Research about control factors and early warning system of early warning system in Song Fangtun Oilfield

摘要

The development effect of Song Fangtun Oilfield is mainly restricted by two factors which are geology and exploitation. In view of the main control factors in oilfield development, we selected two indexes, monthly average decline range and water content escalating rate to establish early warning system of blocks development effect. The system which has great practical application value, is sensitive to reflecting the monthly variation process of block development effect, and plays a certain guiding role in the development effect during the whole year.
