Abstract

The invention discloses a coiled tubing tool set with cable perforations. The coiled tubing tool set comprises coiled tubing, a coiled tubing joint and a logging tool string or a perforation tool set. A cable is arranged in the coiled tubing. According to the coiled tubing tool set with the cable perforations, the structure of combining the coiled tubing and the logging tool string or the perforation tool set is adopted, and on the one hand, due to the characteristic that the coiled tubing is high in strength, toughness and loading capacity to work under pressure, the perforation requirements for highly-deviated wells and horizontal wells can be met, and the application range is wider; on the other hand, the coiled tubing can continuously work, work time is short, and efficiency is high. Meanwhile, due to production under pressure, a press does not need to be introduced, and the overall equipment occupied area is small. Therefore, through the coiled tubing, the cost of a work well is lowered, and economic benefits are improved. The invention further discloses a coiled tubing technology with cable perforations adopting the coiled tubing tool set with the cable perforations.

Description

technical field [0001] The present invention relates to the technical field of oil field perforation, more specifically, relates to a coiled tubing and cable perforating tool combination, and also relates to a coiled tubing and cable perforating process using the above-mentioned coiled tubing and cable perforating tool combination. Background technique [0002] As a common oilfield process, perforation refers to the process of using special perforating tools to penetrate the casing and cement sheath of the oil and gas layer and penetrate into the oil and gas layer to connect the wellbore with the formation and achieve the purpose of oil and gas flowing into the wellbore. [0003] At present, there are mainly two kinds of technological methods adopted in the field of oil field perforation at home and abroad, one is tubing transmission perforation, and the other is cable transmission perforation. [0004] Among them, the oil pipe transmission perforation process is to use the ...
