The Petroleum Resource Estimation Of The Beier Sag In Hailaer Basin

Petroleum resource evaluation is the combination product of petroleum geological, comprehensive geological exploration and development study and systems engineering, is the link and bridge between the exploration and development of oil and gas and decision-making and planning. The purpose of this paper is to obtain the quantitative data of oil and gas resource potential of Beier sag, through the research about evaluation of hydrocarbon resources of Beier sag in Hailar Basin, to provide a scientific basis for a planning of oil and gas exploration and development in this region.In this paper, Bell sag source rocks evaluation method used is a comprehensive Fufen method. Hydrocarbon source rock evaluation results show that the Damoguaihe group source rocks of the Bell sag contribute little to the oil and gas generation. Nantun group source rocks, especially the n1s source rocks is the main source rocks of Beier sag.In the "three history" study, the study of the burial history modeling used BaseMod software, obtained the main deposition period of source rocks of Bell sag was started from fhxhd to the end of Yimin Group. Thermal history of using EASY% Ro method obtained that from Tongbomiao group period to the present, trend of Temperature gradient was increased firstly, then the same and then downward lastly. Hydrocarbon generation history of using chemical kinetic method, derived the time of hydrocarbon source rocks most generation was in concentrate between 130-90 million years, and has the characteristics of rapid, hydrocarbon stop now.This study to calculate the amount of resources as the core. This thesis analyzes and studies the methods of resource estimation, through analyze and study for many of evaluation methods, applicability and accuracy and so on, combination with the actual geology and geochemical features of hydrocarbon source rock of Beier sag in Hailar Basin, I selected chemical kinetics in geochemical methods and elemental method as the calculation of the study area, obtained quantitative data of oil and gas resource potential in this sag. So this paper provided a scientific basis for a planning of oil and gas exploration and development in this region.
