I think that you should use code like this below:

        $query = $this->oQuery
            ->table('table ')
            ->select('field')
            ->where(function ($q) {
                $q->Where('x', '=', 1);
                $q->OrWhere('y', '=', 1);
            })
            ->where(function ($q) {
                $q->Where('z', '>', 1);
                $q->Where('z', '<>', 1);
            });

        $queryObj = $query->getQuery();
        //$check = $query->get();
        echo $queryObj->getRawSql();

And response:
SELECTfieldFROMtable WHERE (x= 1 ORy= 1) AND (z> 1 ANDz<> 1)
