Abstract
The utility model relates to a corrosion detection device in the field of petroleum and natural gas exploration and development, in particular to a hanging piece device for oil pipe internal corrosiontesting, which is characterized in that a bush (4) is arranged in a shell (1) in a sheathing way, two ring hanging pieces (3) are arranged in the bush (4) in a sheathing way, the two ring hanging pieces (3) are located and isolated by a clamp ring (2), and a backing ring (5) is used to fix the hanging pieces (3) and the bush (4) on the inner wall locating platform of the shell (1). The device canbe installed under the well at any depth to detect the corrosion of the inner wall of the oil pipe, and the detected corrosion rate of the inner wall of the oil pipe is relatively exact.
Description
Technical field
The utility model relates to petroleum natural gas exploration field corrosion checkout gear, especially a kind of oil pipe internal corrosion test lacing film device.
Background technology
Along with the development of petroleum natural gas exploration, the environment that oil-gas mining faces is more and more abominable, makes that the etching problem of oil pipe is also more and more outstanding.The working environment of oil pipe is very abominable, and its application life and performance have a strong impact on exploration and development and oil gas field effectiveness of operation, also might cause serious accident and environmental problem.So tube corrosion speed becomes the focus that the related personnel pays close attention to, need a kind of monitoring device that can relatively truly reflect the tube inner wall corrosion rate.
Summary of the invention
The purpose of this utility model provides a kind of oil pipe internal corrosion test lacing film device, and this device can truly reflect pipeline corrosion speed.
The purpose that the utility model relates to is to realize like this, a kind of oil pipe internal corrosion test lacing film device is characterized in that: be with lining in housing, be with annular lacing film in the lining, isolate by the snap ring location between two lacing films, gasket ring is fixed on lacing film and lining on the inner walls positioning table.
The annular lacing film of cover is equidistant distribution in the described lining.
The described inner walls gasket ring one end outside is an internal thread; Housing other end outer wall is an external screw thread.
Described lacing film material is and tested oil pipe identical materials.
Characteristics of the present utility model are: this device lacing film is annular lacing film, and by the plastic bushing insulation, lacing film is by plastic clasp location and insulation between housing and the lacing film.Housing one end is that male thread one end is a box thread, is threaded onto on original oil pipe string by the housing two ends.This device is to be installed at any depth detection tube inner wall corrosion in down-hole situation, and can relatively truly detect the tube inner wall corrosion rate.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is an example structure schematic diagram of the present utility model.
Among the figure: 1, housing; 2, snap ring; 3, lacing film 4, lining; 5, gasket ring.
The specific embodiment
Accompanying drawing is non-limiting to disclose a specific embodiment of the present utility model, below in conjunction with accompanying drawing the utility model is further described.
Embodiment as shown in Figure 1, this oil pipe internal corrosion test lacing film device can detect tube inner wall corrosion situation, it is made up of housing 1, snap ring 2, lacing film 3, lining 4, gasket ring 5, in housing 1, be with lining 4, be socketed with several annular lacing films 3 in the lining 4, what of annular lacing film 3 are according to sampling needs decision, and general annular lacing film 3 is equidistant distributions, and lacing film 3 adopts the J55 materials to be used to detect tube inner wall corrosion situation.The material of general lacing film 3 is identical with tubing material, so the oil pipe of different materials adopts the lacing film 3 of different materials, adopts J55 or N80 material usually.Isolate by snap ring 2 location between each lacing film 3, snap ring 2 employing plastic materials are used for locating isolates and insulation.Lacing film 3 passes through lining 4 isolated insulations with housing 1 inwall, and gasket ring 5 is limited to lacing film 3 and lining 4 on the housing 1 inwall positioning table.Housing 1 inwall gasket ring 5 one ends outside internal thread; Housing 1 other end outer wall is an external screw thread.Thread standard can adopt the API standard.(API is an American Petroleum Institute (API))
Oil pipe internal corrosion test lacing film device is threaded on detected original oil pipe string by two ends, lining 4 and tubing nipple housing 1, and snap ring 2 and lining 4 are tight fit between lacing film 3 and the lining 4; Lacing film 3 internal diameters, housing 1 internal diameter, snap ring 2 internal diameters should be identical with original pipe aperture.
Oil pipe internal corrosion test lacing film device can be installed on the oil pipe string of the selected degree of depth of any degree of depth in down-hole, detects different depth place corrosion situation, takes out the lacing film inspection after a period of time and can draw corrosion rate according to relevant criterion again putting into the down-hole.
