针对双感应测井受到泥浆侵入和围岩等因素影响，采用小生境技术的改进遗传算法对双感应测井进行原状地层电阻率和侵入半径等参数反演。利用多层层状地层模型对算法进行验证，反演结果能较好地反映地层模型参数。实例资料的应用结果表明，改进遗传算法反演出的地层电阻率使测井解释结论更加接近试油结论。

For the reason that dual induction logging method will be affected by such factors as mud invasion and wall rocks, an im?proved genetic algorithm based on niche technology is proposed to perform inversion of virgin formation resistivity, invasion radius and other formation parameters. The multiple layered medium is set as model to conduct algorithm verification, The results can well reflect the formation parameters. With the actual dual induction logging data, the new interpretation drawn by the inversion of virgin formation resistivity is more close to the test data.
