摘要
苏堤地区位于西湖凹陷浙东中央背斜带的南部，现有钻井天外天一井揭露平湖组1549．5米。该井平湖组沉积相历来有多种看法，本文比较了前人工作成果，提出新的认识。根据过渡相盆地沉积机制，运用旋回地层学重新分析了地层特征，对该地区沉积环境演化提出新的见解。
Sudi Division is located at the south part of center anticlinal zone. Pinghu Fm. of TWT Well 1 (1549.5m in thickness) have been interpreted by various views. This paper puts forward new points about depositional evolution based on depositional mechanism of transitional basin and stratum characteristics described by cyclostratigraphy.
