【摘要】：低产井治理是一项伴随油田建产、开发全过程的主要技术工作,随着油田开发时间的延长,油井产量下降,油井低产成为制约姬塬油田提高整体产量的最主要因素。本文通过研究油井周围压力、含水分布及地应力变化,对低产井进行分类,一方面结合油井周围复杂多缝形成的机理与条件,通过多种工艺的复合联作,形成复杂多缝系统,为低产井的增产与稳产提供技术支撑,最终形成以增大油层泄油面积为目的的一系列多缝体积改造技术。
[Abstract]:The treatment of low production wells is a main technical work in the whole process of oilfield construction and development. With the extension of oilfield development time, the oil well production decreases, and the oil well low production becomes the most important factor restricting the overall production in Jiyuan Oilfield. In this paper, by studying the pressure, distribution of water cut and variation of in-situ stress around oil wells, the low production wells are classified. On the one hand, a complex multi-fracture system is formed by combining the mechanism and conditions of the formation of complex multiple fractures around the wells and by the combination of various processes. It provides technical support for increasing production and stable production of low production wells, and finally forms a series of multi-fracture volume modification technologies aimed at increasing the oil discharge area of reservoir.
