| 摘 要： | 在水平井中，由于重力的影响，往往会导致仪器偏心和泥浆侵入不对称。通过建立上、下各3层介质的水平井模型，采用三维有限元法研究了仪器偏心、泥浆侵入对水平井中双侧向测井响应的影响，并将这些影响因素与直井进行了对比，总结了水平井与直井中仪器偏心、泥浆侵入对双侧向测井影响的异同点。

| Abstract: | Generally because of the influence of gravity,eccentric well logging tools and asymmetric mud invasion were induced in horizontal wells.A model with 3 layers in each of the upper and lower layers was established in horizontal wells,the impacts of eccentric logging tools and asymmetric mud invasion on dual laterolog response in horizontal wells were analyzed by 3D finite element method,which were compared with those in vertical wells.The differences of impacts of eccentric logging tools and mud invasion on dual laterolog response between horizontal wells and vertical wells are summarized based on numerical simulation results. |
