通过对蒸汽驱波及规律研究手段、方法的总结,归纳出以下主要研究思路:(1)建立蒸汽带及热水带的波及界限;(2)建立纵向动用状况评价方法,反映油藏纵向汽驱动用状况;(3)建立蒸汽流向分析法,确定单井组优势方向及生产井受效方向;(4)数模跟踪研究纵向主力动用层;(5)蒸汽波及体积计算,确定油藏动用程度。通过上述方法研究,可以得出以下认识:(1)蒸汽波及规律具有五种主要模式;(2)蒸汽在时间和空间上的变化具有规律性;(3)可以量化出蒸汽在平面和纵向上的扩展速度。因此,开展蒸汽驱波及规律研究方法研究,可以为蒸汽驱提供一种研究模式,能更全方位地分析蒸汽驱所处的开发状况,为实时调整提供理论依据。
Through summarizing the means and methods of the research on the law and method of steam wave driving, the following main research ideas are summarized: (1) to establish the boundary of the steam band and the hot water zone; (2) to establish the evaluation method of the longitudinal utilization condition, which reflects the longitudinal steam drive (3) establishing a steam flow analysis method to determine the dominant direction of the single well group and the direction of production well acceptance; (4) tracking the main active use layer by digital-analogue tracking; (5) calculating the volume of steam and volume and determining the degree of utilization of the reservoir . Through the study of the above methods, we can draw the following conclusions: (1) There are five main modes of steam wave law; (2) The steam has regularity in time and space; (3) The steam can be quantified in the plane and in the vertical direction The speed of expansion. Therefore, carrying out research on steam drive and law research methods can provide a research mode for steam flooding, analyze the development status of steam flooding more comprehensively, and provide a theoretical basis for real-time adjustment.
