Abstract
The invention discloses the brine system of a kind of marine drilling platform and salt method for purifying water based on this brine system, described brine system includes being sequentially connected in series into the brine pump of a circulatory system, mud mixing hopper and salt solution recovery pond, and described mud mixing hopper is configured with the filtration system that bypass is arranged；This filtration system is connected with the import of salt solution delivery side of pump and salt solution recovery pond by pipeline respectively.Therefore, the invention have the advantages that the thick impurity of the salt solution of (1) water-base mud system can remove smoothly；(2) purity of water-base mud can be greatly promoted by this filter；(3), during backflow mud enters in salt solution recovery pond, through brine pump transportation by lighter by filter, now this filter can reach the effect of essence filter.Make salt solution purity higher.
Description
Technical field
The present invention relates to a kind of marine drilling platform, the brine system of a kind of marine drilling platform and salt method for purifying water based on this brine system.
Background technology
On global oil drilling platform, requisite system is well system, and drilling fluid is the most important thing for platform among these.Brine system (BRINE SYSTEM) is just used to allocate drilling fluid, and in particular for water-base mud, water-base mud is with seawater, fresh water and the mud of chemistry salt solution allotment, so now the quality of salt solution (BRINE) just seems most important with purity.On existing platform, the salt solution of brine pit (BRINE TANK) the inside is lightered mud sump (MUD PIT) by brine pump (BRINE PUMP) by its brine system, is stirred mixing.Comprise the circulation of salt solution among these systems, existing major part drilling platforms will not add filter in the meantime, only can add filter in mud return-flow system, such design also results in oarse-grained material in brine system and is directly circulated among existing system, and cannot filter out, thus influences whether Na in water-base mud, Ca, the isoionic content of Mg, K is uneven, it is impossible to reach the requirement of mud in our ideal.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the brine system of a kind of marine drilling platform, at the bypass filtration system not changed and on the basis of the initial scheme of removal original system, face increases, and also need only among this filtration system increase a filter.
The brine system of a kind of marine drilling platform, including being sequentially connected in series into the brine pump of a circulatory system, mud mixing hopper and salt solution recovery pond, described mud mixing hopper is configured with the filtration system that bypass is arranged；This filtration system is connected with the import of salt solution delivery side of pump and salt solution recovery pond by pipeline respectively.
Described filtration system includes a filter.
The salt method for purifying water of a kind of brine system based on above-mentioned marine drilling platform, the salt solution in brine pit pumps into after filter carries out removal of impurities through brine pump, in input salt solution recovery pond；After salt solution in salt solution recovery pond pumps into mud mixing hopper by brine pump, mud sump is mixed synthetic drilling fluid, pump into the unnecessary salt solution of mud mixing hopper in pipeline input salt solution recovery pond.
Salt solution mixing hopper output to salt solution recovery pond backflow mud through brine pump pump into filter carry out essence filter operation.
Based on above-mentioned technical scheme, brine system of the present invention has several advantages that the thick impurity of the salt solution of (1) water-base mud system can remove smoothly；(2) purity of water-base mud can be greatly promoted by this filter；(3) backflow mud enters in salt solution recovery pond in (RESERVE BRINE TANK), and through BRINE PUMP transportation by lighter by BRINE FILTER, now this filter can reach the effect of essence filter.Make salt solution purity higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of brine system of the present invention；
In figure: brine pump 1；Salt solution mixing hopper 2；Salt solution recovery pond 3；Filter 4.
Detailed description of the invention
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation；Technical scheme is explained below with reference to accompanying drawing.
As it is shown in figure 1, brine system of the present invention, including being sequentially connected in series into the brine pump of a circulatory system, mud mixing hopper and salt solution recovery pond, described mud mixing hopper is configured with the filtration system that bypass is arranged；This filtration system is connected with the import of salt solution delivery side of pump and salt solution recovery pond by pipeline respectively.Filtration system of the present invention only includes a filter.
During use, by controlling the control valve on each branch road, it is achieved different branch carries out salt solution conveying, particularly as follows:, the salt solution in brine pit pumps into after filter carries out removal of impurities through brine pump, in input salt solution recovery pond；After salt solution in salt solution recovery pond pumps into mud mixing hopper by brine pump, mud sump is mixed synthetic drilling fluid, pump into the unnecessary salt solution of mud mixing hopper in pipeline input salt solution recovery pond.Salt solution mixing hopper output to salt solution recovery pond backflow mud through brine pump pump into filter carry out essence filter operation.
Therefore, the method have the advantages that the thick impurity of the salt solution of (1) water-base mud system can remove smoothly；(2) purity of water-base mud can be greatly promoted by this filter；(3) backflow mud enters in salt solution recovery pond in (RESERVE BRINE TANK), and through BRINE PUMP transportation by lighter by BRINE FILTER, now this filter can reach the effect of essence filter.Make salt solution purity higher.
