利用测井资料模拟小层油水分布规律

Oil-water Distribution in Thin Zone Simulated by Log Data

对于多油层、非均质注水开发油田，如何更准确地掌握剩余油的分布规律，实现油田开发后期的相对稳产，控制其递减速度就显得尤为重要。针对老君庙油田L油藏地质沉积特点，利用测井资料进行分小层模拟其油水分布规律，应用现场取得了较好的效果，社会及经济效益可观。该研究地下油藏的思想方法和实践手段对同类型的其它油田的开发具有一定的指导意义。

In medium or later phase for a sand reservoir developed by injecting water, the oil-water distribution within the reservoir becomes more and more complicated. It's important to know the distribution of retained oil,make the reservoir in relative stabie production and decelerate the decline rate of the oil production, especially for the oil field with serious inhomogencity in horizontal or vertical direction and multizone waterflooding. This paper adopts log data in thin zone to simulate the oil-water distribution for L reservoir of Lao Junmiao oil field on the basis of its geological property. Better progress has been made in practice by using this method. Social effect and obvious economic benefit is very known. The method of thought and practice has guide meaning for the sarne type oil field.
