摘要:
根据塔北隆起奥陶系海相碳酸盐岩刻度区储层及油气富集的特殊性,对碳酸盐岩刻度区油气资源评价方法及关键参数分布模型等进行研究,并计算刻度区油气资源量。研究表明:塔北隆起奥陶系海相碳酸盐岩层系整体上可划分为风化壳岩溶型及内幕岩溶型储层;碳酸盐岩层系油气纵向上多层段叠置发育、横向连片,大面积分布,油气分布和富集程度主要受有效储层的发育控制;对刻度区油气资源评价的关键参数进行统计模拟确定的关键参数分布模型包括有效储层厚度系数模型、有效储层面积系数模型、有效储层面积丰度和有效储层体积丰度模型等;计算奥陶系风化壳型刻度区油气资源量为油1.47343×109t,气2.766×1011 m3,展现出塔里木盆地海相碳酸盐岩层系良好的勘探潜力。

Abstract:
Targeting at Ordovician carbonate reservoirs and their hydrocarbon enrichment characteristics in Tabei Uplift, this study focuses on the methodology and critical parameter distribution models for petroleum resources assessment in marine carbonate rocks. Petroleum resource of calibrated area in Ordovician carbonate reservoir was calculated, and it is shown that the Ordovician carbonate reservoir in Tabei Uplift can be divided into two types:the buried hill karst and the internal karst. Thin layers of oil and gas overlap vertically, and tend to connect laterally in the horizontal plane to form large areas of distribution. Therefore, the carbonate reservoirs are characterized by wholly oil-bearing and locally enriched oil, and the oil and gas enrichment is mainly controlled by carbonate reservoirs. By statistically analyzing petroleum geology data, critical distribution model parameters in petroleum resources assessment in marine carbonate calibrated areas were obtained. These parameters distribution models include effective thickness coefficients, effective area coefficients, effective volume resource abundance and effective area resource abundance model. Petroleum resource in the buried hill karst calibrated area was calculated based on Monte Carlo simulation using effective volume resource abundance and effective area resource abundance. The results show about 1.47343billion tons of oil and about 276.6billion cubic meters gas deposits, suggesting great exploration potential in marine carbonate rocks in Tarim Basin.
