Solid-phase-free gel plugging method

The invention relates to the technical field of oil and gas field development, in particular to a solid-free gel plugging method, which comprises the following steps of: arranging a well site according to site conditions, mounting a pressure-bearing platform and squeezing equipment at a wellhead, detecting an underground leakage point, determining leakage point information, configuring solid-free gel, delivering the configured solid-free gel to the leakage point, and waiting for solidification. According to the characteristics that solid-free gel is excellent in bonding performance, high in plugging capacity and not mixed with water, oil and drilling fluid, the solid-free gel permeates into cracks and microcracks such as strata, cement rings and casing pipe screw threads, plugging of leakage points is completed, the construction difficulty is reduced, and the plugging effect is improved. 本发明涉及油气田开发技术领域，具体涉及一种无固相凝胶封堵方法，根据现场情况进行井场布置，在井口安装承压平台和挤注设备，对井下漏点进行检测，确定漏点信息，配置无固相凝胶，并将配置后的无固相凝胶投送至漏点，等待凝固，凝固后进行试压，试压合格后结束作业
