通过区块分析 、试油及生产资料分析 、井口含砂监测分析、声波时差数据分析 、地层孔隙度与出砂关系的综合分析研究，进行比较准确的出砂计算并预测。
出砂指数计算
Sand-prediction technology: the sand outcome index can be accurately calculated via zone analysis, oil sample analysis, production history analysis, well-head sand monitoring, seismic data analysis, and porosity and sand correlation analysis.
出砂指数判定经验
●当出砂指数B大于2×104MPa时，在生产中油层不会出砂；
●当出砂指数B大于1.4×104MPa但小于2×104MPa时，在生产中油层轻微出砂；
●当指数B小于1.4×104MPa ，油井生产过程中出砂量较大。
极限生产压差ΔPwmax
式中：δ H……平均有效地应力 E……岩石弹性模量 v……泊松比 B0,B1……岩石的材料常数
• Sand index prediction: when sand index B greater than 2×104 MPa, there will be no sand during oil production; when B is large than 1.4×104 Mpa
but less than 2×104 MPa, few sand will present; when B is less than 1.4×104 MPa, sand is very likely to present during production.
