Description
Technical field
The present invention relates to a kind of Solids control for drilling fluids circulating system process, the process of the Deal With Drilling Fluid particularly produced in a kind of oil and gas well drilling process.
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; that drilling fluid is after borehole pump pressurization obtains hydraulic pressure; drilling rod inner chamber is transported to by high pressure pipe joint, water tap; underground is flow to along drilling rod inner chamber; eject from bit nozzle; the landwaste that drill bit is broken under a subterranean formation takes back ground along the annular space outside drilling rod; large drilling cuttings, barite and other the large solid particle of (mud) the inside being returned to ground by well head are effectively separated; the drilling fluid (mud) processed can be reused; thus reduce the cost of drilling well, and be conducive to environmental protection.
Drilling practice shows, when in mud, solid phase particles reduces 1%, the life 7 ~ 10% of drill bit, drilling speed improves more than 29%.In drilling process, excellent property of drilling fluid improves bit speed, reduce the prerequisite of drilling cost, prevention down-hole accident, protection layer of oil gas production, and solidification control system for well drilling liguid is the guarantee maintaining property of drilling fluid.
Traditional abandoned well liquid processing method is emergency burial, particularly, for the situ of drilling well away from water head site, needs the mud ground digging 2000 to 5000 sides in well site, lay plastic sheeting, and deposit rejected well drilling liquid with mud pit before drilling well; Through the natural subsidence of mud pit, the slime water clarified above uses as circulation of drilling fluid; After drilling well, by adding cement and lime in mud pit, emergency burial.This traditional waste drilling fluids disposal method has the following disadvantages: 1. through the natural subsidence of mud, the slime water clarified above uses as circulation of drilling fluid, because of the viscosity of mud and proportion larger, solid phase particles wherein can only minimizing slightly, continue to use this mud, some landwaste must be had and grit enters slush pump with mud, again sent into shaft bottom, cause the shortening greatly of the fragile and bit life of slush pump, footage per bit reduces, drilling speed reduces, a large amount of landwaste and the grains of sand destroy the wall building property of mud, even cause well slough, the accidents such as bit freezing, 2. hole is cut the earth in well site as rejected well drilling liquid storage pool, there is certain surface water pollution risk, in work progress, such as run into heavy rain collect well site with other water sources, rejected well drilling liquid may leak in contiguous farmland, water body and topsoil, destroys the ecological environment near well site, 3. some areas have forbidden adopting emergency burial at present, and require after completion to clean out, cleaning work is time-consuming, and cost is high, 4. the employing method labour intensity of digging pit on the spot own is large, and efficiency is low.
Many modes focused on by roping to treating stations substitute traditional emergency burial mode at present, to reduce the destruction of ecological environment, generally adopt the form of placing machinery liquid holding vessel on the spot, the drilling fluid that offshore boring island produces flows into holding vessel by conveyance conduit, and holding vessel fills rear use forklift or holding vessel is transported to treating stations by manual type.Main deficiency: 1. holding vessel floor space is large; 2. freight is high; 3. cost is high; 4. efficiency is low; 5. statistic analysis result shows, during drilling well, drilling fluid maintenance cost every day about 90% is at solids control or with in this relevant problem, increase the weight of in drilling fluid, bar expense accounts for 75% of the total Master Cost of drilling fluid, useful part slurry liquid can not recycle, and causes drilling well running cost high.
In recent years, solid controlling system is from well-drilling liquid circulation pot to solid control equipment, and technically had larger improvement, technological process tends to be reasonable.The purification process of Solids control for drilling fluids equipment is roughly: the drilling fluid of well head (drilling fluid returned out) → drilling fluid vibrating sieve → vacuum degasser → drilling fluid desander → desilter → drilling fluid centrifuge → purification returns well head, main deficiency: 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 supporting vibrosieve mesh selection and comparison difficulty in drilling fluid desander, desilter and screen cloth easily block up, affect treatment effect; 3. due to processing apparatus Shortcomings before drilling fluid centrifuge, the mud in bulky grain footpath (being greater than 20 μm) is caused to enter supercentrifuge, affect the separating effect of drilling well centrifuge, cause the mud solid phase particle after processing more, the application life of drill bit is short.
External solids control equipment performance is good, working stability, life-span are long, has realized the standardization of device type, seriation and customizations.American petroleum Tools Co., ltd solid control system is made up of 4 vibrosieves and two dryers; 4 vibrosieves and a dryer are connected in parallel, the drilling fluid returned out in well is diverted to 4 vibrosieves by drilling fluid distributor and a dryer processes, their isolated solid phase particles are processed by another dryer again, and particle is dewatered further; The liquids recovery of deviating from, dry particle is drained, and it is mainly not enough: 1. vibrosieve and dryer screen cloth mesh select difficulty, and screen cloth easily blocks up; 2. imported product is expensive, and accessory cost is high, and the cycle is long.
The patent No. is the utility model patent " a kind of waste drilling fluids disposal system and gathering-device thereof " of 201420016318.4, and main Shortcomings: useful part drilling fluid can not recycle, causes drilling well running cost high.
The patent No. is the utility model patent " waste liquid Deal With Drilling Fluid device " of 201320881564.1, main Shortcomings: rejected well drilling liquid, after de-steady separative element, does not have concentration process, directly enters plate and frame filter press, because feed thickness is low, cause plate and frame filter press inefficiency.
Along with the development of oil exploration industry, drilling depth constantly increases, and drilling strata is day by day complicated, and the exceptional wells such as deep-well, ultradeep well, horizontal well, underbalance well get more and more, and have higher requirement to solidification control system for well drilling liguid.
