Abstract: 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.

Key words: Anpeng field, imaging logging, stress, orientation
