Description
Technical field
The present invention relates to oil field conveying technology fields more particularly to a kind of " cold adopt cold defeated " from producing well to measuring station to adopt
Fuel transfer system.
Background technique
Crude oil is given rise to well head below by oil pipe from oil well, and crude oil is then sent to oil field meter by ground petroleum pipeline
Amount station.
The oil well of exploitation largely uses deep well pump+plain tubing production method by land at present, and wellbore fluid exists
In lifting process, geothermal energy and pit shaft carry out heat exchange, and temperature constantly declines, and easily make tube inner wall wax deposition, thus shadow
Ring normal production.In order to enable producing can operate normally, and it is general using ribbon heater is added in hollow rod, it carries out electricity and adds
Heat, or periodically stop well and carry out hot clean-up well.It also needs that chemical agent is added in process of production simultaneously, delays wax deposition process.
It after liquid to well head, generally needs to heat, subsequently into ground petroleum pipeline.But since environment temperature declines, in pipeline
Crude oil be difficult to guarantee that the reliability of its quality, the viscosity of crude oil increase, flow velocity reduces, and influences the conveying of pipeline.Work as temperature
Phenomena such as when being reduced to crude oil freezing point or less, crude oil solidifies substantially, and the blocking of Chang Fasheng pipeline is even broken.Therefore, to pipeline
The heat preservation of Crude Oil is an extremely important job.Common heat preserving method has medium-frequency electrical heating and hotwater tracing's pipe, these
Require consumption energy.
Above-mentioned oil recovery, transmission process are known as " thermal recovery heat is defeated " by us.
Due to " thermal recovery heat is defeated ", it is necessary in view of the above technical problems, research and develop and new adopt transmission method.
Summary of the invention
The purpose of the present invention is problem in view of the prior art, a kind of " cold adopt cold defeated " from producing well to measuring station is provided
Adopt fuel transfer system.
The technical scheme adopted by the invention is that:
A kind of " cold adopt cold defeated " from producing well to measuring station adopts fuel transfer system, including sequentially connected deep well pump, oil pipe,
Thermal insulation tubing, thermal-insulating type ground petroleum pipeline and measuring station,
Wherein, the thermal insulation tubing is set to the downward 800m-1500m of well head, the downward connected pipes of thermal insulation tubing,
The temperature drop of thermal-insulating type ground petroleum pipeline is≤2 DEG C/km.
Further, the internal diameter of the original steel pipe of the thermal insulation tubing is 50mm-76mm.
Further, ribbon heater is built-in in the pipeline of thermal-insulating type ground petroleum pipeline.
Further, the temperature when length of the thermal insulation tubing is given rise to import by oil gas determines that oil gas gives rise to well
Temperature when mouth is higher than 5 DEG C of point of the well crude oil wax.
Beneficial effects of the present invention:
A kind of " cold adopt cold defeated " from producing well to measuring station disclosed by the invention adopts fuel transfer system, rationally using heat preservation oil
Pipe, makes full use of geothermal energy, so that not having to electric heating, dosing in oil recovery process.The electricity charge, expenses for medicine and its relevant device are saved
And human cost, especially greatly reduce frequent operating cost；
Ground uses thermal-insulating type continuous flexible pipe, and oil well produced next oil is sent to measuring station, enables to crude oil in well
Mouth is minimized to measuring station transmission process temperature drop.And it is brought great convenience using thermal-insulating type continuous flexible pipe to construction.
Present invention is further described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is existing conventional oil recovery, oil transportation flow chart.
Fig. 2 be the present invention " cold adopt cold defeated " recover the oil, oil transportation flow chart.
Specific embodiment
In order to deepen the understanding of the present invention, further details of theory is made to the present invention with reference to the accompanying drawings and examples
It is bright.The following examples are only intended to illustrate the technical solution of the present invention more clearly, and cannot be used as a limitation and limit guarantor of the invention
Protect range.
As shown in Fig. 2, a kind of " cold adopt cold defeated " from producing well to measuring station of the present invention adopts fuel transfer system, including successively connect
Deep well pump, oil pipe, thermal insulation tubing, thermal-insulating type ground petroleum pipeline and the measuring station connect,
Wherein, thermal insulation tubing is set to the downward 800m-1500m of well head, the downward connected pipes of thermal insulation tubing,
The temperature drop of thermal-insulating type ground petroleum pipeline is≤2 DEG C/km.
In the present invention, the internal diameter of the original steel pipe of thermal insulation tubing is 50mm-76mm.
In the present invention, ribbon heater is built-in in the pipeline of thermal-insulating type ground petroleum pipeline.
In the present invention, the temperature when length of thermal insulation tubing is given rise to import by oil gas is determined, when oil gas gives rise to well head
Temperature be higher than 5 DEG C of point of the well crude oil wax.
In the present invention, thermal-insulating type continuous flexible pipe can be intelligent, and ribbon heater can be placed in its pipeline, lead
It acts on and being, (such as have a power failure, extreme climate situation) after delivery pipe meets catastrophic failure and cause plugging, it is automatic when driving a well again
Start electric heating charged, it is ensured that pipeline gradually restores to operate normally.
In the present invention, collection petroleum pipeline is also possible to other heat preservation petroleum pipelines, can be outside the steel pipe except continuous flexible pipe
Bread covers the conventional petroleum pipeline of thermal insulation material, but temperature drop requires to control within the limits prescribed.
The present invention combines oil recovery energy conservation with surface gathering and transferring power-saving technology, while considering under case of emergency and (collecting defeated
Oil pipe has a power failure suddenly) using the prediction scheme of intelligent collection petroleum pipeline, it ensure that the unimpeded of oil transportation route.
Integrated technology of the present invention is to be adjusted from the deep well pump of producing well to the power-saving technology of measuring station whole process due to comprehensive
It saves, balance geothermal utilization technology, so that the scheme of " cold adopt cold defeated " is achieved.
Of the invention to adopt fuel transfer system slave " cold adopt cold defeated " of producing well to measuring station, i.e., " cold adopt cold defeated " adopts oil transportation side
Method passes through the setting of thermal insulation tubing and thermal-insulating type ground petroleum pipeline, it is ensured that does not have to electric heating, dosing in oil recovery process, equally
It may be implemented oil well produced next oil being sent to measuring station, saved the electricity charge, expenses for medicine and its relevant device and human cost, especially
Greatly reduce frequent operating cost.
It is noted that embodiment described above is the affiliated technology neck to the illustrative and not limiting of technical solution of the present invention
The equivalent replacement of domain those of ordinary skill or other modifications made according to the prior art, as long as not exceeding the technology of the present invention side
The thinking and range of case, should be included within interest field of the presently claimed invention.
