摘要:
对海上强底水油藏水平井水驱动用储量的认识是加密调整布井的重要依据,常用的水驱曲线法大多适用于注水开发油田,对于天然水驱油藏,计算结果往往偏乐观。根据水驱油理论,结合油藏相渗表达式,建立适用于强底水油藏水平井水驱动用储量计算的新方法,计算了渤海C油田水平井水驱动用储量和动用半径。分析了该油田不同原油性质和油柱高度油藏水驱动用储量变化规律,得出不同流体性质和油柱高度储层加密井距界限,为海上强底水油藏加密调整提供依据。
Abstract:
The knowledge of water-driven reserves of horizontal wells in offshore strong bottom water reservoirs is an important basis for well placement of infill adjustment. The commonly used water-driven curve method is mostly applicable to water-injected development fields,and the calculation results are often optimistic for natural water-driven reservoirs. Based on the water-driven oil theory,and combined with the reservoir relative permeability expression,it was established a new method for calculating the water-driven reserves of horizontal wells in strong bottom water reservoirs,and calculated the water-driven reserves and active radius of horizontal wells in the Bohai C Oilfield. It is analyzed the change law of water-driven reserves in this field for different crude oil properties and oil column height reservoirs,and derived the limit of infilling well spacing for different fluid properties and oil column height reservoirs,which provides a basis for infilling adjustment in offshore strong bottom water reservoirs.
