摘　　要：针对海上低孔低渗油气井储层改造的特点,从降低施工风险、节约作业成本、减小储层污染和提高完井时效等方面,开展了开发井和探井的压裂管柱优化设计,所设计的开发井压裂一体化管柱和压采复合型管柱以及探井射孔-测试-压裂一体化管柱在现场得到了很好的应用,并取得了良好的效果。In view of the characteristics of low po- rosity and permeability reservoirs reconstruction in offshore oil and gas wells, we optimized the fractu- ring string design for development and exploration wells from the aspects of reducing the construction risk, saving the operation cost, protecting the res- ervoirs and improving the well completion efficien- cy, etc. The integrated string for the development wells, the composite string for the fracturing and production, and the integrated string of perfora- tion-test-fracturing for exploratory wells have been applied in the field successfully and efficiently.
