Research On The Well-logging Technique And Method Of Interpretation Of Water-flooded Zones In Huabei Oilfield

The bed has been water flooded for several years in the Hua-Bei oil filed, most regions go into the stage of the high water-flooded , and the oil bed was serverely water flooded. the production of oil-saturation bed is affected by the existence of the water-flush bed , many problems need to be solved such as the effect of injected water .In this paper the two methods are proposed, the first is about the interpretation method using the conventional logging data in open holes and the second is the one using the cased holes. According to the theory of the seepage ,the interpretation models and the interpretation criterions are established.and are tested in many holes..but the conventional logging datas are not adapted to the cased holes, the curves of C/o,RMT,neutron gamma are used to monitor the distribution of the saturation gof residual oil,and the identify the property of the oil and water and to judge the water flooded degree . at the same time ,the many kinds of interpretation are established and tested in many holes.
