In application of the formation test data of well drilling and well completion collected from some early exploration wells

node analysis was made so as to draw a reasonable plan for the production forecast and production regulation. On the basis of the node analysis principle and early well test data

the present article suggests the basic equations to draw input and output curves and provides friction-damping coefficient for new prospect areas. The above mentioned method has been proved to be very useful in certain oil fields' production of west China for the past five years.
