This paper is speaking about the geology characteristics, formation conditions and hydrocarbon accumulation features of the lithologic pinchout hydrocarbon reservoir in the third member of Shahejie Formation of Dongxin area. By analysing the factors which affects the progressive exploration ,it argues a method of new theory and high technology seismic constrained inversion to implement high efficiency exploration. Systematic interpretation was made to the characteristics, principles, applied conditions and affecting factors of seismic constrained inversion technology. With the experience of the exploration of Dongxin S3 lithologic pinchout oil reservoir, it analyses the application outcome of seismic constraint inversion of lithologic pinchout oil reservoir. It puts forward several important problems in the technology, proving the technology's reliability in seeking after the S3 lithologic pinchout oil reservoir. It not only has significance to the production, but also establish the base of seeking after the medium or little lithologic pinchout oil reservoir. The exploration theory of the lithologic pinchout hydrocarbon reservoir in the third member of Shahejie Formation of Dongxin area has been given a lot of abount content.
