摘要
Based on relationship between TOC and hydrogen index IH, the lacustrine source rock in the Jizhong Depression can be divided into three class as follows: high quality source rock with TOC>2%, good source rock with TOC=1%~2%, and poor source rock with TOC=0.5%~1%, respectively. According to evaluation of logging data, distribution and prospect of potential resource, the future favorable exploration area should focus on the buried hill, Paleocene deep lithological layer, and shallow and middle complex fault-block structure in the Raoyang sag.
