Abstract
The utility model relates to a sealed blowout preventing box which is used for preventing the leaking of drilling fluid in the process of oil drilling when a drill is lifted up and down. The sealed blowout preventing box is composed of a box body, connecting hinge pins, reinforced steel plates, sealing fasteners, sealing rubber, screws and a fluid discharging valve, wherein the box body is in a cylinder shape as a whole, drilling tool sleeve holes are arranged at the centers of the top surface and the bottom surface of the box body, the sealing rubber is fixedly arranged at the inner sides of the drilling tool sleeve holes by the screws, two semi-cylindrical box bodies are connected by the connecting hinge pins; the reinforced steel plates are arranged at the side surfaces of the box body, and the fluid discharging valve is arranged at the bottom of the side surface of the box body. When in use, the sealed blowout preventing box is sleeved on a drill rod coupling, sealing locking strips and sealing fasteners are locked together, and the fluid discharging valve is opened by a hose into a protecting umbrella below a drilling floor. The sealed blowout preventing box eliminates the waste of the drilling fluid, avoids the harm to operators and a device, and is safe and environmental-friendly.
Description
Technical field
The utility model relates to a kind of sealing blowout prevention box, is mainly used in oil drilling, prevents that when making a trip drilling fluid from leaking, and belongs to the well head aid of petroleum drilling engineering.
Background technology
At present, in the Process of Oil Well Drilling, make a trip when changing drilling tool drilling rod or pipe trips out, when box cupling releases, drilling fluid in drilling rod or the pipe can leak and spray, and causes the pollution of offshore boring island and the waste of drilling fluid, and the equipment to operating personnel and periphery causes damage simultaneously, especially also can make that the rig floor face is wet and slippery winter, form the potential safety hazard of construction.
The utility model content
The purpose of this utility model is to provide a kind of sealing blowout prevention box; sealing blowout prevention box can prevent in the drilling process because of making a trip, change leaking and spraying of drilling fluid that drilling tool causes; make the outer drilling fluid that releases all be connected in the blowout prevention box; and enter in the umbrella; stopped the drilling fluid waste; simultaneously effectively avoid injuring operating personnel and equipment, make that the rig floor face is clean, neat, environmental protection.
The utility model adopts following technical scheme, it is a kind of sealing blowout prevention box, by box body, connect bearing pin, strengthening steel slab, the sealing snap close, caulking gum, screw and draining valve constitute, it is characterized in that box body integral body is cylindric, the end face of box body and bottom center have the drilling tool trepanning, box body is made of the box body of two semicircle tubulars dividing equally along box body Cylindorical rod cross section, the same linear edge of the box body side of two semicircle tubulars is provided with the connection bearing pin, the box body of two semicircle tubulars is linked together, another linear edge of the box body side of two semicircle tubulars is respectively equipped with sealing snap close and sealing bolt, by screw caulking gum is fixedly mounted on drilling tool trepanning inboard, the top of the side of the box body of two semicircle tubulars, strengthening steel slab all is equipped with in bottom and middle part, and draining valve is equipped with in the bottom of the side of box body.
Above-mentioned sealing blowout prevention box, the internal diameter of its cylindric box body side is greater than the external diameter of drill pipe coupling or drilling tool box cupling.
Operating principle of the present utility model; tripping out before drilling rod or drilling tool release; this sealing blowout prevention box is sleeved on drill pipe coupling or the drilling tool box cupling; to seal bolt and the dense block padlock is tight; connect in the umbrella of draining valve under the rig floor with flexible pipe, open draining valve, drilling tool releases then; drilling fluid enters in the sealing blowout prevention box, and is back in the umbrella through draining valve and flexible pipe.
The utility model can prevent that drilling fluid leaks in the drilling process, has stopped the drilling fluid waste, avoids the infringement to operating personnel and equipment, makes that the rig floor face is clean, neat, environmental protection.
