基于FORWARD平台的碳酸盐岩储层测井评价系统的开发与应用

Development and Application of Carbonate Reservoir Logging Evaluation System Based on FORWARD Software

碳酸盐岩裂缝性储层以其自身独有的孔隙空间结构而区别于孔隙性砂岩储层。它的低孔、各向异性、非均质性 3大特点给测井评价带来了多解性、模糊性、不确定性 ,使碳酸盐岩裂缝性储层测井评价成为一个相当棘手的难题。基于FORWARD平台 ,利用WellBase软件开发工具包SDK开发了一套碳酸盐岩储层测井评价软件系统 ,将测井资料与岩心、录井、试油等地质资料相结合 ,编制了粘土分析、储层参数精细评价、横波估算、岩石力学参数计算、裂缝综合评价、地层应力分析、有效厚度划分、成果输出等模块 ,实现了复杂碳酸盐岩储层测井评价人机交互解释。

The carbonate fractured reservoir is different from porous sand reservoir with its own unique pore space structure. The three characteristics, e.g., low-porosity, anisotropy, heterogeneity, result in nonuniqueness, fuzziness and uncertainties in the logging evaluation so that it is difficult to evaluate the complex carbonate fractured reservoir by using log data. Now we use the SDK software package of Wellbase system to develop a set of carbonate reservoir log data evaluation system on the basis of FORWARD platform, and integrate core data, oil test data and mud logging data with log data and compile various modules, such as clay analysis module, fine reservoir parameters evaluation module, shear wave evaluation module, rock mechanics parameters calculation module, synthetic fracture evaluation module, stress analysis module, net pay zonation module and interpretation results output, etc., realizing interactive interpretation in the complex carbonate reservoir evaluation.
