Mechanical perforator or mechanical tubing is a device that is non-explosive. These tubing perforator punches is designed to single hole perforate standard tubing. The main work functionality of the perforator is that it has an upward jarring action that will activate the perforator.
Mechanical perforator is such a device has a mechanism that also allows greater well depth and also higher BHP. It has also got higher amount of BHT. Visit the page Best Mechanical Perforator available.
The working or running process of a mechanical perforator is described below:-
First the perforator has to be assembled with the help of pins. This process will be lot more easily to do if you get assistance of the sharp knife. Also after every turn the knife has to be sharpened.
In the next step there is a need of a gauge. You have to make a gauge ring in order to run below the perforating depth that is needed. This is done to make sure that the tubing is free enough from any kind of obstructions.
Then there is the process which involves running of collar stop to the favourable depth that is needed for the procedure of perforation. This is an important step because on this step those factors that the perforator will be sheared against.
Then there is the need for attaching the perforator to a wire line tool string. After this the process allows the run of the perforator to the stop run of the previous process.
Then the process involves the jar down system with enough force to the shear so that the knife will be released from the running position to the cutting position.
Then the process involves the jar down system with enough force to the shear so that the knife will be released from the running position to the cutting position. This process should be executed with utmost care. If the perforator is running on heavy oil then it will better to allow time for parts to position because no doubt they will be slow as they will be moving in the heavy oil.
Then the process involves pulling up of the tool string that will force the knife to catch on the wall that is concerned with tubing. This will do the job of cutting the perforation. In case when the pool does not immediately catch then there will be the case when it will skid up the tubing. If such thing happens then it is wise to set it back down to the stop. Once you have done this you can try again. If you continue dragging the knife up the joint it will happen that the knife will become dull. It will become more dull it is reaches a collar. The knife is then catches to the tubing wall of the jar upwards till the perforator body is pulled past the knife and then the hole is created. When you are resetting the jar you should pay attention minutely and the knife should not jar down when the jar is resetting. If you apply too much force then the perforator knife can be removed from the cut.
