摘要:

莺歌海盆地莺东斜坡带上第三系地层岩性圈闭发育,油气成因类型多样,纵向上生储盖组合良好,是莺歌海盆地有利的天然气聚集指向区。从骨架砂体、断层、不整合面和其上砂体以及三者的组合特征,对莺东斜坡带上第三系天然气输导系统的分布特征进行了研究。利用断层应力环境、断层与砂体对接情况、断层活动期与成藏期的关系、骨架砂体发育程度和不整合面及其上砂体的分布等5个因素对该输导系统作了初步评价,发现莺东斜坡带北段为一般输导系统,中段为较优质输导系统,南段为优质输导系统。

关键词: 骨架砂体, 不整合面, 断层, 输导系统

Abstract:

Yingdong slope is an advantageous area in Yinggehai basin, on which there are lots of stratigraphic and lithological traps. The founded gas reservoir shows that the natural gas are from mature source rock of the sag in the Yinggehai basin and the deeper belt between the slope and mud diapir in the sag or the deeper belt of the fall side of the No.1 faults. The conditions of source-reservoir-seal are favorable. In this papers the transfers system on upper Tertiary of natural gas of Yingdong slope which are divided the north belt, middle belt and south belt according to the No.1 belt were analyzed based on the sand bodies, discontinuity surface(S40), faults and combination of these three former. There are less frame sand bodies on the north and middle belts but more frame sand bodies in the south belts and the No.1faults in the north  belts are inactive and locked. The No.1 faults of the middle and south belt are active and unlocked. The sand on the discontinuity surface(S40) were distribute widely in the south belt while hardly any in the north and middle belt. It were found and identified that the natural gas transfer systems on upper Tertiary of south belt of Yingdong slope would be most advantageous, the middle belt would be more advantageous and north belt would be advantageous, which based on the appraising by these five parameters including stress state of faults, the sand bodies between the upper and lower of faults, the period of the faults activity and the forming time of gas reservoirs, the distribution of framework sand bodies and the sand bodies on the discontinuity surface(S40). 

Key words: Frame sand bodies, Discontinuity surface, Faults, Transfer system of natural gas.
