Reliability Statistics of Operational Data from Gas Pipe Networks

The paper introduces the distribution models of accidents and maintenance times for the units constituting natural gas pipe networks system, the basic method and procedure in the statistics of operational data from gas pipe networks, and according to the operation records in two years past from the two gas wells in the pilot testing area of middle ShanGanNing Basin gas fields, presents the distributions of accidents and maintenance times, obtains statistics on the characteristic parameters of reliability for the wells.
