Product Introduction
A drilling tool powered by drilling fluid, a downhole motor converts liquid pressure into mechanical energy. Mud from the pump enters the motor, causing pressure changes that make the rotor rotate around the stator axis. This rotation is then transferred to the drill bit through shafts, enabling drilling to occur. Downhole motors are frequently utilized in oilfields and coal mines for drilling and workover activities.
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 robust downhole motor is being utilized in the exploration of a deep reservoir within a large oil field. The reservoir is known for its tough formation, high temperatures, and complex geological structure. Traditional downhole motors have struggled in this environment, leading to inefficiencies in the drilling process. The new downhole motor is made from materials that can withstand high temperatures and possess high strength, along with an optimized design. In practical use, this new motor can handle more than double the feed volume of traditional tools, eliminating any interruptions in drilling due to tool failure and significantly improving drilling efficiency.
In directional drilling projects in offshore oilfields, durable downhole motors are paired with advanced guidance systems. Given the high costs associated with offshore operations, efficiency and accuracy are crucial. This downhole motor is able to precisely control the trajectory of the borehole, reducing the need for unnecessary corrections. Through this project, numerous high-precision directional wells have been successfully drilled, with an oil formation encounter rate exceeding 90%, demonstrating the effectiveness of this technology.
