缝洞型碳酸盐岩油藏动态储量计算方法研究

Study on Calculation Method of Dynamic Reserves of Fracture-Cavity Carbonate Reservoir

摘要: 缝洞型碳酸盐岩油藏由于储集体空间展布多样性和内部缝洞结构的复杂性，导致该类型油藏不同于常规砂岩的层状油藏。常规油藏的储量计算方法并不适用于缝洞型油藏，这是由于储集体内部复杂的结构导致常规方法的参数选取存在一定困难。因此，有必要筛选适合缝洞型油藏计算的动态储量方法，对于指导油井生产，挖掘油藏剩余潜力，有很重要的指导意义。

Abstract: Due to the diversity of reservoir distribution and the complexity of internal fracture-cavity struc-tures, fracture-cavity carbonate reservoirs are different from conventional sandstone layered reservoirs. The reserve calculation method of conventional reservoirs is not suitable for frac-ture-cavity reservoirs. This is due to the difficulty in selecting the parameters of conventional methods due to the complex structure inside the reservoirs. Therefore, it is necessary to screen the dynamic reserve method suitable for the calculation of fracture-cavity reservoirs, which is of great guiding significance for guiding oil well production and exploiting the remaining potential of reservoirs.
