针对目前国内小井眼的防砂及层段封隔,研究开发了一种新型封隔器。该工具主要由双液缸座封机构、丢手机构、密封机构、自锁机构卡瓦锚定机构组成,具有留井内通径大、可验封、解决了小井眼封隔器由于坐封力不够导致密封和悬挂力不足的问题。关键部位的理论计算和室内试验表明:该工具综合技术性能可靠,能够满足侧钻小井眼的防砂悬挂和分层封隔的要求。
In view of the current domestic slimhole sand control and interval sealing, a new type of packer has been developed. The tool is mainly composed of a double cylinder seat sealing mechanism, a throwing mechanism, a sealing mechanism and a self-locking mechanism with a slips anchoring mechanism. The utility model has the advantages of large diameter of the well in the well, Insufficient sealing and suspension problems caused by inadequate. The theoretical calculation and laboratory tests of the key parts show that the comprehensive technical performance of the tool is reliable and can meet the requirements of sand control suspension and stratified packings for the sidetracking slim hole.
