摘　　要：提出了使用解堵剂ＣＹ３解除油藏水堵的方法。讨论了油层中水堵（水锁）的形成。简介了解堵剂ＣＹ３的组成，测定了ＣＹ３降低油田污水和淡水表面张力的能力，通过人造和天然岩心模拟实验考察了ＣＹ３解除泥浆和油污造成的堵塞的能力。通过若干井例简介了ＣＹ３在国内许多油田应用的情况。Y3 is an aqueous solution of special surfactant(s), permeating agent, clay stabilizer, organic solvents and others. The surface activity of CY3 is studied by measuring surface tension of solution in a field produced water and an injection (fresh) water. In coreflow experiments the blockagerelieving ability of CY3 in the mud and crudecontaminated cores is shown to be fairly good(the most damage being observed in mediumpermeable cores). The field uses of CY3 in a number of oil fields are described and examplified, both for production and waterinjection wells. The creation of water blockage in reservoirs is discussed.
