Study On The Well-logging Method Of Interpretation Of Water-flooded Zones In Horse 20 Block

With more and more of the old oil field water injection development blocks high water cut exploitation phase, Ma 20 blocks of each layer subjected to varying degrees of flooding, has seriously flooded part of the reservoir. After the reservoir flooded, underground crude oil due to the long-term displacement and develop ways of influence of injected water, causing flooding relations are complicated, changing the original state of the injected water reservoir water distribution, and its physical parameters and lithology, oil and other parameters have undergone a series of changes, log response presents a diversity, which gives water flooded layer logging interpretation has brought great difficulties. In view of this situation, this paper horse flooded layer 20 blocks for the study, in-depth study of the distribution and longitudinal plane developmental status reservoir characteristics and physical properties of the sandwich to inspect sealed coring well data, core laboratory analysis and production, test oil and other information-based, technology-based 3D projection principle, according to the spatial location of the reservoir and flooded zone logging data response characteristics, the reservoir flooded situation and achieve qualitative judgment; and then find the appropriate fine reservoir parameters of the block evaluation model using mathematical methods of functional analysis and reservoir will log standardize logging response characteristics, physical properties and lower limits research information, and apply the appropriate interpretation handler reservoir parameters strike, Ma 20 blocks for a second Fine explained, Ma 20 blocks in order to achieve "qualitative, quantitative after" Logging Interpretation flooding. The results show that this method can improve the interpretation set flooded layer interpretation accuracy, achieve quantitative interpretation flooded layer.
