Real-time plugging device for undersea oil-leaking pipelines

Abstract

The invention aims to provide a real-time plugging device for undersea oil-leaking pipelines. The device is characterized by including a central rod, two guide wheel mechanisms, expansion mechanisms, guide pillars, a clamp basal body, hydraulic cylinders, hydraulic motors and two screw rods, wherein a central block and a top hydraulic cylinder are mounted on the central rod, the central rod is connected with the guide pillars and a first hydraulic cylinder through the central block, the central rod is sleeved by both of the guide wheel mechanisms, the expansion mechanisms are mounted on the central rod and located between the two guide wheel mechanisms, the guide pillars are mounted on the clamp basal body, the two screw rods are also mounted on the clamp basal body, a second hydraulic cylinder is mounted on a first screw rod, and the hydraulic motors are respectively mounted on the two screw rods. The real-time plugging device for undersea oil leakage pipelines provided by the invention achieves underwater unmanned operation, and can plug an oil-leaking undersea petroleum pipeline in a real time manner under the high pressure environment as deep as 1,500m underwater.

Description

technical field [0001] The invention relates to an automatic equipment for pipeline plugging and maintenance operations. Background technique [0002] In the 21st century, with the gradual reduction or even exhaustion of land and offshore oil and gas resources, in order to meet the growing energy demand, the world's advanced countries have focused on the development of oil and gas resources in the deep sea. About 70% of the total reserves of oil and gas resources on the earth are stored in the ocean. The average ocean depth is 3730m, and the sea area with a sea depth of 3000m-6000m accounts for 73.83% of the total ocean area. The 2002 World Petroleum Congress divided the water depth of marine exploration and development into conventional water depth within 400m, deep water between 400 and 1500m, and ultra-deep water above 1500m. At present, more than 80% of the world's proven offshore oil reserves are in water depths below 500m, which indicates that a large amount of oil a...

Problems solved by technology

[0005] Submarine pipeline maintenance is a complex and huge project, initially relying on divers to enter the water to check and implement operations. Since the 1970s, Britain, the United States and other countries have begun to develop various underwater pipeline maintenance devices, which have become mature. Compared with foreign countries Compared with my country, there is still a big gap in technology and equipment. my country has no equipment and devices that can implement underwater pipeline maintenance operations. Almost all underwater pipeline maintenance work is entrusted to foreign engineering companies, and maintenance costs are expensive.
