【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。
[Abstract]:In Halahatang oil seam water general and difficult to control such wells hole type reservoir development process, combined with the static dynamic characteristics of single well, discusses the characteristic of water producing oil and Halahatang formation mechanism. By the analysis, effects of reservoir characteristics and changeable, the formation of a variety of types of water. Among them, moving type formation mechanism for water wells: containing multiple sets of reservoir, seal water breakthrough along the non main layer, because the output channel stability, water fluctuation; water slowly rising fast type formation mechanism: producing reservoir is relatively homogeneous, the formation water breakthrough gradually increased the formation water output channel and phase the increase of permeability, water continued to rise; the sudden rise in water type formation mechanism for producing layers in vertical heterogeneity of formation water along the main channel of water breakthrough caused by sudden rise. (ladder) is proposed for different reservoir characteristics and mechanism of water The corresponding countermeasures of water control and water control are made, and the effect is obvious.
