Description
Technical field
The present invention relates to a kind of drilling fluid mud screening drying method for treating and drilling fluid mud screening plant, belong to petroleum drilling
Well liquid separation of solid and liquid, drilling cuttings drying and other treatment technical field.
Background technology
During petroleum drilling operation, drilling fluid is injected in pit shaft through between well drilling pipe column and pit shaft through well drilling pipe column hydrophthalmia
The annular space of formation is back to the ground circulatory system.Drilling fluid carries out drilling cuttings during being returned out from pit shaft, drilling cuttings is through shaking
Dynamic sieve, desander, centrifuge are separated, and the drilling cuttings being separated contains substantial amounts of drilling fluid, formation gas etc. and pollute
Composition.
At present, the drilling cuttings being separated generally all is emitted in the cesspool of well site, or solidified by concentration, or by its
Landfill.As environmental protection requirement is more and more stricter, the enhancing of corporate environment protective awareness, it is proposed that zero discharge of drill cuttings does not fall
The requirement on ground.Closed collection and transportation of cuttings are had begun to both at home and abroad to factory is focused on, and harmless treatment is carried out to drilling cuttings,
Propose the new ideas of situ of drilling well drill chip innocent processing in recent years simultaneously.But, processing cost is generally higher, it is difficult to push away
Extensively.
On the other hand, substantial amounts of liquid is contained in the drilling cuttings that the equipment such as vibratory sieve are separated due to passing through;And it is harmful
Gas and volatile organic content.Not only storage and freight volume are big, and easily occur because diafiltration comes out in storage and transportation process
Liquid landing and the pollution that causes of gas and volatile substances, and add the processing total amount focused on, cause
Make harmless treatment cost too high.
The content of the invention
It is an object of the invention to：A kind of drilling cuttings liquid content being effectively reduced after being separated is provided, while effectively removing
Drilling fluid mud screening plant and drilling fluid mud the screening drying and other treatment of pernicious gas and volatile organic content in drilling cuttings
Method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of drilling fluid mud sieves drying method for treating；It is characterized in that：It comprises the following steps：
1）, the drilling fluid mud that pit shaft is returned out is pumped into the material feeding box of drilling fluid mud screening plant out of collecting pit first
It is interior, and branched to by a point liquid bath for material feeding box on screen cloth, at the same control thickness of the drilling fluid mud on screen cloth 10-
30mm；
2）, control screen cloth rotating speed in 0.05 ~ 0.168m/s scopes, Vibration on Start-up motor, and control its vibration frequency 5000-
In the range of 7700Hz, so that vibrating motor drives screen cloth to vibrate by oscillating plate；
3）, oscillating plate is while drive screen cloth vibration, start vacuum plant, and control vacuum in 20KPa -60KPa scopes,
Acted on being passed to vacuum tank to screen cloth, so as to enter to the moisture in drilling fluid mud, pernicious gas and volatile materials
Row absorption, and desiccation is realized to drilling fluid mud；
4）, vacuum plant is by the moisture in drilling fluid mud, pernicious gas（Deng）And volatile materials
（Oil hydrocarbon compound, benzene homologues（Toluene, ethylbenzene, dimethylbenzene）After being adsorbed in vacuum plant, pernicious gas and volatile materials
It is separated from liquid phase, and burning processing is carried out through exhaust outlet discharge；The moisture that is adsorbed and part fine particle size are consolidated
Through entering subsequent work circulation in tube pump to the collecting pit that flows back；
5）, in the vacuum plant course of work, the drilling fluid mud on screen cloth after drying and other treatment（Filter cake）Before continuing with screen cloth
OK, when drilling fluid mud is moved at windward cutter position, upper air knife startup work during this, controls the work of upper air knife
Make angle in 20 ° -45 ° scopes, and control the wind speed of air knife in 510L/min -1650L/min scopes, to reduce drilling fluid mud
The speed of service of slurry, makes drilling fluid mud be rolled on screen cloth, so as to drilling fluid mud（Filter cake）Purging desiccation is carried out again
Processing；
6）, drilling fluid mud through drying and other treatment again（Filter cake）Continue to move ahead and drop in collecting union in disposable box with screen cloth
Middle processing, unloads drilling fluid mud（Filter cake）When screen cloth afterwards is run to leeward cutter position；Lower air knife startup work, with to sieve
The mud that is remained in net meshe carries out cleaning treatment, it is ensured that sieve mesh it is penetrating, during this, control the work of lower air knife
Angle controls the wind speed of air knife in 510L/min -1650L/min in 5 ° -10 ° scopes；
7）, the screen cloth after the cleaned processing of mesh be rotated further operation, screen cloth after cleaning treatment is run to material feeding box position
