摘　　要：酸化压裂已成为目前极为重要的储层改造手段,分段改造技术能提高储层动用程度、增大储层泄流面积,提高油气藏的开发效果。针对超深水平井,探讨了不同储层类型下的酸压改造工艺,使得改造更具有针对性。并研发了各类酸化压裂过程的工作液体系,明确了各类工艺选择工作液的方法,制定了返排工艺,应用于实践效果良好,为类似的酸化压裂工艺提供借鉴。Acidified fracturing has become a very important means of reservoir reconstruction at present. Subsection transformation technology can improve the reservoir producing degree, increase the reservoir discharge area and improve the development effect of oil and gas reservoirs. In view of ultra deep horizontal wells, the acid fracturing process for different reservoir types was discussed. The working fluid system for all kinds of acid fracturing processes was developed, and the method of selecting working fluids for various processes was defined, and the backflow process was developed. The paper can provide some reference for similar acidizing fracturing projects.
