Product Introduction
Downhole motor is a positive displacement downhole power drilling tool that uses drilling fluid as power and converts liquid pressure energy into mechanical energy. When the mud pumped out by the mud pump enters the motor, a pressure drop is formed at the inlet and outlet of the motor, pushing the rotor to rotate around the axis of the stator, and transmits the torque and speed to the drill bit by universal shaft and transmission shaft, thereby realizing drilling operation. Downhole motor is extensively used in drilling and workover for oilfields and coal mines.
Our Advantage
Increased drilling speed: Compared with the traditional rotary drilling method, screw drilling tools can directly convert the hydraulic energy of the mud into mechanical energy, providing stable rotary power to the drill bit. This direct power transfer allows the drill bit to operate at a more stable rotational speed and torque downhole, thus increasing drilling speed. For example, in some soft to medium-hard formations, the use of screw drilling tools can increase mechanical drilling speeds by 30% - 50%.
Directional Drilling Capability: Screw drilling tools offer unique advantages in field development, especially for drilling horizontal and directional wells. By combining them with Measurement While Drilling (MWD) and guiding tools, the trajectory of the borehole can be precisely controlled. When drilling horizontal sections, screw drilling tools are able to follow a pre-set trajectory, reducing borehole deviation and increasing the rate of oil formation encounters.
Product Uses
A new type of durable downhole motor is used in the development of a deep reservoir in a large oil field. The reservoir formation has high hardness, high temperature and complex geological structure. Conventional downhole motor often fail during the drilling process, resulting in low drilling efficiency. The new downhole motor adopt high-temperature-resistant and high-strength materials and optimised structural design. In practical application, the feed volume of a single tool is more than twice that of the traditional tools, and there is no up and down drilling caused by tool failure during the whole drilling process, which greatly improves the drilling efficiency.
In directional well drilling projects in offshore oilfields, durable downhole motor are used in conjunction with advanced guidance systems. Due to the high cost of offshore platform operations, drilling efficiency and accuracy are required. This downhole motor can accurately control the trajectory of the borehole, reducing unnecessary borehole correction operations. In this project, a number of high-precision directional wells were successfully drilled, and the oil formation encounter rate reached more than 90%, about 20% higher than before.
