Based on the date of outcrop, log and lithology, sequence stratigraphic division and correlation were made on Neopaleozoic in south of North China Basin, and high-precision geologic correlation framework was built up in the basin.2. In the term of sedimentary features of Neopaleozoic in south of North China Basin, lateral variation of sedimentary facies was studied selectively in Benxi-Taiyuan Formation, Shanxi Formation, Lower Shihezi Formation, Upper Shihezi Formation and Shiqianfeng Formation. Lithofacies paleographic features and the sedimentary evolutionary process of Late Paleozoic in south of North China Basin were worked also.3. On the basis of sand-bodies Isopach figure drawing, the distribution of major reservoir sand-bodies of Neopaleozoic in south of North China Basin was studied. Basing on the distribution of sand-bodies in sequence stratigraphic framework, combining the development and distribution features of barrier and underwater distributary channel, there is a disquisition on the distribution regularity of pay reservoir sand-bodies of Neopaleozoic in this area.

以殷鸿福等（1998）归纳总结的非威尔逊旋回理论为指导，从理论上阐述了非史密斯地层形成过程：造山带区古大洋相当复杂，尤其是中国古特提斯域古大洋，多为多岛洋，多岛洋是一个宽阔的但不干净的洋，它在其各个演化阶段，始终充满着由裂解地块、裂谷、海道、微板块与次级小洋盆、火山岛弧、海山与边缘海等不同裂离与聚合程度的、海陆相间的多岛洋盆；多岛洋盆在其整个洋陆转化进程中，往往所经历的是多期开合与多期次软碰撞，故由非威尔逊旋回转化而来的造山带混杂岩带地层一般都经历过多期强烈的构造混杂，使造山带演化不同期次、同期次不同阶段、不同大地构造相、不同沉积古地理单元、不同构造层次地层体在极短程内相互拼贴、无序叠置。
