摘要：

Niuju Area is located in the north of the East Depression, Liaohe Basin, thin inter-bedded sands and shales are main sedimentary characteristics of reservoirs, and the thickness of a single bed is mostly less than 5 meters. Therefore, high-resolution impedance inversion is needed. Firstly, we carry out qualitative and quantitative prediction of thin beds based on reservoir calibration and forward modeling. Then, with multi-attribute comparison we select maximum trough amplitude attribute that can effectively show the distribution characteristics of sand bodies. Afterwards, reservoirs are predicted with the high-resolution impedance inversion provided by GeoEast. Finally, the sand thickness prediction is achieved with the threshold value method. Our prediction has a coincidence rate of 78.6%, which is very helpful for the improvement of exploration drilling success rate. © 2018, Editorial Department OIL GEOPHYSICAL PROSPECTING.
