中东地区裂缝孔隙型碳酸盐岩油气藏原始地质储量评估方法研究
Evaluation of original oil in-place of fracture pore type of carbonate rock oil-gas reservoir in the Middle East
摘要
Abstract
The complex geological structures and reservoirs near the Zagros fold belt in the Middle East present significant challenges for accurately determining the reservoir types,sizes and hydrocarbon potential in carbonate rock reservoirs,thereby affecting the precise estimation of oil-gas reserves and compromising the reliability of resource evaluation in the area.Taking S Oilfield for example,this paper demonstrates an integrated multi-information evaluation technique and geological reserve estimation method for fracture pore type of carbonate rock reservoirs in the area,namely the quantitative evaluation of dual-media reservoir space through core analysis,well logging interpretation,and geophysical analysis.Combined with dynamic logging data,the key evaluation indexes suitable for the carbonate rock reservoirs are optimized,mainly fracture porosity and reservoir thickness.Then the seismic attributes are employed to predict the planar distribution of fracture-developed and fracture-underdeveloped reservoirs.According to the distribution range,the physical parameters of reservoirs in different zones are statistically analyzed.Finally,the volumetric method is applied to separately estimate geological reserves in fracture reservoir and matrix reservoir,which are integrated into the original oil in place(OOIP)of the whole oilfield.关键词
