本文针对喇嘛甸油田特高含水期开采阶段,为了细分注采,采用的封隔器级数越来越多,而在实际应用过程中出现的不解封,易上大修的现象,研制Y347-SJ/DS-114×55-120/15-(2-7/8NUE)封隔器,来避免常规封隔器不解封或解封不彻底造成的飞油管及引起井架坍塌设备损坏和人员伤亡问题。该封隔器研究成功后,通过该技术的研制及应用,达到起管作业时解封负荷较小,并能实现逐级解封的目的,为油层细分注采提供可靠的技术支撑,具有较好的市场应用和经济前景。
This paper aims at Lamadian ultra-high water cut stage mining stage, in order to subdivided injection, the packer used in the increasing number of stages, but in the actual application of the process of unwinding, easy to overhaul phenomenon, the development of Y347 -SJ / DS-114 × 55-120 / 15- (2-7 / 8NUE) packers to prevent damage to the derrick collapse equipment and personnel caused by incomplete packer unsealing or undocking Casualties. After the successful research of this packer, through the research and application of this technology, it achieves the goal of lifting unloading and taking off the seal gradually when the pipe is started, and provides reliable technical support for the subdivision and injection of oil layers. Better market applications and economic prospects.
