What are the applications of miniature hydraulic piston pumps in the petroleum field?
Miniature hydraulic piston pumps have numerous applications in the petroleum field, which are as follows:

1.Petroleum Exploration:
Geological Sample Collection: During the process of petroleum exploration, it is necessary to collect geological samples such as rocks and soils from underground for analysis. Miniature hydraulic piston pumps can provide precise power for sampling equipment, ensuring the smooth progress of the sampling process. For example, in some sampling tools that need to go deep underground, miniature hydraulic piston pumps can drive the drill bits to rotate and advance, thus enabling the collection of accurate geological samples, which provides a basis for the subsequent assessment of petroleum reserves and the formulation of exploitation plans.

Driving of Downhole Measurement Tools: Petroleum exploration requires the use of various downhole measurement tools, such as logging tools and sensors. These tools usually need to work in harsh downhole environments. Miniature hydraulic piston pumps can provide stable hydraulic power for these measurement tools to ensure their normal operation and accurate data collection. For example, in high - temperature and high - pressure downhole environments, the miniature hydraulic piston pump can drive the probes of logging tools to rotate, extend and retract, etc., thereby realizing the accurate measurement of downhole geological information.

2.Drilling Operations:
Drilling Fluid Circulation System: Drilling fluid plays crucial roles such as cooling the drill bit, carrying cuttings, and balancing the formation pressure during the drilling process. Miniature hydraulic piston pumps can be used to drive the pumps in the drilling fluid circulation system, pumping the drilling fluid from the ground into the wellbore and then returning the drilling fluid carrying cuttings from the wellbore back to the ground. This can ensure the smooth progress of the drilling process and improve the drilling efficiency and safety.

Bit Drive: The drill bit is a key component in drilling operations and requires powerful force to drive its rotation and penetration. Miniature hydraulic piston pumps can cooperate with other hydraulic equipment to provide sufficient torque and rotational speed for the drill bit, enabling it to drill smoothly in hard rock formations. For example, in some directional drilling and horizontal drilling operations, miniature hydraulic piston pumps can accurately control the drilling direction and speed of the drill bit, improving the accuracy and efficiency of drilling.

3.Completion Operations:

Control of Packers and Safety Valves: During completion operations, equipment such as packers and safety valves are required to ensure the safety and stability of the oil well. Miniature hydraulic piston pumps can provide precise hydraulic control for these devices, ensuring that they can be opened and closed in a timely manner when needed. For example, in the event of an abnormal situation in the oil well, the miniature hydraulic piston pump can quickly drive the safety valve to close, preventing accidents such as blowouts.

Operation of Downhole Tools: Various downhole tools are needed during completion operations, such as casing cutters and tubing hangers. Miniature hydraulic piston pumps can provide power for these tools, enabling them to perform various operations downhole. For instance, during casing cutting operations, the miniature hydraulic piston pump can drive the blades of the cutter to rotate, thus cutting the casing to the required length.

4.Petroleum Transportation:

Pipeline Pressure Boosting: During the process of petroleum transportation, it is necessary to increase the pressure of petroleum to ensure its smooth flow in the pipeline. Miniature hydraulic piston pumps can be used in the pipeline pressure - boosting system to provide additional pressure for the petroleum, enabling it to overcome pipeline resistance and elevation differences and achieve long - distance transportation. For example, in some pumping stations of long - distance oil pipelines, miniature hydraulic piston pumps can be used as auxiliary pressure - boosting equipment to improve the pipeline's transportation capacity.

Valve Control: A large number of valves are required in petroleum transportation pipelines to control the flow direction and flow rate of petroleum. Miniature hydraulic piston pumps can provide hydraulic power for the driving mechanisms of the valves to ensure that the valves can be opened and closed accurately and quickly. This can achieve precise control of petroleum transportation and improve transportation efficiency and safety.
