摘要
渤海古近系中深层(埋深大于2 500 m的古近系地层)构造复杂,储集体埋藏深、相带变化大,储层预测困难,钻探失利井有一半以上因储层预测不准确而致。储层预测结果已成为制约渤海古近系中深层勘探成效的关键。基于工作实践,提出了适合渤海古近系中深层储层预测的技术思路与方法,包括陆相层序地层分析、古地貌分析、地震相组合与地震属性解释以及成岩动力学分析等。以辽东湾JZ-S地区沙一、二段储层预测为例,简要介绍了渤海古近系中深层储层预测技术的应用效果。
In Bohai Sea, the Paleogene mid-deep sequences have complex structures, deep-buried reservoir bodies and greatly-changed facies, resulting in difficulties in reservoir predication. More than half exploration wells in the Paleogene have failed directly because of inaccurate prediction of reservoir, and this predication has become a key to exploration success of the mid-deep Paleogene. Based on practical working, we have proposed a set of technologies and methods suitable for the reservoir predication in the mid-deep Paleogene, including continental phology, s sequence stratigraphy, palaeo-geomoreismic facies association seismic attribute interpretation and diagenetic dynamics. The paper takes Member 1 and 2 of Shahejie Formation in JZ-S oilfield as the examples, and briefly introduces the application effects of these technologies and methods.
