| 摘 要： | 为解决油气开发中水平井中井眼对双侧向测井响应的影响,建立了上、中、下三层介质的水平井模型,采用三维有限元方法进行研究。数值计算结果表明,水平井眼处于目的层不同位置、不同井眼尺寸以及泥浆电阻率等都对水平井双侧向测井响应有不同程度的影响,特别是对非厚层影响更加明显。井眼尺寸越大和泥浆电阻率越高,对双侧向测井响应的影响就越严重。当目的层小于6 m时,水平井中的深、浅双侧向测井响应都不同程度地受到层厚围岩的影响;当层厚分别大于36 m和6 m时,深侧向和浅侧向测井几乎不受围岩影响;在15°的范围内,不同的井眼倾角对双侧向测井响应影响不大。

| Abstract: | Based on horizontal well modeling with 3 layers,the authors analyzed the impact of borehole on dual laterolog in the horizontal well by using the 3D Finite Element Method.The numerical simulation shows that the positions of horizontal boreholes,the various borehole sizes and mud resistivity exert obvious influences on dual laterolog response,especially in the thin bed.The larger the borehole size and mud resistivity are,the more serious the impact on dual laterolog response is.Within the thickness of 6 m,the deep and shallow laterolog response in the horizontal well varies with parameters of the shoulder bed.The shoulder bed makes little impact on the deep laterolog response beyond the thickness of 36 m and on the shallow laterolog beyond the thickness of 6 m.Within the range of 15°,the dip-angle of horizontal borehole makes little impact on the dual laterolog response. |
