为了解决留西油田路36断块单井液量大、高含水、地面水处理量大的问题，通过分析留西油田目标区块地质特征的适配性，重点研究同井注采技术在井下油水分离、采出系统和注入系统等技术措施在提高单井产量方面的作用效果。现场试验结果表明，同井注采技术的应用有效降低了单井产液量，降低了含水率，为油田后期开发提供了更高效的技术支撑。

In view of the problems of 36 fault block in the road of Liuxi Oilfield, such as large liquid volume in single well, high water cut and large surface water treatment capacity, through the analysis on the adaptability of geological characteristics of target blocks in Liuxi Oilfield, the research focuses on the technical measures of the same-well injection and production technology in aspects such as downhole oil-water separation, production systems and injection systems, and their effects on increasing the output of individual wells.The test results show that the application of the same-well injection and production technology has effectively reduced the liquid production of a single well and the water content, providing more efficient technical support for the later development of the oilfield.
