A resistance wire is wound at the periphery of the nonmetallic liner, heat insulation material is wrapped at the periphery of the resistance wire, and outer packing cloth is wrapped outside the heat insulation material. A baffle which is made of the nonmetallic material is arranged on the two ends of the heating device. A temperature inducting device passes through the nonmetallic liner and has a lead connected with an automatic temperature controller, and the temperature controller is provided with a lead connected with the two ends of the resistance wire. The utility model has the effects that glass steel of nonmetallic material is used as an inner liner, the resistance wire is laid at the periphery, thereby not only meeting the temperature which is needed in an apparatus heating experiment, but also meeting the requirement of non-electromagnetic interference. Through a temperature control system, constant temperature can be kept at different temperature points according to requirements. The utility model has the advantages of simple structure, light weight, convenient removing, etc.
Description
Technical field
The utility model relates to petroleum industry exploration and development logger and makes the field.Being particularly related to a kind of heating apparatus of induction instrument aratus, is a kind ofly under no magnetic stripe spare induction logging instrument to be heated, and can keep the heating apparatus of steady temperature as required at different temperature spots.
Background technology
Induction instrument aratus is the common equipment of present oil exploration well logging.Wherein the probe segment of induction instrument aratus has special requirement.Such as, when instrument is heated experiment, be no magnetic environment around requiring.At present, the common practice of domestic and foreign current is to set up fixing pot arch in the barrack of full wooden structures, and pot arch is a bulky permanent construction, and agent structure must adopt special-purpose material, not only costs an arm and a leg, and can not move.
Summary of the invention
The purpose of this utility model provides a kind of heating apparatus that is used for induction instrument aratus, can satisfy oil exploration logging equipment induction instrument aratus heat the experiment no magnetic specific (special) requirements.And has advantage simple to operate, that cost is lower, in light weight, easy heating apparatus is settled in carrying.
The technical solution adopted in the utility model is: the heating apparatus that is used for induction instrument aratus comprises nonmetal inner bag, resistance wire, heat-barrier material, external packing cloth, temperature sensing device and Automatic Temperature Control, it is characterized in that: nonmetal inner bag is cylindric, internal diameter is between the 95-120 millimeter, thickness is between the 5-10 millimeter, and length is between the 4000-5000 millimeter.Periphery at nonmetal inner bag is wound with resistance wire, and the periphery of resistance wire is enclosed with heat-barrier material, and heat-barrier material is wrapped with external packing cloth.Be fixed with the baffle plate that nonmetallic materials are made at the two ends of this heating apparatus.There is temperature sensing device to pass nonmetal inner bag, the nonmetal inner bag temperature inside of energy measurement.There is lead to connect Automatic Temperature Control on the temperature sensing device.There is lead to connect the two ends of resistance wire on the attemperating unit.Automatic Temperature Control makes this device keep steady temperature at different temperature spots as required as the core of control and sampling.
The material of described nonmetal inner bag and baffle plate can be pottery, fiberglass or high temperature resistant polytetrafluoroethylene.
