摘要
为提高高酸性气田A1区块水平井的产能,在气藏地质研究的基础上,结合A1区块开发方案,开展了水平井投产完井方式、射孔参数优化、酸化技术研究,并针对水平井井身结构的特点,确定了以分段酸化为主的提高单井产能技术措施。形成一套适合A1区块提高水平井单井产能的工程技术,为A1区块水平井的安全高效开发提供有力的技术保障,可在同类油藏中推广应用。
On the basis of the geological study on the gas reservoir of block A1 in high-acid gas field,and referring to the relevant development program,production technologies used in horizontal wells such as well completion system,perforation parameters op-timization and acidization have been studied in this paper.On account of the characteristics of the horizontal well configuration,the segregated acid fracture has been determined as the main stimulation technology for individual well.And an unique technology system has been developed for improving the horizontal well productivity in block A1.
