Abstract

An oil drill rod connector is a drill rod connector applied in the operation of oil and natural gas wells, which can realize the wire transmission of electric power and signals as well as power transfer and circulating drilling fluid at the same time. The connector adopts the double-shoulder structure, the outer wall of the front of the body of the male connector and the inner wall of the body of the corresponding female connector are respectively provided with three conductive rings which are respectively connected with three wires in the annular space of an inner barrel and the bodies of the male and the female connectors, the wires are homogeneously distributed along a circle, and the bodies of the male and female connectors and the annular space of the inner barrel are filled and sealed with insulation material. When the male connector and the female connector are rotated together, the three couples of conductive rings are respectively in contact with and matched with one another, thereby the three wires in the male connector and the three wires in the female connector are respectively connected to realize wire transmission of electric power and signals. The utility model satisfies the drilling operation requirements such as transmitting power and drilling fluid and the like, and simultaneously realizes transmission of electric power and signals from the ground to wells by the drilling rod and builds a wire real-time bidirectional closed-loop observation-and-control information channel with the drill rod.

Description

But the joint of petroleum drill rod of a kind of transferring electric power and signal

Technical field

The utility model relates to a kind of tool joint that is used for oil, Natural Gas Drilling Operation, can carry out the wire transmission of electric power and signal in transferring power, circulating fluid.

Background technology

Present oil, the tool joint in the Natural Gas Drilling Operation, transferring power, circulating fluid only, the signal of down-hole mainly transmits by mud-pulse.Continuous development along with rotary steerable drilling technology, geologic steering drilling technology and advanced drilling technologies such as diagnosis of drilling well dynamic parameter down-hole and control technology, requirement can be with the various information of boring collection in real time, transmission, processing, feedback and applied geology and well, so that can in time adjust construction technology to drilling process.At present, mud-pulse is measured as one of industrial standard of measurement while drilling (MWD) and the transmission of well logging during (LWD) tool data, and its desirable transfer rate is 2~5bit/s; Numerous parameters can not be really satisfied with boring the requirement of transmission real-time, the two-way closed-loop information transmission of ground and down-hole can not be carried out.Simultaneously, along with the development of new drilling, new technology, underground survey control instrument and downhole hardware are more and more higher to the demand of electric energy, and battery and down-hole turbine generator far can not meet the demands.So need be a kind of when satisfying normal drillng operation requirement, can set up the wire transmission joint of petroleum drill rod of wired drilling real time bidirectional closed loop measurement and control National Information Infrastructure again by ground to delivered downhole electric energy and signal.

Summary of the invention

For overcome present oil, tool joint in the Natural Gas Drilling Operation can not transmitting electric power, can not carry out the two-way closed-loop information transmission of ground and down-hole.Along with the development of new drilling, new technology, underground survey control instrument and downhole hardware are more and more higher to the demand of electric energy, and battery and down-hole turbine generator far can not satisfy the needs of current drillng operation.But the purpose of this utility model is exactly the joint of petroleum drill rod that a kind of transferring electric power and signal are provided for on-the-spot drilling well.

The design scheme that its technical problem that solves the utility model adopts is: the built-in male joint inner core of male joint body, be furnished with three male joint leads in the annular space between male joint inner core and the male joint body, three male joint conducting rings are arranged on the outer wall of male joint body front end, three male joint conducting rings are connected with three male joint leads of annular space inside respectively, also be furnished with three female joint leads in the annular space between female joint inner core and the female joint body, on the inwall of the corresponding site that the female joint body cooperates with male joint body front end three female joint conducting rings are arranged, three female joint conducting rings are connected with three female joint leads of annular space inside respectively, and three male joint conducting rings linked to each other respectively with three female joint conducting rings when the male joint body was threaded with the female joint body.Male joint body front end lengthening, the lengthening position is drilled with circular hole, the male joint lead passes from the hole with the male joint conducting ring and is connected, and then the male joint conducting ring is locked on the male joint body with insulation materials, and the annular space between male joint inner core and the male joint body is also used filling insulating material; Corresponding site at the female joint body that cooperates with male joint body front end is connected the female joint conducting ring with the female joint lead, be locked in the female joint body with insulation materials then, and the annular space between female joint inner core and the female joint body is also used filling insulating material.All there is screw thread to be connected with the male joint body with the male joint inner core respectively inside and outside the male joint baffle ring; The female joint baffle ring is tapered, is connected with the female joint inner core by inner thread, fixes by insulation materials between female joint baffle ring and the female joint body; The aperture of male joint baffle ring, female joint baffle ring and male joint inner core, female joint inner core internal diameter are identical.

The utility model has the advantages that, when satisfying normal drillng operation requirement such as transferring power, circulating fluid; Can connect realize by ground setting up wired drilling real time bidirectional closed loop measurement and control information channel by drilling rod to delivered downhole electric energy and signal.
