Description

Technical Field

[0001] The present invention relates to the field of downhole device maintenance, and in particular to a hydraulic shaping instrument capable of real-time monitoring and a use method thereof. Background Art

[0002] Due to the combined effects of geological, engineering, and corrosion factors, casing deformation can occur during oil and gas field development. Currently, the main methods for repairing casing deformation include impact-type shapers and rolling-type shapers. Impact-type shapers can generally only repair single-point deformation, requiring multiple trips for casing with significant deformation and causing significant damage to the casing. Rolling-type shapers can repair long sections at multiple points. Patent application number 03266194.0 discloses a "casing shaper" consisting of a cone and a threaded drill pipe connection end. The cone is characterized by a front positive cone and a middle negative cone, a through hole within the cone, a guide cone and rounded corners at the front edge of the cone, and blind holes along one or more spiral lines on the surface of the cone, each containing a spherical body. This utility model has the advantage of repairing a large amount of casing in one trip, reducing the number of trips, but it cannot achieve complete casing repair in a single trip. Patent application number 201320110191.8 describes a combined ball expander. Under the action of upper hydraulic thrust or upper downward force, the variable-diameter ball expander squeezes and expands the deformed casing. After it passes through the deformation section, the shaping string is lowered, and the ball straightener straightens the bent portion of the deformation section. After the bent and deformed section is fully straightened, shaping can continue on to the next sleeve section. This type of straightener can shape longer sections, but after the straightener is completed, the string may retract, causing resistance when running a new tool. At this time, the shaping tool must be re-run for shaping, but the shaping effect cannot be monitored in real time, making many processes time-consuming and labor-intensive.

[0003] When a cable-run caliper is used for measurement in a long deviated well, the caliper's own gravity can cause it to become eccentric within the wellbore, misaligning the caliper's axis with the wellbore's axis. This can cause the measured value to be less than the wellbore diameter. Application No. 201220254382.7, titled "40-Arm Caliper," discloses a caliper comprising a central tube, a main control panel, an upper stabilizer, multiple measuring arms, a displacement sensor, and a guide cone. This non-contact caliper can mitigate the misalignment issue to some extent, but it cannot fundamentally resolve the problem. The caliper or other testing instrument used in the present invention is run through a rigid tubing string into the desired location, effectively resolving the measurement eccentricity issue.
