波阻抗反演在储层预测研究中的应用

随着勘探开发的不断深入, 对油气田的老区勘探开发及二次评价，在储层预测研究上，如何更有效地识别碎屑岩储层及变质岩储层，最大限度地降低波阻抗反演过程中某些不确定性因素造成的影响，以确保储层预测的精度，提高钻探的成功率. 波阻抗反演在以上两种储层反演预测的过程中，能够充分利用钻井、测井、试油、试采等动态、静态资料，更好的对地下地质体进行高精度反演预测，找出油气藏储层在纵向、横向上的分布规律，为井位部署及储量上报提供可靠的依据.

Application of wave impedance inversion to reservoir prediction research

With steady development of exploration, further exploration and second evaluation to old oil-gas field have become an important issue. In this aspect, we need to study how to discriminate metamorphic and clastic reservoirs, and reduce the effect certainties in the wave-impedance inversion as much as possible, which can help enhance accuracy of reservoir predication and success rates of drilling. For the prediction of two kinds of reservoirs aforementioned, wave-impedance inversion can make full use of available data, such as borehole, logging, oil tests and other static and dynamic measurements. It can help probe geological bodies in the subsurface, find rules of reservoir distribution in vertical and horizontal direction, and provide evidence for well deployment and reserve estimation.
