摘要： 塔河碳酸盐岩油藏是一个与 古风化壳有关的岩溶洞穴型裂缝油藏,储集体类型复杂、多样,非均质性极强,具有三重介质流动特征,稳油控水具有相当难度。在总结2001年以来A区实施的稳油控水工作基础上,提出如下的稳油控水基本做法:油井见水前严格控制生产压差,见水后必须压锥,停喷后转抽,转抽效果不佳则尝试堵水,堵水未果采取堵、酸结合,仍然无效的无潜力井或进行侧钻,或尝试注水试验。实施这些措施后,效果明显,开发指标得到好转。

Abstract: Tahe carbonate reservoir is a fractured reservoir with karst and caves related to weathering crust. It is characterized by complex and variety of reservoir bodies, very serious heterogeneity and triple porous media flowing, which result in very difficult stable production and water control in it. Since 2001, in District A of Tahe field have taken measures for the purpose of stable production and water control (SPWC). This paper presents basic procedures for SPWC, they are, strict control of producing pressure differential prior to water breakthrough, water-coning control after water breakthrough, and pumping when unflowing;_ if pumping is not effective, water plugging will be taken, if water plugging is ineffective, combine with acid treatment, if acid treatment is unsatisfied, take sidetrack drilling or water flood test. Following these measures, obv ious effectiveness and improved production indices have been found in this reservoir.
