Gas transportation pipeline lubricating oil accumulation positioning detecting and pump drainage system

Abstract

The invention belongs to the field of natural gas pipeline safety maintenance, and relates to a gas transportation pipeline lubricating oil accumulation positioning detecting and pump drainage systemwhich is targeted to detection of sedimentation and adhesion positions and accumulated amount as well as pumping treatment of lubricating oil in a natural gas pipeline. The system is characterized inthat, the system is composed of a pipeline robot and a rear end controlling system; the rear end controlling system sets operation parameters, controls a placing and recovery system and a gas liquid separation storage device, guides and controls entry and exit of the robot, and conducts post treatment of oil gas drained. The pipeline robot is controlled by a front end controlling system, is provided with a sedimentation detecting module, a three-dimensional space detecting module, a data storage module, a power module and a pump drainage module, independently detects and processes the lubricating oil in the pipeline, and at the same time sends back data. Compared with the prior art, the system has the following advantages: detection and treatment can be conducted without suspending production, one-time detection of spatial status of the pipeline, accumulation status of the lubricating oil and the accumulation position can be realized, one-time treatment of accumulated lubricating oil can be realized, and the system can be used for detecting deformation and defects of the pipeline.

Description

technical field [0001] The invention belongs to the field of safety maintenance of natural gas pipelines, and relates to a detection and pumping treatment system for the deposition, attachment position and cumulative amount of lubricating oil in natural gas pipelines. Background technique [0002] In recent years, in order to meet the needs, the scale of my country's oil and gas pipeline network has continued to expand, and the level of pipeline construction and management has been greatly improved. According to the "Medium and Long-Term Oil and Gas Pipeline Network Planning", the scale of the national long-distance oil and gas pipeline network will reach 169,000 km by 2020; by 2025, the scale of the pipeline network will reach 240,000 km. 131,400 km, including about 72,600 km of natural gas pipelines, 30,900 km of crude oil pipelines, and 27,900 km of refined oil pipelines. [0003] With the implementation of the clean energy strategy, the consumption of natural gas in my ...

The first idea is the following two patents (application number: CN201610111812.2, CN201510386095.X), one is to reduce deposition by improving the liquid carrying capacity through the gas vortex effect, this scheme does not fundamentally reduce the liquid accumulation in natural gas, And it can only treat the water in the gas; the other is to remove the effusion by gas lift, which has a small processing capacity and is easy to leak and pollute the environment
