The traditional TTI-R-o method uses virtinite reflectance as the indicator of the organic matter maturity, and then makes it a dominant parameter during the simulation of organic matter hydrocarbon generation history. However, this method only takes virtinite reflectance as a function of time and temperature, but ignores not only the influence of pressure and catalyst, but also the follow-up generation contradiction. Actually, this method is difficult to correctly describe the organic matter hydrocarbon generation history. By a variety of analysis and comparison, hydrogen index (I-H) is found to be the parameter with the above characteristics. I-H is also the synthetical effect result of time, temperature, pressure and catalyst and their dynamic change. So it is appropriate to use I-H, instead of R-o, as the dominant parameter during the hydrocarbon generation history of organic matter. Then it is possible to establish a method on the basis of the hydrogen index to calculate the hydrocarbon generation history the comprehensive simulation method of time, temperature, pressure, catalyst and index, called TTPCI-I-H method. And it is successfully applied in hydrocarbon generation history simulation. The actual simulation results in Shengli oilfield show that TTPCI-I-H method is obviously better than TTI-R-o method.
