| 摘 要： | 油井出砂已经成为困扰疏松油藏生产的一个严重问题，科学有效地进行出砂预测对于指导油田高效开发具有重要意义。文中分析了油井生产过程中的出砂机理，给出了判断出砂的临界压降模型，进而推导出临界流量模型。该模型反映近井筒压降与地层拉伸应力和黏结力变化的关系，对制定油井合理的生产制度具有一定的指导作用。

| Abstract: | Sand production in oil well has become a serious problem for unconsolidated reservoir production.It is of great importance to scientifically and effectively predict sand production for guiding the effective production in the oilfield.This paper presents a model to determine the critical pressure drawdown based on relating the near wellbore pressure drawdown to the tensile and cohesive strength of formation by analyzing sand production mechanism.The model is profitable to make system for oil production. |
