Abstract: Long-term development practices showed that the development of lithological reservoir had been risky. The main reason is the uncertainty of the distribution prediction for the favorable lithology. The paper made an attempt to carry out study on the lateal reservoir predictions by applying such methods as impedance inversion of well-constraint waves, seismic factes analysis and reservoir parameter prediction with view to structural lithological reservoir in Wutonggou formation of Sha nan oilfield formed under the turbidite fan depositional environment, and pointed out the distribution range of the turbidite sandbody. Through practical development,it is proved that the prediction result is reliable. This indicates that integrated application of multiple reservoir prediction methods play an important role in accurate prediction of lithological reservoirs.
