摘　　要：为进一步提高冀东浅层油藏的开发效果,需要进行出砂临界压差预测研究.通过储层岩芯试验,得到储层岩石强度,分析认为冀东油田储层段岩芯单轴抗压强度普遍较低,绝大多数在5 MPa以下,属于典型的弱固结砂岩储层,储层出砂的可能性较大.结合孔隙度经验模式,确定G114-6井储层段临界出砂生产压差在l MPa以下；LN2-6井储层段临界出砂生产压差在0.1～2.5 MPa之间.In order to further improve the development effect of Jidong Oilfield shallow reservoir, it needs to predict sanding critical drawdown pressure. Reservoir rock strength is obtained by core experiments, through analysis knowing that reservoir core uniaxial compressive strength is generally low, the vast majority is under 5 MPa, belongs to the typical weakly consolidated sandstone reservoir, and it is more likely sanding. Combined with porosity experience mode, determining G 114-6 well reservoir section critical drawdown pressure is under 1 MPa and LN2-6 well is between 0. 1 - 2.5 MPa.
