At 10 center of rig substructure in well head tank；Drilling fluid tank A1, drilling fluid tank B13 are located at 10 outside of rig substructure；Drilling fluid tank
A1 connects drilling fluid tank B13 by 2 vertical pumps 5；The drilling fluid tank B13 is isolated into 4 storehouses: being followed successively by sand setting storehouse 14, removes
Sand warehouse 15, centrifuging chamber 16 and reserving chamber 17；Described 2 vertical pumps 5 of drilling fluid tank B13 connection, blender 4, on drilling fluid tank B13
Portion there also is provided 6,25 egress line of vertical pump connection 6,2 vertical pumps 5 of desanding desilter of desanding desilter and desanding desilter 6
Lower part is corresponding to remove sand warehouse 15, and the opposite pollution discharge pond 3 of sand plate 18, desanding desilter 6 are drawn in the connection of 6 outside sand removing hole of desanding desilter
Lower part slurry outlet opposite direction removes sand warehouse 15；Reserving chamber, centrifuging chamber are provided with blender 4；The purpose of sand setting storehouse is arranged is to realize
The natural subsidence of drilling fluid solid granule in this storehouse；Except sand warehouse top is equipped with vertical pump and desanding desilter, its work
With being to pump the drilling fluid in this storehouse using vertical pump to give desanding desilter, by desanding desilter, to drilling fluid carry out into
The processing of one step removes wherein smaller particle, the wire screen mesh number of vibrating screen and is less than the wire screen mesh number of desanding desilter, so
Desanding desilter can remove the little particle that vibrating screen is not removed；Reserving chamber is the deposit structure an of drilling fluid, is used for
There are connecting tube and valve in the storage of spare drilling fluid, its underpart, can be with the connection of centrifuging chamber and drilling fluid tank B13 and drilling pump
It mouthful communicates, realizes and flow between the storehouse of drilling fluid；Centrifuging chamber be under normal circumstances, directly be drilling pump feed flow storehouse, by tank
Connecting tube be directly connected with except sand warehouse；The wire screen mesh number of vibrating screen is 60 mesh, and the wire screen mesh number of desanding desilter is 120 mesh.
The middle-size and small-size drill drilling liquid closed-cycle system, drilling fluid tank A1 are low level tank, arrange two vibrating screens above,
Drilling fluid scheduling is carried out by vertical sand pump, realizes that drilling fluid smoothly sucks vibrating screen, completes drilling fluid tank A1 sieving drilling fluid
Processing task also arranges 2 vertical pumps, and the drilling fluid after screening is promoted and is pumped into drilling fluid tank B13；Drilling fluid tank B13 is height
Position tank, be isolated into 4 storehouses: sand warehouse and centrifuging chamber, are removed at reserving chamber in sand setting storehouse.Drilling fluid tank B13 arranges desanding desilter 6,2
Vertical sand pump, 3 blenders mainly undertake drilling fluid desanding-and desilt processing and storage treated drilling fluid task, while real
The function that existing drilling fluid aggravates.
The middle-size and small-size drill drilling liquid closed-cycle system use process are as follows: drilling fluid closed-cycle system operational process point
Two stages.First stage is out the stage, (i.e. there are no the stages of simple to install well head), before pedestal is installed in place, needs
A dell being closely sized to well head tank is excavated at well head in advance, for placing well head tank.Well head tank after the installation is completed,
The installation exercise of pedestal is carried out again.After all devices are installed in place, carry out one and open operation, the vertical pump being arranged in well head tank at this time
By lower diversion pipe, the drilling fluid that well head is returned out is transported to vibrating screen.Vibrating screen by the sieving drilling fluid of conveying at two parts,
A part of solid bulky grain (landwaste and silt) exports from Vibration Screen, is admitted to waste liquid pool by drawing sand plate, another part contains
There is the inexpungible short grained drilling fluid of vibration sieve plate, drained in drilling fluid tank A1 from sieve plate, vibration lower part of screen is not appointed
What equipment, therefore the little particle contained in vibration lower part of screen, drilling fluid can be with natural subsidence.The surface layout of drilling fluid tank A1
Drilling fluid in tank is transported to sand setting storehouse in drilling fluid tank B13, realizes the connection of two tanks by 2 vertical pumps.Drilling fluid tank
B13 is divided into four storehouses altogether, and sand warehouse, centrifuging chamber, reserving chamber are removed in desilting storehouse.Desilting storehouse with except sand warehouse be equipped with lower than tank it is high every
Plate after desilting storehouse is bought securities with all one's capital, flows into desanding storehouse from partition top.In sand setting storehouse, the particle of drilling fluid sinks naturally under the effect of gravity
Drop.In the tank face of drilling fluid tank B13, except two vertical pumps and a desanding desilter are mounted at the top of sand warehouse, two are vertical
Pump is desanding desilter feed flow.Drilling fluid into desanding desilter is divided into two parts outflow, and a part of small solid phase particles are removed
The wire screen of sand desilter, which screens out, to be come, and is directly entered by drawing sand plate and is reached waste liquid pool, another liquid is directly leaked by wire screen
To except in sand warehouse.Except sand warehouse and centrifuging chamber partition are completely separated.Connection is equipped in the bottom except sand warehouse, centrifuging chamber, reserving chamber
Pipe and gate, connecting tube are directly connected to the inlet of drilling pump, under normal circumstances, only except sand warehouse is connected with centrifuging chamber
(why centrifuging chamber is centrifuging chamber, is because in the construction of special well type, it is desirable that install centrifuge on the top of centrifuging chamber) is
Drilling pump feed flow, there are the complex situations such as leakage in underground, when drilling fluid being caused to reduce, by open gate by reserving chamber also with brill
Well pump connection, compensates the missing amount of drilling fluid.
Two when opening construction, is mounted with that simple upper section well head, simple upper section well head are provided with water outlet in well head, is discharged
The position of mouth is higher than vibrating screen plane, and the drilling fluid returned out in pit shaft is directly entered vibration by upper diversion pipe from water outlet
Sieve does not need the service hoisting effect of well head vertical pump.Remaining process is opened identical with one.
