The answer is found in the docstring of the Model.write():
"""
...
This format is a list of triplets executed sequentially, where each
triplet is a command to execute on the set of records. Not all
commands apply in all situations. Possible commands are:
``(0, _, values)``
adds a new record created from the provided ``value`` dict.
``(1, id, values)``
updates an existing record of id ``id`` with the values in
``values``. Can not be used in :meth:`~.create`.
``(2, id, _)``
removes the record of id ``id`` from the set, then deletes it
(from the database). Can not be used in :meth:`~.create`.
``(3, id, _)``
removes the record of id ``id`` from the set, but does not
delete it. Can not be used on
:class:`~odoo.fields.One2many`. Can not be used in
:meth:`~.create`.
``(4, id, _)``
adds an existing record of id ``id`` to the set. Can not be
used on :class:`~odoo.fields.One2many`.
``(5, _, _)``
removes all records from the set, equivalent to using the
command ``3`` on every record explicitly. Can not be used on
:class:`~odoo.fields.One2many`. Can not be used in
:meth:`~.create`.
``(6, _, ids)``
replaces all existing records in the set by the ``ids`` list,
equivalent to using the command ``5`` followed by a command
``4`` for each ``id`` in ``ids``.
.. note:: Values marked as ``_`` in the list above are ignored and
can be anything, generally ``0`` or ``False``.
"""
It's (1, id, {'field_1': value_1,'field_2': value_2,}). But you should use write instead of create because in create it doesn't make any sense to change non-existing records of a x2many field.
