Abstract The lithological oil gas pools mainly consist of lens shaped sandrock and up tilted pinching sandrock oil reservoirs in Dongying Sag. 東營凹陷岩性油氣藏主要為砂岩透鏡體油氣藏和砂岩上翹尖滅油氣藏。
The lithologic oil and gas reservoirs are developed in the foredeep depression zones and forebulge zones due to the cratonward pinching of strata. 前淵凹陷帶主要發育有岩性油氣藏，前緣隆起由於地層向克拉通方向尖滅，常形成岩性油氣藏。
