Pipe inspection maintenance and fee determination method

Abstract

The invention relates to a repair, maintenance and cost estimation method for pipes among producing facilities and devices of oil and gas fields. The invention mainly comprises following steps: (1) carrying out normal inspecting and comprehensive inspecting for a pipe in a fixed period; (2) carrying out quality evaluation for each inspecting result respectively in accordance with relevant pipe quality standards; (3) repairing the pipe and estimating repair cost in accordance with quality evaluation results of the pipe, and the estimated cost can be a reference and standard of pipe maintenance cost investment to solve the problems of insufficient investment or over investment; and (4) testing and accepting the repair results, checking if the repair quality meets pipe quality requirements and if the pipe can be put into normal use. Beneficial effects of the invention are: through timely normal inspection and comprehensive inspection of a pipe, eliminating fault risks of the pipe, decreasing possibility of accidents, prolonging service life of the pipe, increasing operation effects and profits of the pipe, and prohibiting negative influence to production of an enterprise due to accidents of the pipe and environment pollution.

Description

1. Technical field: [0001] The invention relates to a method for inspection and maintenance of oil and gas field production facilities and equipment, in particular to a method for inspection and maintenance of pipelines and cost calculation. 2. Background technology: [0002] Oil and gas field production facilities and equipment are the basis of oil and gas field production. Like any factory, its facilities and equipment also experience the whole process from being built and put into production to gradually wearing, corroding, damaging and scrapping. In the life cycle of facilities and equipment, maintenance and renewal should also follow certain rules like other industries. Due to the complexity and particularity of the facilities and equipment of oilfield enterprises, there has been no systematic summary study on the maintenance and update rules of oil and gas field production facilities and equipment for many years inside and outside the industry. Oil and gas field facil...
