Abstract
The invention discloses a heavy oil well test spiral synergy heating pipe, which is characterized in that the heavy oil well test spiral synergy heating pipe mainly consists of a heavy oil delivery pipe, a spiral clapboard and a casing pipe, wherein the spiral clapboard is surrounded on the periphery of the heavy oil delivery pipe; the casing pipe is sheathed on the periphery of the spiral clapboard; a hot water inlet is arranged near one end of the casing pipe on the pipe wall of the casing pipe; a hot water outlet is arranged near the other end of the casing pipe on the pipe wall of the casing pipe; a spiral water flow channel is surrounded by the heavy oil delivery pipe, the casing pipe and the spiral clapboard. Due to the structural style, the temperature of ground heavy oil can be raised while the heavy oil is delivered, the heavy oil viscosity is lowered, the delivery resistance is reduced, the guarantee is provided for successfully finishing the heavy oil well test operation, and the heavy oil well test spiral synergy heating pipe has a wider popularization and application prospect. As a plurality of turbulence excitation bulges are distributed on the spiral clapboard, hot water is affected by turbulence excitation points to generate turbulence, heat is continuously exchanged in the hot water, and therefore the heat exchange efficiency of the heating pipe is further improved.
Description
Technical field
The present invention 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 object of the invention is to overcome deficiency of the prior art, a kind of thick oil well test spiral synergy heating pipe is provided.Raise when the carrying temperature of ground viscous crude of the present invention, 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 technical solution adopted in the present invention 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.
Beneficial effect of the present invention: 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 present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
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 the preferred embodiment of the present invention; certainly can not limit with this interest field of the present invention; should be understood that; for those skilled in the art; technological scheme of the present invention is modified or is equal to replacement, do not depart from the protection domain of technical solution of the present invention.
