摘要

///In order to check the formation water flooded degree and distribution of remaining oil of various Putaohua reservoirs under the current well network condition, the authors deployed a confined coring well-examination. Based on the analytical data of oil-based mud coring and confined coring in the early production or pre-production stage, this paper made a preliminary evaluation of the reservoir, and analyzed the washing degree through identifying and calculating flooding. The result shows that Putaohua reservoir has the following characteristics: irreducible water saturation is relatively low, oil and water seepage range is wide, flooding degree is low, washing thickness is thin, washing degree is medium, and well producingdegree is low.
