Description
Technical field
The present invention relates to a kind of cleaning devices, more particularly, to a kind of pollution-free high temperature nitrogen washing and cleaning operation method of pumpingh well
And device.
Background technique
Oil well light maintenance operation is oilfield servicing production, the core means for taking well stimulation.Oil pipe inside and outside wall, sucker rod
Cleaning is most basic, most critical a ring；Oil pipe and sucker rod wax deposition, scale formation are extremely serious in oilfield exploitation, so that
Oil flow channel gradually becomes smaller, or even blocks, and causes oil well output to reduce or even stop production, there is a situation where serious wax deposition, fouling
Under, since oily overpressure increases, the load of downhole pump can be also aggravated, shortens the service life of oil well pump, influences oil well
Normal production, thus the quality of oil pipe and sucker rod cleaning quality generates important influence to subsequent handling, and then influences oil
The quality of pipe use cost and construction operation.The selection of cleaning way directly affects the cleaning effect, production cost, reparation of oil pipe
Quality, the safety of operation.
Currently, the cleaning operation technology of maintainability light maintenance operation process develops slower, each oil field routine light maintenance operation
Mode is distinguished less, and following four kinds of cleaning ways are mainly taken:
1, water-boiling method: water-boiling method is traditional cleaning way, and which is to impregnate the oil pipe recycled from oil well in pond,
Sufficient chemical is added, is heated by boiler and carries out boiling, to wash the greasy dirt and silt of oil pipe inside and outside wall, the party
The advantages of formula is that equipment is simple, and easy to operate, one-time investment is few.But there is also some disadvantages, are mainly shown as: (1) cleaning
Agent is formulated using highly basic or strong acid and other organic chemicals, is damaged greatly to oil pipe, causes oil pipe inside and outside wall anti-
Rotten layer large area falls off, and oil pipe is made to lose good protection.After coming into full contact with air, oil pipe inside and outside wall will form more serious
Corrosion, eventually leads to oil pipe and scraps；(2) environmental pollution is serious.The gas that one side cleaning agent distributes can damage people；Separately
On the one hand, the sewage after cleaning inside service sink recycles difficult, will cause environmental pollution；(3) large labor intensity.When cleaning, need
Oil pipe is lifted up into from pond and is hung out, if oil pipe quantity is big, workload can be multiplied；(4) at high cost.Traditional tubing repair
It is cleaned with high grease soil detergent, it is expensive, in addition cost of labor, causes rehabilitation cost excessively high.
2, heating in medium frequency method: heating in medium frequency method is the technology of the cleaning newly used recent years, adjusts electricity using frequency converter
Source frequency carries out transient heating to oil pipe to be repaired, melts the greasy dirt of oil pipe surfaces externally and internally to be repaired and wax deposition comprehensively, then
The greasy dirt of the inside and outside thawing of pipe and wax deposition are removed substantially with oil-scraping device, then cleaned by wire brush in rotation, finally
The inside and outside wall residue of oil pipe to be repaired is rinsed well with the water flow with certain pressure.The shortcomings which, is: (1) heating
When, the oil flue waste gas that the sundries such as greasy dirt generate is big, and it is seriously polluted, human and environment is impacted；(2) it is easy to happen fire；(3)
The temperature of heating is not easy to determine, temperature is too high to generate destruction to oil pipe ontology metallographic structure, and temperature is too low not to have heating
Effect.
3, high pressure water rinses: high pressure water flushing is an emerging cleaning technique, is generated with high-pressure plunger pump and nozzle high
Fast water jet, powerful impact force directly wash away tube inner wall foulant, dirt are made to fall off, and reach cleaning purpose.Which
The disadvantage is that: (1) pressure in cleaning generated is very big, and very big danger can be formed to operator；(2) nozzle is vulnerable part,
It needs to be replaced frequently, working efficiency is low；(3) water consumption is very big, causes great energy consumption.
4, direct-burning heating oil pipe water cleans: using burning natural gas as heat source, hot water inside circulation, whole device realization
The one-stop cleaning of oil pipe sends out oil pipe finally by output system.The shortcomings that cleaning way, is: once device internal mechanical
Running part breaks down, and maintenance time is longer；
Above-mentioned conventional mechanical wax removal descaling method not only less effective, but also influence oil well output, chemical wax removal cost is higher, heat
Carrier cleans that cost is excessively high, and the thermal efficiency is low, and the flushing fluid used is more, and the drainage period that drives a well was at three days or more, and to sensibility
Oil reservoir will cause injury, and conventional clean mode has equipment more in a word, and energy consumption is high, and low efficiency, exhaust emission is big, task difficulty
Greatly and the heavy drawback of cleaning task afterwards.
In addition, a large amount of crude oil takes well head out of after crude oil landing with rod string and causes dirt during carrying out wax removal
Contaminate natural environment, waste of resource, currently in cleaning tubing on well site or sucker rod would generally ground be laid with barrier material,
The excessive cofferdam of anti-grease is built, the safeguard procedures such as Oil Guide ditch, recovery pond are set in construction area, these conventional safeguard procedures
It cannot fundamentally solve the problems, such as that operation process grease does not land, the pollution problems such as resulting oil soil, plastic cloth are very
It is prominent, financial burden and environmentally friendly risk are caused to construction both sides.
