Abstract

High energy gas fracture (HEGF) has been one of central measures used to increase production and effusion in low permeability reservoirs. But there are some problems of this technology. One of them is that large number of toxic and harmful gases caused by it will trigger severe CO poisoning events. In this paper, the formation-gathering rule and countermeasures of CO for HFGF were studied across-the-board in low permeability reservoirs. The study showed that the primary reasons to produce CO are HEGF itself and that high temperature gases for HEGF reacted with associated gas and oil. At the same time, the formation mechanism of CO was illuminated. The study was of great theoretical value to prevent CO in effect for low permeability reservoirs, and was of great guiding significance for the rational development of similar oilfields.
