摘　　要：针对胜利油田河口油区裂缝性灰岩油藏开发中逐渐显现的边水侵入、高含水问题进行控水技术研究。以河口L34-7块中高渗灰岩裂缝油藏为例,在系统分析含水上升规律、剩余油分布特征及堵水工艺适应性的基础上,提出“调、堵、疏”的控水思路与对策,设计相渗调节、高强度封堵及近井疏通体系。在L34-7块矿场进行了“调、堵、疏”控水工艺试验,单井增油4.8 t,含水率下降12.4%。Aiming at the problems of edge water invasion and high water cut in the development of fractured limestone reservoir in Hekou oil area of Shengli Oilfield,the water control technology is studied.According to the development characteristics of high permeability limestone fractured reservoir in block L34-7 of Hekou,the idea and countermeasures of water control technology of“regulation,plugging and drainage”is put forward to develop the system of relative permeability regulation,high-strength plugging and near well dredging,on the basis of systematic analysis of water cut rising law,distribution characteristics of remaining oil and adaptability of water plugging technology.The“regulation,plugging and drainage”water plugging technology is applied in block L34-7 for field test,the single well increases oil by 4.8 t,and the water cut decreases by 12.4%.
