A concentric wet connector system useful for connecting, disconnecting and reconnecting small diameter fluid lines (40, 42, 44) and electrical lines (46) downhole in oil and gas wells, the system comprising first and second slidably engageable well tubulars (32, 38) coaxially disposed around a longitudinal bore, each well tubular having a circumferentially extending wall section containing at least one auxiliary conduit leading to a connector port 64 paired and communicating with a connector port 66 of the other tubular. The connector ports in each well tubular are preferably spaced apart both circumferentially and longitudinally. The connector ports of each respective pair are preferably disposed at substantially the same well depth whenever the two well tubulars are fully engaged, and communication between the connector ports of each pair is preferably established by means of an annular flow channel 74 (for fluid lines) or an annular recess with an electrically conductive band 104 (for electrical control wires) to avoid the need for specific rotational alignment between the well tubulars. Use of the system for connecting fluid lines and/or electrical control wires to well tools and monitoring equipment suspended below a production packer and annular safety valve in a well bore is also disclosed. The tubulars are also locatable by shear collar (150) in a position short of full engagement (FIG. 8) in which ports (64, 140) on the inner tubular (32) are both open to annular channel (74) to permit flushing of these ports.
