sed does not understand columns, and getting it to do so through a complicated enough regex can be ugly.

awk does understand columns, and can have expressions with more than one regex in them.

Code:
awk -F"|" '($2 ~ /regex1/)||($2 ~ /regex2/) { 
        $2="";
        gsub(/[|][|]/, "|");
}' filename

NAME
replace - a string-replacement utility SYNOPSIS
replace arguments DESCRIPTION
The replace utility program changes strings in place in files or on the standard input. Invoke replace in one of the following ways: shell> replace from to [from to] ... -- file_name [file_name] ... shell> replace from to [from to] ... < file_name from represents a string to look for and to represents its replacement. There can be one or more pairs of strings. Use the -- option to indicate where the string-replacement list ends and the file names begin. In this case, any file named on the command line is modified in place, so you may want to make a copy of the original before converting it. replace prints a message indicating which of the input files it actually modifies. If the -- option is not given, replace reads the standard input and writes to the standard output. replace uses a finite state machine to match longer strings first. It can be used to swap strings. For example, the following command swaps a and b in the given files, file1 and file2: shell> replace a b b a -- file1 file2 ... The replace program is used by msql2mysql. See msql2mysql(1). replace supports the following options. o -?, -I Display a help message and exit. o -#debug_options Enable debugging. o -s Silent mode. Print less information what the program does. o -v Verbose mode. Print more information about what the program does. o -V Display version information and exit. COPYRIGHT
