Application Scenarios:
This motor is primarily applied in drilling projects where the use of drilling fluid is restricted or environmentally sensitive. It is widely utilized in underbalanced drilling (UBD) and managed pressure drilling (MPD) operations for oil and gas fields, especially in low-pressure, low-permeability reservoirs and depleted reservoirs to avoid formation damage caused by fluid invasion. Additionally, it is suitable for drilling operations in environmentally sensitive areas such as desert oases, offshore protected zones, and farmland regions, where the zero-discharge of drilling fluid can minimize environmental pollution. The motor also plays a critical role in geothermal well drilling, coalbed methane (CBM) development, and shallow gas well drilling, as well as in emergency rescue drilling projects that require rapid drilling with clean power medium.
Product Advantages:
Firstly, it enables environmentally friendly drilling operations—using clean gas as the power medium eliminates the need for large-volume drilling fluid, avoiding soil and water pollution caused by drilling fluid leakage, which meets the strict environmental protection requirements of sensitive areas. Secondly, the motor reduces formation damage significantly; the gas-driven mode maintains underbalanced conditions in the wellbore, preventing fluid invasion into reservoir pores and fractures, thus protecting the reservoir's permeability and improving oil and gas production capacity. Thirdly, it exhibits high drilling efficiency in specific formations—compressed gas has strong carrying capacity for cuttings, which facilitates the timely removal of downhole cuttings and avoids cuttings deposition, ensuring continuous and efficient drilling. Moreover, the motor features a relatively simple structure with fewer vulnerable components related to fluid treatment, reducing maintenance difficulty and operational costs. Finally, it adapts to narrow wellbore spaces and remote drilling sites, as the gas supply system is more flexible and easier to deploy compared to large-scale drilling fluid circulation systems, enhancing operational mobility.
