Abstract: The most serious drawback of conventional perforation completion method is formation compaction damage caused by perforation operation. Several newly developed enhanced perforation methods, such as compound perforation fractur- ing, nitrogen overbalance perforating and over pressured acidizing-Tcp joint operation, integrate perforation technology with near wellbore treatment and perform formation treatment while penetrating the formation, thus can effectively enlarge near wellobore conductivity. These methods are different in respects of operation mechanism. technology and results though they have many similarities. Suitable methods should be selected in field application according to the geologic features of operating wells and well status. Balance between treatment effects, investment and casing damage should be properly evaluated.
