摘要
由于低渗油藏注不进水或注水开发效果不好,采用气驱、特别是天然气驱来改善开发效果是最好的选择,但天然气驱只适合于特定的油藏,对油藏进行适应性筛选评价可提高天然气驱的成功率和经济效益。本文在分析影响天然气驱的客观因素的基础上,利用数值模拟技术对各影响因素进一步量化,将天然气驱目标区块的定性分析转为半定量化,提高了试验目标区块选择的有效性,为天然气驱试验区的选择提供了有利工具。在分析影响天然气驱采收率的主要客观因素基础上,结合构造、气顶、边水等因素,对中原油田的62个低渗油藏进行计算,筛选出一批适合天然气驱的目标单元,收到较好效果。
As the low-permeability reservoir water or water injection does not effect the development of poor use of gas drive, especially natural gas drive to improve the effectiveness of development is the best choice, but the drive is only suitable for natural gas in a reservoir, the reservoir of adaptation Screening and evaluation of the drive to improve the success rate of natural gas and economic benefits. Based on the analysis of the impact of natural gas drive on the basis of objective factors, the use of numerical simulation technology to further quantify the impact of factors that will drive natural gas blocks the goal of qualitative analysis and quantitative and a half to raise the test of the validity of the choice of the target block For the gas-drive test zone has provided a powerful tool to choose. In analyzing the impact of a major natural gas drive recovery on the basis of objective factors, combined with the construction, gas cap, while factors such as water, the Zhongyuan Oil Field of 62 low-permeability reservoirs are calculated, selected for a number of natural gas flooding the target cell ,received better results.
