表面活性剂缓速酸酸压实践

塔河油田奥陶系碳酸盐岩油藏油气渗流通道主要为裂缝，油井完井后大多无产能，需要通过酸压增产改造措施，才能保证油井正常生产。在对油藏地质认识的基础上，优选酸液体系，对压裂工艺参数进行优化设计，确保在地层中形成一定长度、高导流能力的酸蚀裂缝并有效沟通储集层。表面活性剂缓速酸酸压在TK466井的成功实践，将为今后油田高效开发提供强有力的技术支持。

Acid Fracturing Practice of Surfactant Retarded Acid

Oil and gas flow through porous media mainly depend on fracture in Ordovician Carbonate reservoir of Tahe oilfield.Most of the oil wells haven't any production after completion.In order to ensure well's normal production,it's necessary to improve production of oil well through acid fracturing.This paper optimize acid fluid system and fracturing parameters on the basis of the recognition of reservoir,so as to acquire a certain length and high conductivity acid corrosion fracture in the formation and ensure it link up with reservoir effectively.The acid fracturing technology of Surfactant Retarded Acid is used successfully in well TK-466.The successfully experience will supply technique support for the development of Tahe oilfield in future.
