Downhole Screw Motor
Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.
The downloe screw motor is a type of downhole power tool which takes power from the fluid and then translates fluid pressuire into mechanical enery. When powe fluid flows into the screw motor, the p[ressrue diffference built between the motor inlet and outlet can rotate the rotor within the stator, providing necessary torque to the drill bit below to start penetration. The downhole motor is suitable for vertical, directional and horizontal wells.
Features:
1. The Torque generated by the screw motor only turns the drill bit, which can dramatically decrease drill pipe wear;
2. The screw motor can be incorporated into special BHA to realize high built-up rate or screwed to orientating tool to perform continuously controlled kick off;
3. Output torque of the screw motor is in linear relationship with drilling fluid differential pressuire generated by the hydraulic motor;
4. Screw motor with hollow rotor allows for large flow rate, which then leads to accelerated flowback speed and sand carrying capacity;
5. Standardized screw motors in different series as available for various types of drill bits.
