Tianhe Factory Specializes in Producing 12 Inch 340mm Trenchless Hole Opener
Product Description
TIANHE Fixed Diameter Hole Openers are designed for use in soft clays and shales to medium-hard shales and limestones. It is particularly effective in sticky formations where balling problems are encountered. Three jets with replaceable nozzles continuously clean the tool's cutting structure, clearing debris buildup and increasing penetration.
Fixed Diameter Hole Openers are used in the following conditions:
When drilling of a big hole is not possible because of rig capacity.
When a satisfied penetration rate is not obtained when drilling a big hole, it is used after drilling is completed with a smaller bit.
When the hole direction must be controlled.

Nov 14 , 2022API Lifting Sub, Saver Sub, Straight Sub, Reduced Section Sub, Rotary Sub
A lift Sub enables safe and efficient handling of straight OD tubulars such as drill collars, shock tools, jars, directional equipment and other tools by using the drill pipe elevators. -
Nov 10 , 2022drilling jar
We designed every aspect of this double-acting hydraulic jar to withstand the rigors and long hours of challenging applications. Featuring an extra-long stroke length for exceptional impact and impulse forces during jarring operations, the Double-Acting Fully Hydraulic Drilling Jar offers infinitely variable trip loads up to the maximum rating of the tool. Only a minimal load is required in both the up and down jarring directions, which is crucial in directional, horizontal, and extended-reach wellbores. This makes the jar an ideal solution for modern drilling operations. -
Nov 08 , 2022API Oilfield Downhole Adjustable Motor for Directional Drilling
Tianhe downhole adjustable motor offers downhole adjustment of the motor bend setting, saving time and money by eliminating trips and optimizing critical drilling parameters. Adjusting the motor bend setting while downhole improves hole quality and increases rate of penetration throughout all sections of the well. SelectShift improves rate of penetration drilling by increasing the rotary/bit revolutions per minute (rpm) in the straight position, extending well reach and reducing side-loading of the bit. This design builds off motor technology, providing industry-leading torque output capability, 100% flow to the drill bit, and reduced bit-to-bend length.
