In allusion the physical property of Tertiary Reservoir and characteristics of sand production in YMX Oilfield, the matching techniques for sand fallout and fracturing at the end of sandstone were studied and tested. A full 3D fracturing simulation method was used to optimize the its fracturing (fracture length of 40m, the optimal fracture conductance ability being 0.4~0.6μm2·m). Technique of height control with diverting agent is used to effectively prevent water zones to be fractured. The effect of fracturing was guaranteed by using the matching technique of rapid backflow, pretreatment of formation. The method is used in 4 wells with 100% success rate, single well production rate is raised to 12.8t/d from 3.6t/d. the validate period is 24 months. The problems of low production and sand production are effectively solved in a single well.
