地震井间曲射线反射加透射层析（CCRTT）

Seismic Crosshole Curved Ray Reflection &Transmission Tomography(CCRTT)

本文提出了一种新的地震井间层析方法，即曲射线反射＋透射（ＣＣＲＴＴ）层析方法。该方法可以提高对油气储层层析成像的分辨率。适合用于储油层薄且与周围地层速度对比差大的油区。文中还从理论上ＣＣＲＴＴ可以提高分辨，使成像射线分布均匀，改善图像重建质量，对油田资料用ＣＣＲＴＴ图象重建的结果可以分辨１ｍ厚的油层。

This peper provides a new seismic crosshole tomography method-Curved Ray Reflection & Transmission Tomography(CCRTT). The technology conld enhance the resolution of oil and gas reservoir beds tomography image, and it is suitable for such condition as thin reservoir beds and with its high velocity contrast between the surrounding beds in the oil filed.The peper also proves theoretically that CCRTT may increase the resolution, yield uniform distribution of image ray and improve the quality of image reconstruction. The result of image reconstruction of SL Oil Filed could resolve the oil reservoir beds with one meter of thickness in the field.
