摘要
介绍了油田开发中几种常用的井间示踪剂技术原理、特点及在油田的应用效果和发展趋势,阐述了井间示踪剂技术的多种用途。通过示踪剂技术可以分析油田的水驱规律,了解断层的封闭状况,验证油水井的连通情况,计算注水井在平面上各个方向的渗流速度以及油井的水淹方向,确定区块的剩余油分布等,对于进一步认识油藏的非均质性、注入水沿裂缝窜流的规律、注水方案调整以及调剖堵剂用量的确定起到了积极的指导作用,为油田的油水井调整、工艺技术措施和综合治理提供了可靠的科学依据。
An introduction is made of the principle,characteristics,results of application in oilfields,and trends of development of some inter-well tracer techonologies commonly used in oilfield development.A discussion is made of various uses of inter-well tracer technology.It can be used to analyze oilfield waterflooding performance,to learn about fault closure,to verify the interconnection of oil-water wells,to calculate the percolation flow velocity of water injection well in all horizontal directions and waterflooding direction of wells,and to determine the distribution of remaining oil in tracts.All this can help to further understand the inhomogeneity of oil reservoirs,and the regularity of interporosity flow of injected water along cracks,to adjust water-injecting plan and to determine the amount of profile control agent,thus providing reliable scientific basis for the adjustment of water injection wells,the adoption of technological measures,and comprehensive governance of oilfiels.
