Problems solved by technology

Due to the complex composition of the residues in the abandoned pipeline, and the long disposal time and complex nature, it is very difficult to clean the crude oil pipeline until it is free of oil, wax and dirt at one time
At present, compared with foreign countries, there are few researches

Embodiment Construction

[0023] The cleaning process of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the harmless cleaning process of the abandoned crude oil pipeline of the present invention comprises the following steps:

[0025] In the first step, in order to ensure the smooth progress of the cleaning work, it is first necessary to detect and locate the abandoned pipeline 1 . The construction machinery and tools should be in place two days before the start of construction, excavate the operation pit at both ends of the cleaning pipeline, and level the site in the operation pit.

[0026] Install signal receivers 2 on the ground close to both ends of the abandoned pipeline to ensure that the passage of the pig is detected during cleaning;

[0027] The two ends of the abandoned crude oil pipeline are respectively connected to the pigging tube 3 and the ball receiving tube 4, and the tube 3 is connected...

Abstract

The invention discloses a waste crude oil pipe harmless cleaning process. A pipe cleaning train consisting of four sets of pipe cleaners, and special detergent liquid columns, compressed nitrogen gas columns and clean water liquid columns formed among the four sets of pipe cleaners slowly moves in a pipe to fully dip and thoroughly clean residues attached on the inner wall of the pipe. The process adopts a physical and chemical combined cleaning method to clean a waste crude oil pipe, can remotely monitor and intelligently adjust the traveling speeds of the pipe cleaners, accurately determines the dissolving time of detergent in the pipe to the residues, and guarantees the pipe cleaning effect; and the residues and the cleaning waste liquid in the pipe are respectively collected in a manner of not falling to the ground, so that the pollution is prevented from the source. The special detergent can guarantee efficient, quick and thorough dissolving of the firm residues in the waste crude oil pipe, is matched with clean water for cleaning to enable the waste pipe to achieve the effects of no wax, no oil stains and no scales in the pipe after cleaning, and can show natural color of metal.

Description

technical field [0001] The invention relates to a treatment technology for crude oil pipelines, in particular to a harmless cleaning process for abandoned crude oil pipelines. Background technique [0002] When the service life of the pipeline reaches the upper limit or the benefit of continuing to transport crude oil is far lower than the transportation cost and the pipeline has no other potential uses, the pipeline needs to be abandoned. Since the construction of the first crude oil pipeline in my country in 1958, the development of oil and gas pipelines has been changing with each passing day. 4 km. At present, due to the long running time and serious aging of many pipelines, accidents occur from time to time, and with the rapid development of China's economy, the environment through which the pipelines pass has also undergone tremendous changes, and some pipelines are gradually covered by living areas. Accidents will cause huge economic losses and have a greater social...
