| Sandy Reservoir Prediction of the Shahejie Formation in Central East Depression, Liaohe Basin |
| It is necessary to do further research work on the prediction of the sandy reservoirs distributed in areas of insufficient core data. Aiming at solving the problem that the sand reservoirs were poorly developed in the target area of Central East Depression within Liaohe Basin, the authors carried out the research based on the sequence stratigraphy for the purpose of predicting the distribution of SQ2 TST sand bodies. The sand bodies in SQ2 TST are governed by paleotopography. The growth of faults and volcanic hills were studied comprehensively according to the data of 3-D seismography, wells and cores. It is shown that the accommodation space was remarkably expanded by the faulting activities, and the channel sand bodies were well developed along the surface of the sequence boundary during the rising cycle of the base level. However, the volcanic hills occupied the accommodation space of channel sediments. Therefore, the overbank flowing sediments were chiefly developed on the highs, while the channel sand bodies were distributed mainly along the lows. On the basis of the above discussions,the distribution of channel sand bodies was discovered, and the drilling engineering designed along the channels has been proved to be successful. |
