Abstract

The invention relates to a horizontal boring device used for a set-point deep-penetrating of an oil layer of an oil-water well, which mainly solves the problems of the existing two perforating devices that a ground investment is large; the equipment structure is complicated; a pressing belt is formed near a well and bushings are damaged. The invention is characterized in that the device consists of a measure-control system (I), a stepping system (II), a power system (III), a boring drill system (IV), an anchoring system (V) and a circulation system (VI), and each system also comprises a plurality of parts. The device adopts an electromechanical integration design and a power cable, and a computer on ground is used for a timely inspection and control to the horizontal boring device underground, and a horizontal hole which has a large depth, a large aperture and no pressing belt can be drilled on bushings, concrete rings and storing layers. With the invention, the pressing belt caused by the traditional perforating device can be eliminated, and the invention has the advantages that the control is easy and the bushings cannot be damaged.

Description

Technical field: [0001] The invention relates to the technical field of oil production engineering in oil fields, and belongs to a fixed-point deep-penetrating horizontal drilling device for an oil-water well oil layer. Background technique: [0002] At present, the submerged fixed-point abrasive perforating equipment used in oil fields includes pump trucks, sand mixing trucks, irrigation trucks and downhole perforating equipment. The cost of this set of equipment is relatively high, and the perforation depth is greatly affected by the confining pressure. The pipe has a large degree of damage; the hydraulic deep-penetrating jet perforation technology is a perforation technology developed in recent years for oilfield stimulation, and it is also a production stimulation technology for oilfield applications, but the hydraulic deep-penetration jet The structure of the perforating equipment is also relatively complex, mainly including surface pump trucks, tank trucks and downhole...
