【摘要】 出砂已经成为影响油井产能和损害生产设备的严重问题。在油田开发阶段 ,必须认真设计与出砂有关的一些生产参数。利用弹性和弹塑性理论建立了防止油井出砂的临界井底流压计算模型 ,在此基础上利用盘 2 2 0 7井的岩性、物性和力学等参数进行了计算 ,得出该井避免出砂的安全生产压差 ,所得结果与油井生产实际相符合更多还原

【Abstract】 Sand production has become a serious problem of influencing well productivity and damaging production equipment. The parameters related to sand production must be designed carefully for oilfield development. The calculating model of critical bottomhole pressure is established for sand production controlling by using elastic and elastoplastic theory. Based on the model, the safe value of producing pressure differential of sand production controlling is calculated by using the lithological physical and mechanical parameters of Well Pan207. The result is consistent with the production.更多还原
