Description

Wireless self-orienting hydraulic slope guiding device

Technical Field

The invention belongs to well repairing tools, and particularly relates to a wireless self-orienting hydraulic slope guide.

Background

The existing hydraulic slope guider is composed of a hollow joint with a through hole inside, a feeder connected to the outlet of the joint, slope guider fixed on the feeder, and a setting device fixedly connected to the lower end of the slope guider.

Since most sidetrack wells require orientation, for the sidetrack wells requiring orientation, the whipstock must be fitted with a locating joint on the hollow joint before being run downhole, with the aid of which joint and gyroscopes the orientation of the whipstock ramp in the well is determined. The positioning joint comprises a joint main body used for connecting a drilling tool and a milling cone, a hollow piston body coaxially nested in the joint main body, positioning keys inserted into the piston body along the radial direction, two groups of sealing rings arranged on the hollow piston body, two fixing bolts vertically distributed on the joint main body and used for fixing the piston body, and a special sleeve used for adjusting the angle of the piston body.

During operation, the positioning joint is required to be connected to the slope guide and screwed by manpower, then the angle of the piston body is adjusted by using the special sleeve to enable the positioning key to be opposite to the central line of the slope iron of the slope guide, and then the fixing bolt is screwed to enable the piston body to be fixed in the joint main body so as to fix the positioning key; in addition, before the slope guide goes into the well, a hydraulic tong is used for stressing and screwing the slope guide and the positioning joint at the well mouth, so that the relative position of the positioning key and the slope of the slope guide is changed, correction is needed, the operation cost is increased, and the operation efficiency is reduced.

In order to solve the problems, the utility model with the publication number of CN206845096U discloses a self-orienting hydraulic solid deflector, which comprises a hollow joint, a tubular feeder, a deflector and a setting anchoring device which are connected in sequence, wherein a catheter for communicating the inner hole of the feeder with the inner cavity of the setting anchoring device is arranged in the deflector, a positioning key is arranged on the joint along the radial direction, and the positioning key protrudes out of the inner wall of the joint and is aligned with the inclined plane central line of the deflector; the locating key is matched with a key groove on the gyroscope used for determining the inclined plane direction of the inclined iron of the slope guider. After the inclinometer is put into the well in place, the gyroscope under the logging truck can be directly used for orientation without using a positioning joint, so that the materials are saved, the operation cost is reduced, and the operation efficiency is improved. However, since the gyroscope is used for wired logging, a special logging truck is required to be used for pulling up and down, the logging preparation and operation time is long, and much inconvenience is brought to sidetracking construction.

With the progress of the technology, wireless logging, i.e. logging while drilling, is becoming more and more perfect, wired logging systems are gradually replaced by wireless logging systems such as MWD and LWD, and wireless logging systems need to circulate drilling fluid to transmit logging parameters to the ground, so that the precondition for using a wireless logging system to orient a whipstock is that the drilling fluid must be circulated.

At present, two hydraulic fixed type slope guides are commonly used at home and abroad: one is a slope guider with a preset setting ball, which cannot circulate drilling fluid, such as the self-orienting hydraulic solid slope guider, and once the slope guider circulates the drilling fluid, the slope guider starts setting, so that the slope guider cannot be oriented by a wireless logging system; the other type is a slope guiding device of a back-throwing seat sealing ball, drilling fluid can be circulated, but the slope guiding device can be set only by throwing the seat sealing ball, if a wireless logging instrument is placed in a drilling tool, the seat sealing ball cannot be put in place, and the slope guiding device cannot be set. Due to the structural problems of the existing hydraulic fixed-type deflector, the application of the wireless logging instrument in the orientation of the hydraulic deflector is limited.
