Abstract
The utility model discloses a spiral efficiency-improving heating tube for a heavy oil well test. The spiral efficiency-improving heating tube is characterized by being mainly composed of a heavy oil conveying pipe, a spiral partition plate and a sleeve, the spiral partition plate is wound around the periphery of the heavy oil conveying pipe, the sleeve is installed on the periphery of the spiral partition plate in a sleeved mode, a hot water inlet is formed in the portion, close to one end of the sleeve, of the wall of the sleeve, a hot water outlet is formed in the portion, close to the other end of the sleeve, of the wall of the sleeve, and a spiral water flow channel is formed by the heavy oil conveying pipe, the sleeve and the spiral partition plate in a defined mode. By the adoption of the structure form, the temperature of ground heavy oil can be raised in the conveying process, the viscosity of the heavy oil is reduced, conveying resistance is reduced, successful completion of heavy oil well test operation is guaranteed, and therefore the spiral efficiency-improving heating tube has wide application and popularization prospects; because a plurality of turbulence excitation protrusions are distributed on the spiral partition plate, hot water is affected by the turbulence excitation points to generate turbulence, heat is continuously exchanged in the hot water, and the heat exchange efficiency of the heating tube is further improved.
Description
Technical field
The utility model relates to Oil/gas Well formation testing field, particularly
a kind ofthick oil well test spiral synergy heating pipe.
Background technique
Sea environment-friendly requires day by day to improve at present, Offshore Heavy Oil Field prospect pit test jobs production fluid cannot burn, and owing to there is no production platform as support, need to be transferred to environment protection ship by flow process, by environment protection ship, be transported to periphery production platform again, through flow process, be injected into production system.Current test line does not have heating function, and viscous crude temperature in ground flow declines rapidly, and viscosity raises fast, and partial coagulation is put after high viscous crude goes out well and even solidified, and cannot flow completely.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of thick oil well test spiral synergy heating pipe is provided.Raise when the carrying temperature of ground viscous crude of the utility model, reduces viscosity of thickened oil, reduces transporting resistance, completing and providing safeguard smoothly for thick oil well test jobs.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of thick oil well test spiral synergy heating pipe, it is characterized in that: it mainly consists of heavy oil transportation pipe, spiral septum and sleeve pipe, spiral septum extends around the peripheral of heavy oil transportation pipe and along the axial direction of heavy oil transportation pipe, casing pipe sleeve is contained in the periphery of spiral septum spiral septum, on the tube wall of sleeve pipe and one end of close sleeve pipe is provided with hot water inlet, on the tube wall of sleeve pipe and near the other end of sleeve pipe, be provided with hot water outlet, heavy oil transportation pipe, sleeve pipe and spiral septum surround a spirality flow channel.
On described spiral septum, be distributed with a plurality of turbulent flows and excite projection.
Described a plurality of turbulent flow excites projection to be uniformly distributed on spiral septum.
The surface of described sleeve pipe is with thermal-protective coating.
The beneficial effects of the utility model: owing to adopting above-mentioned structural type, can raise when the carrying temperature of ground viscous crude, reduces viscosity of thickened oil, reduces transporting resistance, for the completing and provide safeguard smoothly of thick oil well test jobs, there is popularizing application prospect more widely; Owing to adopting the form of spiral septum, extended the heated time of heavy oil transportation pipe, heat energy is fully used; Owing to being distributed with a plurality of turbulent flows on spiral septum, excite projection, hot water is subject to the impact of turbulent shot point, produces turbulent flow, and exchange heat is constantly carried out in hot water inside, further improves the heat exchange efficiency of heating pipe.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, heavy oil transportation pipe; 2, spiral septum; 3, sleeve pipe; 4, hot water inlet; 5, hot water outlet; 6, turbulent flow excites projection; 7, thermal-protective coating.
Embodiment
As shown in Figure 1, a kind of thick oil well test spiral synergy heating pipe, it mainly consists of heavy oil transportation pipe 1, spiral septum 2 and sleeve pipe 3, spiral septum 2 extends around the peripheral of heavy oil transportation pipe 1 and along the axial direction of heavy oil transportation pipe 1, sleeve pipe 3 is sleeved on the periphery of spiral septum 2 spiral septums, and the surface of described sleeve pipe 3 is with thermal-protective coating 7.On the tube wall of sleeve pipe 3 and near one end of sleeve pipe, be provided with hot water inlet 4, on the tube wall of sleeve pipe 3 and near the other end of sleeve pipe, be provided with hot water outlet 5, heavy oil transportation pipe 1, sleeve pipe 3 and spiral septum 2 surround a spirality flow channel.On described spiral septum 2, be evenly distributed with a plurality of turbulent flows and excite projection 6.
Working principle: hot water inlet 4 is connected with hot-water heating system by aqueduct with hot water outlet 5, under the effect of pump, spirality flow channel aqueduct, hot-water heating system and pump form a hot water heating circulatory system, hot water is in the process of spirality flow channel of flowing through, viscous crude in heavy oil transportation pipe is heated, thereby reduce transporting resistance, completing and providing safeguard smoothly for thick oil well test jobs.
The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or is equal to replacement, do not depart from the protection domain of technical solutions of the utility model.
