Description

A kind of Solids control for drilling fluids blood circulation process
Technical field
The present invention relates to a kind of Solids control for drilling fluids blood circulation process, more particularly to a kind of oil and gas well drilling mistake The process of the Deal With Drilling Fluid produced in journey.
Background technology
Drilling fluid, is the fluid of the circulation used in drilling process, is the mixture of liquid, solid and chemical treatments. The circulation of drilling fluid is drilling fluid Jing after drilling pump pressurization obtains hydraulic pressure, is transported in drilling rod by high pressure pipe joint, faucet Chamber, along drilling rod inner chamber stream to underground, ejects from bit nozzle, ring of the landwaste that drill bit is crushed under a subterranean formation outside drilling rod Ground is taken back in shape space, and big drilling cuttings inside (mud) on ground, barite and other big solids will be returned by well head Grain is efficiently separated, and the drilling fluid (mud) for processing can be reused, so as to reduce the cost of drilling well, and favorably In environmental conservation.
Drilling practice shows, when in mud, solid phase particles reduce 1%, the life 7~10% of drill bit, drilling speed are improved More than 29%.In drilling process, excellent property of drilling fluid is to improve bit speed, reduces drilling cost, prevention down-hole thing Therefore, protection layer of oil gas production premise, and solidification control system for well drilling liguid be maintain property of drilling fluid guarantee.
Traditional abandoned well liquid processing method is emergency burial, specifically, for the situ of drilling well away from water head site, drilling well It is front to need to dig the mud ground of 2000 to 5000 sides in well site, plastic sheeting is laid, and rejected well drilling liquid is deposited with mud pit;Through The natural subsidence of mud pit, the slime water clarified above are used as circulation of drilling fluid;After drilling well is finished, by mud pit Addition cement and Calx, emergency burial.This traditional waste drilling fluids disposal method has the following disadvantages:1. through mud from So settle, the slime water clarified above is used as circulation of drilling fluid, because the viscosity and proportion of mud it is larger, solid phase therein Grain can only be slightly reduction, be continuing with this mud, necessarily have some landwaste and grit enters slush pump with mud, by again Secondary feeding shaft bottom, causes that slush pump is fragile and bit life is greatly shortened, and footage per bit is reduced, and drilling speed is reduced, substantial amounts of Landwaste and the grains of sand destroy the wall building property of mud, or even cause the accidents such as well slough, bit freezing;2. hole is cut the earth as discarded in well site , there is certain surface water pollution risk in drilling fluid storage pool, for example, heavy rain is run in work progress and other water sources collect Well site, rejected well drilling liquid may be leaked in neighbouring farmland, water body and topsoil, the ecological ring destroyed near well site Border;3. some areas have forbidden adopting emergency burial at present, require to clean out after completion, and cleaning work is time-consuming, high cost; 4. itself adopts the method high labor intensive digged pit on the spot, and efficiency is low.
It is many at present that traditional emergency burial mode is substituted by way of roping is focused on to treating stations, to reduce ecology The destruction of environment, generally in the form of large power drill well liquid holding vessel is placed on the spot, the drilling fluid that drilling platforms is produced is by defeated Pipeline is sent to flow into holding vessel, holding vessel is transported to treating stations using forklift or manual type after filling by holding vessel.It is main not enough: 1. holding vessel floor space is big;2. freight is high;3. high cost;4. efficiency is low;5. statistic analysis result shows, bores during drilling well The daily maintenance cost of well liquid about 90% is on solids control or the problem related with this, is increased, the expense of barite in drilling fluid With accounting for the 75% of the total Master Cost of drilling fluid, useful part slurry liquid can not be recycled, and cause drilling well operating cost high.
In recent years, solid controlling system has larger improvement, technological process from well-drilling liquid circulation pot to solid control equipment, technically Tend to be reasonable.The purification process of Solids control for drilling fluids equipment is about:Well head (drilling fluid for returning out) → drilling fluid vibrating sieve → true The drilling fluid of empty deaerator → drilling fluid desander → desilter → drilling fluid centrifuge → purification returns well head, main not enough: 1. screen of vibration screen for well drill liquid mesh selects more difficult and screen cloth easily to block up, and affects treatment effect;2. with drilling fluid desander, desilt Vibrosieve mesh supporting in device selects relatively difficult and screen cloth easily to block up, and affects treatment effect;3. due to drilling fluid centrifuge it Front processing apparatus Shortcomings, cause the mud in bulky grain footpath (more than 20 μm) to enter high speed centrifuge, affect drilling well centrifuge Separating effect, cause process after mud solid phase granule it is more, the service life of drill bit is short.
External solids control equipment performance is good, working stability, life-span length, has realized standardization, the series of device type Change and customizations.American petroleum Tools Co., ltd solid control system is made up of 4 vibrosieves and two exsiccators;4 are shaken Dynamic sieve and an exsiccator are connected in parallel, and the drilling fluid returned out in well is diverted to 4 vibrosieves and one by drilling fluid allotter Platform exsiccator is processed, and the solid phase particles that they isolate are processed by another exsiccator again, granule is further taken off Water;The liquids recovery of abjection, dry granule are drained off, its main deficiency:1. vibrosieve and exsiccator screen cloth mesh select tired Difficulty, and screen cloth easily blocks up;2. imported product is expensive, and accessory high cost, cycle are long.
The utility model patent of Patent No. 201420016318.4《A kind of waste drilling fluids disposal system and its collection dress Put》, it is primarily present deficiency:Useful part drilling fluid can not be recycled, and cause drilling well operating cost high.
The utility model patent of Patent No. 201320881564.1《Waste liquid Deal With Drilling Fluid device》, it is primarily present not Foot:Jing after taking off steady separative element, no concentration process is directly entered filter press to rejected well drilling liquid, due to feed thickness it is low, Cause filter press inefficiency.
As the development of oil exploration industry, drilling depth are continuously increased, drilling strata is increasingly complicated, deep-well, ultradeep well, The exceptional wells such as horizontal well, underbalance well are more and more, and solidification control system for well drilling liguid is put forward higher requirement.
