Development and Improvement of Calculation Method for Productivity Implementation Rate and Its Application in Daqing Oilfield
The productivity implementation rate is an important indicator in the preparation of reservoir engineering scheme and development planning scheme in the process of crude oil production capacity construction.The geological conditions and ground conditions of the production capacity construction object of Daqing Oilfield continue to deteriorate,and the traditional calculation method for the productivity implementation rate is insufficient,which is difficult to meet the demand of indicator prediction in complex and changeable situations.By analyzing the changes of classified capacity indicators in recent years and combining with the actual needs of crude oil development planning,the connotation of productivity implementation rate is expanded,and the concepts and calculation methods of planned productivity implementation rate and actual productivity implementation rate are creatively put forward.The results indicate that in the planning stage at the beginning of the year and the production allocation stage at the end of the year,the indicators of planned productivity implementation rate and actual productivity implementation rate are perspectively applied to predict the second year oil production of new production capacity,with the prediction accuracy rate of over 95%,which effectively guides the prediction of oil production of new production capacity in the second year.The research results provide important references for the optimization of annual production capacity construction planning,and provide important basis for accurate estimation of annual and medium to longterm production.
