The technical scheme includes that the upper end of an upper barrel is in screwed connection with a screw drilling tool, the lower end of a lower barrel is in screwed connection with the drill bit, a lower thrust bearing is mounted on an excircle step of the lower barrel, a supporting seat, a spring, an upper supporting seat, an upper thrust bearing and a sealing cap are sequentially nested into the excircle of the lower barrel, the upper end of the lower barrel is in screwed connection with a transmission head, a transmission pin and the transmission head are integrally arranged on the lower portion of an inner cavity of the upper barrel, four upper supporting arms are hinged in four grooves of the upper supporting seat, four lower supporting arms are hinged in four grooves of the lower supporting seat, and four rollers, the upper supporting arms and the lower supporting arms are hinged together by using pin shafts. The pressing-type damping stabilizer is of a pure mechanical structure and is simple in structure and high in reliability; the pressing-type damping stabilizer works by applying drilling pressure, thereby being simple to operate, and vibration of the drill bit and the drill string can be reduced effectively.
Description
Technical field
The present invention relates to a kind of type pressure-actuating damping stabilizer of oil and gas industry drilling engineering.
Background technology
Drilling engineering is an excessive risk of oil and gas industry, the engineering of high investment.There will be the engineering problem of many complexity in drilling process, drill bit is exactly a ubiquitous problem in the vibrations in shaft bottom.Strenuous vibration huge the pressure of the drill will be born due to drill bit and carry out rotary motion at a high speed, so inevitably drill bit can occur in shaft bottom.Bit vibration can reduce the application life of drill bit greatly, also to drilling tool generation destruction to a certain degree.There is larger gap between the nearly brill stabilizer of current use and the borehole wall, this gap result in drill bit can produce certain vibration amplitude, even causes drill bit to wave, and well track produces skew.
Based on above-mentioned technical background, spy of the present invention provides a kind of type pressure-actuating damping stabilizer, makes up the deficiency of existing nearly brill stabilizer, overcomes the vibrations that in drilling process, bit location is harmful.
Summary of the invention
The object of the invention is: in order to reduce the vibrations of drill bit and drill string in drilling process, spy provides a kind of type pressure-actuating damping stabilizer.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of type pressure-actuating damping stabilizer, is made up of upper shell, driving head, trundle, capping, up-thrust bearing, upper support seat, upper support arm, roller, lower support arm, spring, lower support seat, lower thrust-bearing and lower shell; Its architectural feature is: upper shell upper end and helicoid hydraulic motor screwed connection, lower shell lower end and drill bit screwed connection; Lower shell cylindrical bottom arranges a step, and lower thrust-bearing is arranged on lower shell cylindrical step, and lower shell cylindrical is inserted in lower support seat, spring, upper support seat, up-thrust bearing and capping successively, and spring is in compressive state; Lower shell upper end and driving head screwed connection; Driving head excircle is semicircular groove to evenly arranging eight cross sections, groove closed at both ends; Upper shell lower end cylindrical is set to screw thread, and it is semicircular groove that upper shell inner chamber bottom circumference evenly arranges eight cross sections; Eight trundles are arranged in driving head cylindrical eight grooves, and trundle and driving head entirety insert upper shell inner chamber bottom; Upper shell lower end and the screwed connection of capping upper end; Upper support seat bottom circumference evenly arranges four grooves, and lower support seat top circumference evenly arranges four grooves; Four upper support arms are articulated with in upper support seat four grooves, and four lower support arms are articulated with in lower support seat four grooves; Four rolling, four upper support arms are together with four lower support arm hinge.
The invention has the beneficial effects as follows: (1) the present invention is pure frame for movement, and structure is simple, reliability is high; (2) the present invention carries out work by applying the pressure of the drill, simple to operate; (3) the present invention utilizes roller to be adjacent to the borehole wall, effectively can weaken the vibrations of drill bit and drill string; (4) the pressure of the drill of the present invention is larger, and damping effect is better.
