LIQUIDATION OF STUCK PIPE DURING WELL DRILLING

 

Annotation. This article considers one of the most widespread problems arising in the course of well drilling: sticking of drill pipe and casing, which requires significant expenditures for their elimination. It has been revealed that the reasons of their origin can be differential pressure, jamming of bit in non-expanded and narrowed sections of wells, collapse of unstable rocks, wedging of the tool due to penetration of foreign objects into the well, accumulation of cuttings if flushing is not good enough. In order to solve this problem, it is suggested to use hydraulic impact devices (oil jars). Application of such a device as an elimination of sticking while drilling is caused by proved reliable technical characteristics and resistance to abrasive wear.

Keywords: stuck drill pipe and casing, elimination of stuck pipe, hydraulic impact mechanism, borehole, impact momentum.
