Application and Analysis on Sand Control Technique for Unconsolidated Sandstone Formation

SUN Dexu


For unconsolidated sandstone formation, sand control problem is very important. Packing sand control materials into unconsolidated sandstone is a good idea to improving the flow conditions and stabilizing sand of down hole formation. Some application and analysis on sand control technique for unconsolidated sandstone formation are introduced in this paper. A simplified model for sand control material’s application has established. Some sensitivity of prediction and production-increasing effect are analyzed. Good conclusions are found. This technique is fit for light oil reservoir. The ratio of water reducing will decrease with the thickness of sand control materials decreasing and the oil viscosity increasing.
Key words: Sand control materials; Application effect; Simplified model


Sand control materials; Application effect; Simplified model
