Initial production capacity evaluation and its influencing factors analysis in complex fluvial KL oil field

In recent years,several complex fluvial deposit oilfields in southern Bohai has been put into production and the total production is consistent with development plan,while the single well productivity is quite different.In order to get a reasonable production capacity evaluation,by taking KL oil field group in southern Bohai Sea as an example,through comparison of the initial production and the ODP plan,the influence of specific productivity index,reservoir thickness,reservoir properties,time correction factor and interlayer interference factor to production evaluation was respectively analyzed.And therefore,the new correction methods for oil productivity index per meter,correction coefficient of time and interlayer interference coefficient are put forward.Using resistivity to correct oil productivity index per meter and multiple regression method to determine the interlayer interference coefficient are proposed at the first time,and it is of great guiding significance for the productivity evaluation of oil field in construction and the allocation of comprehensive adjustment wells.
