Casing drilling equipment control method and device, electronic equipment and drilling system

Abstract

The invention provides a casing drilling equipment control method and device, electronic equipment and a drilling system, a drill bit is controlled to drill from an initial depth to a preset depth according to a preset drilling strategy, the drill bit is controlled to perform back reaming treatment on an oil well to obtain back reaming time, and the initial depth is the depth of the position where a casing shoe is located; the drifting equipment is controlled to be lowered from the initial depth to the preset depth according to the preset speed, so that drifting time is obtained; and according to the back reaming time and the drifting time, the casing pipe is controlled to be lowered in the oil well. According to the scheme, the problem of low efficiency caused by static observation of hole diameter reduction can be solved, the casing drilling time is shortened, and the casing drilling efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of oil and gas exploitation, in particular to a casing drilling equipment control method, device, electronic equipment and drilling system. Background technique

[0002] During the drilling process of the petroleum salt-gypsum layer, due to the characteristics of the salt-gypsum layer itself, the formed oil well will have the wellbore spalling, which will reduce the well diameter and affect the drilling efficiency. .

[0003] The existing casing drilling technology uses the drill bit to drill into the salt and gypsum layer to form an oil well. After static observation of the change of the well diameter, the casing set outside the drill bit is lowered to seal off the rock that has been peeled off the well wall and complete the solidification process. well.

[0004] However, in the prior art, it is necessary to repeatedly observe the reduction of the well diameter and control the drill bit to pass the well b...
