Description

Oil drilling equipment and solid controlling environment protection circulation of drilling fluid treatment system thereof
Technical field
The utility model relates to drilling assistance technical field, particularly a kind of solid controlling environment protection circulation of drilling fluid treatment system for oil drilling equipment.The utility model also relates to a kind of oil drilling equipment comprising above-mentioned solid controlling environment protection circulation of drilling fluid treatment system.
Background technology
Drilling fluid is a kind of circulation of fluid for drilling well, is in drilling process, the cyclic flusher medium used in hole.Drilling fluid has carry and suspend landwaste, equilibrium strata pressure, cooling and lubricating drill bit and drilling tool in pit shaft, the protection borehole wall and oil-gas Layer and improves the functions such as bit speed, has very important effect in drilling process.
Waste liquid of drilling (mud) is a kind of heterogeneous stable colloidal suspension system, containing materials such as plurality of inorganic salt, organic agent, polymer, surfactants, wherein heavy-metal pollution soil, the water body of contained oils, salt, drilling fluid additive and some solubilities, affect animal and plant growth, harm humans is healthy, needs to process waste liquid of drilling in time.Conventional drilling-fluid circulation system only relies on the vibrosieve of the offshore boring island circulating system self, and desander, the drilling fluid circulating out from well processes by desilter and centrifuge.Particularly, from the drilling fluid with a large amount of landwaste (harmful solid phase) that well head returns out, flow to the entrance of first order cleaning equipment-vibrosieve under gravity by the overhead drilling fluid canal in length and breadth (with certain slope) of well head, larger harmful solid phase particles sifts out and drains by the screening through vibrosieve.When drilling fluid occurs that gas soaks, in the mud settling tank of the drill fluid purification tank be purified by vibrosieve, utilize the swabbing action of deaerator vacuum pump, negative pressure is caused in vacuum tank, drilling fluid enters in deaerator under atmospheric pressure and is separated, the gas that sub-argument goes out is discharged into crown emptying, and the drilling fluid after degasification is arranged in drilling fluid No. 2 tanks under the driving of evacuation chamber rotor.When drilling fluid is not containing gas, deaerator can be used as powerful agitator, keep the drilling fluid in purification pot not precipitate.The drilling fluid be purified by vibrosieve enters in the mud settling tank of drilling fluid tank, desanding sand pump is utilized to enter in the desander of second level cleaning equipment-associating cleaner by drilling fluid pressurization, utilize eddy flow principle to be again separated, will harmful solids removal of mid point d50 >=70 be separated.Drilling fluid after desanding is arranged in drilling fluid No. 3 tanks through the overflow line of desander.According to the general requirement of drilling fluid cleaning system, the treating capacity of desander reaches more than 125% of normal circulation of drilling fluid amount, makes the drilling fluid in purification pot can obtain repeatedly purifying fully, reduces the sand content of drilling fluid.The drilling fluid be purified by desander is utilized except drilling fluid pressurization enters in the desilter of third level cleaning equipment-associating cleaner by sand pump, utilizes eddy flow principle to be again separated, and will be separated harmful solids removal of more than mid point d50=36um.Drilling fluid after desilt is arranged in drilling fluid No. 4 tanks through the overflow line of desilter.Containing certain drilling fluid in the underflow that desander and desilter are discharged, again sieve in the two underflow enters associating cleaner vibrosieve after joining, drilling fluid reclamation enters drilling fluid tank, the discharge of sand mud.Still containing a large amount of harmful solid phases in the drilling fluid of three grades of purifications, when drilling fluid be non-increase the weight of state time, utilize two desk centrifuge parallel connections to use, the harmful solid phase being greater than 5um in drilling fluid removed, the drilling fluid after process is arranged in the 5th storehouse of drill fluid purification tank.
