在薄层油藏开发过程中,油井纵向上大都穿越多个油层,而在油藏合采开发方案决策中,多层油藏合采层位组合主要基于开发油井时的层系划分原则,并没有对多层油藏开采中多层合采的划分方法进行系统、定量的研究,而研究多层油藏合采和分采的技术对策对划分薄层油藏的开发层系和确定单井采油方式具有明显的工程意义。实例分析表明,明确合采层间干扰因素及干扰程度,确定合理的技术对策,可指导现场工程人员科学、高效、迅捷地开发此类特殊油藏。
In the process of thin-layer reservoir development, most of the oil wells pass through a number of oil layers in the vertical direction. In the decision of joint development and exploitation scheme of oil and gas reservoirs, the multi-layer reservoir combination is mainly based on the principle of stratification when developing oil wells There is no systematic and quantitative research on the method of multi-layer and multi-layer mining in multi-layer reservoir exploitation, and the technical measures to study the multi-layer reservoir combined mining and sub-mining. Oil production has obvious engineering significance. The case study shows that clear inter-layer interference factors and interference levels, to determine a reasonable technical countermeasures can guide field engineers to develop such special reservoirs scientifically, efficiently and swiftly.
