| Geometric Characteristics of the He-125 Fault and Its Control over Sediment and Reservoir Distribution, Dongying |
| Based on researches on characteristics of the He125 fault,the authors have found that the arcuate fault is parallel to the fault strike and is the combination of fault-trough and fault-ridge,as evidenced from the profile.In the cross section,the fault can be divided into three parts,namely,vertical-slip part,dip-slip part and horizontal-slip part.A comparison of their growth indices shows that the arc center is greater than the arc flank,but things are just the opposite for their fault dip.There exists some relationship between the geometric features of the fault and its kinematic characteristics.Different geometric characteristics of different localities show the difference of their kinematic characteristics.Geometric features of the fault system control the distribution of sediments.Viewed from the surface,the arc center is the counterpart of the turbidite fan,the arc flank is the boundary of the turbidite fans,the fault trough is the recharge path of the turbidite fan,and the fault ridge is the watershed line of different recharge areas.Viewed from the cross section,the lower dip-slip part corresponds to far-bank turbidite,and its middle and upper part corresponds to the slump turbidite fan,thus forming a typical corresponding phenomenon for the arc and fan.The fault characteristics also play an important role in migration pathway and hydrocarbon accumulation. |
