Identification Research about Low Permeable Water Flooded Layer in West of Daqing
Abstract. A is a typical low permeable oilfield in surrounding region of west daqing, the major target layer is Saertu formation,which posseses characteristics of reservoir thin, poor physical property and more containing mud and calcium, in addition, conventional logging respons characteristic is not obvious in flooded layer, leading to distinguish it more difficult. To solve this problem, the paper researches it from the mechanism of electric conduction, and classified establishes explaining plate about flooded layer, at the same time taking into account logging boundedness, which makes use of results about logging and dynamic flooded analysis to replenish and correct logging explaining result in flooded layer. We establish synthetical explaining method. Using this method, the coincidence rate of flooded layer explaining result achieves 75%.
