裂陷盆地构造-热演化模拟

平衡剖面正演模拟技术可快速、有效地正们盆地或局部构造的形成过程,合理地挪释盆地演化史和局部构造发展史.裂陷盆地构造沉降数值模拟可以估计上地壳与壳下岩石圈的伸展率及岩浆侵入体积.伸展率可用以计算裂陷盆地的古热流史,为预测烃源岩的演化程度提供依据. 

TECTONIC-THERMAL MODELING OF RIFTING BASIN

Forward modeling of balanced cross section has become a basic technique for hydrocarbon explorationThe technique can check various hypotheses rapidly and give out a reasonable model for interpretation. It can also demonstrate the deformation history dynamically and provide evidence of formation and evolution of hydrocarbon. The subsidence history of rifting basin can be divided into 3 periods, i. e. rifting stage, postrifting stage and inverted stage. The extensional ratio can be used to calculate thermal flow, which can predict the petroleum potential.0 Daqing Research Institute 0f Petroleum Explorati0n Development, Daqing l637120 Zhongyuan Research Institute of Petroleum Fxploration Development, CNPC0 Daqing Research Institute of Petroleum Exploration DeveIopment, Daqing l637l2
