The invention discloses an offshore oil filled type well drilling safety valve, which is provided with an upper flange, a middle pipe, an energy storage device, the sensing device, a cylinder body, a motion mechanism, a lower flange, and flange bolts; the sensing device for acquiring signals of abnormal internal and external pressures of the stand pipe is arranged on the middle pipe and is connected with the energy storage device; the energy storage device transmits power to the motion mechanism; and the motion mechanism is arranged on the cylinder body and can move a valve switch up and down to perfuse the sea water into the device. When the internal and the external pressures of the stand pipe have abnormal fluctuations, the sensing device acquires the signals and transmits an action command to the energy storage device to excite the action mechanism to run so as to perfuse the sea water into the device and balance the internal and the external pressures for protecting the bored well. The device has the advantages of reasonable structure, quick connection, short response time and good stability.

Background technology
Along with development of Chinese economy, especially petrochemical industry and rapid development of automobile industry, the situation that oil and natural gas is under-supply is severeer.In view of the exhaustion day by day of land oil resource, the worldwide strategy and policy of economic development have all been aimed at the ocean, and development offshore oil industry becomes the important goal of various countries' energy strategy.Now, the offshore oil drilling well depth of water has surpassed 3000 meters, and to darker waters development.So working under the depth of water environment, as the lose returns situation occurring, will cause caving in of riser systems, causing immeasurable loss.
Filling type drilling safety valve is to ensure the requisite nucleus equipment of operation on the sea safety.When strata pressure disappearance or the separation of standpipe device, a large amount of situations about running off of mud in the standpipe device all can appear, and as untimely filling, the vacuum state of inner formation very easily causes caving in of riser systems, and major accident takes place.Therefore, in order to reduce drilling cost, guarantee the essential safety of drillng operation, must use suitable safety device to the emergency situations of mud loss at floating drilling platform.Such device research still belongs to blank at home.
Summary of the invention
The present invention seeks to design a kind of new-type deepwater environment and possess the underwater safety valve of filling function; in the time of can taking place for the unexpected loss of mud in the drilling process neutral tube; utilize seawater balance external and internal pressure; prevent that standpipe from caving in; play the effect of protection drilling safety, can satisfy the requirement of marine environmental protection again.
For achieving the above object, overall conception of the present invention is when standpipe inside and outside differential pressure generation unusual fluctuations, and sensing device is collected signal, transmits action command to energy storage equipment; The energy storage equipment transmitting power excites the actuating mechanism operation to hydraulic mechanism, realizes that seawater is filled into device inside, balance external and internal pressure protection drilling safety.
The offshore oil drilling vertical tube pressure equilibrium method; it utilizes sensing device to collect standpipe external and internal pressure signal and transmits action and is filled into riser interiors to the valve mechanism realization seawater that excites actuating mechanism to open on the standpipe, and balance standpipe external and internal pressure is with the protection drilling safety.
A kind of offshore oil filling type drilling safety valve, it has upper flange, intervalve, energy storage equipment, sensing device, cylindrical shell, motion, lower flange, flange bolt; The sensing device of collecting standpipe external and internal pressure abnormal signal is installed on the intervalve and with energy storage equipment and is connected, the energy storage equipment transmitting power is to motion, and motion is installed in the drive valve switch that can move up and down on the cylindrical shell and realizes that seawater is filled into device inside.
Be distributed with auxiliary line on the upper flange of drilling safety valve and the lower flange circumference.Auxiliary line comprises that throttling/kill line, mud supercharging pipeline, hydraulic pressure transfer line, chemical agent inject one or more combination of pipeline.
At intervalve the safety valve positioner is housed, safety valve positioner one end is connected with energy storage equipment, and an other end is located at intervalve.
Energy storage equipment is by hydraulic mechanism transmitting power motion.
Motion is positioned at the safety valve cylindrical shell, and motion one end is connected with energy storage equipment by hydraulic mechanism and the switch of realization to water intaking valve on the safety valve cylindrical shell that move up and down in the safety valve cylindrical shell.
Advantage of the present invention: topology layout is reasonable, connect quick, response time weak point, good stability, can be in the advantage of offshore boring island control etc.Can be applied to deep water, super deepwater drilling operating environment well, have good Practical Performance and higher macroeconomic performance.In deepwater drilling operation safety device few in number, its design feature, mode of occupation have clear superiority.
