Description
Technical field
During the utility model is related to oil field production, wax card releases technical field, is specifically exactly a kind of wax card well nitrogen speed
Degree hot fluid is excused from a college course well unfreezing system.
Background technology
Due to the impact of the crude oil content of wax, in oil well production process, crude oil from oil reservoir given rise to ground when, formation temperature
Constantly decline, paraffin is constantly separated out from crude oil and is attached on oil pipe and sucker rod, finally solidifies and block crude oil rising passway,
Simultaneously sucker rod cannot up and down or rotary motion --- wax card.
Wax card accident causes oil well crude oil rising passway to block cannot to produce, and stopping production has a strong impact on the economic benefit of oil well；
Workover treatment equipment will be gone up to resume production, due to sucker rod cannot operation rise, need to carry out sawing, cause oil pipe and
Sucker rod is scrapped and is increased well workover in a large number and safeguards the engineering time, causes workover treatment maintenance cost far above conventional well workover；In order to
Prevent such situation from oil well occurring and frequently hot wash, excess can only add Wax removing agent preventing and treating, this increases dosing expense and wax control again
Expense, even if thus, also continuously emerge wax card accident, have a strong impact on production run.Therefore a robust techniques are needed to process
Wax Ka Jing, reduces producing cost.
The content of the invention
The purpose of this utility model is to provide a kind of wax card well nitrogen speed hot fluid to be excused from a college course well unfreezing system, using height
Warm steam coordinates the speed hot fluid that nitrogen is formed to take heat to wax card division position, melts solid wax and eliminates wax card and recover oil well
Well unfreezing is excused from a college course in production realization.
The technical scheme in the invention for solving the technical problem is：A kind of wax card well nitrogen speed hot fluid is exempted from
Well workover unfreezing system, including the equipment of making nitrogen and steam generator, the described equipment of making nitrogen and steam generator are by connecting manifold
Connect and lead to well head upper end pressure manifold, the described equipment of making nitrogen provides high-purity nitrogen to solve the construction of paraffin removal card, prevents from containing
Oxygen air occurs inflammable and explosive with air-fuel mixture, there is provided the gas flow of enough flows, and the quick steam thermal energy that carries arrives at wax card
Position, prevents vapours flow velocity excessively slow, and described connection manifold is connected with wellhead assembly, described wellhead assembly and down-hole string
Connection, described wellhead assembly are controlled by head valve, realize that high-temperature steam coordinates the speed hot fluid that nitrogen is formed to enter
Down-hole, flows through wax card division position, melts paraffin, solves paraffin removal card.
Used as optimization, described steam generator provides enough heat energy to solve the construction of paraffin removal card, realizes high temperature melting paraffin,
Recover sucker rod pump lifting production system lifting production.
Used as optimization, the high-temperature steam that described steam generator is produced coordinates nitrogen to form speed hot fluid in fusing stone
Before wax, fluid enters reservoir, energy reserve, and after melting, Fluid pressure forces hot fluid to carry paraffin and migrates upwards, final to discharge
Pit shaft, takes ground to, returns row from stratum into reservoir hot fluid, on the one hand washes away elimination formation contaminant, on the other hand continues clear
Except paraffin in well, recover subsequent production.
The beneficial effects of the utility model are：Compared with prior art, a kind of wax card well nitrogen speed of the present utility model
Hot fluid is excused from a college course well unfreezing system, makes full use of steam to change into huge latent heat during water, and collaboration nitrogen gas preparing makes a large amount of nitrogen
Increase vapours flow velocity so that steam adds nitrogen speed hot fluid quickly to arrive at calorie position, quick dewaxing solution paraffin removal card system
It is reasonable in design, easy to implement, work well, heavy oil wells viscous crude unfreezing, gas well wax removal and hydrate de-plugging, oil gas can also be solved
Pipeline pipeline purging etc., has the advantages that low operating cost, energy-conserving and environment-protective and convenient, flexible.
