Abstract

The invention discloses an automatic braking and accurate control type slurry pulser for petroleum drilling. The automatic braking and accurate control type slurry pulser for petroleum drilling comprises an iron core and a driving shaft. The iron core and the driving shaft are coaxially arranged. The driving shaft is located in the iron core. An outer hollow column and an inner hollow column are arranged between the iron core and the driving shaft and fixedly connected with the inner side wall of the iron core and the outer side wall of the driving shaft correspondingly. Multiple permanent magnets are symmetrically embedded into the side wall of the inner hollow column, multiple installation grooves are symmetrically formed in the outer hollow column, and a solenoid coil and a braking mechanism are fixedly installed in each installation groove. The automatic braking and accurate control type slurry pulser for petroleum drilling is novel in structure and convenient and fast to overhauland replace. The stable tension can be provided for the driving shaft through the devices such as the solenoid coils and the permanent magnets. Braking wheels enable the driving shaft to be rapidly braked, the springback problem cannot appear, and therefore the stroke accuracy of the slurry pulser is higher.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to an automatic braking and precise control type mud pulser for petroleum drilling. Background technique [0002] During oil field survey and production, multiple drilling tasks are required to obtain various information of the target oil field. With the development of the petroleum industry and the advancement of science and technology, there are more and more auxiliary drilling equipment. The mud pulser is used as Representatives of drilling equipment have also been more and more widely used. There are three main types of mud pulsers: positive pulse mud generators, negative pulse mud generators and continuous wave mud pulse generators, because continuous wave mud pulse generators are in feedback The data is more reliable and fast, therefore, in the oil drilling operation, the continuous wave mud pulser is often used. [0003] The existing continuous wave mud pulser mainly relie...
