摘要:

阿克墩地区位于塔里木盆地沙雅隆起轮台断裂以南,其苏维依组为油气田的主力产层.采用圈闭层封闭面成图技术方法对苏维依组进行分析,发现该组顶部存在构造-岩性型复合圈闭.此圈闭由个鼻状构造组成,每一构造在不同甚至相同的剖面上,反映出的构造形态及圈闭类型各不相同.在地震剖面上,该圈闭顶界面具有强振幅、长连续反射及尖灭点位置易于识别的特点.阿克墩地区苏维依组复合圈闭的发现表明,就目前地震勘探的分辨率而言,采用圈闭层封闭面成图技术对复合圈闭具有较好的判识效果.

Abstract:

Akedun is situates in the southern part of Luntai fault in the Shaya Uplift,Tarim Basin.The Suweiyi Formation in it is the major pay bed.The formation was analysed by chart stacking technology along the sealing surface of the trap,a large tectonic lithologic complex trap was found in the top of the formation.The trap is composed of three nose structures,each one has different configuration and trap type.In seismic profile,the top surface of the trap is characterized by high amplitude,continuous reflectance and easily recognized pinch out.The discovery of the trap shows that the chart stacking techonogy with trap sealing surface could obtain better discrimination result.

Key words: complex trap, chart stacking technology, Suweiyi Formation, Akedun Region
