三维地质建模技术在油田基础地质研究中的应用

基于钻井资料的三维地质建模技术,通过在留楚油田建立精细的三维地质模型,使油藏研究达 到较高的精确性。在建模过程中,将三维建模软件特有的技术手段与基础地质研究相结合,在构造精细 落实、地层精细对比等基础地质研究方面发挥重要作用,解决了许多通过常规方法难以解决的问题。精 细地质模型在C2020井开发措施调整及C2945井注采关系分析等方面取得了良好的效果。由于三 维地质模型是地质体的一种数字化表述,因此,它还在数字化油藏方面起到了重要作用。

3D geological modeling in studying oilfield geologiy

Borehole data based on 3D geological modeling are a powerful geological study tool in reservoir development. By generating fine 3D geological model in the Liuchu oilfield, the reservoir study reaches to high accuracy. It also plays a im- portant role in the high accuracy structure study and stratigraphic comparison. Combining the special technique of 3D model- ing software with essential geological study in the procedure of geological modeling can solve many geological problems that used to be basically unsolved by traditional. The geological study based on the fine geological model led to a satisfied result, for example, in the production adjustment of well C29-20 and in the inject-production relationship analysis of C29-45 area. Because the 3D geological model is a digital presentation of reservoirs, it also occupies an important position in digitizing a reservoir.
