处理解释一体化在渤海黄河口凹陷新近系勘探评价中的应用——以A构造为例

The application of integrated research for interpretation and processing in Neogene exploration of Huanghekou sag,Bohai bay:A case study of structure A

渤海黄河口凹陷新近系晚期断层发育,浅层圈闭破碎且多以构造-岩性为主,地震资料品质制约着该区的构造解释以及河流相储层的精细描述。常规处理有时不能准确把握地质认识并充分利用已钻井信息,为此开展处理解释一体化研究,建立起测试-评估-反馈-修改的迭代式一体化流程,对接实际问题,集成各种先验认识进行关键环节、参数优化。实践证实,一体化资料能较好解决A构造评价中部分问题,也有力支撑了该区下步勘探。

Faults of late Neogene are well developed in Bohai Huanghekou sag that the shallow traps are broken into pieces,forming the most important structural-lithologic type.As a result,the quality of seismic data is the primary course of structure interpretation and fluvial reservoir refined description.Regular processing sometimes can't discover the nature of geology understanding and make the best of existing drilling information.Therefore,integrated research for interpretation and processing is carried out,creating an iterative flow:test-evaluation-reaction-correction,joining the key process part with prospect problems,optimizing the key points and parameters with drilled prior cognition.The practice showed that integrated processing data helps in dealing with some problems in the exploration evaluation of structure A,and supports next prospecting efficiently.
