Its range is relatively small . the latter ' s range is broad , belonging to the gentle - slope style . the bottom stratum developed a set of turbidite - fan 5 、研究了以欧39井沙三下为代表的储层的成岩作用,为评判储层的优劣提供了依据。
According to the cores and seismic data , the most important facies is fan - delta in this area , mainly developing in the top member and the bottom member developing turbidite - fan 在以上认识的基础上,首次建立了工区沙三下、中、上沉积相展布模式。
Mudstone deposited in deep water envoirment of sq6 - sq8 is the better regional sealing bed . the deep lake turbidite regionally deposited in sq6 - sq8 with better feature 层序6 8沉积的深水湖相泥岩是本区良好的区域性盖层,局部区域出现的深水浊积扇砂岩物性较好。
Vertically , a series of turbidite fans and fan deltas developed along eastern border of guxi contemporaneous fault zone and sandbodies were overlaped with each other 垂向上,沿东部边界孤西同生断裂带发育的一系列浊积扇和扇三角洲由于迁移摆动,砂体可以相互叠置连片。
So , the study of the depositional character of the turbidites and the descriptive methods of the turbidite oil reservoirs has important real - life signifcance in the exploration development of the trubidite oil reserviors 因此,研究浊积岩储层的沉积特征和浊积岩油藏的描述方法对于浊积岩油藏的勘探开发具有重要的现实意义。
