利用多尺度资料进行油藏地质建模——以樊124区块为例
|
摘要
油藏地质建模是油藏描述结果的表现,是对油藏各种储层参数进行三维空间的定量描述。应用常规三维地震、井间地震、钻井取心、测井曲线、开发动态等多尺度资料进行对比和油藏描述研究,可建立精细的三维构造格架模型、储层参数模型、沉积相模型、流体模型等。利用该技术综合解释了樊124区块中部低序级断层,明确了油水关系,解决了开发中存在的注采矛盾,建立的三维定量油藏地质模型为科学制定开发调整方案提供了可靠的依据。油藏地质建模在解决开发生产难题、提高油藏最终采收率方面有较好的应用前景。
Reservoir geological modeling shows the result of reser- voir description which quantitatively describe all kinds of reservoir parameters in 3D space. Multiple scale data that include conventional seismic, cross-hole seismic, coring by drilling, well log, development performance and so on, were applied to comparison and reservoir description research, then various fine models consisting of structure model, reservoir parameter model, sedimentary facies model and fluid model were established. This technology was applied to comprehensive interpretation on the existence of low-sequence-order faults in the middle of Fan124 block, to making the oil-water correlation clear, to resolving the injection-production contradictions during development. The established 3D quantitative reservoir geological model for the studied area provided reliable foundation for making development plan scientifically. The reservoir geological modeling has better prospect in solving oil development difficulties and enhancing oil recovery of oil reservoirs.
