Definitions

  • the invention relates to a fast valve actuator and a tool provided with this actuator.
  • One field of application of the invention relates to the valves intended to be installed in a subsurface operation pipe, for example in the oil or gas production wells and any eruptive well for taking hydrocarbons present in a the basement, or any injector well.
  • the production wells usually include an underground wall having bores for passing the produced fluid from the surrounding production layer into the well and then up to the surface due to the fluid pressure in that layer.
  • This production yield can be influenced by different parameters and conditions.
  • One of these parameters relating exclusively to the structure of the drilled well, is the cross section of fluid passage produced between the subsurface layer and the well wall. The larger this section of passage, the greater a quantity of fluid can be raised from the well.
  • This passage section may be polluted by materials and fluids such as drilling mud, casing cement, or solids carried by the fluid produced.
  • the pressure measurement curves must be used with regard to their value but also their slope ⁇ as a function of time t.
  • the duration T that the measured pressure P puts to pass from the production pressure P1 to the pressure P 2 of the deposit is it equal to a value of between half a day and ten days.
  • the pressure curve becomes assimilated, at least during the first phase immediately following closure or full opening, to a general first-order curve in response to a flow step at the valve, characterizing the instantaneous passage between its closed state and its open state or vice versa.
  • a steep slope of the curve of Figure 1 indicates a thin skin or a passage section slightly obstructed, providing a higher production yield.
  • the pressure response is similar to a curve of order greater than one, such as that shown in FIG. 2, in which the slope of the pressure as a function of time begins to increase to a point of deflection, and then to decrease, until that the pressure goes into steady state.
  • the measured pressure curve P it is much more difficult to exploit the measured pressure curve P, since it depends on a larger number of parameters than on the single pass section at the level of the production layer.
  • the measured pressure curve P can not be used during the TI time flowing to the point of inflection.
  • the aim of the invention is to obtain a valve actuator and a tool equipped with the actuator, which makes it possible to open and / or close the valve as quickly as possible between the last moment when the valve is located. completely in the open and / or closed state and the moment when the valve is completely in the closed and / or open state, so that the flow rate measured downstream of the valve is as close as possible to a step of flow as a function of time, so that the response to the actuation of the valve is as close as possible to the curve according to FIG.
  • a first object of the invention is a fast valve actuator according to claim 1.
  • the invention allows the rapid movement of the valve between the open or closed position and the closed or open position.
  • the actuator is able to cause several movements of opening and closing of the valve. It is thus possible to reassemble the valve and the tool comprising it in the open state after an opening movement or a closing movement followed by an opening movement, which was not possible with valves that can only perform one closure.
  • the actuator makes it possible to perform a quick opening and / or closing successively in several successive layers of well production.
  • the product fluid carries abrasive materials such as sand and passes through the valve with a very high speed.
  • This high speed is due to the large pressure difference between the upstream and downstream sides of the valve, which increases as the fluid passage gap in the valve narrows at the end of closing and at the beginning of opening.
  • the fluid produced has a tendency to be applied against the slide or the movable piston of the valve during its closing or opening movement.
  • the accumulation of energy in the actuator according to the invention also makes it possible to guarantee that the force exerted on the valve overcomes the resistance between its mobile part and its fixed part, which may be due to the bonding of the sealing means between those this, resulting from the high temperature and pressure conditions prevailing in the well. Consequently, the actuator and the tool comprising the actuator are more reliable.
