Abstract

The invention relates to an impactor, in particular to a hydraulic impactor for drilling. The hydraulic impactor comprises an upper connector, a lower connector and a mandrel. Part of the lower connector extends into the upper connector. One end of the lower connector, extending into the upper connector, is provided with a spring. A cavity forms between the upper connector and the lower connector. The mandrel penetrates the lower connector and extends into the cavity. The upper connector is provided with a through hole. The hydraulic impactor is simple in structure and well practical.

Description

A kind of hydraulic impacter
Technical field
The present invention relates to a kind of impactor, particularly a kind of hydraulic impactor for well drilling.
Background technology
Along with the continuous increase of the oil/gas drilling degree of depth, difficulty and the cost of drilling well are doubled and redoubled, and the difficult problem that the poor hard formation of geological condition creeps into becomes increasingly conspicuous, and drilling efficiency is day by day low, have had a strong impact on job schedule and the cost of production of drillng operation.
Summary of the invention
The present invention proposes the good hydraulic impactor for well drilling of a kind of power performance.
A kind of hydraulic impacter of the present invention, comprise top connection, lower contact and mandrel, some stretches into top connection inside lower contact, one end that top connection inside is stretched in lower contact is provided with spring, between top connection and lower contact, be provided with cavity, mandrel, through lower contact, stretches in cavity, and top connection is provided with perforation.
A kind of hydraulic impacter of the present invention, simple in structure, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-top connection; 2-lower contact; 3-mandrel.
The specific embodiment
A kind of hydraulic impacter of the present invention, comprise top connection 1, lower contact 2 and mandrel 3, lower contact 2 has one to stretch into top connection 1 inside, one end that top connection 1 inside is stretched in lower contact 2 is provided with spring, between top connection 1 and lower contact 2, be provided with cavity, mandrel 3, through lower contact 2, stretches in cavity, and top connection 1 is provided with perforation.During use, body lower contact 2 is connected to high-voltage tube, liquid through high-voltage tube flows into rapidly in the cavity of lower contact 2 by mandrel 3, because the maximum cross-section area of the perforation of top connection 1 is less than the smallest cross-section area of cavity, therefore liquid forms liquid stream rapidly in perforation, has strengthened the impact force of impactor.
