台北凹陷东部勘探潜力分析
|
摘要
随着吐哈盆地勘探程度的不断提高,取得新发现的难度越来越大,尤其台北凹陷东部作为吐哈盆地天然气的主战场,多年来开展了大量的研究工作,但由于受复杂的构造、多变的沉积环境、品质较差的地震资料等因素的影响,对台北凹陷东部认识程度难以提高。通过近几年来处理解释一体化攻关,及对东部构造及沉积的系统研究、整体认识,我们提出了山前带复杂构造、弧形带深层、南部斜坡带岩性三个下步有利勘探方向及一批建议优先钻探的井位目标。
With the increasing of exploration in Tuha basin, it is more difficultly to discover new hydrocarbon reservoir, especially for eastern Tabei sag. A large quantity of researches have been carried out in the east of Tabei sag for years, it is difficult to improve the understanding of eastern Tabei sag due to some affecting factors such as complicated structure, variable sedimentary setting and poor quality seismic data. Based on tackling the difficulties of processing and interpretation integration, systematic study and overall understanding of eastern structure and sedimentation, three following favorable exploration targets include piedmont complicated structure, arcuate deep zone and southern slope belt lithology are raised, and some suggestion on well location targets which should be preferentially drilled is proposed.
