Application of field evaluating technique on information damage of T well in Tazhong

Through an analysis of the total skin which is acquired from well test evaluation, information damage skin factor (an index of extent of formation damage) is acquired. In accordance with the skin factor, the formation damage radius and the well forecast stimulation rate are both determined, and then a set of field evaluation technique on information damage is formed. This technique shows great accuracy and is of more practical value through its successful application in Tazhong.
