Description

Technical Field

[0001] This utility model belongs to the field of well workover operation technology, specifically, it relates to a quick-connect installation device for a well tree. Background Technology

[0002] The oilfield's security and fire protection center is primarily responsible for well control emergency response and rescue, quickly handling accidents and providing timely and strong support to ensure safe production in the oilfield. Wellhead cutting is a crucial part of well control emergency rescue and is typically carried out as follows: The tail end of the cutting support is connected to a fracturing truck, and water is pumped into the fracturing truck to increase pressure. Garlic sand from the fracturing truck is then transported to the cutting nozzle at the front of the cutting support via the cutting support's pipeline. The high-speed jet from the cutting nozzle cuts the wellhead. After cutting, one end of a steel wire rope is secured to the flange at the bottom of the Christmas tree, and the other end is connected to a crane. The Christmas tree is lifted and moved by the crane. Then, the crane is connected to another Christmas tree via a steel wire rope, and the Christmas tree is suspended and aligned for installation at the wellhead. However, during the installation of the Christmas tree, the crude oil ejected from the wellhead contains hydrogen sulfide and natural gas, which can easily ignite upon contact with sparks. If the Christmas tree is secured with a steel wire rope during installation, the flames could easily burn through the rope, posing a significant safety risk. Furthermore, using a steel wire rope to secure the Christmas tree results in low installation efficiency, severely impacting the rescue mission. Utility Model Content

The connecting plate 2 is used to connect with a quick-connect coupling of an operating mechanism (e.g., an excavator). A snap-fit ​​member 4 is disposed on the second side of the vertical plate 1. A guide opening 3 and a snap-fit ​​interface 5 communicating with the guide opening 3 and used to snap the oil production tree are disposed at the end of the snap-fit ​​member 4 away from the vertical plate 1. The guide opening 3 is configured as a flared opening. The snap-fit ​​interface 5 extends from the end of the guide opening 3 toward the direction close to the vertical plate 1.

[0022] The following is a brief description of the use of the quick-connect installation device 100 for wellheads described in this utility model. Before emergency repairs, the connecting plate 2 can be connected to the quick-connect coupling of the excavator. When it is necessary to install the wellhead, operate the excavator so that the guide port 3 of the quick-connect installation device 100 is aligned with the outer wall of the main channel of the wellhead. Continue operating the excavator to move the guide port 3 closer to the main channel of the wellhead, so that the outer wall of the main channel of the wellhead is engaged in the locking interface 5. Then, operate the excavator to lift the quick-connect installation device 100 to move the wellhead to the wellhead and install it in place.

[0023] According to this utility model, a vertical plate 1 and a connecting plate 2 disposed on the first side of the vertical plate 1 for connecting the operating mechanism are provided. A snap-fit ​​component 4 is provided on the second side of the vertical plate 1. At the end of the snap-fit ​​component 4 away from the vertical plate 1, a guide opening 3 and a snap-fit ​​interface 5 communicating with the guide opening 3 are provided. The guide opening 3 is constructed as a flared opening, and the snap-fit ​​interface 5 extends from the end of the guide opening 3 towards the direction closer to the vertical plate 1. During operation, the oil tree is guided through the guide opening 3 to the outer wall of the main channel of the oil tree, and then snapped onto the outer wall of the main channel of the oil tree through the snap-fit ​​interface 5. After being lifted, the oil tree is installed, avoiding the use of wire rope hoisting for installation, reducing safety risks. Simultaneously, the entire quick-connection and installation process is carried out continuously, improving installation efficiency and ensuring the smooth progress of the emergency rescue mission. Furthermore, during installation, if the oil tree slips along the snap-fit ​​interface 5, the upper surface of the snap-fit ​​component 4 can snap onto the upper channel of the oil tree, thereby preventing the oil tree from falling to the ground.

[0024] In one or more embodiments, the size of the card interface 5 is the same as the outer diameter of the main channel of the tree.
