| 摘 要： | 由于水平井的测井环境完全不同于直井,因此直井中所建立的裂缝型储层的双侧向测井响应模型、解释方法以及特征规律不适用于水平井。采用三维有限元数值模拟方法,分别对水平井中碳酸盐岩裂缝型储层的双侧向测井响应与裂缝孔隙度、裂缝中流体电阻率、基岩电阻率、裂缝倾角以及泥浆侵入半径等的关系作了正演计算与分析,并总结了水平井中碳酸盐岩裂缝型储层的双侧向测井响应变化规律。该研究成果对水平井中碳酸盐岩裂缝型储层的测井解释具有一定的参考价值。

| Abstract: | Because of the different environments in the horizontal well,the model,interpretation method and rule of dual laterolog response in vertical well are not suitable for horizontal well.Based on 3D finite element numerical simulation,the relations of the dual laterolog response with fracture porosity,fluid resistivity in fractures,base rock resistivity,fracture dip and mud invasion radius of carbonate fracture reservoirs in horizontal well were analyzed,and the alternation rule of the dual laterolog response of carbonate fracture reservoirs in horizontal well was summarized. |
