曙一区兴隆台的油层属于典型的疏松砂岩超稠油性质的油藏,其成份主要是中细砂岩,稠油胶结方式是稍显疏松的方式,存在较严重的油井出砂现象.从而产生套坏的情况,对油井的正常生产造成极大的影响。本文对于科学消除油井出砂现象的途径进行了探索,分析了从钻井至射孔至生产一系列完整的油井防砂技术手段。通过生产实践验证,这种防砂技术手段可以在很大程度上消除油井出砂技术难题,将给其他同类型油藏的开发和生产带来积极的借鉴作用。
The Xinglongtai oilfield in Shuyi District belongs to a typical ultra-heavy oil reservoir of unconsolidated sandstone, and its composition is mainly medium and fine sandstone. The cementing way of heavy oil is a slightly loose way with serious phenomenon of oil sands sanding. Set of bad conditions, the normal production of oil wells have a tremendous impact. This paper explores the ways of eliminating oil sands scientifically and analyzes a series of complete sand control technologies from drilling to perforation to production. Through the production practice verification, this kind of sand control technology can largely eliminate the technical problems of oil well sand production, and will bring a positive reference to the development and production of other similar reservoirs.
