The Design Procedure Model Study of Gas Transmission Pipeline

On the basis of statistic data from American pipeline construction, the ratio of materials versus pipeline investment, the relation between gas-compressing-station's horsepower and station investment is founded by means of calculation. The calculating procedure used in estimating investment of gas transmission pipeline and counting operation cost item described in PetroChina's project economic evaluation method and parameters is made. The base of combined optimization algorithm is set up and the procedure design model is proposed.
