为了提高防氟井质量,保证上下隔水层的水不串通,我局研究试用了胶球(亦可称胶套)止水新工艺。胶球止水的原理是,利用橡胶的富有弹性和对水、气不渗透的特点,制成中间空、上下串通的椭园形管,套在铁井管上,随井管下在预定的止水层。 In order to improve the quality of anti-fluorine wells and ensure that the water in the upper and lower water barriers does not colluded, the Bureau has researched and tested a new process for sealing water with rubber balls (also called rubber sleeves). The principle of rubber ball sealing is to make use of the elasticity of rubber and the impermeability of water and gas to form an ellipse-shaped pipe that is hollow in the middle and is concatenated with the upper and lower strings. It is set on the iron well pipe and is scheduled under the well pipe. Water stop layer.
