Embodiment Construction
[0023] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0024] Such as Figure 1 to Figure 3 As shown, this embodiment provides an adjustable-angle skewer guide cone joint, which includes a joint body 6 whose basic shape is a cylinder. The outer diameter of the joint body 6 is the same as the outer diameter of the skewer guide pipe 5. The size of the oblique guide tube 5 is not limited here.
[0025] The upper part of the joint body 6 is provided with a connecting thread 1, and the connecting thread 1 is a male thread for connecting with the female thread at the bottom of the recliner conduit 5.
[0026] The lower part of the joint body 6 is provided with a guide cone slideway 3, and the guide cone slideway 3 has a T-shaped cross-section matched with the base of the guide cone 8, so that the base of the gu...

The invention relates to whipstock connectors, and discloses an adjustable angle type whipstock guiding cone connector. A connecting thread is arranged at the upper portion of the connector body and used for being in threaded connection with the bottom of a whipstock guide pipe. A guiding cone sliding way extending in the radial direction from the axis position of the connector body is arranged at the lower portion of the connector body, and openings are formed in the bottom face and the side face of the connector body through the guiding cone sliding way. A guiding cone base is embedded in the guiding cone sliding way. After the guiding cone base slides in the guiding cone sliding way and the position is determined, wedge blocks with which the residual space of the guiding cone sliding way is filled are used for positioning. Angle adjusting installation holes evenly distributed in the radial direction are formed in the middle portion of the connector body, crow bars are inserted in the angle adjusting installation holes for adjusting the relative position of the thread connecting position of the connector body and the whipstock guide pipe, and accordingly the whipstock opening direction can be adjusted. According to the adjustable angle type whipstock guiding cone connector, guiding cone radial installation position adjustment and 360-degree free adjustment of the whipstock opening direction can be conducted at the same time, accordingly, efficient guiding cone installation is achieved, the installation process is simplified, and the machining cost is saved.
Description
technical field [0001] The invention relates to a skewer joint, in particular to a skewer guide cone joint capable of adjusting the angle. Background technique [0002] Offshore oil and gas fields developed in the early stage are gradually entering the middle and late stages of production. In order to achieve the goal of increasing and stabilizing production, the existing notch resources are usually used to drill adjustment wells and infill wells to make up for the deficit. However, the old offshore platforms generally have problems such as no slots available or no slots available. [0003] In China, the well slot reuse technologies on offshore platforms such as casing milling to open windows and hanging well slots are mainly used to realize the reuse of old well slots, but the economic efficiency still needs to be improved. With the application and popularization of high-efficiency underwater cutting technology such as water jet, the method of overall cutting recovery + ri...
