Abstract：After deposited in reduction environment,organic substance got higher and higher maturity with the increase of depth and time,which is not reversible process. The maturity of organic substance can be expressed by the time-temperature index(TTI value)and vitrinite reflectance(RQ).Having known TTI(or Ro)value and bury history of a formation,we can recover the original formation thickness.I detail principle of recovering the original formation thickness by TTI method and have recovered the original thickness of Triassic system in east Linqing depression by using this method. The accuracy depends on formation temperature,Ro value,geological age and so on.
