Tool Introduction:

The FP6-35 hydraulic control single gate shear preventer is used to forcibly cut off the drilling tools inside the well in emergency situations to achieve the purpose of sealing the well. It is used to cut off the drilling tools inside the well and control the wellhead when the blowout is out of control due to tool failure or bending deformation of the drilling tools at the joint, and other measures cannot be taken to control the wellhead. The anti spray device has a simple structure, easy use and maintenance, and simple and reliable operation.

The blowout preventer mainly consists of a main housing, a pair of gate assemblies that move towards each other inside the main housing, a screw rod, an end cap, a handwheel, a lower joint, and components such as a king nut. When cutting is required, the piston is driven by hydraulic pressure to move the gate body towards the center of the wellbore. With the joint action of the two blades, the optical fiber in the well can be cut, and the gate body can be locked in the closed position. When opening the well, turn the locking handwheel counterclockwise to fully retract to the initial position, and then the well can be opened.

be careful:

When opening and closing, it should be ensured that the baffle is fully open to prevent collision between the instrument and the gate. There is a guide limit pin on the shell, which is used to cooperate with the guide groove on the gate body to prevent the gate body from rotating in the circumferential direction during operation. The gate body is equipped with a guide groove, which is used to allow the pressure inside the well to enter the rear of the gate and push the gate towards the center of the wellbore, playing a role in co pressure and sealing assistance.
