温西一、陵2中块储层沉积单元精细对比
|
摘要
以Vail层序地层学和T.A.Cross发展的高分辨率层序地层学理论为指导,以油田辫状河-扇三角洲沉积理论研究成果为基础,依据精细油藏描述的要求,对温西一、陵2中研究区块三间房组储层沉积单元划分与对比展开再研究。采用"分级旋回控制,等时对比"的原则,在一个特定油田范围内,用多级标准层、标志层和高分辨等时界面控制约束,纵向上按照沉积旋回级次逐级控制,逐级对比,区别对待,横向上对储层沉积单元依据其沉积机理采用适宜的静态对比方法,做到点线面闭合。对疑问井层储层连续、连通问题和隐蔽的小断层除采用地震、测井倾角资料和储层反演多项资料综合分析外,还结合动态资料加以验证,做到油层静态和动态的统一。
Taken Vail's sequence stratigraphy and T. A. Cross's high resolution sequence stratigraphy as guideline, and based on the study result of braided channel-fan delta deposition theory, the sedimentation units division in Sanjianfang group of the interest area of block Wenxil and middle Ling2 are investigated, according to the requirement of fine reservoir description. On the principle of "cyclothem control by order, isochronal correlation" , multiple order datum beds, horizon marker and high resolution chronohorizon are used to control restraint, in a specific range of the oilfield. In vertical direction formation correlation was controlled by the sedimentary cyclothem which makes a difference between reservoirs, and in horizontal direction proper static correlation methods were introduced in reservoir sedimentary formation correlation, which can close in point, line and surface. The continuity and communication of questionable reservoir and subtle faults were not only comprehensively analyzed by the use of seismic, oblique angle data and reservoir inversion data, but also were validated with performance data, so that reservoir can be kept in consistency under static and dynamic state.
