摘　　要：干热岩资源开发是绿色能源开发的重要方向,为了勘查验证SB盆地某凸起寒武系观音台组与炮台山组干热岩储层,部署了该区首口勘查验证井SR1井,完井后采用油管传输射孔作业打通套管与储层,施工使用超高温器材、GR+CCL组合校深、压力起爆技术,该实例证明油管传输射孔作业方法适用于此类干热岩地热井开发,技术要求具有较好的普适性推广价值。逆向研究该干热井射孔施工实例,评价所获得的实践经验和已验证的合适的作业方法,能为国内同行提供借鉴,助力干热岩地热开发。The development of hot dry rock resources is a significant direction for green energy exploration.To investigate and verify the hot dry rock reservoirs in the Cambrian Guanyintai Formation and Paotaishan Formation of a certain uplift in the SB Basin,the first exploration well,SR1,was drilled in the area.After completion,the tubing-conveyed perforation was employed to establish a connection between the casing and the reservoir.Ultra-high temperature resistance equipment,GR+CCL depth correction,and pressure detonation techniques were utilized during the operation.This case demonstrates that the tubing-conveyed perforation technique is suitable for such hot dry rock geothermal well development,with the technical requirements offering good universal value for wider application.By reverse-analyzing the perforation of this hot dry well,evaluating the accumulated practical experience and validated operational methods,insights can be provided to domestic peers,aiding in the development of hot dry rock geothermal resources.
