茨榆坨构造带中段构造上属于翘倾断块披覆背斜构造带,通过对油气成藏条件进行分析,并依据复式油气成藏理论,认为其低断阶带是滚动勘探的首选目标,关键是寻找控油断层和圈闭。基于此种认识,以二维和三维构造精细解释技术为基础,综合运用其它配套的地震新技术,新发现了一个1 千万吨级优质储量区块———茨601 块,成为近年来辽河油田油气勘探的重大发现之一,对老区的滚动勘探具有重要的指导意义。

The middle section of Ciyutuo reservoir lies in the north of east depression in Loaohe basin , since 1970’s ,no exploration had been made in low section of the region , In 1995 , based on multiple oil and gas reservoir forming theory , it was thought that the key factor of rolling exploration is to discover the faults and traps to control oil. Through 2D and 3D fine structure interpreation ,and combining with the new necessary seismic technique , the high production block - Ci 601 Block was discoved ,in which the oil production was ten million tons or so ,and it is one of the significant discovery of oil and gas exploration in Liaohe Oilfield ,having an important guidance for rolling exploration of maturing oilfield.
