摘要
喇萨杏油田进入特高含水期，水油比急剧上升，控水难度大。为了有效控制油田含水上升速度、提高油田开发效果，采用结构分析、贡献值分析的方法，提出结构含水和结构系数的概念，研究了影响油田含水上升速度的主要因素，分析了喇萨杏油田开发过程中采取的结构调整方式以及打加密井、聚合物驱油、压裂、换泵、堵水、关井等调整措施对控制含水上升的作用。探讨了进一步控水的可行性，研究了深化结构调整技术以及各种控水措施的潜力和效果，通过数值模拟计算，预测了不同情况下喇萨杏油田到2010年的含水变化趋势，预计到2010年，喇萨杏油田通过技术攻关，含水可控制到93．12％。
When entering into the period of extra-high water cut in Lasaxing Oilfields, water and oil rise quickly, so the water control difficulty become rather serious. In order to effectively control water cut rise speed and enhance oilfield development effects, by adopting structural analysis and analyzing method of contribution values, this paper proposes the concepts of structural water cut and structural factor, explores the main influence factors on water cut rise speed, and analyzes the structural adjustment mode adapted in the oilfield development and the actions of adjusting measures （ such as infilling well, polymer flooding, fracturing, pump change, water plug, well shut - in and so on） on controlling water cut rise. The feasibility of further water control is discussed, and moreover the structural adjustment techniques and the potentials and effects of all kinds of water control methods are＇deeply stud- ied. With the help of numerical simulation calculation, water cut change trend until 2010 in Lasaxing Oilfield under different conditions has been predicted： through technical innovations, the water cut will be controlled to 93.12% in 2010.
