通过对山东临盘油田盘二区块地质特征及生产资料的统计分析 ,研究了生产过程中油井出砂机理。结果表明 ,地层压力、生产压差以及含水率是影响油井出砂的重要因素。保持足够高的地层压力开采 ,设计合理的生产压差 ,控制产水率上升 ,能有效减少出砂 ,最终达到高产的目的 Through the statistical analysis of the geological characteristics and the means of production in Block Pan2 of Linpan Oilfield, Shandong Province, the sand production mechanism of oil well in the production process was studied. The results show that the formation pressure, production pressure and water content are important factors that affect the oil well sand production. Maintaining high enough pressure of formation pressure, designing reasonable production pressure, controlling the increase of water production rate, reducing sand production effectively and finally achieving high output
