同位协同克里金方法在储层横向预测中的应用

The application of collocated cokriging in reservoir prediction

介绍了一种储层横向预测方法——同位协同克里金方法。同位协同克里金方法能够协同地震属性数据进行储层横向预测。在油藏开发评价阶段、滚动开发阶段和开发调整阶段,运用同位协同克里金方法,充分利用已知井较多的条件,在井数据体现的地质规律统计的基础上,结合井震数据开展储层预测,在应用地震数据区域分辨率较高特性的同时,能够更好地发挥井数据的作用。

A reservoir prediction method called collocated cokriging was presented. Collocated cokriging can unitedifferent seismic attributes to perform reservoir prediction. More cells are available in reservoir evaluation, roll-ing development and development adjustment stages. In such case, reservoir prediction on logging and seismic da-ta via collocated cokriging could take full advantages of well controls and seismic data.
