Definitions
- the present invention relates to an assembly for producing a threaded joint used for drilling and operating hydrocarbon wells, the assembly comprising a first and a second tubular components, provided for one one threaded end of the male type and the other of a threaded end of the female type, the two ends being able to cooperate by self-locking screwing.
- the invention also relates to a threaded joint, also called connection, resulting from the screw connection of the two tubular components.
- any element of substantially tubular shape intended to be assembled with another element of the same type or not to constitute in fine is a fitting fit drilling a hydrocarbon well, either an underwater riser for maintenance such as “work over riser” or a column casing or production of large thickness involved in the operation of the well.
- the invention applies in particular to the components used in a drill string, such as, for example, “Drill Pipes”, “Heavy Weight Drill Pipes” heavy rods, “Drill Collars” drill collars and parts thereof. connection of heavy rods and rods called “tool joint”.
- each component used in a drill string generally comprises an end provided with a male threaded zone and an end provided with a female threaded zone each intended to be assembled by screwing with the corresponding end of the thread.
- another component the assembly defining a connection.
- the lining thus formed is rotated during drilling at the surface of the well; therefore, the components must be screwed together with a large torque to be able to transmit a sufficient torque to drill in the well without unscrewing or surviving.
- the tightening torque is generally achieved through the cooperation in clamping abutment surfaces provided on each of components to be screwed.
- the widths of the thread peaks (or teeth) are gradually increasing for the threads of the male end, respectively female, when moving away from the male end, respectively female.
- the male and female threads (or teeth) end up locking one in the other in a position corresponding to the locking point. More specifically, the locking occurs for self-locking threads when the flanks of the male threads (or teeth) are locked against the flanks of the corresponding female threads (or teeth).
- the male and female threaded zones screwed into each other admit a plane of symmetry according to which the width in the middle of the common height of the male and female teeth located at the end of the zone Threaded male is the width in the middle of the common height of the male and female teeth at the end of the female threaded area.
- the screwing torque is collected by substantially all the contact surfaces between the sidewalls, a total area very much greater than that formed by the abutment surfaces of the prior art.
- the lubricant remains trapped in the thread and generates a counter pressure that tends to separate the nested nets into each other.
- the lubricant can be trapped under pressure if the radial or axial clearance is sufficiently low, that is to say if it is less than the thickness of the lubricant applied to the threaded zones. This happens more particularly in the case where the nets are in tight contact, for example at the level of the vertices and funds fillet and at the flanks. As a result, a false reading of the tightening torque is obtained. Then, when put into service under an insufficient tightening torque, the seal may no longer be sealed and excess lubricant under pressure may leak.
- the invention aims to facilitate the circulation of lubricant during the make-up without compromising the seal seal or fatigue resistance.
- the invention relates to an assembly for producing a threaded joint, comprising a first and a second tubular components of axis of revolution and each having at one of their ends at least a first threaded zone formed on the outer or inner peripheral surface of the component according to whether the threaded end is of the male or female type and adapted to cooperate with each other in screwing, said ends ending in an end surface, characterized in that at least one of the threaded zones has, in a longitudinal section passing through the axis, a profile corresponding to a continuous and concave curve portion over at least 10% of the length of the engaged threads of said threaded zone.

- the second threaded zone may be disposed in the extension of the first threaded zone.
- the first and second tubular components may each comprise a metal / metal sealing surface disposed between the first and second threaded zone, the metal / metal sealing surfaces being able to cooperate in tight tightness when the first and second second tubular components are screwed together.
- One of the metal / metal sealing surfaces may be conical, the other sealing surface being then toric.
- the toric surface may be disposed on the male-type end tubular component, the radius of the torus being between 40 and 80 mm, while the conical surface is disposed on the following female-type tubular end component. a taper between 1 and 6 degrees.
- the threaded zone (s) may (may) admit (each) a taper generatrix forming an angle with the axis of revolution of the tubular components, greater than 0.5 degrees and preferably equal to 5 degrees.
- the threaded zone (s) may be self-locking, the threads comprising, viewed along a longitudinal section passing through the axis of revolution of the first and second tubular components, a vertex of net, a net bottom, a carrier flank, an engagement flank, and the width of the thread peaks of each tubular component decreasing towards the tubular component end surface considered, while the width of the net funds increases.
- the threads of the male and female tubular components may admit a dovetail profile.
- the profile corresponding to a concave curve portion may be applied to the farthest threaded zone of the end surface of the male-type end tubular component.
- the least one of the threaded zones admits, in a longitudinal section through the axis, a profile backed by at least two portions of continuous and concave curves.
- the first and last threads threaded areas may be imperfect, so as to provide a game between the tops and nets funds.
- the clearance between the peaks and the bottom of imperfect nets may be between 0.1 mm and 1.5 mm.

- FIG. 1 shows a first embodiment of the invention with a threaded joint in the screwed state of axis of revolution 10, comprising a first tubular component of the same axis of revolution 10 and provided with a male end 1 and a second tubular component of the same axis of revolution 10 and having a female end 2, the male end and the female end being screwed together.
