摘　　要：海上油田水平井出水受地质、工程、开采等因素影响,见水模式复杂,且多为筛管防砂完井,筛管外存在环空,筛管窜流严重,找堵水工具存在起下风险大、措施成本高、找堵水准确率低的问题。为解决这些问题,通过研究设计具有八挡位流量大小开度的机械智能液控测调工作筒,实现了产层分段流量监测与控制。同时研究将高分子媒介作为基底(骨架),将缓释型示踪剂包裹在内的出水监测法,实现了产层各分段油水产出情况分析。通过现场应用实现传统找堵水与开发生产控水完井一体化,在降低作业成本的同时,对海上油田开发找水/控水具有重要意义,同时有助于油藏深入认识油层出水规律及优化产液制度管理。The water production of horizontal wells in offshore oilfields is affected by geological,engineering and mining factors,and the water breakthrough mode is complex.Most of them are completed by screen tube sand control,and there is an annulus outside the screen tube.The screen tube flow is severe,and the water plugging tools have problems such as high risk of lifting,high cost of measures,and low accuracy of water plugging.In order to solve these problems,a mechanical intelligent hydraulic control measuring and adjusting working cylinder with eight levels of flow rate opening was designed to achieve segmented flow monitoring and control of the production layer.At the same time,the water monitoring method with polymer media as the substrate(skeleton),encapsulating slow-release tracers was studied to analyze the oil-water production in each section of the production layer.The integration of traditional water plugging and water control completion in development and production is of great significance for horizontal well water finding/control in offshore oilfields,while reducing offshore operating costs.It also helps to deepen the understanding of water production laws in oil reservoirs and optimize the management of liquid production systems.
