This paper introduces a new type of perforating completion technology modularization wire line perforating technology．It uses monocable to run the hanging device of the perforator to the desired depth；then the full modular perforating guns required by the perforating operations are run to the well one after another；at last，the perforating charges are detonated．With the technology，the aim of running multiple guns individually and detonating at one time is realized．Based on this technology，with a special guiding design，the wire line oriented perforating is completed．The technology is making full use of the special features of the wire line conveyed method，including less equipment，easy operation，and short job time，etc., also fulfills some functions of tubing conveyed perforating，such as underbalanced perforating in the whole well，preventing blow out，etc．In addition，in the perforation in high pressure oil and gas wells，the modular perforators can be dropped to well bottom．Thus the wells can produce directly without restriction to the high pressure oil and gas．If the down hole tools need to be pulled out，the operation can be completed with the wellhead lubricator for the tool in the well is not long．
