摘要
地应力的大小和方向是石油勘探与开发中的重要参数。成像测井系列中的偶极子声波测井和微电阻率扫描成像测井为地应力研究提供了丰富的基础数据。根据安棚油田的地质特征和收集到的测井及测试资料,优选出合适的地应力计算模型,在此基础上,给出了用成像测井资料确定模型中各参数的方法,进而计算地应力。另外,也给出了利用成像测井资料处理结果确定地应力方向的方法。根据确定的方法对安棚油田的地应力进行研究,取得了良好的效果,能够满足现场生产的需要。
The size and orientation of stress are the important parameters in petroleum exploration and development. The imaging logging series such as dipole acoustic log and micro-resistivity scanning imaging log, etc. provides abundant basic data for the research of stress. This article selects the stress computation model fit for Anpeng field in accordance with the geologic feature and available well log and testing data, and then presents the method for computing each parameter required by the model using the imaging logging data. Moreover, the article proposes the method for determination of the stress orientation using the processing result of imaging logging data. Using these methods to research the stress of Anpeng field obtains good effectiveness which meets the needs of the field production.
