水平井非平行界面下各向异性地层双侧向测井响应研究
|
摘要
双侧向测井是一种常用的获取地层电阻率的测井手段。实际测井环境中,往往由于不整合面、断层等因素的存在,使得地层上下界面不平行,水平井双侧向测井响应不能真实反映地层信息。水平井中双侧向测井响应受地层各向异性性质影响严重,且有关各向异性地层上下界面不平行的研究未见有相关报道。采用三维有限元素法对各向异性地层进行模拟,研究了界面倾角、地层厚度、围岩电阻率对双侧向测井响应的影响。结果表明,地层倾角对双侧向测井有一定的影响,且倾角越大影响越严重;相同界面倾角对各向同性与各向异性地层中的双侧向响应影响程度也不同。
Dual laterolog is a commonly used logging tool to obtain formation resistivity. In the actual logging environment,because of unconformity,fault and other factors exist,the upper and lower interfaces were not parallel and the response of dual laterololg response in the horizontal wells can not reflect the formation information. The dual laterolog response affected by the formation of anisotropic properties in horizontal well,and research on the unparallel interfaces of anisotropic formation does no relevant reports. This paper applied three-dimensional finite element methods to model anisotropic formation,and study the influence of Interface inclination,formation thickness,and resistivity of surrounding rock on dual laterolog response. Results showed that the dip angle of the formation interfaces has a certain influence on dual laterolog response,and the greater the inclination,the more severe the effect. The influence of the same interface inclination in isotropic and anisotropic formation on the dual laterolog response was also different.
