The type of trap is the large - sized lithologic trap showing a north - south extent band 氣藏類型為南北向條帶狀發(fā)育的大型巖性圈閉。
Analysis of the formation stages of the paleogene lithologic traps in the southwestern caidamu basin 柴西南區(qū)古近系巖性圈閉形成期次分析
Characteristics of evolution and distribution of lithologic trap in dongying delta , shengli oilfield 東營(yíng)三角洲演化特征與巖性圈閉分布規(guī)律
The lithologic traps can be further divided into two types , i . e . primary and secondary lithologic traps , according to forming mechanisms 根據(jù)形成機(jī)理,將其巖性圈閉進(jìn)一步劃分為原生和次生兩種類型。
Early generation of lithologic traps coupled with early hydrocarbon charges make the early formation of oil accumulation possible 巖性圈閉形成的早期性和巖性油藏的相對(duì)早期充注可能是產(chǎn)生巖性油藏相對(duì)早期形成的主要因素。
