Zusammenfassung:The invention relates to downhole testing, and particularly relates to an oil pipe dragging type horizontal well rapid segmented testing system and an implementation method. The method comprises the following steps that 1, an oil pipe control tool string is put in position; 2, after the oil pipe control tool string reaches the position, an upper electric control packer and a lower electric control packer start to be set; 3, a liquid drainage swab is put into an oil pipe to extract liquid, and a multi-parameter tester and wellhead metering equipment test the to-be-tested liquid while extraction is conducted; and 4, after testing is completed, deblocking is conducted, then the oil pipe control tool string reaches the next to-be-tested position, and the steps are repeated till testing of all layer sections is completed. According to the oil pipe dragging type horizontal well rapid segmented testing system and the implementation method, the mode that the tool string carries a battery pack is adopted, cable puttin
