Definitions

  • the present invention relates to a flow control screen for use in oilfield exploitation.
  • flow control screens are generally used for flow control, sand control or filtering of manually filled particles, etc. in an oil well, a gas well, a horizontal well, a vertical well and a directional well.
  • a screen comprises a base pipe, a through-bore being formed on the base pipe as the inlet of the base pipe, a filter pipe being sleeved over the base pipe, and an annular gap between the base pipe and the filter pipe acting as a flow guide layer.
  • Pall Well Technology came on the market with a new well screen under the trademark STRATAPACTM DOWNHOLE MEMBRANES.
  • the screen includes an inner perforated base pipe covered by a drainage mesh, which, in turn is covered by four layers of Pall PMM® medium, which is described as being stainless steel powder sintered with a pore structure of stainless steel woven wire mesh.
  • Pall PMM® medium which is described as being stainless steel powder sintered with a pore structure of stainless steel woven wire mesh.
  • This screen is described in U.S. Pat. No. 4,436,635, issued Mar. 13, 1984 , entitled “Porous Metal Article and Method of Making". Also, U.S. Pat. No. 4,858,691, which issued Aug.
  • US5823260 discloses a flow control screen for use in oilfield exploitation, comprising:a base pipe and a filter pipe sleeved over the base pipe such that an annular gap between the base pipe and the filter pipe forms a flow guide layer in which fluid is allowed to flow. Due to the factors such as the viscosity of water being much less than that of oil and formation heterogeneity, the problem of water production in the oil well is very severe in oil production, which seriously influences the economic efficiency of oil field.
  • a flow control screen provided with an axial seal for an oil field is an effective solution to the problem of huge water production caused by reasons like high oil water viscosity ratio in oil reservoir.
  • an effective flow control screen has been provided, wherein a flow control device is arranged in the screen, the inlet of the flow control device being in communication with the flow guide layer, and the outlet of the flow control device being in communication with the inlet of the base pipe.
  • the filter pipe is isolated from the exterior at both ends by the end rings of the screen, such that the fluid can enter the flow guide layer through the filter pipe only.
  • the fluid sequentially passes through the filter pipe, the flow guide layer, the inlet of the flow control device, the flow control channel of the flow control device, the outlet of the flow control device, the inlet of the base pipe, and finally the base pipe in the oil production process.
  • This is the only path, and except for it, there is no other path for the fluid to flow into the base pipe from outside of the screen.
  • This type of flow control screens function to reduce the flow difference per meter to some extent, thereby achieving the purpose of flow control. It can solve the problem of huge water production caused by reasons like high oil water viscosity ratio in oil reservoir, and non-uniformity of the flow per meter along the well bore during the process of water injection, the process of chemical injection, and so on.
  • the gap of the flow guide layers in the screen is very small, which is usually about 1 to 10mm, and however, the flowing length of the crude oil in the flow guide layer during oil recovery can be up to 4 to 9 meters and the flowing resistance of the crude oil in the flow guide layer is relatively greater. Whether the flow guide layer is unobstructed or not directly influences the oil production.
  • the filter pipe has two forms: one is to evenly distribute the longitudinal ribs on the external surface of the base pipe, and then wrap wires externally around the base pipe to form the filter pipe, which requires a dedicated precise wrapping machine which is costly; the other is to use a metal mesh jacket as the filter pipe, wherein the metal mesh jacket is lined with an inner protection sleeve with a plurality of holes, and the metal mesh jacket and the inner protection sleeve are sleeved over the base pipe with longitudinal ribs.
  • this method uses more materials.
  • the speed of mounting ribs is slow, and the size of mounting ribs is not standard and has large errors, which results in a large error about the outer diameter of the base pipe with longitudinal ribs and increases difficulty in sleeving the filter pipe.
  • An object of the present invention is to overcome at least one defect of a flow control screen in the prior art and to provide a flow control screen with fixed-supports on the inner wall of a filter pipe.
