ABSTRACT

Due to the formation of corrosion products, natural gas liquids and gas hydrates in long distance pipelines, timely and effective pigging operations are necessary to improve the gas transmission efficiency, reduce pressure loss, as well as guarantee the safe operation of gas wells, pipelines and networks. Gas transmission efficiency is a parameter to reflect the working condition and cleanliness of pipelines, which is calculated by the division of actual gas transmission volume and theoretical gas transmission volume. In consideration of the characteristics of long distance gas pipelines, a calculation model of gas transmission efficiency is presented in this paper. A threshold value of 90% is used to measure the running state of pipelines, so as to determine whether a pigging operation should be conducted. The influence factors are analyzed. Suggestions on the operation strategy of long distance gas pipelines are stated.
