Background technology:
Along with the development of China Petroleum, the Oil/gas Well of the harsh working conditions such as deep-well, ultra deep well, hyperbar well is more and more, and these wells are more and more higher to the Performance and quality requirement of oil country tubular goods, also in the urgent need to developing the novel tube of how applicable different well ' s conditions.In the novel tube research and development, in order accurately to reflect tubing service condition and inefficacy operating mode, the evaluation of science goes out ultimate bearing capacity and the applicability of tubing, need to set up a set of full-scale combined load Experiments of Machanics system, for simulating the real load condition, comprise the single or combined loads such as interior pressure, external pressure, tensile and compress, transverse force and temperature.100 meters its temperature of the every decline of depth of stratum raise 3 ℃ according to data, (especially deep-well, ultra deep well) not only will bear tensile, compressive, bending song and inside and outside compressive load effect so tubing is in down-hole, and environment temperature is also to affect the safe key factor of tubing military service; Temperature is less on the research of pipe performance impact in being on active service at present, do not have a set of theoretical system can illustrate accurately that temperature, on be on active service the safely impact of performance of tubing, therefore must adopt the actual loading test of simulating the realistic well condition condition pipe performance is estimated and verified.Yet the combined loading test system of having applied both at home and abroad at present, only can complete the external pressure combined load experiment of tubing under normal temperature condition; Applying always of high ambient conditions can't realize, for this type of shortcoming, for reflecting more accurately the actual duty status of tubing, this experimental system has been researched and developed a kind of experimental provision that can estimate tubing pipe performance under high temperature, external pressure combined load condition.
The utility model content:
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of device of External Pressure at High Temperature for the full-scale evaluation of oil country tubular goods is provided, can simulate the duty status of tubing while bearing high temperature and external pressure condition in down-hole, test out accurately relevant test figure, for the military service of tubing provides safeguard safely, improve the simulated experiment kind of tubing military service operating mode.
In the compound loading experimental system of prior art, only can complete the external pressure test under tubing normal temperature, with the actual duty status of tubing difference to some extent, for overcoming the deficiencies in the prior art, simulate more accurately, estimate the actual duty status of tubing in down-hole, set up and can to tubing, apply the test unit of temperature and external pressure condition, comprised (high temperature and high pressure) kettle, snap ring, (high temperature and high pressure) seal assembly, heating system and medium compress cell.The utility model patent can be simulated the evaluation test of tubing at the pressure and temperature working condition simultaneously, and simulation tubing Service Environment condition more true to nature effectively raises the accuracy of tubing evaluation experimental.
The purpose of this utility model solves by the following technical programs:
A kind of device of External Pressure at High Temperature for the full-scale evaluation of oil country tubular goods, comprise kettle, baffle plate, snap ring, seal assembly, pressing plate, induction heating equipment and medium compress cell, described kettle two ends are provided with end cap, between end cap and kettle, be connected with high-strength bolt, seal assembly is looped around the sample outer wall; Between described kettle and medium compress cell, be connected with high-pressure hose, on the kettle surface, be wound with induction heating flexible cord circle, induction heating flexible cord circle is connected with induction heating equipment.
Described External Pressure at High Temperature device also comprises strain testing unit and strain acquirement unit, on kettle, is provided with the signal wire outlet; Described signal wire outlet is connected with the strain acquirement unit with the strain testing unit.
Described baffle plate, seal assembly, snap ring and pressing plate are connected successively by hexagon socket head cap screw.
Described baffle plate, seal assembly, snap ring and pressing plate are looped around specimen surface, and float at the kettle internal freedom.
Described kettle closely is connected by high-strength bolt with end cap.
The working temperature of described External Pressure at High Temperature device is up to 260 ℃.
The working pressure of described External Pressure at High Temperature device is up to 300MPa.
With existing test unit, compare, the utility model has the advantages that:
1. existing experimental provision only can complete the external pressure experiment under normal temperature, and with the actual duty status of tubing difference to some extent, the External Pressure at High Temperature test of this test unit is more near the actual military service operating mode of tubing in down-hole.
2. this experimental provision also can complete the experiment under normal temperature external pressure condition, and high-temperature seal ring use at normal temperatures has the longer life-span than original normal temperature O-ring seal.
3. the high-temperature seal ring of this experimental provision bears high pressure and high temperature load simultaneously, and its deflection is very large, and the structural design of snap ring has effectively avoided high-temperature seal ring due to the damage that the distortion extruding causes, and has increased the serviceable life of high-temperature seal ring, provides cost savings.
