Definitions
- Downhole operations often include a downhole string that extends from an uphole system into a formation.
- the uphole system may include a platform, pumps, and other systems that support resource exploration, development, and extraction.
- fluids may be passed from the uphole system into the formation through the downhole string.
- fluid may pass from the formation through the downhole string to the uphole system.
- the downhole string may include various sensors that detect downhole parameters including formation parameters and parameters associated with the downhole string.
- Communication may take place through wired, optical, or acoustical systems.
- Acoustical systems rely upon passage of pressure pulses generated downhole to an uphole receiver.
- the pressure pulses are created by a mud pulser by moving a piston into a choke valve in order to create an additional temporary pressure increase at the pump system on the surface.
- the generated pressure pulse travels with sound speed to the surface.
- the uphole receiver converts the pressure pulses to data indicative of sensed parameters.
- the pressure pulses provide useful information to uphole operators. Therefore, advances in downhole communication systems would be well received by resource exploration and recovery companies.
- a typical mud pulser substantially continuously generates pressure pulses over long time periods, often several days.
- a number of wellbores are currently drilled in formations having temperatures that are above 300 °F (149 °C).
- a majority of currently utilized mud pulsers include oil fillings, elastomers and/or electrical high pressure connectors, all of which tend to deteriorate over time and thus are not suitable for use in high temperature environments.
- the disclosure herein provides pulsers that are suitable for high temperature environments while also being made without oil fillings, elastomers or electrical high pressure connectors.
- a control valve assembly for a downhole wellbore including a body having a first fluid passage defining a fluid inlet and a second fluid passage defining a fluid outlet.

- a solenoid is mounted at the body about at least a part of the magnetic material in at least one of the body and the plunger.
- the solenoid is selectively activated to create a magnetic field across the gap in the magnetic circuit.
- the magnetic field causes the plunger to move thereby narrowing the gap to produce a pressure pulse in the wellbore.
- a resource exploration system including an uphole system and a downhole system including a downhole tool in a wellbore operatively connected to the uphole system.
- the downhole tool includes a pulser having a control valve assembly including a body having a first fluid passage defining a fluid inlet and a second fluid passage defining a fluid outlet. The body is formed partially from a magnetic material.

- a solenoid is mounted at the body about at least a part of the magnetic material in at least one of the body and the plunger. The solenoid is selectively activated to create a magnetic field across the gap in the magnetic circuit. The magnetic field causes the plunger to move thereby narrowing the gap to produce a pressure pulse in the wellbore.

- alternator assembly 46 provides signals to CVA 48 that allow drilling mud to flow through MVA 50 and creates pressure pulses in the mud flow according to the signals.
- CVA 48 creates pressure pulses in the mud flow that provide downhole data from sensors (not shown) operatively coupled to alternator assembly 46 to uphole operators.
- CVA 48 includes a body 60 having a first body portion 62 and a second body portion 64 joined by a sleeve member 66.
- Second body portion 64 may be formed from a corrosion resistant magnetic material such as a soft magnetic material e.g., Vacoflux® 9CR from Vacuumschmelze GmbH and Co. Magnetic and soft-magnetic materials are defined as having a magnetic permeability ⁇ greater than about 1.26 ⁇ 10 -4 N/A 2 (ferromagnetic or ferrimagnetic material).

