有杆泵预防出砂优化方法

Optimization Method of Sucker Rod Pump Design for Sand Control

使用动态射孔完井出砂预测模型,对产量与地层出砂之间的关系进行深入研究,建立了一整套可预防出砂的采油方案设计方法,该方法可以根据井射孔段附近的地质条件以及流体物性条件下得出该井在不出砂前提下的产量取值范围,并由此进行不出砂时的抽汲参数优化设计。通过实例计算表明了在对潜在出砂井的设计中,限制产量对防止油井出砂确实具有重要意义,该设计方法对疏松砂岩油藏射孔完井井型的采油方案优化设计具有一定的指导意义。

was engaged A intensive research of the relationship between the producing rate and formation sand production A new optimaization method of beam pump design for sand control is established. In this method, a range of production which can aviod sand inflow is taken and an optimization of parameters is be done. Through an- alyzing real well, a conclusion is draw that limitied production is necessary to control sand. There is some directive sense for production engineer to formulate production scheme about the kind of the gun perforated completion well in unconsolidated sandstone reservoir.
