High Rsolution Sequence Stratigraphy And Favourable Target Prediction Of Shahejie Formation, Nanpu Depression

In order to operate"Highly accurate sequence stratum and beneficial aims from Shahejiegroup of Nanpu depression"progect we will make the study of it, establishing the pattern ofsepuence stratum by the third level sepuence from Shahejie group of Nanpu depression,recognizing the composed feature and model of sequence system tract from this depression,clarifying the sandstone of lowstand systems trace about beneficial aims, studying the sand ofdeveloped regularity and controlling factor of expending systems,which arranges the highlyefficient hydrocarbon source rock. According to the pre-well face and cross section wells,graphers of stratigraphy thickness, sand thickness, rate of sand tostratigraphy, sedimentarysystem expending, analysing sequence seismic cross section, we supply the theory guide ofexplorition to beneficial aims. By the study of this thesis we foreseeing a method of forecast andexploration from Nanpu depression, which is a significant exploration. By the aim and train of thought, we have finished four sides research: 1.Building the discerned sign from the boundary of sequence stratum; 2.Building the sametime sequence pattern by the third sequence as residiential unit; 3.Thorough studying in sediment faces and sediment system of emphasis sequence; 4.Prospecting the beneficial aims. By this thesis, we have gained 3 achievement: â‘ Building the sametime sequence pattern by contrasting and tracking the boundary ofsequence stratum,which helps to study the sediment system and prospect the reserves; â‘¡Finding alluvial fan,braided river course-braided delte,submarine fan,fan delte andlacustrine faces in old tertiary; â‘¢Prospecting 7 beneficial aims in old tertiary,by the well drillings of the oil field,findingsome success in fan delte of highstand systems tract from sequence 2.
