The type of trap is the large - sized lithologic trap showing a north - south extent band 气藏类型为南北向条带状发育的大型岩性圈闭。
Analysis of the formation stages of the paleogene lithologic traps in the southwestern caidamu basin 柴西南区古近系岩性圈闭形成期次分析
Characteristics of evolution and distribution of lithologic trap in dongying delta , shengli oilfield 东营三角洲演化特征与岩性圈闭分布规律
The lithologic traps can be further divided into two types , i . e . primary and secondary lithologic traps , according to forming mechanisms 根据形成机理,将其岩性圈闭进一步划分为原生和次生两种类型。
Early generation of lithologic traps coupled with early hydrocarbon charges make the early formation of oil accumulation possible 岩性圈闭形成的早期性和岩性油藏的相对早期充注可能是产生岩性油藏相对早期形成的主要因素。