- Housing 128 may be made from a magnetic material that is also corrosion resistant.
- the solenoid 120 may be placed in a sealed and clean 1-bar environment.
- plunger assembly 160 moves when the solenoid in the control valve 48 is energized.
- the plunger assembly also referred to as a plunger. While moving plunger assembly 160 slides in an environment that is flooded with fluid (mud). The presence of mud allows plunger assembly 160 to slide back and forth with relative low friction.
- Sleeve member 66 includes a first end section 134 and a second end section 135.
- First end section 134 may include a plurality of threads 137 that engage first body portion 62.
- Second end section 135 may be mechanically linked to second body portion 64 through, for example, a press fit, a threaded connection, or a joining process such as welding.
- Sleeve member 66 includes an annular flange 140 extending radially inwardly from an inner surface (not separately labeled). Annular flange 140 together with housing 128 may define a plunger support 144.
- Sleeve member 66 may be formed from a high strength, non-magnetic material, such as steel or Inconel so as to withstand downhole fluids. Of course, it should be understood, that the particular materials employed for solenoid carrier 114, and sleeve member 66 may vary depending on desired operating parameters and downhole conditions.
- CVA 48 includes a plunger assembly 160, also referred to as a plunger, including a valve portion 162 and an actuator shaft 164, also referred to as a drive portion of the plunger.
- Valve portion 162 is operatively connected with actuator shaft 164.
- Actuator shaft 164 may be formed from soft magnetic material.
- Valve portion 162 may be formed from hard abrasion resistant material such as Tungsten Carbide and may be provided with a diamond coating of may employ other processes to form a hardened outer surface. The use of hard abrasion resistant material allows valve portion 162 to withstand high pressure corrosive and abrasive downhole mud passing from MVA 50 at high downhole temperatures as will be discussed more fully below.
- Valve portion 162 includes a central chamber 167 fluidically connected with first passage portion 72.
- a fifth passage portion 169 and a sixth passage portion 170 extend through valve portion 162.
- a spring 174 biases plunger assembly 160 in a first position as shown in FIG. 3 , wherein fifth and sixth passage portions 169 and 170 register with third and fourth passage portions 100 and 101 (control valve open position).
- Solenoid 120 is selectively activated to shift plunger assembly 160 to a second position ( FIG. 4 ) wherein fifth and sixth passage portions 169 and 170 are offset from third and fourth passage portions 100 and 101 (control valve closed position).
- CVA 48 may also include a washout passage 180 that provides passage for particles to be guided out from a back side (not separately labeled) of actuator shaft 164.
- Plunger support 144 may be either incorporated into or abutting on housing 128.
- Plunger support 144 is formed from a magnetic material, e.g. a soft magnetic material, and is part of the magnetic circuit.
- Plunger support 144 slidingly supports plunger assembly 160 by slidingly supporting actuator shaft 164.
- third and fourth passage portions 100, 101 and fifth and sixth passage portions 169,170 may extend at an angle of between about 20° and about 80° relative to a longitudinal axis (not separately labeled) of CVA 48.
- third and fourth passage portions 100, 101 and fifth and sixth passage portions 169,170 may extend at an angle of about 60° relative to the longitudinal axis. In this manner, shifting plunger assembly 160 between the first position and the second position shears mud flow passing from first passage portion 72 through valve portion 162 into mud flow outlet chamber 86. Further, with this arrangement, the amount of force necessary to shift plunger assembly 160 is reduced over that which would be needed if third, fourth, fifth and sixth passage portions 100, 101, 169, and 170 projected substantially perpendicularly relative to the longitudinal axis.
- second passage portion 74 may extend at an angle of between about 20° and about 80° relative to a longitudinal axis (not separately labeled) of CVA 48. In accordance with another aspect, second passage portion 74 may extend at an angle of about 60° relative to the longitudinal axis. The angle of second passage portion 74 reduces impact forces associated with pulses of mud passing from mud flow outlet 78 onto inner surface 40 may be reduced over those which would be realized if mud flow outlet 78 extended perpendicularly to the longitudinal axis.
- alternator assembly 46 provides signals to selectively activate, e.g., energize through an application of electric energy, solenoid 120 creating a magnetic flux 200 in a magnetic circuit (not separately labeled) that flows through second body portion 64, actuator shaft 164, plunger supports 144, and housing 128.
- the magnetic circuit includes a gap 171 between actuator shaft 164 and axial end 110 of solenoid support 108.
- magnetic circuit defines a pathway of material within CVA 48 through which magnetic flux 200 will flow.
- Activating solenoid 120 causes a magnetic field (not separately labeled) across the gap 171.
- the magnetic field creates a magnetic force that acts across gap 171 causing plunger assembly 160 to move toward second body portion 64. More specifically actuator shaft 164 moves toward solenoid support 108 thereby shifting plunger assembly 160 from the first position ( FIG. 3 ) to the second position ( FIG. 4 ). Plunger assembly 160 moves along a longitudinal axis of the body towards solenoid support 108 narrowing gap 171. Gap 171 need not fully close in order to close the control valve.
- Solenoid 120 may then be de-activated opening (interrupting) the magnetic circuit cutting off magnetic flux 200 allowing spring 174 to bias plunger assembly 160 back to the first position, opening the control valve.
- the width of gap 171 is larger than the width of gap 171 in the second position.
- the first position is also referred to as a gap open position
- the second position is also referred to as a gap closed position.
- the gap closed position does not require that the gap to be fully closed..
- mud may flow from MVA 50, through plunger assembly 160, into mud flow outlet chamber 86 and be expelled from mud flow outlets 78.
- MVA 50 creates mud pulses that travel through downhole string 20.
- An uphole receiver captures pressure waves created by the pulses of mud.
- the pressure pulses are presented in a pattern dictated by signals received from one or more sensors at alternator assembly 46.
- the pressure pulses may be decrypted to provide data regarding one or more downhole parameters to uphole operators.
- the valve portion 162 does not need to be made from magnetic material.
- the valve portion may be made from a material that is much better suited to withstand harsh downhole conditions, like high temperatures and corrosive and abrasive downhole fluids.
- the material of the valve portion of the plunger assembly may be high strength non-magnetic material, such as hardened steel, diamond, tungsten carbide, carbon nitride, or boron nitride or alternative hard and/or less corrosive material.
- the valve portion may as well be coated by a hard material, such a diamond coating.
- the teachings of the present disclosure may be used in a variety of well operations. These operations may involve using one or more treatment agents to treat a formation, the fluids resident in a formation, a wellbore, and/or equipment in the wellbore, such as production tubing.
- the treatment agents may be in the form of liquids, gases, solids, semi-solids, and mixtures thereof.
- Illustrative treatment agents include, but are not limited to, fracturing fluids, acids, steam, water, brine, anticorrosion agents, cement, permeability modifiers, drilling muds, emulsifiers, demulsifiers, tracers, flow improvers etc.
