探讨了垂直油井在绕丝防砂井出砂早期及油井大量出砂后的单相稳态流的防砂产能预测公式的推导过程、预测方法。结合现场应用情况进行验证,证明本方法是基本可靠的。
The derivation process and forecasting method of sand production capacity prediction formula of single-phase steady-state flow of vertical well in the early stage of sand production from wire-wound sand-control well and after a large amount of sand production in oil well are discussed. Combined with the field application to verify that the method is basically reliable.