  • a further object of the present invention is to make the flow control screen simply structured and cost-effective, greatly simplify the manufacturing process and facilitate control of the quality in machining, and the flow guide layer is not closed due to the increased pressure around the screen in the formation to be kept unobstructed, and the problem of huge water production caused by reasons like high oil water viscosity ratio in oil reservoir during oil exploitation can be solved, thereby meeting actual requirements in oil production.
  • the present invention provides a flow control screen used in oilfield exploitation, comprising:
  • the at least one fixed-support comprises a plurality of fixed-supports, and the plurality of fixed-supports are substantially uniformly distributed on the inner wall of the filter pipe (or on one side of the metal pipe). It shall be appreciated by those skilled in the art that since the filter pipe is made of the metal plate and the fixed-supports are usually not disposed adjacent to the boundary of the metal plate, there are no fixed-supports in proximity of the joint on the wall of the filter pipe after formation of the filter pipe using such a metal plate.
  • each of the fixed-supports is a protruding part fixed to the inner wall of the filter pipe, and the height of each of the protruding parts is set to ensure that the flow guide layer is not closed under the external pressure around the screen in the formation.
  • each of the fixed-supports is a protruding part inwardly punched on the wall of the filter pipe, and the punching depth of each of the protruding parts is greater than the thickness of the wall of the filter pipe so that the slots are formed in the form of sidewise-slots between portions of the periphery of the top surface of each of the protruding parts and the shearing planes of the unpunched portions of the wall of the filter pipe.
  • the top surface of each of the fixed-supports is substantially in the shape of quadrangle. More preferably, the top surface of each of the fixed-supports is substantially in the shape of square or rectangle.
  • the top surface of each of the fixed-supports is substantially in the shape of square or rectangle, and the slots are formed in the form of sidewise-slots between two opposite side edges of the top surface of each of the fixed-supports and the shearing planes of the unpunched portions of the wall of the metal pipe.
  • each of the slots is configured to extend parallel to the longitudinal axis of the filter pipe, or each of the slots is configured to extend at an angle with respect to the longitudinal axis of the filter pipe, the angle being greater than 0 degree but not more than 90 degrees.
  • the plurality of slots comprise a plurality of groups of slots, the distribution pattern of which is made such that the slots in each group are equidistantly distributed in the circumferential direction of the filter pipe, and the groups of slots are equidistantly distributed in the longitudinal direction of the filter pipe; or the slots in each group are equidistantly distributed in a spiral direction on the wall of the filter pipe, and the groups of the slots are equidistantly distributed in the circumferential direction of the filter pipe.
  • the filter pipe is a metal pipe formed by welding a spirally wound elongated metal plate preformed with the fixed-supports.
  • the flow control screen of the present invention is simple in manufacturing process and cost-effective, wherein the fixed-supports are disposed on the inner wall of the metal filter pipe which is provided with the slots, the fixed-supports can be formed by means of punching on the metal plate, or directly disposed on the metal plate by means such as welding or adhesion.
  • the fixed-supports are arranged on a piece of elongated metal plate, and the filter pipe is formed by wrapping inwardly and spirally the face of the metal plate with the fixed-supports and then welding the resultant face into a cylinder. After the filter pipe is sleeved over the base pipe, the inwardly protruding fixed-supports function as longitudinal ribs in the flow guide layer between the filter pipe and the base pipe.
  • the fixed-supports When the filter pipe is pressed under external pressure, the fixed-supports exert a supporting function such that the flow guide layer is not closed with the increased external pressure, thereby keeping the flow guide layer unobstructed.
  • the slots are configured to meet the requirements on filtering precision of the screen. Since the filter pipe is made of the metal plate, such a filter pipe has a superb overall strength and anti-deformation capacity.
  • the supporting function of the inwardly protruding fixed-supports makes the flow guide layer unobstructed, reduces the flow resistance of the crude oil in the flow guide layer, and is in favor of increase in oil production.
