ادوات تحديد النقطه الحره اثناء استك-Free Point Indicator Tool

Electric wireline service companies run instruments on captain lines inside the wedged drill pipe or tubing and are suitable to directly determine the wedged point( check also stuck point computations) of the pipe. The instruments called free point index tools are largely sensitive electronic bias that measure both stretch and necklace movement in a drill string. This information is transmitted through the electric captain string to a face panel in the control unit where the driver interprets the data.

Free Point Indicator Tool

The introductory free- point instrument consists of a mandrel which encompasses a strain hand or microcell. At the top and bottom of the instrument are disunion springs, disunion blocks, or attractions, which hold the tool strictly in the pipe.


*When an upward pull or necklace is applied at the face, the pipe above the wedged point stretches or twists.
*The change in the current passing through the instrument is measured by the microcell and transmitted to the face for interpretation.
*When the instrument is run in wedged pipe, there's no movement of the pipe, thus there's no pressure or necklace transmitted to the instrument.
*In turn, the hand at the face shows no change in its reading.
Free- point pointers are constantly run with collar locators and in combination with string shots, chemical knives, and spurt knives( check also Mechanical Drill Pipe Cutter). This combination run saves precious carriage time, and it'll also maintain a nonstop sequence in measuring so that there's lower chance of a misrun in cutting or backing- off operations.


Since fishing operations generally begin as soon as the pipe is parted following the free- point determination, it's a good practice to have the fishing tool administrator or driver on the position during the free- point and back- out or cutting operations. constantly there are suggestions that can be made to ameliorate the fishing situation when the fishing driver is present to observe the free- point and parting operations.
