In order to improve the productivity of oil and gas fields,it is necessary to accu-rately predict the downhole sand production.However,the sand production situation is af-fected by a variety of factors,and the more common prediction methods include acoustic time difference method,B-index method,S-index method and experimental method.Howev-er,the parameters used in the above prediction methods are different,which may lead to dif-ferent conclusions using different methods for the same well data.In order to solve this prob-lem,the accuracy of the prediction method can only be improved,and the way to improve the accuracy is to consider multiple parameters as much as possible to judge the sand risk,so a comprehensive multi-parameter system of sand risk prediction method is needed.A new method for predicting sand production risk was obtained by weighting multiple methods by using the analytic hierarchy process,and the new method of sand risk prediction was used to predict the sand production risk of well LH28-2-1 in Liuhua 28-2 gasfield,and the results were consistent with the actual situation in the field,and the new method had good guiding significance for the prediction of sand production risk in oil and gas fields.
