FIELD JOINT FOR A DOWNHOLE TOOL
First Claim
1. A field joint for connecting a first downhole tool module and a second downhole tool module, the first downhole tool module having a first housing and a first electrical line disposed therein, the second downhole tool module having a second housing and a second electrical line disposed therein, the field joint comprising:
- a bulkhead coupled to the first tool module and having a first connection face defining a portion of an exterior of the first tool module, the first connection face including a first conduit aperture, the first conduit aperture being configured for receiving an electrical connector assembly;
a first electrical connector assembly configured to be received at least in part in the first conduit aperture, the first electrical connector assembly being releasably coupled to the exterior portion of the first tool module, the first electrical connector assembly including a first connector having a first end adapted for electrical coupling to the first electrical lines and having a second end;
a connector block coupled to the second tool module and having a second connection face defining a second conduit aperture positioned to substantially face the first conduit aperture when the first and second tool modules are joined; and
a second electrical connector disposed in the second conduit aperture, the second electrical connector being electrically coupled to the second electrical line and configured for establishing an electrical contact with the second end of the first connector when the first and second tool modules are joined.

Abstract
A field joint for connecting a plurality of downhole tool modules is disclosed. The modules include a housing and an electrical line. A bulkhead is coupled to a first module that includes a first conduit aperture for receiving an electrical connector assembly. The first electrical connector assembly is releasably coupled to the exterior portion of the first module and includes a first connector having a first end adapted for electrical coupling to an electrical line. A connector block is coupled to the second module that includes a second conduit aperture positioned to substantially face the first conduit aperture when the first and second modules are joined. A second electrical connector is disposed in the second conduit aperture and is electrically coupled to an electrical line such that an electrical contact is established with a second end of the first connector when the first and second modules are joined.

10. An apparatus, comprising:
-
a first module including at least one inlet for receiving formation fluid from a formation penetrated by a wellbore within which the apparatus is configured to be positioned, the inlet being fluidly coupled to a first auxiliary line, wherein the formation fluid is drawn into the tool by a displacement system operatively coupled to the first auxiliary line; a second module including a hydraulic pump, the pump being fluidly connected the displacement system via at least two hydraulic lines; a third module including an electrical controller communicably coupled to a plurality of electrical lines, the electrical lines being communicably coupled to each of the first and second modules; and a connector disposed between at least two of the modules, wherein the connector includes at least two hydraulic line connections and two auxiliary line connections; wherein the first auxiliary line receives virgin formation fluid and the second auxiliary line receives contaminated formation fluid; and wherein a first of the at least two hydraulic lines provides hydraulic fluid from the second module and a second of the at least two hydraulic lines provides hydraulic fluid to the second module.
