带油环凝析气藏动态储量计算――以板中北高点带油环凝析气藏为例

带油环凝析气藏(凝析气顶油藏)是最复杂的油气藏类型之一,对其开采过程中的动态分析特别是动态储量的计算同样是非常复杂的。运用现代油气藏工程原理和分析方法并结合目前国内外同类油气藏开采的新方法、新技术,对板中北高点带油环凝析气藏的动态特征进行了研究。依据该油气藏的动态特征,准备了详细的参数并进行了动态储量计算。认为该研究和计算为油气藏的剩余油气分布研究和地质储量、可采储量管理提供了依据,为同类油气藏的高效开发提供了范例。

DYNAMIC RESERVES CALCULATION FOR CONDENSATED GAS RESERVOIR WITH OIL RIM :TAKING EXAMPLE OF BANZHONG NORTH HIGH POINT CONDENSATED GAS RESERVOIR WITH OIL RIM

Condensated gas reservoir with oil rim (condensated gas cap reservoir) is one of the most complex oil and gas reservoir type. It is of same complexity in development and dynamic reserve calculation. This article follows the principle and analytical method of modern oil and gas reserve engineering, in combination of new method and new technology of similar oil and gas reservoir development in China and overseas, and take the example of Banzhong north high point condensated gas reservoir to conduct the dynamic characteristic study. Detailed parameter preparation and dynamic reserve calculation is carried out basing on the special characteristic of this oil and gas reservoir. It provides the basis for residual oil and gas distribution study of the oil and gas reservoir as well as management of reserve and recoverable reserves. This analytical method has the same important directional function for the high efficient development of similar type gas and oil reservoir.
