Novel hydraulic oscillator for downhole operations in oil field

Abstract

The invention discloses a novel hydraulic oscillator for downhole operations in an oil field. The hydraulic oscillator comprises a sleeve, wherein the bottom of the sleeve is connected with a containing cylinder, the containing cylinder is a round table shape, a movable terminal is arranged in the sleeve, and the bottom of the movable terminal is provided with a group of arc-shape through groovesaround the circumference; two ends of the arc-shape through grooves are provided with openings, the arc-shape through grooves penetrate through opening elastic sleeves, two ends of the opening elasticsleeves are connected with clamping plates, the opening elastic sleeves penetrate through springs, the springs are connected with oscillating balls, and the clamping plates are fixed through bolts; the springs are sleeved with soft sleeves, the tops of the soft sleeves are provided with a group of top connecting holes around the circumference, the top connecting holes are connected with top metalwires, the top metal wires are bound to the tops of the springs, the bottoms of the soft sleeves are provided with a group of bottom connecting holes around the circumference, the bottom connecting holes are connected with bottom metal wires, and the bottom metal wires are bound to the bottoms of the springs. The hydraulic oscillator is used for downhole operations in an oil field.

Description

Technical field: [0001] The invention relates to a novel oil field downhole operation hydraulic oscillator. Background technique: [0002] Hydraulic oscillators are needed for downhole operations in oil fields. Some of the existing hydraulic oscillators have insufficient vibration force, which cannot meet the needs, and the use effect is not ideal. Invention content: [0003] The purpose of the present invention is to provide a novel hydraulic oscillator for downhole operation in an oil field, which can meet the demand and whose oscillation force can be adjusted according to the demand. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A new type of hydraulic oscillator for downhole operation in oilfields, comprising: a sleeve, the bottom of which is connected to a storage tube, the storage tube is in the shape of a frustum of a cone, movable terminals are arranged in the sleeve, and the The bottom of the movable terminal has a set of arc-...