- Both ends 1 and 2 are each terminated by an end surface 7, 8 oriented radially relative to the axis 10 of the threaded joint and are respectively provided with threaded zones 3 and 4 which cooperate with each other for the mutual assembly by screwing two components.
- threaded zones are meant the portions of the circumferential surface of a tubular component having a continuous thread, that is to say without interruption of the threading helix.
- the threaded zones 3 and 4 are of the known type called "self-locking" (also called progressive variation of the axial width of the threads and / or intervals between threads), so that a progressive axial clamping takes place during screwing, to a final locking position.
- self-locking also called progressive variation of the axial width of the threads and / or intervals between threads
- FIG. 2 shows the seal of Figure 1, with the difference that the seal is being screwed.
- Self-locking threaded zones are defined as zones threaded threads having the features detailed below.
- Male threads (or teeth) 32 like female threads (or teeth) 42, admit a constant pitch while their width decreases in the direction of their respective end surface 7, 8, so that during screwing Threads (or teeth) 32 and female 42 end up blocking into each other in a specific position.
- the pitch LFPb between the bearing flanks 40 of the female threaded zone 4 is constant as is the pitch SFPb between the engagement flanks 41 of the female threaded zone, with the particularity that the pitch between the load-bearing flanks 40 is greater than the pitch between the engagement flanks 41.
- the pitch SFPp between the male engagement flanks 31 is constant, as is the pitch LFPp between the male bearing flanks 30.
- the respective pitches SFPp and SFPb between the male and female engagement flanks 41 are equal. between them and below the respective pitches LFPp and LFPb between the male and female bearing flanks 40, themselves also equal to each other.
- FIG. 2 also shows the thickness of the male end 1, ep, also called the critical section of the male end 1, defined not by the difference between the ODp outer diameter and the diameter. internal IDp of said end, but at the base of the threaded zone 3, that is to say at the last thread.
- the thickness of the female end 2, eb, also called the critical section of the female end 2 is defined not by the difference between the outside diameter ODb and the inside diameter IDb, but at the base of the threaded zone 4, that is to say at the level of the last thread.
- the efficiency of the seal is equal to the ratio between the minimum value between the critical section of the male end and the critical section of the female end, and the current section of the tube.
- the current section of the tube is to be connected to the thickness of the threaded components measured away from the threaded areas. This thickness is then constant for the male component and for the female component. The thickness is calculated both from the difference between ODb and IDb, only from the difference between ODp and IDp.
- the notion of joint efficiency is to be related to the fatigue strength of the joint.
- Figure 3 shows a second embodiment of the invention with a threaded joint in the screwed state.
- the joint comprises an axis of revolution 10, comprising a first tubular component of the same axis of revolution 10 and having a male end 1 and a second tubular component of the same axis of revolution 10 and having a female end 2, the male end and the female end being screwed together. Both ends 1 and 2 are each terminated by an end surface 7, 8 oriented radially relative to the axis 10 of the threaded joint.
- the first and second tubular components are respectively provided with a first and a second threaded zones 3a, 3b and 4a, 4b which cooperate with each other for the mutual assembly by screwing of the two components.
- the threaded zones are also of the known type called "self-locking".
- the threaded zones 3a and 3b of the male end are aligned in the same direction 20.
- the second threaded zone 3b is arranged in the extension of the first threaded zone 3a.
- the threaded zones 4a and 4b of the female end are aligned in the same direction 20.
- the first 3b and the second 3a threaded zones of the male end are respectively surrounded by a first 38b, 38a net and a last 39b, 39a net.
- the first 4a and the second 4b threaded zones of the female end are respectively framed by a first 49a, 49b net and a last 48a, 48b net.
- a stepped joint comprising, for each male or female component, two threaded zones that are no longer aligned but arranged in parallel directions.
- FIG. 4 is a detailed view of the male component of FIGS. 1 and 2.
- at least one of the threaded zones admits, in a longitudinal section passing through the axis 10, a profile backed by a portion of continuous and concave curve C over most of the threads engaged of said threaded zone.
- profile backed by a portion of curve the fact that, when making a longitudinal section through the axis 10, the vertices of the nets each inscribe on a single curve flat to the cutting plane.
- it is the threaded zone 3 of the male end which admits the profile along the curve C.
- continuous curve is meant that the curve does not admit a point of inflection.
- concave curve means that it is oriented to widen the profile of the threaded zone. This profile also applies to at least 10% of the length of the nets engaged.
- Engaged nets are understood to mean the nets which come into contact with the threads of the conjugate part, as opposed to the so-called "imperfect" threads, which are located at the ends of the threads and which hardly incur any screwing forces in the threads. the extent that they do not come into contact with the nets of the conjugate part.
- the vertices 35a of the threads of the male threaded zone are backed by the curve portion C.
- FIG. 4 also shows a profile SP of nets known from the prior art which clearly differs from the blunt profile of the nets backed by the curve C according to the invention. It can thus be seen that the digging carried out in the threading by the curve C ensures the circulation of the lubricant. It is also seen that the hollow profile of the thread does not affect the critical section of the threaded element on which said profile is made. As a result, the effectiveness of the seal is preserved.
