现河庄油田分层注水管柱配套模式及应用

Matching mode and application of regulating separate stratum injection string in Xianhezhuang oilfield.

针对现河庄油田分层注水管柱寿命短的问题 ,研究制定了几种完善分层技术的方案 ,主要包括锚定补偿管柱技术、国外锚瓦 (双卡瓦 )管柱技术、新型悬挂式管柱技术三大类。介绍了各类管柱技术的工作原理 ,对现场应用情况进行了分析评价 。

Aiming at the short life time of the regulating separate stratum injection string in Xianhezhuang oilfield, several improved technologies, including archoring compensating string technology, international doubleslip string technology and modern holddown string technology, are studied. The working principle of these technologies is introduced. Field application situation is evaluated. It is pointed out that the future development of the regulating separate stratum injection string technology is the holddown pressure balance string one.
