RESORACH AND ASSESSMENT OF OIL-GAS POTENTIAL OF THE MESOZOIC ERATHEM IN THE COASTAL O THE JIYANG DEPRESSION

he coastal area of the Jiyang depression refers to the Northeastern part of JiyangDepression along the Bohai sea coast line,The mesozou strata in this area is well developed;theyinclude four layers:the Fangzi formation of the Lower and middle Jurassic system,the Menyinformation of the wller Jurassic system, the Qingshan formation of the Lower cretaceous systemand the Wangsi formation of the upper Cretaceous system,On the seismic profile the four layersexhibit gOOd boundary surface reflection.Oil and gas is very rich in the Mesozoic erathem in this area where there are three oil bearinghorizons and three types of hydrocarbon accumlations(pools).1.e,,buried hill pool, fault blockppol,and lithostraligraphic pool.Six prospective oil and gas lands are predicted.
