Apparatus and methods for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure. To allow the drill string to be removed from the casing, the pressure produced by the formation can be bled off and the drill string removed for servicing. The drill string can then be reinserted, the pressure in the casing above the deployment valve applied to preferably equalize pressure above and below the valve and the drill string run into the hole for further drilling.

A centrifugal backspin braking system located on the input shaft and actuated only in the backspin direction and a gear drive between the input shaft and output shaft are provided.

When a current flows through a battery, a resistance loss proportional to the square of the current is produced by an internal resistance component of the current. In a case where the temperature of a heat capacity element is raised, a charging current is controlled such that prescribed thermal energy is provided to the heat capacity element by this resistance loss. Air is induced into a power supply unit through a vehicle compartment air exhaust duct. Then, the thermal energy stored in the heat capacity element is transferred to the air induced into the power supply unit. The air to which the thermal energy has been provided from the heat capacity element is blown out toward a vehicle compartment space by a fan.

A system and method for safely controlling a well being drilled or that has been drilled into a subterranean formation in which a conventional blow-out preventer operates to close the well bore to atmosphere upon the detection of a fluid influx event. Fluid pressures as well as fluid flow rates into and out of the well bore are measured and monitored to more accurately and confidently determine the fracture pressure and pore pressure of the formation and perform well control operations in response to a fluid influx event. During a suspected fluid influx event, one or more of the fluid flow and pressure measurements are used to confirm the fluid influx event and to safely regain well control by circulating the fluid influx out of the well through a choke line while maintaining the pressure inside the well between specified, selected limits, such as between the fracture and pore pressures.

All the signals are transmitted into the collection instrument to be collected through an RS485 network cable; after data processing is carried out, the data is transmitted to a drill floor parameter display device and a central station host computer through a wireless data transmission device; the data storage, display and print are carried out by the host computer, and the data is simultaneously uploaded into a data platform processor of an upper-level command center; finally, remote control realtime processing and monitoring are carried out on all the well control parameters of all the drilling crews. The intelligent monitoring system has the beneficial effects of realizing omnibearing, long-distance and timely drilling well control, safe production, and playing better role in preventing the occurrence of accidents such as well kick, loss circulation, blow-out, etc.

The present invention relates to a hydrothermal synthesis preparation method of a lithium iron phosphate of an anode material used by a lithium ion battery, concerning a phosphate containing two metals. The step is that a lithium source and a phosphor source are solubilized into the water or mixed with the water and then put into a high pressure kettle. After the air in the kettle is blown out by an inert gas, the high pressure kettle is sealed and heated to a temperature between 40 DEG C and 50 DEG C from a room temperature after being stirred. An inlet valve and a vent valve are opened and then a prepared divalent ferric salt liquor is added in. The high pressure kettle is sealed and the reaction time lasts from 200 minutes to 480minutes at the temperature between 140 DEG C and 170 DEG C. At the time, the inner pressure corresponding to the system is from 0.36 MPa to 0.85 MPa. The mixture rate of the added substance is Li: Fe: P and the mol ratio is 3.0-3.15: 1: 1.0-1.15. When the reaction starts, the reactant concentration is from mol/L 0.2 to 1.0mol/L, computed according to the concentration of the ferrous ion and then the resultant is filtrated, cleaned, dried and coated with the carbon. Finally the lithium iron phosphate product can be obtained. The present invention has the advantages of simple technology, good batch stability, good electrochemical performance and even distribution. The purity quotient can be more than 99 percent and the grain diameter D50 is between1.5Mu m and 2Mum.

A hand-guided electric device has an electric motor for driving a tool. The electric motor has a motor housing with inlet and outlet for cooling air. A blower wheel is driven by the electric motor and cooling air is conveyed into the motor housing with the blower wheel through the inlet and blown out from the motor housing through the outlet. The device housing has a cooling air inlet chamber and a cooling air outlet chamber. The cooling air enters the inlet chamber through a cooling air inlet port in an exterior housing wall of the device housing and exits from the outlet chamber through a cooling air outlet port in the exterior housing wall. The cooling air inlet and outlet chambers are separated from one another substantially air-tightly by an inner housing wall so that motor housing is the only flow connection between inlet and outlet chambers.
