| Linjiang region run across Changchun ridge anticlinal belt and Bin county Wangfu sag Secondary construction units, exploration area is 2000km2,There have been found proved reservior of natural gas 99.58×108m3and petroleum controlled reservoir 2164×104t. But in the circle which area is 1500km2 in the center of Wangfu sag that contain oil universal. And single well test rate is lower, generally between 0.08-3.615t/d. The achievement have get shows that oil and gas favorite area is mainly controlled by intricate and linked river channel of Fu-Yang oil formation, the more nearer to sag center the more requirement to reservoir layer. Therefore, if we want to find high yield enrichmental block, so as to form scale reservoir, we must have divided river channel sand body meticulous, practice its contribution rule, and combined with rupture, contribution of effective hydrocarbon source rock to determine oil gas enrichment area. This thesis takes sequence stratigraphy, sedimentlogy, petroleum geology etc theories as its instrument and take three dimensional seismic explanation technology, high resolution seismic inversion technology, depositional facies analysis technology, oil-gas layer comprehensive evaluation technology as its Support. and used well logging , logging, seismic, test oil and core analysis date to operate comprehensive research of deposition, reservoir, oil-gas pool. Main achievement includes. (1) take sequence stratigraphic theory as instruction divided and compared to strata in entire area, and make a deep division to Fu-Yang formation and get five oil formations and by combined with seismic date to operate layer tracing and comparison. (2) Used common slices Mould slices, mercury injection data to have micro porosity construction research of river channel sand body. Combined with core porosity and permeability, and well test result, Fu-Yang formation was divided four type formations deeply in quantity. (3) According to river channel scale, river channel was divided into mainly and secondary channel. According to its development period, river channel was divided into single period river channel, double period river channel ,tri-period river channel, and multi-period river channel ,and take formations as unit to statistic development degree of river channel, and debated river's development regular in different geologyphic period. (4) Used core, well logging and seismic data to determine Fu-Yang formation is low lake delta facies deposition, its typical character is pain facies belt over water is wide, and plain facies belt under water is narrow. Based on facies-analyzing, seismic facies and result of seismic inversion facies of five oil formations in entire area have been make out and river channel's development has been described. (5)Adopted trap expert evaluation method, used following research achievements select evaluation parameter in optimum seeking, have contracture fault trap ordering optimum seeking, then put forward there have four favorite traps. Used ruptures, effective hydrocarbon source and sand body polymerization, make a prediction that there have four favorite lithologic traps. (6)Used achievements listed in this thesis, laid Shuang51 well success ,drilling meet two layer main river sand body in F3 formation which is 12.4m, the well test production is 5.6t per day, as a result set up a new phase of oil-gas exploration in the south slope of Wangfu sag in Linjiang region. (7) According to core data analysis and well test result the thesis determines that the limited depth of oil exploration of Fu-Yang oil formation for main river channel sand body in Wangfu sag is 2050m. The research achievements are not only to guide next step of laying wells in Linjiang region, but also used for important reference to exploration in Daqing placanticline, Sanzhao sag and Gulong sag of Fu-Yang oil formation in Songliao basin.
