Discusses the technical principles and characteristics of the Jason well-logging constrained seismic inversion.The buried oil-gas reservoirs of the Tertiary stream facies in the Zhuang 106 massive pool of the Shengli oilfield have different thicknesses and complicated oil-gas accumulation and formation.According to the above-mentioned features, the technique of well-logging constrained seismic inversion was used in the description of oil-gas reservoirs in the Guantao stream facies strata which includes the synthesis of seismic record demarcation, the reasonable selection of inversion parameters and the establishment of a high-quality well model. In this work, a perfect geological model was built up on the basis of the inversion results, which authentically realize the inversion of the three-dimensional high-frequency seismic data.It made certain of the distribution laws of the oil-gas reservoirs and favorable lithofacies traps in the surveyed area and the 3 to 5 m thick oil-gas reservoirs can be distinguished from the surveyed area.The use of Jason well-logging constrained seismic inversion gave birth to a better application effect.
