Econo Mill
The Econo mill is an effective tool for light duty milling jobs such as packers,bridge plug,and cement.This mill can be easily make-up and break-out with standard bit breakers.

Internal cutter is a down-hole mechanical cutting tool designed to cut casings,tubings and drill pipes.The main advantages are its simple structure,reliable performance and high cutting efficiency.In order not to cut the casing and tubing couplings,the cutter shall be kept away from these couplings during operation.Depending on drilling conditions,it can be used in conjunction with coupling locator to locate the position of the nearest coupling from the cutter.When the internal cutter is used with the releasing spear,it can cut and remove the cut tubing inone fishing operation.Alter natively,a separate fishing tool can be used to remove cut pieces.
Application Scenarios 1. Well Intervention and Workover When tubulars are stuck, damaged, or need to be removed during well maintenance, the cutter helps isolate and cut the problematic section to facilitate recovery or replacement. 2. Abandonment and Plugging Operations During well abandonment, it cuts casing or tubing to prepare for plug placement, ensuring proper well closure. 3. Emergency Pipe Recovery In cases where stuck pipes cannot be retrieved intact, the cutter severs the tubulars to retrieve upper sections and minimize operational delays.
Section mills are primarily used to milling sections in the casing (for side tracking,gravel packing) and perforation zones.XINRUIDE section mill is available in a variety of Casing sizes,ranging from 4 1/2" to 13 3/8".The blades are all dressed to enable simultaneously milling of the casing.The milling rate is usually limited by the ability of the fluid in removing the cuttings.
Heavy Weight Drill Pipe (HWDP) is an intermediate weight drill stem component which is used in conjunction with the drill pipes and drill collars. XINRUIDE HWDP is avalable in standard,spiral and non-magnetic designs.In some applications,heavy-weight drill pipes also can be used instead of the drill collars.
The oriented bent sub is a major power deflection tool having a fixed angle deviated from the low end thread of the bent sub to the axial line of drill stem.Under the application of oriented bent sub the power drill tool give the bit a constant lateral force to ensure that the bit can cut on the well wall laterally and further drill into a curved well trace.
