摘要/Abstract

摘要： 针对哈拉哈塘油田缝洞型油藏开发过程中油井见水普遍且治理难度大等问题，结合单井动静态特征，探讨了哈拉哈塘油田的产水特征及形成机理。分析认为，受产层段储层特征多变的影响，形成了多种含水类型。其中，含水波动型形成机理为：井段有多套产层，封存水沿非主力层突破，由于产出通道稳定，含水波动变化；含水缓慢-快速上升型形成机理为：产层段储层相对均质，地层水突破后随地层水产出通道的逐渐增多及相渗的增大，含水持续上升；含水突然上升型形成机理为：产层段纵向上非均质性严重，地层水沿主产通道突破，致含水突然（阶梯）上升。针对不同油藏特征及出水机理提出了相应的控水治水对策，效果明显。

关键词: 哈拉哈塘, 缝洞型油藏, 产水机理, 控水治水

Abstract: Water breakthrough becomes common and it is difficult to solve this problem in fractured vuggy carbonate reservoirs, such as the one in Halahatang Oilfield. Based on well data characteristics, we conducted a study on the characteristics and formation mechanisms of water producing to solve the problem. Analysis shows that different water cut shapes represent different mechanisms that are related to characteristics of production intervals. Fluctuant water production includes sets of reservoirs, and water fluctuates in the non-main production layers in the form of pent-up water. Slow-rapid increase in water cuts form in relatively homogeneous producing intervals, because of the increase in output channels and relative permeability after the water coning breaks through. A sudden increase in water cut forms when producing intervals are seriously heterogenous, and the water breaks through via main production channels. According to the characteristics of reservoirs and water producing mechanisms, measures for water control are proposed, which prove to be effective and can be widely applied.

Key words: Halahatang, fractured-vuggy reservoirs, mechanism of water producing, water controlling
