Abstract: Prediction of pre-drilling strata information is necessary in the process of oil and gas exploration and development. VSP technology is a commonly used prediction method. Traditional VSP method only uses upgoing and downgoing waves to predict the depth of pre-drilled strata,and the accuracy of the predicted stratigraphic depth is limited. So far,few scholars have studied attribute prediction methods based on VSP data. A new method for predicting formation depth and hydrocarbon attributes by using VSP multi-wave information was proposed. This method makes full use of the abundant wave field information of VSP. Firstly,the multiple events related to the target layer were tracked in the data,and according to the tracked result,the discrete function groups were built,and the overdetermined equations were solved separately. Then the statistical weighting method was used to obtain the final prediction depth. This method can reduce the uncertainty of the prediction results and greatly improve the accuracy of the formation depth prediction. After obtaining accurate formation depth data,the differences between compressional wave and shear wave were calculated and used to predict the hydrocarbon attributes. The practical application effect was proved by two examples of VSP projects in western China.

Key words: vertical seismic, VSP multi-wave, strata depth prediction, hydrocarbon attributes
