新型一体化树脂固砂液体系的室内研究

疏松砂岩油藏开发过程中出砂严重,防砂技术成为维持疏松砂岩油藏油井长期正常生产的主要措施之一。针对海上疏松砂岩稠油油藏开采出砂井防砂问题,室内初步研制了新型一体化树脂固砂液体系以提高砂体胶结强度。室内研究表明,新型一体化固砂液体系具有良好的胶结固化性能,扩孔后渗透率保留率高,低温固结性能强,固结质量好,抗腐蚀性能强,能够满足油田现场的固砂作业。

Laboratory Research of the New Integrative Gel Type Resin System

Because sand flowed seriously in the process of the development of unconsolidated sand reservoir,sand control technique became one of the main measures to maintain the long-term normal production of the well in such reservoir. Laboratory preliminary developed the new integrative gel type resin system in order to improve the curing strength of sand body in view of the sand control of sandy well in unconsolidated sand heavy reservoir at sea. Such system can meet the sand consolidation work of oil field which showed many advantages in the laboratory study such as good performance of cementation solidifying,high permeability retention after borehole enlargement,strong consolidation at low temperature,consolidation of good quality,intense corrosion resistance and so on.
