Abstract：The magnetic data surveyed in S103 well zone are upward continued to certain height and vertical second derivative to the data is carried out,which results in magnetic anomaly trap reflecting Fangshenpao Formation basalt with middle depth. The boundary between high (positive) magnetic and low (negative) magnetic anomaly is divided according to distribution of residual magnetic anomaly and zeroline of magnetic anomaly,the high magnetic anomaly zone in the areas can be viewed as general distribution range of magnetic basalt bodies and basaltabsent zones are ranges of negative magnetic anomaly,based on which the two basaltabsent zones are drawn. The 2.5D mancomputer interaction approach is used to computer magnetic anomaly section and apparent isopach map is drown. The exploration practice showed that the distribution and thickness of Fangshenpao Formation basalt directly affect the reservoir of low buriedhill,and the authors discussed the relationship between the distribution of basalt and low buriedhill reservoir.
