Abstract

The invention provides a method, a device and a system for monitoring the underground working state of a torsion impacter, and relates to the technical field of oil-gas exploration, the monitoring method comprises the following steps: step 1, measuring engineering parameters of the torsion impacter underground and storing the engineering parameters; 2, analyzing the engineering parameters underground to obtain the analysis data, and judging whether the working state of the torsion impacter is normal or not according to the analysis data to obtain a judgment result; and step 3, transmitting the judgment result to the ground. According to the method, the device and the system for monitoring the underground working state of the torsion impacter, the working state of the torsion impacter can be quickly obtained.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a method, device and system for monitoring the downhole working state of a torsion impactor. Background technique [0002] With the continuous development of oil drilling technology, a large number of deep wells and ultra-deep wells have increased, and the possibility of encountering "three high formations" (high rock hardness, high rock drillability extreme value, and high abrasiveness) is increasing. Stick-slip vibration is prone to occur when conventional drilling methods are used in the above-mentioned "three-high formation" drilling process, which seriously restricts the improvement of ROP in deep hard formations. Through in-depth research on the suppression method of stick-slip vibration, it is found that the torsional impact drilling technology is one of the effective methods to suppress the stick-slip of the drill bit. This technology relies on the develop...

Problems solved by technology

However, there are many types of torsional impactors, and the quality is also uneven. Different types of torsional impactors have different effects in well sections of different depths and under different lithological conditions.

If the working status of the torsional impactor cannot be monitored, it is impossible to accurately judge whether the torsional impactor is working normally; at the same time, the working efficiency of the torsional impactor cannot be directly expressed through downhole data

[0004] In the prior art, there are limited methods for monitoring the downhole working status of the torsion impactor, and drilling personnel are often unable to accurately determine whether the torsion impactor is working normally, which greatly limits the further development of the torsion impactor
