Downhole Tooling Private2 months ago - Automobiles - Bāli - 26 views
Downhole tooling refers to the tools used downhole during drilling operations. Downhole Tools include drill bits, air hammer systems, mud mixers, transmitter housings, adapters, and reamers. Downhole tooling is very important in a drilling operation as it can impact the overall productivity of the machine.
Since tooling is prone to wear and tear the cost of tooling should be taken into account while considering the overall cost of operation.
Downhole tooling is selected based on the production goals of a project, geology, obstacles and ground conditions. Right tooling selection is governed by selecting the right drill bits, selecting the right sonde housing, and the correct back reaming accessories. Good downhole tooling can also help manage drilling fluid better. Since downhole tooling is an attachment, there is a possibility of losing the tools downhole.
Tooling should be sturdy, well-fitting and optimized for the drilling operation. A tool that breaks downhole can end up increasing wait time and thereby cost of the operation.
The term ‘Mechanical Set Packer’ probably doesn’t mean much to those not in the concrete repair industry. But for those close to chemical grouting, this term certainly brings about thoughts of both form and function. Mechanical packers are also referred to as ports, or more simply, packers. But we would like to be very clear that a port is not a packer.
Packers also come in various types. Suppliers will market benefits of steel, brass, zinc, or aluminum. All things considered, Permanent Set Packers tend to be the most versatile packers as they are compatible with all chemical grout types, while the brass, aluminum, and zinc can exhibit signs of deterioration when using oxidizing agents such as the salt component in a polyacryate gel. However, some contractors insist that the breakdown is not as quick as marketed by suppliers, therefore utilizing brass and aluminum packers in these applications as well.
Each packer features an anti-return ball valve that is opened under pressure, allowing the passage of chemical grouts. Upon depressurizing, the ball valve will close, prohibiting the return flow of the injection resin out of the drill hole. This ball valve can be located on the top of the packer, in the base of the packer, or even freely-floating in the packer shaft to allow for maximum flow. There are pros and cons to each ball valve location depending on job site condition and application and finishing techniques.
Lastly, there are plastic alternatives commonly referred to as ‘bang-in’ or ‘hammer-in’. These Hydraulic Set Packer do not have the threaded metal shaft, but as they are driven into the drill hole, the same compression seal theory takes hold as the tapered edges become lodged into the drill hole sides. Another form of plastic ports is a plastic, surface-mounted version that is commonly used in epoxy injection and/or in the event that drilling into the substrate would be considered harmful or ill-advised.
Once drilling operations have been completed, it is important for drillers, engineers and geologists to determine whether to move on to the next phase: completion for production. Formation Test Tools ascertain if there are enough hydrocarbons to produce from a well, as well as provide important information to design the well completion and production facilities.Understanding what is happening thousands of feet beneath the surface must always require inferences, but between more robust and affordable Downhole Cleaning Tools and models that can turn data into deeper insights, it is becoming easier to picture downhole events at the surface.
