‌RockySea Petro F Series Mud Pump

Data sheet

Function

1. Cool the drill bit and lubricate the rotating drill string.

2. Remove rock debris from the bottom of the well and send it back to the surface;

3. Balance or control the pressure of oil, gas, and water layers in the drilled well section to prevent blowout;

4. Make mud cakes on the wellbore to prevent collapse;

5. Handle complex underground situations. When encountering fractured formations, pump in plugging materials, and when encountering stuck drilling, pump in crude oil and diesel to release the stuck.

Feature

Compared with traditional products, F series of RockySea Petro mud pump has the following characteristics:

1. Abandoning the packing box seal at the center pull rod and replacing it with a rubber expansion sleeve prevents lubricating oil from seeping into the water tank of the sprinkler system, preventing unnecessary loss of lubricating oil. This not only saves lubrication costs but also reduces environmental pollution caused by lubricating oil during drilling

2. The lubrication system of the crosshead has been improved by adding an oil circuit, ensuring that there is sufficient lubricating oil between the crosshead and guide plate to reduce friction during the operation of the mud pump. This improvement greatly extends the service life of the crosshead and guide plate, reduces their repair and replacement times, improves drilling efficiency, and reduces drilling costs.

Description

Mud pump is an important component of drilling rig and a key equipment in the drilling mud circulation system. The two main parameters of mud pump performance are displacement and pressure.

The displacement is calculated by discharging several liters per minute, which is related to the drilling diameter and the required flushing fluid velocity from the bottom of the hole. That is, the larger the hole diameter, the greater the required displacement. The upflow speed of the flushing fluid is required to timely flush the rock cuttings and powder cut by the drill bit off the bottom of the hole and reliably carry them to the surface. During geological core drilling, the upward velocity is generally around 0.4-1 meters per minute.

The pressure of the mud pump depends on the depth of the borehole, the resistance of the channel through which the flushing fluid passes, and the properties of the flushing fluid being transported. The deeper the drilling, the greater the pipeline resistance and the higher the required pressure. As the drilling diameter and depth change, the pump displacement should also be adjustable at any time.

There is a gearbox or hydraulic motor in the pump mechanism to adjust speed and change displacement. In order to accurately grasp the changes in pump pressure and displacement, a flow meter and pressure gauge should be installed on the mud pump, so that drilling personnel can understand the operation of the pump at any time. At the same time, the condition inside the hole can be judged by pressure changes to prevent accidents inside the hole.
