摘要： 在动态数据的基础上,通过采油指数法和试井解释法确定储集层的地层系数,建立了己见水井的见水时间与打开厚度和有效厚度及其他参数的关系式,通过试算法确定有效厚度,进而确定地层的渗透率。将该方法在塔河油田缝洞型碳酸盐岩油藏中进行了应用,计算结果合理,可信度较高,具有很强的实用性。

Abstract: It is difficult to determine the parameters such as net pay thickness and permeability of fractured-vuggy carbonate reservoirs using conventional methods. This paper presents a combination method for determination of them: Based on the production and performance data, the formation factor is firstly calculated by the methods of production index and well-testing interpretation. Then the relationship between the water breakthrough time and the open/perforating thickness, net pay thickness and other related parameters is established. Following determination of the net pay thickness by trial and error method, the reservoir permeability is finally determined, which is equal to formation factor divided by net pay thickness. This combination method has been applied to the fractured-vuggy carbonate reservoirs in Tahe oil field, showing that the calculate results are reasonable and reliable, and this method is more practicable.

Key words: fractured-vuggy reservoir, net pay thickness, permeability, method
