本文针对喇嘛甸油田已进入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Y341-114-90/15逐级解封堵水封隔器来避免该现象的发生,该技术研究成功后,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,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 oilfield has entered the stage of extra-high water cut mining stage, in order to subdivide injection, the packer used in more and more stages, but in the actual application of the process of unwinding, easy to overhaul phenomenon, Development of Y341-114-90 / 15 step by step to seal off the water packer to avoid the occurrence of the phenomenon, the successful study of the technology, through the development and application of the technology to achieve the lifting operation when the load is small, and Can be achieved level by level closure, the oil well for the sub-injection to provide a reliable technical support, with good market applications and economic prospects.
