Description
Technical field
The utility model belongs to the oil and gas well drilling equipment technical field, relates in particular to a kind of drilling well IBOP protective system.
Background technique
IBOP is indispensable vitals in oil and gas well drilling preventer device.The well drilling top drive device is when the abnormal conditions such as generation electrical network outage suddenly, and the IBOP that has closed often can open automatically, causes mud to leak.By analyzing, above-mentioned situation is that the oil hydraulic cylinder due to IBOP bears larger active force.In prior art, need the length of the hydraulic rod of the real oil hydraulic cylinder that join IBOP for the protection crank, crank easily deforms under larger stress when in use, has potential safety hazard when changing accessory.
The model utility content
The utility model provides a kind of rational in infrastructure, the effective drilling well of protection IBOP protective system for solving the technical problem that exists in known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: drilling well comprises three position four-way directional control valve and fuel tank with the IBOP protective system, between is provided with in-line and return line, described in-line is provided with oil hydraulic pump and relief valve, the filler opening of described oil hydraulic pump is connected to by pipeline below the liquid level of described fuel tank, and the oil outlet of described relief valve is connected to described three position four-way directional control valve; Be provided with two oil feed lines between the oil hydraulic cylinder of described three position four-way directional control valve and IBOP, wherein oil feed line is connected to the hydraulic fluid port of described oil hydraulic cylinder rear end, another oil feed line is connected to the hydraulic fluid port of described oil hydraulic cylinder front end, is equipped with one-way valve on described two oil feed lines; Also comprise two groups of pressure regulation pipelines, described pressure regulation pipeline is provided with equilibrium valve and one-way valve, the outlet of described equilibrium valve is connected between the above three position four-way directional control valve of oil feed line and described one-way valve, and the entrance of described one-way valve is connected between the above three position four-way directional control valve of another oil feed line and described one-way valve.
Advantage of the present utility model and good effect are: IBOP protective system of the present utility model is by providing a kind of oil-way system rational in infrastructure to make top driving device IBOP close at work stable off state of rear maintenance; by the cooperation between three position four-way directional control valve, one-way valve and pressure regulation pipeline; make the pressure of oil hydraulic cylinder front-end and back-end keep stable, avoided IBOP to close the rear mud leakage problem that causes because of electrical network outage suddenly.In addition, this protective system can be removed electricity with each solenoid valve after IBOP closes, extended working life.
Preferably: be provided with one-way valve between described relief valve and return line.
Preferably: be provided with pressure-measuring point on described equilibrium valve.
