1引言稠油井出砂是油田油气开采过程中砂粒随流体从油层中运移出来的现象。其危害很多:会造成砂埋油层、砂堵井筒、管线及储油罐积砂,影响油井产量;产出砂造成抽油泵、柱塞等设备磨蚀,使油井停产作业,导致成本上升;造成井壁坍塌,套管变形和损坏,严重时导致油井报废。出砂引起一系列危害,既提高生产成本,又增加管理难度,因此必须采取防砂措施。防砂是指对出砂的 1 Introduction Heavy oil well sand production is the oil and gas during the sand with the fluid migration from the reservoir out of the phenomenon. It is harmful for many reasons. It will cause the sand buried oil layer, the sand blocking the wellbore, the pipeline and the storage tank sand, which will affect the oil well production. The sand produced by oil production will cause abrasion of equipments such as oil pump and plunger, Wall collapse, casing deformation and damage, resulting in serious oil wells scrapped. Sand causes a series of hazards, both to increase production costs, but also increase the management difficulty, it is necessary to take sand control measures. Sand is sand on the sand
