目前,国内的许多油田生产井都在使用分层合采技术进行原油开采,但是该项技术在实际应用中却时常出现采油量不升反降的现象,究其原因,是由于油井在开采过程中上下油层相互干扰所致。为此,我们需要从技术手段入手对其进行技术改进。本文以分层采油工艺中的最重要的一项技术——单泵分采工艺为题,通过对该项技术的分析和改进,解决上部油层进液控制及放大下部油层生产压差的问题,从而为分层采油技术的进行贡献自己的绵薄之力。 At present, many domestic oilfield production wells are using the stratified mining technology for crude oil exploration, but the technology in practice often appear in the amount of oil production increases and decreases, the reason is due to the well in the mining process Up and down the oil layer due to mutual interference. To this end, we need to start from the technical means to make technical improvements. In this paper, the most important one of the stratified oil production technology - single pump sub-mining process for the title, through the analysis and improvement of the technology to solve the upper reservoir into the liquid control and enlarge the production pressure difference of the lower reservoir, Thus contributing to their own modest production of stratified oil production technology.
