Colpitts oscillator : having trouble while respecting Barkhausen criterion, is this criterion insufficient there?
First, your filter is loaded by both R3, which you appear to have taken into account, and by R1, which you appear to have neglected.  

R1 matters because the inverting node of the op-amp should be around 0V, at least if you're running at 10kHz or less for the 741.  This means that R1 appears to the filter as if it were grounded.

Second, you want to design your oscillator with an excess of gain in the amplifying circuit, and design it so that as the amplitude of oscillation increases, the amplifier gain goes down.  This can be as simple as a clipping circuit, and gets more elaborate from there.

Third, the LM741 probably cannot drive a 220\$\Omega\$ resistor on its output -- 2200\$\Omega\$ is probably better.  Yes, a transistorized Collpitts may work with impedance levels of 220\$\Omega\$, but you'd need a beefier op-amp to do that.
