东营凹陷Es4-Ek油气资源评价

设计开放和封闭两种模拟实验体系进行东营凹陷有机质初次裂解生烃(成油、成气)和原油二次裂解成气的模拟实验.根据模拟实验结果建立并标定相应的化学动力学模型,进而结合该凹陷地史、热史资料进行地质应用得出生烃剖面.利用生烃剖面对研究区的有机质丰度和生烃潜力进行恢复.最终结合烃源岩发育和残留烃情况对研究区进行了生、排烃量的计算,...

Oil and gas resource evaluation of Es4 member and Ek formation, Dongying Depression

Designing open and closed systems to simulate the primary cracking of organic matter from Dongying Depression into hydrocarbon (oil, gas) and the secondary cracking of crude oil into gas. Based on the simulation results, the corresponding chemical kinetic model was established and calibrated. Then we applied the model in geology and got hydrocarbon generation profiles by combining with geological history and thermal history data. After these, the organic matter abundance and hydrocarbon generation potential of the study area were recovered by using hydrocarbon profiles. At last, we combined with the situation of the development of source rocks and hydrocarbon residues to calculate the quantity of hydrocarbon generation and expulsion, and at the same time, determined the migration and accumulation coefficient for oil and gas resource evaluation based on comprehensive geological conditions of the study area. The results demonstrate that the oil and gas resource was 29.65 ?108t and 4.89 ?1011m3 in Es4-Ek of Dongying Depression.
