Description
Technical field
The utility model relates to a kind of high temperature screen casing test unit, particularly a kind of high temperature screen casing thermal expansion coefficient testing device.
Background technology
In recent years, hydrocarbon resources demand increased year by year fast, and conventional gas and oil has been difficult to satisfy the demands, belonged to the thickened oil recovery development of unconventionaloil pool rapidly.Viscous crude mainly adopts high-temperature steam to carry out thermal recovery, temperature reaches more than 300 DEG C, oil well will stand the temperature cycles of high temperature and many rounds in process of production, the high-temerature creep existed and alternating thermal stress load affect larger on tubing string, the Bohai Bay Oil of China, Xinjiang Oilfield, Viscous Oil Well In Liaohe Oilfield tubing string well damage, screen casing particularly long horizontal well sieve tube produce flexing owing to being subject to large Axial Thermal stress loading, the inefficacy such as to break, had a strong impact on safety and the output of oil well.Existing solution links thermal stress compensator in screen casing tubing string, alleviates or eliminate the Axial Thermal stress that screen casing is subject to.This rooting will calculate the performance requirement of thermal stress compensator and usage quantity according to the thermal expansivity of screen casing.And screen construction is complicated, of a great variety, the thermal expansion coefficient difference of different screen casing is comparatively large, can only carry out Accurate Measurement by test.Because screen casing sample is longer and there is high temperature, conventional method of pasting foil gauge is difficult to meet the demands.
Utility model content
The purpose of this utility model is to provide a kind of structure simple high temperature screen casing thermal expansion coefficient testing device, for testing screen casing sample thermal expansivity under the high temperature conditions.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of high temperature screen casing thermal expansion coefficient testing device, comprise two L-type support, two L-type support are separately fixed at two ends of screen casing base tube to be tested, two L-type support are all vertical with screen casing longitudinal center line, extensometer two ends are connected with the L-type support being fixed on screen casing base tube two ends to be tested respectively by wire rope, wire rope and screen casing axial centerline parallel.
Described two L-type support are all clamped to two ends of screen casing base tube to be tested by pressing plate and bolt.
Described extensometer two ends are connected with wire rope one end respectively, and the wire rope other end is fixed in L-type support by fixator.
One end that described wire rope is connected with L-type support is connected with threaded rod, and L-type support offers through hole, and threaded rod is fixed through through hole nut.
The distance of described extensometer and one of them L-type support is no more than 300mm.
First L-type support is fixed on screen casing base tube end during use, L-type support is regulated to make it vertical with screen casing longitudinal center line, then extensometer two ends are connected with two wire rope respectively, finally respectively the two wire rope other ends are fixed in the L-type support of screen casing base tube both sides, L-type support is regulated to make wire rope and screen base line parallel, by the deformation of extensometer test screen casing at length direction in high temperature, to obtain the thermal expansivity of screen casing; The utility model structure is simple, and easy for installation, production cost is low, and applied range is with a wide range of applications.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1-screen casing base tube; 2-screen casing filter net cloth; 3-fixator; 4-L type support; 5-bolt; 6-pressing plate; 7-wire rope I; 8-extensometer; 9-wire rope II.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further, the embodiment provided only in order to illustrate the utility model, instead of in order to limit scope of the present utility model.
As shown in Figure 1, the utility model is made up of L-type support 4, fixator 3, bolt 5, pressing plate 6, wire rope I 7, wire rope II 9 and extensometer 8 etc., two L-type support 4 are separately fixed at two ends of screen casing base tube 1 to be tested, two L-type support 4 are all vertical with screen casing longitudinal center line, extensometer 8 one end is connected with wire rope I 7, the other end is connected with wire rope II 9, wire rope I 7 and wire rope II 9 other end are fixed in the L-type support 4 at screen casing base tube 1 two ends to be tested by fixator 3, wire rope and screen casing axial centerline parallel.
For convenience of installing, two L-type support 4 are all clamped to two ends of screen casing base tube 1 to be tested by pressing plate 6 and bolt 5, one end that wire rope I 7 is connected with L-type support 4 with wire rope II 9 is connected with threaded rod, L-type support 4 offers through hole, threaded rod is fixed through hole nut, by adjusting nut position, wire rope is strained, make wire rope I 7 hang down parallel with wire rope II 9 with screen base line.Extensometer 8 is no more than 300mm with the distance of one of them L-type support 4.In the L-type support that the design of screen casing two ends is long, the impact of extensometer away from high temperature screen casing not by temperature can be made, ensure that accuracy and the reliability of experimental test.
The utility model structure is simple, easy for installation, can complete the thermal expansivity test job of screen casing fast, provides a kind of simple and feasible test mode, improves test job efficiency.
