Through sequence-stratigraphic analysis and corresponding study for sedimentary environment of shell-clastic limestone in Daanchai Section,the paper discovered that the solution and leaching may be major factor which oil-gas accumulation is in thin-bedded limestone in Daanzhai Section and the fracture is only one of the favorable condition or necessary condition.The rich in oil-gas area of shell-clastic limestone in Daanzhai Section has been get by combination with using seismic parameters such as amplitude and sudden-changing coefficient,etc.The prediction results are coincident with real drilling results and studied results have been used for deployment of exploration and development.
