摘　　要：TAMBOCOCHA油田主力油层M1层产量高(平均产油量为300~800 m^(3)/d),油水活跃,采用旋转尾管固井,φ215.9 mm井眼下φ177.8 mm尾管,环空间隙窄,后期完井试采措施的开展及产能建设对底水油藏固井质量要求高。为此开展复合酸性前置液体系、强触变微膨胀胶乳水泥浆体系及相应固井工艺技术措施研究,并通过33口井的现场试验,形成了厄瓜多尔TAMBOCOCHA油田油水活跃油藏固井技术,提高了该油田底水油藏固井封固质量,并对国内底水油藏及高含水调整井防水窜固井具有一定的借鉴意义。The main oil layer M1 of Tambococha oilfield has high production(average oil production is 300~800 m^(3)/d)and strong activity on oil and water.When rotary liner is used for cementing,and the space gap of cementing annulus is narrow(φ177.8 mm liner φ215 mm well head,with a clearance of 19 mm).The development of well completion and production test measures in later stage and productivity construction have high standards for cementing quality of bottom water reservoir.Therefore,the research on composite acid preflush system,strong thixotropic expansion latex cement slurry system and corresponding cementing technology measures are carried out.Through the field test of 33 wells,the cementing technology of oil-water active reservoir in Tambococha oilfield in Ecuador is formed,and the cementing quality of bottom water reservoir in this oilfield is improved.It has a good guidance for waterproof channeling cementing of domestic bottom water reservoirs and high water cut adjustment wells.
