Record, and the feature of drilling well layering each reflecting surface of analysis difference series of strata is combined, carry out layer calibration；On the basis of layer calibration, according to
Have the characteristics that the principle of similar seismic event according to same bed boundary, on seismic data to strike-slip fault two sides different layers into
Row Fine structural interpretation obtains the equal T of different layers0Information；Based on well logging and drilling well field data, the velocity field in research area is established；It adopts
With Depth (depth/m)=v (m/s) * T0(s)/2 formula seeks the buried depth of each layer, and wherein Depth is buried depth, layer for the purpose of v
Average speed, T0For the two-way travel time of back wave.After seeking buried depth, the buried depth of different layers is worked out.Using H (i)=
The formula of Depth (i+1)-Depth (i) seeks the thickness of i-th layer (i is integer, is counted since shallower new stratum), wherein
The thickness that H (i) is i-th layer, the buried depth that Depth (i) is i-th layer, Depth (i+1) are the buried depth of i+1 layer.After obtaining thickness,
Work out the thickness chart of different layers；By i-th layer of thickness chart of strike-slip fault side along strike-slip fault it is inverse walk sliding direction translation j away from

Sinistral strike slip tomography breaks to Lower Cretaceous Series top surface, corresponds to it and terminates the activity time as Early Creataceous Epoch Mo.Under today state,
Seagap tomography Sinistral strike slip tomography two sides Middle Jurassic series thickness is discontinuous, there is mutation, illustrates that Middle Jurassic series is strike-slip fault
The stratum deposited before movable or when activity.After the Lower Jurassic Series thickness right lateral in tomography east side is translated any distance, equal nothing
Method realization is not mutated by the realization gradual change of Seagap tomography Sinistral strike slip tomography two sides stratum, therefore, it is considered that Middle Jurassic series is
Sedimentary formation when Seagap tomography Sinistral strike slip faulting.
With continued reference to Fig. 4, under today state, Seagap tomography Sinistral strike slip tomography two sides Lower Jurassic Series thickness occurs prominent
Become, discontinuously, illustrates that Lower Jurassic Series are the stratum that deposits before Strike slipping or when activity.On this basis, with continued reference to
Fig. 5 has found Seagap tomography Sinistral strike slip tomography two sides after the Lower Jurassic Series thickness right lateral in tomography east side is translated 24km
On stratum can coincide very well, therefore, it is considered that Lower Jurassic Series are sedimentary formation before Seagap tomography Sinistral strike slip faulting.According to
This, it is believed that the Seagap tomography Sinistral strike slip faulting time is latter stage in initial stage in Middle Jurassic epoch to Early Creataceous Epoch, Sinistral strike slip
Displacement reaches 24km.
