渤海油田水平井产量占到总产量的40%左右，水平井控水、稳产和增产是“渤海油田3000万吨持续稳产”的关键。针对水平生产井含水上升快、吸水和产出不均匀、注采井组优势渗流通道封堵困难、传统的调驱效果不理想等问题，提出水平注水井平衡注水工艺技术，克服了传统水平井笼统调驱针对性不足的缺点，实现了渤海高含水油田水平井注水平衡开发和精细调驱的目的，应用效果良好，是提高海上油田水平井采收率的一种创新技术。
Bohai Oilfield was 40% developed by horizontal wells. In order to maintain steady production of 30 million tons in Bohai Oilfield, the water control, steady and production of horizontal wells are very important components. Aiming at solving the problems such as rapid rise of water content of horizontal production wells, uneven water absorption and output of horizontal wells, difficulty of advantage seepage channel plugging of horizontal injection and mining well group and unsatisfactory effect of traditional horizontal wells profile control, the horizontal injection wells balanced water injection technology is proposed to overcome the shortcomings of insufficient pertinence of the traditional horizontal wells general flooding control and realize the purpose of water injection balanced development and finely profile control of horizontal wells in Bohai high water content field, which shows good application effects and is a new technique to improve the horizontal wells development of offshore oilfield.
