The research and application of lithologic hydrocarbon reservoirs prediction in sedimentary system tract:An example from Mesozoic Yanchang Formation in northern Ordos Basin
Online published: 2007-06-15
Referring to the master factors of lithologic hydrocarbon reservoirs of Yanchang Formation, the authors make full use of the effective seismic information on the basis of the curve lines in Huangtuyuan area to carry out seismic reservoir lateral prediction in target stratum. Five methods summarized according to the identification of the permeable sandstone distribution section and plane figures of permeable sandstone distribution provide some evidences for drilling location. The late drilled well assessment proves that the coincidence rate of the permeable sand thickness prediction is over 80%.
