摘要
通过分析油气分布及其与源岩、盖层、储层和构造之间空间分布关系,对海塔盆地中部主要断陷带南一段油气成藏条件进行了研究,得出海塔盆地中部主要断陷带南一段油气之所以富集是因为以下4方面的有利条件:①2套主力源岩为南一段油气聚集成藏提供了充足的油源;②2套区域性盖层为南一段油气聚集成藏提供了有效封盖保存条件;③扇三角洲前缘亚相砂体为南一段油气聚集成藏提供了良好的储集空间;④反向断裂翘倾隆起和洼中隆为南一段油气聚集提供了有利条件。
By analyzing the oil and gas distribution and its relation to spatial distribution, spatial distribution sourcerock, and sourcerock, caprock, reservoir and struclwres, the formation conditions of oil and gas accumulation of K1n1 in the central depression of Haita basin was studied, It is considered that there are four following favorable conditions for oil and gas accumulation of K1 n1 in the central depression zones of Haita basin.. （1）Two sets of source rock provide enough oil and gas for accumulation of K1 n1 ; （2）Two sets of caprocks provide effective sealing conditions for oil and gas accumulation of K1 n1 ;（3）Front sandbody of fan delta provide reservoir space for oil and gas accumulation;@Reverse fault tilting and uplift in sag provide favorable places for oil and gas accumulation.
