JIRA has a range of custom field types available, but it's up to the admins how they are used. When you add a custom field, you have to choose a type and a "context" as well as a name. The context determines where the field is available - project/issue-type or globally.
So, the answer to your questions really is
>I wnt to know that Is there any global cutom field present in jira?
Possibly. Depends on what you and your other admins have added
>If it is there how can i access it ?
What do you mean by "access it"? Use it on an issue? Configure it? Use it in a search? etc...
