Abstract The lithological oil gas pools mainly consist of lens shaped sandrock and up tilted pinching sandrock oil reservoirs in Dongying Sag. 東營(yíng)凹陷巖性油氣藏主要為砂巖透鏡體油氣藏和砂巖上翹尖滅油氣藏。
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(fā)育有巖性油氣藏,前緣隆起由于地層向克拉通方向尖滅,常形成巖性油氣藏。
