测井约束反演及在JD地区的应用
|
摘要
利用测井约束反演的方法,通过STRATA反演处理研究K1c2上部地层的平均层速度变化规律和异常压力,分析出较为准确的层速度等参数,在此基础上对该区的异常高压与流体势进行计算。在提取K1c2地层速度的基础上对地层压力和流体势进行了计算,获得了这套地层的地层压力和流体势的平面分布情况,通过地层压力平面分布及流体势平面分布情况,了解凹陷内流体流动方向,即油气运移的方向,从而为进一步勘探提供明确的目标。
This paper analyzes the horizon velocity parameters based on the well logging constrained inversion technique through using the STRATA inversion to study the change laws of average horizon velocity,abnormal pressure,and fluid potential in upper K1c2 formation. On this basis,the abnormal pressure and fluid potential are calculated in the area and the reservoir pressure and fluid potential are computed in terms of the extracting of horizon velocity of K1c2 formation in the area. The plane distribution of reservoir pressure and fluid potential has been obtained for this set of strata. The flow direction of fluid,i.e. hydrocarbon migration direction,has been understood within the sag according to the plane diagram of reservoir pressure and the plane diagram of fluid potential,which provides a definite target for further petroleum exploration.
