API Oilfield Downhole Tools Drill Pipe Float Valve For Oil Drilling With Plunger And Flapper Type With Repair Kit

________________________________________

Product Description:

The drill float valve produced and sold by our company Huichi Petro is a special valve installed on the drill string. It is a blowout prevention tool installed in the drill string near the drill bit end. It is connected to the drill string through the float valve housing. It is mainly used to control the flow direction and pressure of the drilling fluid. It can automatically open or close according to the pressure of the drilling fluid. It is used to cool the drill bit and clean up drilling waste. By automatically adjusting the flow direction of the drilling fluid, the float valve helps to balance the pressure of the liquid between the drill pipe and the casing, thereby reducing the risk of well kick accidents. The float valve also has the function of preventing mud from flowing back, preventing mud from bringing in drill cuttings and sediment backflow, blocking the drill bit water hole, so that the mud can only flow from top to bottom in the drill tool, preventing waste and cuttings in the well from being brought to the ground. When a blowout or well kick occurs, the pressure at the bottom of the float valve is greater than the pressure of the upper liquid column, and the float valve cover automatically closes the water hole, so that the formation fluid cannot enter the upper part of the float valve in the drill tool, preventing overflow and well kick in the drill tool.

Structural composition:

The drilling tool float valve produced and sold by our company Huichi petro consists of a valve body, a seal, a valve core, and a float. Its design combines advanced domestic and foreign float valve technologies, and has made improvements to existing technical difficulties, such as reinforcing the stability of the pin and optimizing the flexibility of the spring, thereby extending the service life and improving the reliability and durability of the equipment.

The float valve joint structure is divided into two types: plate-type float valve joint and arrow-type float valve joint.

1. Valve body: Made of high-strength metal material, it has good pressure resistance and corrosion resistance, and can withstand high pressure and harsh environment during drilling.
2. Valve core: It is the core component of the float valve. The valve core is connected to the float through a connecting rod or other mechanism, and can move up and down according to the pressure and buoyancy changes of the drilling fluid, thereby controlling the opening and closing of the valve.
3. Float: Its density is less than that of the drilling fluid. The float is connected to the valve core through a connecting mechanism. When the drilling fluid pressure changes, the float will float up and down in the drilling fluid, driving the valve core to move.
4. Seals: including valve seat seals, valve core seals, etc., usually use high-performance rubber or metal sealing materials to ensure the sealing performance of the valve under high pressure.

Working principle:

During normal drilling: the float valve is in the open state, the drilling fluid enters the drill string through the float valve under the action of the pump, and then sprays out from the drill bit, carrying the drill cuttings back to the ground. At this time, the float is in a higher position under the buoyancy of the drilling fluid, the valve core is open, and the drilling fluid can pass smoothly.

When the pump is stopped or the pressure in the well is abnormal: when the drilling pump stops working or the pressure in the well suddenly increases, the flow rate of the drilling fluid decreases or stops, and the float sinks under its own gravity, driving the valve core to close, preventing the drilling fluid from flowing back into the well, thereby preventing accidents such as blowouts.

Function:

1. Preventing blowouts: The float valve can be quickly closed when the drilling pump stops working or the pressure in the well is abnormal, preventing the drilling fluid from flowing back, effectively preventing the occurrence of blowout accidents, and ensuring the safety of drilling operations.
2. Balanced pressure: By controlling the flow direction and pressure of the drilling fluid, the float valve can help balance the pressure in the well and reduce the probability of accidents such as leakage and stuck drill.
3. Improve drilling efficiency: The existence of the float valve can make the drilling fluid form a stable circulation in the drill string, improve the carrying capacity of the drilling fluid, and speed up the discharge speed of drill cuttings, thereby improving drilling efficiency.
