Chang 7 source rocks of Triassic Yanchang Formation in Ordos Basin are the main resources for oil and gas of Mesozoic in Ordos Basin, so it is very important to study their organic matter abundance for the evaluation of the source rocks. By using ΔLogR technique, one TOC computational model can be obtained by using multi-linear regression analysis of the acoustic time logging curves, resistivity logging curves, density well logging curves and TOC of the source rocks from the experimental analysis. The result shows that the model can reflect the change trend of TOC of Chang 7 source rocks precisely. And the calculation is simple and convenient, so this model can be widely used in the recovery of TOC of Chang 7 source rocks in Huachi-Qingyang area.
