| 摘 要： | 在进行水力压裂微震资料处理时,建立正确的速度模型是非常关键的。它的准确与否直接影响微震反演定位的精度。本文就如何建立比较准确的速度模型进行了研究,首先根据多种资料建立初始速度模型,然后通过射孔反演校正初始速度模型,最后得到比较准确的速度模型,通过实例应用证明此方法可行。

| Abstract: | It is important to establish correct velocity model in the hydro-fracturing microseismic data processing.Whether to build it accurately or not may directly affect the precision of microseismic inversion location.This paper makes the research on how to establish relatively accurate velocity model.Firstly,it is necessary to establish initial velocity model based on many kinds of data.Then,initial velocity model is needed be adjusted by shooting inversion.Finally,relative accurate velocity model may be gotten.This method is proved feasible by the application example. |
