VIEW DETAILSRockySea Petro Mud PumpDescriptionIn the operation of using rotary drilling method to drill oil and natural gas wells, the drilling reciprocating pump is used to pump drilling fluid, i.e. mud, to circulate and flush the well. During drilling, the mud pump injects mud into the wellbore along with the drill bit, playing a role in cooling the drill bit, cleaning drilling tools, fixing the wellbore wall, driving drilling, and bringing rock cuttings back to the surface.So drilling pumps are usually

Advantage
RockySea Petro has extensive experience in manufacturing Cementing head, and our products have the following advantages.
1. The main body is made of thick walled seamless pipes, which are high-pressure resistant and have a long service life.
2. Equipped with quick fitting joints, it is easy to connect on site and can be connected to API long round buckles/short round buckles/trapezoidal buckles, with a wide range of applications.
3. The dual indicator structure accurately displays the passage of the rubber plug, making it easy for operators to make judgments.
4. The double balance pipe structure ensures that the pressure on both ends of the rubber plug is the same when using the lower interface for cementing operations, eliminating the impact of negative pressure suction on the stopper pin and making it easy to open the stopper pin.
5. The top cover and union nuts adopt large pitch trapezoidal threads, making disassembly and assembly convenient.
Structure
Mainly including cement head cylinder, top cover, plug valve, balance pipe, indicator, union interface, quick fitting joint, spiral stopper pin.
Principle
When multiple cement trucks work together, the cement head is pre filled with rubber plugs for cement injection, including upper and lower rubber plugs. Before injecting cement slurry, first put in the lower rubber plug. After the predetermined amount of cement slurry is injected, put in the upper rubber plug, and then replace it with mud or water to lower the upper rubber plug. The lower rubber plug is blocked by the support ring, and the partition in the center hole is broken until all the cement slurry is squeezed out of the casing. When the upper and lower rubber plugs collide, the liquid channel is blocked, and the pump pressure suddenly increases. The cement injection operation ends. After the cement injection is completed, close the gate leading to the outside of the cement head and remove the connecting pipeline. Wait for 12 hours to solidify, then use logging to detect the return height, and after waiting for 48 hours, perform pressure testing to check the quality of cementing.
Description
Cement head is a specialized tool used for injecting mud and releasing rubber plugs. It is a device installed at the top of the casing during cementing. The cement head can be equipped with one or two rubber plugs at the same time, and the double plug cement head can be used for conventional double plug cementing or continuous two-stage cementing operations.
RockySea Petro: A Pioneer in Cement Head Manufacturing in China
Cement head refers to the cementing device installed at the top of the casing to connect the casing and surface manifold during cementing and injection. The cement head can be used to complete operations such as circulation, injection of isolation fluid, injection of mud, release of rubber plugs, and slurry replacement, making it the main hub of the surface manifold and wellhead for cementing operations.
RockySea Petro can provide various cement head to fit different client needs.
