油田进入特高含水开发后期,作为稳油控水、挖潜增效的主要工艺措施——机械堵水在油田开发中的作用尤为重要,作业队作为机械堵水工艺的主要实施者,每年要承担大量的机械堵水施工任务。根据近期根据油田细分开采的需要,封堵井段隔层厚度越来越小,最小隔层厚度已由2.0m降为0.5m以下,隔层厚度的减小给作业施工技术提出了一个难度较大的课题,为保证堵水施工任务的顺利完成,确保油田稳油控水措施的顺利实施及提高作业施工效益,我们对堵水管柱卡点深度的影响因素进行了综合分析。
Oilfield into the late development of ultra-high water-cut, as the main process of water diversion and potential efficiency-mechanical water shutoff is particularly important in the development of oilfields. As the main implementer of mechanical water shutoff process, A large number of mechanical plugging construction tasks. According to the recent needs of subdivision and recovery of oilfields, the thickness of the plugging section is getting smaller and smaller, the minimum thickness of the plugging layer is reduced from 2.0m to 0.5m, and the decrease of the thickness of the interlayer presents a difficulty for the construction technology In order to ensure the successful completion of water blockage construction tasks, ensure the smooth implementation of oil stabilization measures and improve the construction efficiency, we analyzed the factors influencing the depth of blockages.
