油井出砂是疏松砂岩油藏开采过程中常见问题之一,是困扰油田块高效开发的主要矛盾。它容易造成泵卡和砂埋生产管柱现象,不仅严重影响油井正常生产时率,更甚者致使油井无法生产,而且采出的携砂原油在集输过程中会破坏地面集油设施和输油管线,形成严重的安全环境危害和成本浪费。文章主要DW油田疏松砂岩防砂配套技术的改进与应用进行介绍。
Oil well sanding is one of the common problems in the process of unconsolidated sandstone reservoirs and is the main contradiction that plagued the efficient development of oilfield blocks. It is easy to cause the pump card and sand buried production column phenomenon, not only seriously affect the normal production rate of the well, even worse, the oil well can not be produced, and produced by carrying the crude oil in the gathering process will undermine the ground oil collection facilities and pipelines Line, forming a serious safety hazard and cost waste. This paper introduces the improvement and application of loose sandstone sand control technology in the main DW oilfield.
