Description

Technical Field

[0001] This utility model relates to a blowout preventer skid for continuous tubing equipment, belonging to the technical field of oil and gas field production enhancement equipment. Background Technology

[0002] The injection head and blowout preventer (BOP) are core components of coiled tubing equipment. The injection head's main function is to continuously deliver coiled tubing downhole for drilling, logging, and workover operations, and to smoothly retrieve the coiled tubing after the operation is completed. The BOP is a key piece of equipment to ensure safe operation of coiled tubing, preventing blowout accidents and ensuring safe production. When users replace or upgrade coiled tubing equipment, they generally choose larger injection heads and BOPs, as well as longer BOPs. Larger specifications result in a significant increase in weight and size. If the traditional layout is still used, it will increase the wheelbase of the supporting trolley, making transportation difficult. Transporting the BOP and BOP separately will increase transportation costs. To solve this problem, it is necessary to transport the BOP and BOP together. Simultaneously, while ensuring convenient field use, a BOP skid for coiled tubing equipment has been invented for transporting, storing, and repairing BOPs and BOPs. This skid also allows for quick connection of the BOP. In vehicle-mounted coiled tubing systems, the injection head and blowout preventer (BOP) are transported with the vehicle. During operation, connecting the BOP, especially the BOP pipe, requires unloading it from the vehicle, reversing its horizontal orientation, and then installing it, which is very inconvenient. This method of placing the BOP and BOP pipe vertically significantly saves on-site work time and improves work efficiency. Furthermore, after installing the BOP and BOP, personnel only have basic personal protective equipment such as safety helmets when installing wellhead tools, which does not provide sufficient safety protection. This BOP skid can be placed entirely at the wellhead, providing comprehensive protection for personnel installing wellhead tools. Utility Model Content

[0003] The purpose of this invention is to provide a blowout preventer (BOP) skid for coiled tubing equipment. The BOP skid is equipped with a BOP operating platform, allowing for BOP installation. The BOP is placed upright on the skid for direct connection. An adjustable cover is provided above the operating platform for safe and convenient installation. After operation, the BOP and BOP are returned to their original positions on the skid. The skid features a liftable frame, allowing for the lowering of wellhead tools such as screw motors, which can be operated from within the liftable frame. The height of the liftable frame is adjustable. A ladder is installed on the skid frame, allowing personnel to access the liftable frame for operation, significantly increasing personnel safety. This ladder is foldable, providing space for the BOP assembly and reducing the overall skid's transport dimensions, thus solving the problems existing in the prior art.
