微生物吞吐增产渗流规律和预测方法研究

Study on filtering flow theory and the prediction method about oil increment through huff and puff of oil wells

由于理论的缺乏和认识的不足,微生物呑吐增产预测只局限于经验方法,缺少对这一问题规律性的认识。为此,在吞吐增产实践经验总结和认识的基础上,通过对微生物吞吐的渗流机理的分析,根据质量传输流体力学、化学动力学、物质平衡原理,系统的建立了吞吐渗流数学模型和增产预测模型。结合现场实践建立了相应的优化决策方法,从而系统地刻画了油井吞吐增产预测这一难题,为今后吞吐增产研究和现场应用提供了理论基础。

According to the oil increment practical experience and knowledge about huff and puff, and the analysis of filtering flow mechanisms for microbe huff and puff, the mathematical mode for the filtering flow of huff and puff and the oil increment prediction model are built systematically based on mass transmission hydromechnics theory, chemical kinetics and material equilibrium principle. The relative optimization decision method is established based on field practice, thereby the problem about huff and puff production increment of producers is described, and the study provides further research on huff and puff production increment and the field application with theoretical background.
