Well bottom-hole flowing pressure evaluation method in 48 Block of S Gas field

Gas well bottom-hole flowing pressure is an important parameter in gas reservoir geological research and evaluation, reserves calculation, evaluation of capacity calculation and dynamic analysis. So, get accurate bottom-hole flowing pressure has significant importance to the production. Through the production analysis of 48 block in the S gas field, liquid bottom-hole flowing pressure calculating method of the production block were studied. The density of liquid correction iterative method and measured pressure combined were determined to evaluate the bottom-hole pressure for the gas well development and production.
