Definitions
- all of the composite sleeves have the same inner diameter. This structure allows the number of composite sliding sleeves to be unrestricted, enabling unscheduled staged fracturing.
- a beveled guiding structure is provided at the upper and lower ends of each of the teeth to guide the corresponding The teeth form a fit or disengagement.
- the beveled guiding structure enables the corresponding toothed members to be fitted or disengaged by means of "squeeze” and “squeeze", which facilitates the opening or closing operation of the composite sliding sleeve.
- the sliding sleeve fracturing assembly further includes a second closing tool for closing the composite sliding sleeve, comprising a central pull rod and a sixth toothed member coupled to the central pull rod, the second closing tool being insertable
- the inner cylinder or the cylindrical body of the opening tool enables the sixth toothed member to cooperate with the first toothed member of the inner cylinder or the third toothed member of the opening tool, thereby being capable of lifting the second closing tool
- the inner cylinder is moved up to recap the blast hole to close the fracturing passage.
- the central body of the drive tool comprises a through hollow structure having different cross-sectional dimensions, a rolling mechanism is disposed in a downstream portion of the hollow structure, and the rolling mechanism is not capable of a larger cross-section from the hollow structure.
- the downstream part is detached, in particular, it cannot enter the upstream part of the smaller section.
- each second closing tool can only close one composite sliding sleeve. Thereby, it is possible to realize the switching of any composite sliding sleeve of a horizontal well, a vertical well, etc., to achieve sectional fracturing.
- the composite sliding sleeve, the opening tool, the first closing tool or the second closing tool and the joining and separating between the driving tools in the second aspect of the invention can be realized by automatically engaging and separating the respective tooth members by the elastic action, Make the operation more convenient. Since the inner diameters of all the composite sliding sleeves are the same, the number of the composite sliding sleeves of the present invention is not limited, and an unrestricted number of staged fracturing can be realized. After the opening tool is removed, the all-pass in the casing or tubing string can be realized, which overcomes the disadvantages of conventional fracturing, which affects the production of the casing or the tubing string due to the start of the ball staying in the casing or the tubing string.
- Figure la is a schematic view of a composite sliding sleeve of a sliding sleeve fracturing assembly in accordance with a first aspect of the present invention
- Figure 18 is a schematic illustration of an open tool string of a sliding sleeve fracturing device in accordance with a second aspect of the present invention.
- the second toothing of the opening tool projects out of the body under the action of the spring of the third resilient means and the set screw.
- the second toothed part Before the first toothed member of the associated sliding sleeve assembly is engaged, it is not ejected due to the pressing of the inner cylinder of the other composite sliding sleeve.
- the second tooth of the opening tool will eject from the body of the opening tool and the first tooth of the sliding sleeve assembly under the action of the spring. The pieces are joined.
- At least one of the teeth and/or the side of the tooth groove has an angle of 90° or less than the bottom surface thereof, that is, a rectangular tooth or a hook tooth is formed, so that the toothed member can be stably joined together. It will not be disengaged due to excessive force on the toothed part.
