt the control method of four-phase separator feed liquor mechanism as follows:
If a, the force value in the first feed liquor pipeline are less than or equal to setting value, four-phase separator normally moves, the first feed liquor pipeline circulation;
When b, the pressure in the first feed liquor pipeline surpass setting value, standby feed liquor pipeline is opened, and standby feed liquor pipeline and the first feed liquor pipeline circulate simultaneously;
C, enter sand tank when the drilling fluid after the cabin separation of four-phase separator solid phase, when the liquid level in sand tank surpasses setting value, the 3rd feed liquor pipeline is opened, and the drilling fluid in sand tank is pumped into and in tank, carries out separation;
D, after four-phase separator has moved, in four-phase separator, inject drilling fluid, by reclaim line, the first feed liquor pipeline, standby feed liquor pipeline and four-phase separator, form circulation of drilling fluid.
Below the operating principle of four-phase separator feed liquor mechanism is described:
Four-phase separator 2 utilizes the control of ball valve control valve to only have the first feed liquor pipeline 4 circulations when normal operation, when the pressure that the first feed liquor pipeline 4 detected when pressure sensor 15 surpasses setting pressure, the ball valve of another standby feed liquor pipeline 5 is automatically opened drilling fluid can be entered in four-phase separator 2 from two feed liquor pipelines simultaneously, thereby the pressure of reduction the first feed liquor pipeline 4 makes pipeline in normal pressure limit.
The 3rd feed liquor pipeline 7 is again to be reclaimed and flow into the pipeline circulating in four-phase separator 2 by the remaining drilling fluid that enters sand tank 10 after the solid phase cabin separation through four-phase separator 2, four-phase separator 2 is connected to sand tank 10 by pipeline 9, by another pipeline, sand tank 10 is connected to four-phase separator 2 again, this pipeline 9 is connected in parallel by flange and standby feed liquor pipeline 5, drilling fluid in sand tank 10 is carried out in converging rear inflow four-phase separator 2 with the drilling fluid of standby feed liquor pipeline 5 separated.
When avoiding enabling at the same time the reclaim line 3 of standby feed liquor pipeline 5 and raffinate, the drilling fluid in standby feed liquor pipeline 5 pours into reclaim line 3, and reclaim line ball-and-seat 20 need be installed in reclaim line.It is liquid level sensor 11 that liquid level monitoring arrangement is installed on sand tank 10, carries out in real time liquid level monitoring, and automatically controls the pump valve switch on this pipeline.
After drilling well finishes, because the landwaste in drilling fluid is subject to self gravitation effect meeting under the deposition of the vertical pipeline section bottom of feed liquor pipeline, for fear of the landwaste depositing, by pipeline blockage, designed two kinds of structures and the landwaste of feed liquor pipeline section has been removed clean.First the leakage fluid dram of four-phase separator 21 is connected to the first feed liquor pipeline 4 by one section of pipeline, and reclaim line ball-and-seat 20 is installed.After termination of pumping, the liquid inlet control valve of closing the first feed liquor pipeline 4 is the first horizontal pipeline section control valve 18, can make the clean drilling fluid of part circulate in pipeline, can constantly rinse the landwaste of deposition in the vertical pipeline section of feed tube in cyclic process.Secondly, at the vertical pipeline section of feed tube and the intersection of horizontal pipeline section, designed four-way pipeline structure, both can alleviate the erosion corrosion to pipeline turning point in drilling fluid separation process, also can when termination of pumping, the flange in the bottom blind plate of four-way pipeline be opened the landwaste of deposition is discharged, guarantee the clean and unobstructed of pipeline.On every feed liquor pipeline, flow meter is installed, constantly monitors each pipeline inner fluid flow situation, for system reliability service provides safeguard simultaneously.
Below in conjunction with accompanying drawing 2, be described further.Figure 2 shows that four-phase separator feed liquor structural scheme of mechanism for drilling well.
From the drilling fluid returning out in well, from mechanism's inlet 19, enter feed liquor mechanism, if the first feed liquor pipeline 4 force value that pressure sensor 15 detects are less than setting value, in normally-pressured neighbor, the first vertical pipeline section control valve 16 is opened drilling fluid is flowed in four-phase separator 2 from the first vertical pipeline section, and standby vertical pipeline section control valve 6 and other valve are in closing.
When the force value detecting when pressure sensor 15 surpasses setting value, standby vertical pipeline section control valve 6 is automatically opened drilling fluid is entered in four-phase separator 2 with standby vertical pipeline section from the first vertical pipeline section simultaneously.The liquid level that liquid level sensor 11 on sand tank 10 detects surpasses setting value, open the 3rd vertical pipeline section control valve 8, start pipeline pump 12, remaining drilling fluid in sand tank is again pumped in four-phase separator 2 and carries out separation, and pipeline ball-and-seat 13 prevents that the drilling fluid in standby vertical pipeline section is back to the 3rd vertical pipeline section.
After four-phase separator 2 has normally moved, the drilling fluid clean to the interior injection of four-phase separator 2 participates in circulation, open reclaim line control valve 22, close the first horizontal pipeline section control valve 18, start reclaim line pump 21, make drilling fluid along reclaim line 3, flow into the first vertical pipeline section and standby vertical pipeline section from leakage fluid dram 1.It is circulated in four-phase separator, thereby pour in four-phase separator with sand setting and the landwaste of standby vertical pipeline section bottom be deposited on the first vertical pipeline section because of Action of Gravity Field, in order to avoid block inlet, affect the four-phase separator normal operation of next time.
Reclaim line ball-and-seat 20 avoids drilling fluid when drilling well directly from mechanism's inlet 19, to scurry into reclaim line 3.In addition, the four-way structure of feed liquor pipeline section bottom design can be opened the blank flange of bottom, and the landwaste of deposition is discharged from flange port.Three feed liquor pipelines are all provided with flow meter 17, monitor flow situation in each pipeline.
