摘要
注水管柱在工作过程中受井口压力、注入量、井深、井温等的影响 ,会引起伸缩蠕动 ,导致封隔器解封或失效 ,影响分层注水的水驱效果。为了保障注水管柱有效合理地工作 ,应准确地掌握注水管柱的应力和轴向变形 ,合理地计算注水管柱的伸缩力和伸长量 ,为采取有效合理地预防措施 ,提供理论依据。
For the influence of wellhead pressure,water injection rate,well depth and well temperature on water injection string during operation,the string is caused elastic creep.These factors result in packer effectiveness and influence the water driving effect of separate layer water injection. In order to ensure water injection string work normally,the stress and axial delformation of water injection string should be grasped accurately.Elastic force and elongation rate are calculated,which provide theoretical proof for the corresponding preventive measures.
