Abstract: It is difficult to understand and develop the low resistivity reservoirs. This article analyzes the reason causing the low resistivity reservoirs and applies new technology to deal with log data so that the pre-cision of recognize of the low resistivity reservoirs. The methods of test oil and content oil state were adopted to set up the plate of recognize of the low resistivity reservoirs. The know of the low resistivity reservoirs play an important role in rolling development and cognition of reservoir,in the meantime,make this oilfield turn into an avail areas of adding reserves and building the output of oil.
