Lithological reservoirs are developed in below abnormal hig h-pressure system, by analyzing character of the distribution of pressure of ea rly-Tertiary in Dongying Depression and its response to the lens' hydrocarbon a ccumulation. The distribution of abnormal high-pressure is in accord with sourc e-subdepression in plane on the whole. Pressure coefficient is higher in north region and lower in south region, which is correspond with the distribution of u ndercompaction region. The main factors, which led to Es3 abnormal high-p ressure in Dongying depression, are undercompaction and hydrocarbon generation. Hydrocarbon accumulation of lens reservoirs are controlled by the distribution o f abnormal high-pressure. Lens reservoirs, enveloped in dark mudstone, is mostl y distributed in relative low-pressure region. Microfracture and episodic expul sion hydrocarbon of mudstone are generated by pressure difference between mudsto ne and lens. Sandstones have relative high fluid pressure after hydrocarbon filling.
