摘要
为科学合理地开展储量评估以指导后期的勘探开发,避免储量评估出现较大偏差,以塔里木盆地哈拉哈塘油田某区块缝洞型碳酸盐岩油气藏为例,研究碳酸盐岩准层状油藏缝洞雕刻及储量计算方法。利用基于高精度三维地震的缝洞量化雕刻技术确定储量计算参数;利用地震反射特征的敏感属性及门槛值,结合高置信度的井震联合反演技术分别刻画洞穴型、孔洞型、裂缝型3类储集层的含油面积、有效厚度及有效孔隙度参数。依据容积法,求取不同储集层类型的储量,再由实钻井进行动态采收率的标定。该方法用于非均质性极强的缝洞型碳酸盐岩油气藏的储量计算及方案编制,可实现储量的有效动用。
To avoid big deviation in reserve estimation and make scientific and reasonable reserves to guide the exploration and development of fracture-cavity carbonate reservoirs, a new three-dimensional reservoir space description and reserve calculation method for layered, fracture-cavity carbonate reservoirs is used to calculate the reserves of X block in the Halahatang oilfield in the Tarim Basin. In the method, the reserve calculation parameters are worked out by quantitative spatial delineation based on high precision three-dimensional seismic data; the high confidence well-seismic inversion and sensitive attributes and threshold value are used jointly to delineate the oil-bearing area, effective thickness and effective porosity of the cavity, vug and fracture reservoirs. The reserves are calculated with the volumetric method, and the dynamic recovery of different types of reservoirs is calibrated by actual drilling data. This method is suitable for reserve estimation and development program making of fracture-cavity carbonate reservoirs with strong heterogeneity.
