Fig. 1 shows the structural representation of petroleum drilling fluid solidifying and controlling device according to an embodiment of the invention.
Wherein, the corresponding name of the Reference numeral in accompanying drawing is called:
101-vibrosieve, 102-drilling fluid pipe, 103-pipeline, 104-mid-speed centrifuge, 105-supercentrifuge, 106-pump, 107-reserving chamber, the top of 108-reserving chamber, the bottom of 109-reserving chamber.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Fig. 1 shows the structural representation of petroleum drilling fluid solidifying and controlling device according to an embodiment of the invention.With reference to a kind of petroleum drilling fluid solidifying and controlling device shown in figure 1, involving vibrations sieve 101, described vibrosieve 101 is 4, the entrance of described 4 vibrosieves 101 is connected with drilling fluid pipe 102 respectively, the outlet of described 4 vibrosieves 101 is connected with mid-speed centrifuge 104 by pipeline 103 again, described mid-speed centrifuge 104 is connected with supercentrifuge 105 again, described supercentrifuge 105 is connected with the top 108 of reserving chamber 107 by pump 106 again, and the bottom 109 of described reserving chamber 107 is connected with removing drilling well mouth pipeline 110; The rotating speed of described mid-speed centrifuge 104 is 10000～15000r/rain, and the rotating speed of described supercentrifuge 105 is 20000～30000r/rain.
4 vibrosieves 101 are arranged on same vertical direction, and the vibrosieve being positioned at is bottom connected with desanding desilter all-in-one.
The sieve number of described 4 vibrosieves 101 is more than 120 orders.
Described pump 106 is peripheral pump.
In sum, petroleum drilling fluid solidifying and controlling device of the present invention adopts secondary solid controlling: i.e. vibrosieve 101+ centrifuge, be equipped with four high performance vibrosieves 101, and on last vibrosieve 101, join desanding desilter all-in-one, next join a 40-50mP
3the large discharge capacity centrifuge 104 of middling speed and a 40-50mP of P/h
3p/h supercentrifuge 105.The onset point of this scheme is under normal circumstances, can start three or four vibrosieves 101 simultaneously, a vibrosieve 101 for subsequent use.More than ensureing that under normal circumstances vibrosieve 101 sieve numbers reach 120 orders, the one that desanding desilter all-in-one uses when just conduct runs into clay stratum is for subsequent use, normally no.In lightweight mud, centrifuge is mainly used in except solid phase, and by principle processing in turn, the workflow of centrifuge is the enter slurry of vibrosieve mud after treatment as the large discharge capacity centrifuge of middling speed, and mid-speed centrifuge 104 treating capacities are 40-50mP
3p/h, burble point 10-20 μ m; It can be got rid of oarse-grained harmful solid phase to go from underflow opening, and overflow after desanding is got back in tank.In weighted mud, when mud viscosity very large, and density is moderate or time on the low side, ultra-fine solid phase and colloid solid concentration of this explanation mud are too high, and this granularity is 2 μ m left and right, therefore, need to reclaim the underflow of mid-speed centrifuge 104, its underflow major part is barite and Iron Ore Powder, is conducive to ensure density, and flooding point major part is ultra-fine solid phase and colloid solid phase, must process.Can set it as the slurry that spouts of supercentrifuge 105, the burble point of supercentrifuge 105 is 1-5 μ m.Therefore, can be by its colloid solid phase after supercentrifuge 105 work, the underflow of superfine solid phase is discharged to outside tank, and it is with slurry that the synthetic premium mud lightweight that contains water and medicine is overflowed back to dilution, mud system just can keep mud density and viscosity greatly to reduce, make centrifuge play the effect of secrecy viscosity reduction degree, in significantly saving mud cost, ensure the control to weighted mud system performance, can also greatly reduce the energy consumption of solid controlling process.
In this manual, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment, identical similar part cross-references between each embodiment.
Although with reference to multiple explanatory embodiment of the present invention, invention has been described here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiments, within these amendments and embodiment will drop on the disclosed principle scope and spirit of the application.
