DJK Multifunctional Wellhead

"Multifunctional wellhead" analyses the advantages and disadvantages of the various types of injection wellhead. It is a patented product after several years of improvements and perfection. Its main components are crossbar and tubing head. They together sealed the cylinder. Under that is a wide angel conical seat that supported the tube. And in case of dislocation, the exportation of the crossbar that connect the drill tubing and the drive pipe are not in the identical plane. Tubing head can be divided into two types: Fixed and rotary. The former, which is composed by cylinder tubing hanger, the pressure ring and flange, is used in conventional and water injection well. The latter one is composed by two pylome cylinder tubing hanger, flange, thrust ball bearing and small upper valve. It is applicable to eccentric tests, electric submersible pump cables and hot electric cables and some other special processing requirements. The flange of them can both directly connect with the hoops head and the tire of the blowout suppression box. The flange spiral pitch and big tire are both CYb-250. Therefore, we may choose and combine different production process in accordance with the customers' needs.

Characteristics:
1There is no need to disassemble the ground pipeline in any operation.
2The tubing head, though may under gravity and pressure, will not be squeezed into the crossbar.
3The height of the production tree approximately reduced by 60% compared to the original one. Any operation can be carries on the ground
4With the top flange wire removed, the number of the removable parts and the operational workload are reduced.
5As the height is lowered, the pump stroke efficiency is highly enhanced.
6In case of the blowout, as oil pipelines has not been removed, it can go into production when the tubing head is blocked in.
7Choose the rotary tubing head and there is no need to the remove the flange bolts. With a crowbar inserted in the side hole, the tubing head can rotate up to 360 ° . This can relieve the drill tubing from the winding of steel wire in eccentric test.
8Oil production worker regular rotation tubing head in case of lopsided wear of the deep well pump rod line.
9Compared with the original wellhead, its price is much lower and saves a lot of production costs.
