The application of seismic reconstruction inversion in Daqing Changyuan oilfield development zone

Daqing Changhua oilfield has been into a period of determining, transition zone have been closely watched as the basis of potential areas, but the transition zone has a problem of the low degree of use, conventional reservoir interpretation method is difficult to satisfy the requirement of accuracy. In order to solve this problem, by using the method of reconstructing separation with micro electrode resistivity curve and microspheres, which to establish a set of suitable for the technical flow transition zone in the oil field of fluvial faces reservoir prediction. Development of X in Daqing oilfield as an example, through the processing method of dimension the absolute difference and the amplitude difference of homogenization, which implement the process of logging curve reconstruction in the study area, and through four key link of inversion, complete separation reconstruction inversion in the study area. Confirmed by drilling, based on the separation seismic reconstruction inversion to predict drilling coincidence rate is higher, combining with seismic attributes such as achievement, supplemented by core, well logging, mud logging data, and complete S main reservoir sedimentary unit sedimentary microfiches in the study area. Comprehensive studies have shown that, this method is high precision to predict river, can be used as an effective method for prediction of oilfield transition zone channel.
