Abstract:
Lei-11 reservoir of Moxi gas field in Chuanzhong has entered in the mid-late period of field development , with the problems of uneven distribution of reserves and pressure. In order to make clear the distribution characteristics of remaining reserves , to produce low permeability reserves in the west , to ensure reasonable deployment of horizontal wells and drilling rate , and enhance the ultimate recovery , the research on reservoir fine description , reservoir and physical properties distribution in 3D space must be carried out.On the basis of comprehensive study of fine geology , by the use of Petrel software , 3D fine structural model and property model have been established.Through parameter distribution and reserves calculation analysis before and after the simulation , the effect on reservoir horizontal well drilling rate and production relations has been analyzed and the model reliability has been verified , which provides guidance for gas reservoir analysis and evaluation.
