吐哈盆地台北凹陷水西沟群有利勘探区带预测
|
摘要
以台北凹陷水西沟群2套主力层段三工河组上段(J1s上)和西山窑组一段(J2x1)为研究对象,研究沉积体系、储层特征和关键成藏时期的古构造,明确有利储集相带,分析主要储集空间类型与储层分布规律.结果表明:浅水辫状河三角洲前缘的水下分流河道砂体是有利储集体;粒内溶蚀孔、基质晶间微孔和微缝是主要储集空间;关键成藏期以来的持续古构造高部位和断裂发育部位更利于发生溶蚀作用,是有利储层分布区,预测台北凹陷4个有利勘探区带,是下一步勘探方向.
To confirm favorable reservoir facies and analyze the main reservoir types,reservoir distribution of two main layers of Shuixigou group(the upper member of Sangonghe formation and the 1st member of Xishanyao formation)in Taibei sag,sedementary system,reservoir characteristics and crucial hydrocarbon accumulation period palaeostructure have been systematically studied.The results showed that sand body of underwater distributary channel in shallow braided delta front is favorable reservoir.Intragranular dissolution pores,intercrystalline pores and micro-fractures are main reservoir space.Denudation is more conducive to occur in fracture zone and everlasting paleostructure high position since crucial period of hydrocarbon accumulation,which are favorable reservoir distribution area.Based on studies above,four zones are predicted to be favorable targets for further exploration.
