Description
Technical field
The utility model belongs to petroleum drilling and mining equipment technology field, can simulate the operation operating mode that different well depths and well are pressed, and is specifically related to a kind of experimental rig of simulating Operating Pressure.
Background technology
The Operating Pressure technology is that a kind of that development in recent years is got up is being with under the pressure ring border; Under the control of wellhead blowout preventor, hoist, press down tubing string by force; Well implement to bore, a kind of new technology of workover treatment; Not only can avoid boring, in the well workover process to the pollution and the injury of payzone, and obtaining maximum protection aspect exploitation potential, output and the environment.At present, this technology is used widely, and shows good economic and social benefit, has become the development trend of current oil field in drilling well or workover treatment.
But, present operation operating mode for different well depths of simulation and different wells pressure, and the device of simulation Operating Pressure does not also have under this operating mode, to the research Operating Pressure, and the service behaviour and the security performance of checking and elevator belt pressure implement, caused inconvenience.
Summary of the invention
The purpose of the utility model provides a kind of experimental rig of simulating Operating Pressure; Solved the experimental rig that prior art is not simulated the different well depths and the operation operating mode of different wells pressures, can't accurately study Operating Pressure, checking and elevator belt and press the service behaviour of implement and the problem of security performance.
The technical scheme that the utility model adopted is; A kind of experimental rig of simulating Operating Pressure; To simulate well head and be embedded in the well, the top mounting strap of simulation well head is pressed implement, is tubing string in the annular space of simulation well head and Operating Pressure equipment; The simulation well head is communicated with compression pump, accumulator respectively, and accumulator is connected with regulator and water tank successively.
The beneficial effect of the utility model is, can be used in the research Operating Pressure, simulation several work operating mode, and under various working, simulate Operating Pressure, and the service behaviour and the security performance of checking and elevator belt pressure implement.
Description of drawings
Fig. 1 is the structural representation of the utility model simulation test device.
Among the figure, 1. simulate well head, 2. compression pump, 3. accumulator, 4. regulator, 5. water tank, 6. pressure line, 7. Operating Pressure equipment, 8. tubing string.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
With reference to Fig. 1; The simulation test device structure of the utility model is will simulate well head 1 and be embedded in the well, the top mounting strap pressure implement 7 of simulation well head 1; In the annular space of simulation well head 1 and Operating Pressure equipment 7 is tubing string 8; Simulation well head 1 is communicated with compression pump 2, accumulator 3 respectively, and accumulator 3 is connected with regulator 4 and water tank 5 successively, forms the circulating system of a sealing.
The operating principle of the utility model is: utilize compression pump to continue, circulate and suppress, through the method for regulator and accumulator regulating system pressure, pressure stable is provided for the simulation well head.Be that the opening pressure pump is suppressed in the annular space of simulation well head and Operating Pressure equipment; Annular pressure by regulator according to situation such as well depth and well pressures; Adjust the pressure environment that needs; Last water gets into water tank through pressure line, forms a sealing, circulation, pilot system with pressure, after system sets up the pressure stable environment, begins to carry out the Operating Pressure simulated test.
Operating Pressure equipment begins Operating Pressure under this band pressure ring border, under the control of wellhead blowout preventor, hoist, press down tubing string by force.But promoting and pressing down in the process, inevitable build-up of pressure fluctuation, pressure compensator is just started working, and remedies pressure oscillation, keeps pressure stability.
The utility model can simulate the operation operating mode that needs, and under this operating mode, simulate Operating Pressure according to situation such as well depth and well pressures, and simulation is true, pressure stability, simple to operate, safe and reliable.
