The analysis anti-sulphur of sulphur well head blocks up system
Technical field
The present invention relates to the anti-sulphur plugging technique fields of well head more particularly to a kind of analysis anti-sulphur of sulphur well head to block up system.
Background technology
At present, after the natural gas both at home and abroad in high sulfur-bearing gas recovery well is produced via christmas tree, often in conveying natural gas
Sulphur depositional phenomenon occurs in surface gathering and transferring pipeline and corresponding processing unit, so as to be easy to occur sulfur plug gathering line, section
Situations such as flowing valve, separator, directly influences the normal production of gas recovery well.
In order to solve the problems, such as above-mentioned sulfur plug, common method has at this stage:The stifled method of steam coach pyrolysis, high pressure gas are blown
Sweep method, sulphur solvent soaking method, sulfur elimination annotation method etc..Wherein, the stifled method of steam coach pyrolysis primarily directed to tamper it is smaller, block
The lighter pipeline of situation, heats block part using steam coach and is melted tamper, and plugging removal effect is preferable, but
Corrosion easily is generated to pipeline, equipment, especially temperature is relatively low in winter, and effect is undesirable under the larger environment of humidity.High pressure gas
Sweeping method has to stop production to gas recovery well, and blocking position is purged using the high pressure gas at blocking position rear portion, then
Coordinating with steam rapid heat cycle vehicle blows out the foreign matter of blocking position, time-consuming longer, ineffective.Sulphur solvent soaking method mainly for it is small-sized can
The equipment of dismounting carries out mechanical cleaning and immersion, can not be suitable for gathering line and large scale equipment device, while also need to gas production
Well stops production, and practicability is not strong.Although the sulfur elimination annotation method studies in China time is later, just began one's study, removed in recent years
The shortcomings that application of sulphur agent filling technique compensates for above-mentioned several method, for different choking portions under the premise of production is not influenced
Position carries out effective de-plugging, and the scope of application is wider, influences the advantages that little to system production operating parameter, so being still main sulphur removal
Blocking method, but sulfur elimination has certain corrosivity and toxicity, while with penetrating odor, has secondary pollution to environment, and existing
The sulfur elimination Sulfur capacity in stage is low, and the reaction time is long, and simple substance sulphur could effectively be dissolved by needing to contact for a long time, increase additive amount
With the addition period.
