Abstract The lithological oil gas pools mainly consist of lens shaped sandrock and up tilted pinching sandrock oil reservoirs in Dongying Sag. 东营凹陷岩性油气藏主要为砂岩透镜体油气藏和砂岩上翘尖灭油气藏。
The lithologic oil and gas reservoirs are developed in the foredeep depression zones and forebulge zones due to the cratonward pinching of strata. 前渊凹陷带主要发育有岩性油气藏，前缘隆起由于地层向克拉通方向尖灭，常形成岩性油气藏。
