Truth condition is closer, and user is facilitated to carry out the work of horizontal wells.Further, can save time and depth transfer in this way needs
The time wanted improves the target spot depth and Trajectory Design efficiency of the adjustment of subsequent well track and offset well (non-drilling well), reduces and bore
Well stops the equal times, and then lowers drilling cost, improves work efficiency.Seismic profile correction in the prior art needs to receive first
The characteristic point for collecting drilling well, is corrected velocity field, is then carried out to time-domain seismic data using the velocity field after correction
Turn deep, this method is to carry out the correction of service speed field in time-domain data and turn to need to take a long time deeply, to water
The target spot depth and Trajectory Design of horizontal well cannot play good directive function.In contrast, side provided by the embodiments of the present application
Method can quickly provide depth data by being corrected to Depth Domain, with may further be to the target spot depth of horizontal well
And Trajectory Design plays good directive function.
It is real after method in the present embodiment is corrected existing seismic profile using the tectonic model that virtual hierarchy is established
It bores wellbore trace and seismic profile error is smaller, degree of agreement is high, and is to correct immediately, and speed is fast, can be subsequent well
Track adjusts and the target spot depth and Trajectory Design of offset well (non-drilling well) provide accurate depth and Trajectory Design scheme, can improve
Horizontal well drilling efficiency saves drilling time, further decreases production cost.
