EFFECTFUL STAGE PERFORMANCE ANALYSIS CHART OF OIL PRODUCING WELLS WITH POLYMER FLOODING

In view of the different effectful lasting time and the great change of output and equipment parameters during the initial, middle and last effectful stages of the oil producing wells with polymer flooding, this paper introduces in detail the action of the effectful performance analysis chart of the oil producing wells with polymer flooding, the basic technical thought of the frame design, the principles for region determination, as well as the mapping method and principle of computers. This chart contrasts and analyzes the relevant data before and after the polymer taking effect, produces plot automatically through computer processing, and provides basis for production analysis and decision.
