四方坨子油田开发实践与认识

四方坨子油田是吉林油区西北部的一个低幅度短轴背斜油气藏油田1987年采用“顶密边疏”的300－400m井距正方形井网依靠天然能量投入开发，并相继经历了提液增油、污水回注、边密调整等几项重要的开发调整阶段。在不断的开发过程中，油田始终坚持把充分利用天然边水能量，加强油藏动态监测和剩余油分布规律研究作为工作重点，通过应用数值模拟，C／O测井、水动力监测等项新技术来对不同时期剩余油进行研究，及时指导油田的调整挖潜工作，取得了很好的开发效果。

DEVELOPMENT PRACTICE AND RECOGNITION ON SIFANGTUOZI OIL FIELD

Sifangtuozi Oil field is a slight minor axis anticline reservoir in northwest Jilin oil area. The field was put into production in 1987 with square pattern of 300 400m well space using natural energy and has experienced some adjustment periods including bailing production, produced water re injection and infilling adjustment. The focus of development is using natural marginal water energy, monitoring reservoir dynamic and studying residual oil distribution rule. Residual oil is studied through numerical simulation, C/O logging and water dynamic monitoring so as to direct the potential seeking of the oil field.
