You can try using the saveClockBuffers or the displayClockMesh command. You can specify the clock domain for which you need the buffers.

Something along these lines (with the db commands):

dbget [dbQuery -area {27.436 111.547 51.035 125.870 }].cell.name

Replace the coordinates with yours (lower x,y upper x,y). This will return cell names with all the buffers. You will have to postprocess this list to filter out the clock buffers in the selected region. Or check the dbget command. Use the following to check for dbget options:

dbget [dbQuery -area {27.436 111.547 51.035 125.870 }].??
