The correct syntax would be:

class BaseModelExtend(models.AbstractModel):
        _name = 'basemodel.extend'
        @api.model_cr
        def _register_hook(self):
                origin_create = models.AbstractModel.create
                @api.model
                @api.returns('self', lambda value: value.id)
                def create(self, vals):
                        res = origin_create(self, vals) 
                       _logger.info("THIS IS OK")
                       return res
                models.AbstractModel.create = create
                return super(BaseModelExtend, self)._register_hook()

we have already changed base method name_get, see this it may help.

from openerp.models import BaseModel
from openerp import api

@api.multi
    def name_get(self):
        result = []
        cr, uid, context = self.env.args
        if uid in context.keys():
            user = self.env['res.users'].browse(context.get('uid'))
            if user:
               for record in self:
                    result.append(record.name)
               return result
BaseModel.name_get = name_get