- the invention could be applied not to the male threaded zone, but rather to the female threaded zone.
- FIG. 5 is a detailed view of the male component of FIG. 3.
- at least one of the threaded zones admits, in a longitudinal section passing through the axis 10, a profile corresponding to a portion of a continuous and concave curve C over the majority of the engaged threads of said threaded zone.
- it is the threaded zone 3 a of the male end which admits the profile along the curve C.
- the fact that the concave curve profile is applied to the second threaded zone 3 a of the male component, that is, that is the farthest from the end surface 7 of the male-type tubular end component 1 is advantageous. Indeed, in this way, the grease pressure is reduced where the thickness of the male component is the lowest.
- the portion of the curve may be, by way of nonlimiting example, a portion of a polynomial curve, an ellipse or even a circle.
- the threaded zone is hollowed out over a portion so that the height of the threads is reduced at most by a value between 10 and 90% of the initial height of the threads.
- the threads (or teeth) male and female admit a profile, seen in a longitudinal section through the axis of the threaded joint 10, overall appearance in dovetail so that they are firmly interlocked into one another after screwing. This additional guarantee eliminates the risk of so-called "jump out", which correspond to a separation of the male and female threads when the connection is subjected to significant bending or pulling forces.
- the geometry of the dovetail threads increases the radial rigidity of their assembly with respect to nets commonly called “trapezoidal", the axial width of which decreases from the base to the top of the threads.
- the threads 3 and 4 of the tubular components are oriented along a taper generator 20 so as to facilitate the progression of the screwing.
- this taper generator forms an angle with the axis 10 in a range of 1 degree to 6 degrees.
- the conicity generator is in this case defined as passing through the middle of the carrier flanks.
- the tops of the teeth and the bottom of the hollow male and female threaded areas are parallel to the axis 10 of the threaded joint.
- the first and the second tubular components each comprise a metal / metal sealing surface 37, 47 disposed between their first and second threaded zones, the metal / metal sealing surfaces 37 and 47 being able to cooperate with each other. sealing tight when the first and second tubular components are screwed together.
- one of the metal / metal sealing surfaces 37, 47 is conical, while the other is toric.
- the radius of the torus, disposed on the male-type end tubular component may be between 40 and 80 mm, while the conical surface is disposed on the female-type end tubular component with a taper of between 5 and 20 mm. 15%.
- the vertices of the threads of the female-type threaded end are interfering with the troughs of the male threaded end threads, in the case where part of the profile of the male threaded zone, seen in a sectional view. longitudinal passing through the axis 10 of the connection, is backed by a portion of concave curve. As a result, close contact is maintained between the female thread peaks and the male thread cavities, while a variable clearance is provided between the male peaks and the female thread cavities.
- the first and last threads of the threaded zones are imperfect.
- Imperfect threads are defined as threads 38, 39 and 48, 49 located at the ends of threads 3 and 4 (in FIG. 2), the height of which has been leveled so that a clearance is formed between the tops and the ends. of fillets.
- the invention also encompasses the embodiments which consists in producing on the same thread two or more portions of concave curves. This makes it possible to limit the decrease in the height of the net and thus to maintain the catch between the nets. In other words, the circulation of the grease is provided throughout the threading with a succession of delays, while protecting the connection risks of separation of the nets ("jump out").
- Figure 8 An example is given with Figure 8 on which there is shown an embodiment corresponding to two delays. In this case, one of the threaded elements has a thread with a thread profile backed by two concave curves.
- the invention also encompasses various embodiments relating to the positioning of the concave curve on the thread profile.
- the curve can be centered on the middle of the thread, just as it can be shifted towards one of the ends of the thread.
- Figure 7 is an exemplary embodiment in which the curve is offset and not centered.
- the threaded joint resulting from the assembly of the tubular components according to the invention is obtained with a tightening torque in accordance with the standards imposed.
- This type of seal is particularly used in drilling applications.
- the vertices of the male and / or female threads may be interfering with the depressions of the female and / or male threads. This avoids trapping lubricant, the latter being driven during screwing to the flanks of the nets.
- the invention can be applied to connections having two or more consecutive threaded zones and staggered, that is to say whose tapered axes of the threaded areas are non-concurrent parallel.
- the invention can also be applied to connections comprising a plurality of threading propellers, these connections then comprise so-called multi-start threads. In this case, the helix of the second threaded zone is shifted relative to the helix of the first threaded zone at an angle alpha.
- the invention provides a method of manufacturing a tubular component applicable to both a male end component and a female end component.
- This method is characterized by the fact that one of the ends of the tubular component is first machined so as to obtain a profile, in a longitudinal section passing through the axis, corresponding to a portion of the curve. continuous and concave, and after that one proceeds to the machining of the threaded zone.
- This method has the advantage of being simple in that the first step is to perform a delignage of the component end quite controllable according to a turning operation.
- the second machining step which occurs later in the slicing stage, is a conventional step of machining the threaded zone.
