摘要:
渤海B油田明化镇组下段发育典型的浅水三角洲储层,浅水三角洲复合砂体为多期次单砂体切割叠置形成,内部非均质性强,同时海上油田稀井网大井距,也给深入分析储层内部结构带来了困难。为进一步提高砂体动用程度及开发效果,在储层地质学理论指导下,应用海上高分辨率地震资料、丰富的动静态数据,基于砂体的井震响应特征,对主力砂体开展精细解剖。总结了砂体成因类型及叠置关系,形成了井震约束下的单砂体构型解剖思路,明确了砂体构型边界及接触关系,提出了不同类型砂体构型解剖方法。在单砂体构型解剖的基础上,融合地震地质信息,建立三维构型模型。研究表明,井震约束下的砂体构型解剖及界面等效表征在渤海B油田的地质建模及油藏数值模拟中取得了较好的应用效果。
Abstract:
Typical shallow-water delta reservoirs are developed in the lower part of the Minghuazhen Formation of B Oilfield in the Bohai Sea. The shallow-water delta composite sand- body is formed by multiple stages of single sandbody cutting and superimposition, and the internal heterogeneity is strong.At the same time, due to the sparse well pattern and large well spacing in offshore oilfields, it is also difficult to in-depth analyze the internal structure of the reservoir. In order to further improve the production degree and development effect of main sand bodies, under the guidance of the reservoir geology theory, by applying the offshore high-resolution seismic data and abundant dynamic and static data, based on the seismic response characteristics of sandbody, it was carried out fine anatomy of the main sandbody. And then it was summarized the genetic types and superimposed relationships of sandbodies, and it was formed a single sandbody configuration anatomy under the constraint of well seismic.The configuration boundaries and contact relationships of sandbodies were clarified, and different types of sandbody configuration anatomy methods were proposed.Based on the configuration anatomy of a single sandbody, a three-dimensional configuration model was established by integrating seismic and geological information. The study shows that the structural anatomy of sandbodies and the equivalent characterization of interfaces under the constraints of well earthquakes have achieved good application effects in the geological modeling and reservoir numerical simulation of Bohai B Oilfield.
