井下封隔器的密封技术对于油田注水开发具有重要的影响。如果封隔器的密封效果不严,就会影响分层注水质量,加剧层间矛盾。同时,由于传统的封隔器在水井验封过程中存在一些不足之处,不仅容易出现误判和难以判定的情况,而且反复测试,增减了工作强度,也相应的提高了测试成本,因此需要采用新的技术方法对于原有的验封技术和测试仪器进行改进。故而,本文主要通过对于分层注水井封隔器验封新技术的应用进行研究,结合具体的实践情况,提出一些有益的意见和建议,从而进一步提高验封新技术的应用效果。 Downhole packer sealing technology for oilfield water injection has an important impact. If the packer sealing effect is not strict, it will affect the quality of stratified water injection, exacerbating the conflict between layers. At the same time, the traditional packer has some shortcomings in the process of well inspection, which is not only prone to misjudgment and difficult to judge, but also repeated testing, increase and decrease the work intensity and correspondingly increase the testing cost Need to adopt new technical methods for the original sealing technology and test equipment to be improved. Therefore, this paper mainly studies the application of the new technology of packer seal inspection in stratified injection wells, and puts forward some useful opinions and suggestions based on the actual practice so as to further improve the application effect of the new seal inspection technology.
