Abstract
The utility model relates to a special pressure testing blind plate of a blowout preventer for an oil field. The technical scheme of the special pressure testing blind plate is as follows: the special pressure testing blind plate mainly consists of a pressure testing pipe column connecting thread, a guide connector, a high-pressure dust, a positioning hole and a blind plate, the protrudent guide connector is arranged on one side of the blind plate, the communicating high-pressure dust is arranged in the guide connector and the blind plate; and the positioning hole is formed on one end of the blind plate. The special pressure testing blind plate has the advantages that the special pressure testing blind plate can guide the blowout preventer to safely stably sit on the pressure testing blind plate and a pressure testing clamp, when in pressure testing of the blowout preventer, the pressure testing blind plate is connected with a pressure testing pipe column, thereby completely simulating the actual downhole situation and avoiding accidents.
Description
One, technical field:
The utility model relates to a kind of preventer instrument, the special-purpose blind plate of particularly a kind of preventer pressure testing.
Two, background technology:
At present in oil drilling, well head must be installed preventer, according to related standards, situation under must simulation well after the preventer maintenance is carried out pressure testing, ram preventer partly seal pressure testing the time, need the pressure testing tubing string with the simulation downhole tool, pressure testing tubing string commonly used now forms with one section drilling rod and certain thickness steel plate welding production.In the process of pressure testing, the pressure that the pressure testing tubing string is born acts on the flashboard of preventer, and what increased flashboard helps envelope power, and this does not conform to the actual conditions of down-hole; Be to ftracture easily on the other hand, drilling rod is flown out, cause the accident with the pressure testing tubing string that one section drilling rod and certain thickness steel plate welding production form.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of preventer pressure testing special-purpose blind plate, and when the preventer pressure testing, PRESSURE TESTING BLIND FLANGE is connected with the pressure testing tubing string.
Its technical scheme is: mainly be made of pressure testing tubing string connecting thread, navigation sub, high pressure duct, pilot hole and blind plate, a side of described blind plate is provided with the navigation sub of projection, is provided with the high pressure duct of connection in described navigation sub and the blind plate; One end of described blind plate is provided with pilot hole.
Above-mentioned blind plate is provided with steel ring slot.
The beneficial effects of the utility model are: the utility model can be guided the seat of preventer safety and stability on PRESSURE TESTING BLIND FLANGE and pressure testing clip, and when the preventer pressure testing, PRESSURE TESTING BLIND FLANGE is connected with the pressure testing tubing string, has simulated the actual conditions of down-hole fully and has avoided accident.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: pressure testing tubing string connecting thread 1, navigation sub 2, high pressure duct 3, steel ring slot 4, pilot hole 5, blind plate 6, connecting thread 7.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: mainly be made of pressure testing tubing string connecting thread 1, navigation sub 2, high pressure duct 3, pilot hole 5 and blind plate 6, one side of described blind plate 6 is provided with the navigation sub 2 of projection, is provided with the high pressure duct 3 of connection in described navigation sub 2 and the blind plate 6; As shown in the figure, an end of blind plate 6 is provided with pilot hole 5, steel ring slot 4 and connecting thread 7.By pressure testing tubing string connecting thread PRESSURE TESTING BLIND FLANGE and pressure testing tubing string are coupled together, navigation sub mainly is to guide the seat of preventer safety and stability on PRESSURE TESTING BLIND FLANGE, the high pressure duct is connected with test pump, and pilot hole makes PRESSURE TESTING BLIND FLANGE and pressure testing clamp connection together, prevents the PRESSURE TESTING BLIND FLANGE rotation.
Its principle of work is: preventer when mounted, the navigation sub of PRESSURE TESTING BLIND FLANGE can guide the preventer safety and stability the seat on PRESSURE TESTING BLIND FLANGE and pressure testing clip; Preventer is when pressure testing, the water that test pump pumps enters the inner chamber of preventer by the high pressure duct, and under the effect of hydraulic coupling, the pressure that the pressure testing tubing string is subjected to acts on the PRESSURE TESTING BLIND FLANGE, and do not act on the flashboard of preventer, simulated the actual conditions of down-hole fully.
Claims (2)
