Abstract
The invention discloses a saline water system of a marine drilling platform and a saline water purifying method based on the saline water system. The saline water system comprises a saline water pump, a mud mixing funnel and a saline water recovery pool, wherein a circulating system is formed by sequentially connecting the saline water pump, the mud mixing funnel and the saline water recovery pool in series, the mud mixing funnel is configured with a filter system which is in by-pass arrangement, and the filter system is respectively connected with an outlet of the saline water pump and an inlet of the saline water recovery pool through pipelines. The saline water system disclosed by the invention has the following advantages that (1) thick impurities in saline water of a water-based mud system can be successfully removed; (2) the purity of water-based mud can be greatly increased through a filter; (3) backflow mud enters into the saline water recovery pool and can pass through the filter after being subjected to lightering through the saline water pump, a refined filtering effect can be achieved by the filter at the moment, and the purity of saline water can be higher.
Description
Technical field
The present invention relates to a kind of marine drilling platform, especially a kind of brine system of marine drilling platform and the salt method for purifying water based on this brine system.
Background technology
On global oil drilling platform, requisite system is well system, and this wherein drilling fluid for platform, be the most important thing.Brine system (BRINE SYSTEM) is exactly for allocating drilling fluid, and in particular for water-base mud, water-base mud is with seawater, and the mud that fresh water and the allotment of chemical salt solution form, so now the quality of salt solution (BRINE) and purity just seem most important.On existing platform, in its brine system, by brine pump (BRINE PUMP), the salt solution of brine pit (BRINE TANK) the inside is lightered to mud sump (MUD PIT), be uniformly mixed.Among these systems, comprising the circulation of salt solution, existing most of offshore boring island can not add filter in the meantime, only can in mud return-flow system, add filter, such design also can cause oarse-grained material in brine system directly among existing system, to circulate, and cannot filter out, thereby can have influence on Na in water-base mud, Ca, Mg, the isoionic content of K is inhomogeneous, cannot reach the requirement of mud in our ideal.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of brine system of marine drilling platform is provided, the bypass filtration system increasing on the basis of the initial scheme that does not have to change and remove original system, and among this filtration system, also only need to increase a filter.
A brine system for marine drilling platform, comprises the brine pump, mud mixing hopper and the salt solution recovery pond that are connected into successively a circulating system, and described mud mixing hopper disposes the filtration system that bypass arranges; 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 comprises a strainer.
A salt method for purifying water for brine system based on above-mentioned marine drilling platform, the salt solution in brine pit pumps into strainer through brine pump to carry out after removal of impurities, in input salt solution recovery pond; Salt solution in salt solution recovery pond pumps into after mud mixing hopper by brine pump, mixes synthetic drilling fluid in mud sump, pumps into the unnecessary salt solution of mud mixing hopper in pipeline input salt solution recovery pond.
The backflow mud that salt solution mixing hopper exports salt solution recovery pond to pumps into strainer through brine pump and carries out essence filter operation.
Technical scheme based on above-mentioned, brine system of the present invention has following advantage: the thick impurity of the salt solution of (1) water-base mud system can be removed smoothly; (2) by this filter, the purity of water-base mud can be promoted greatly; (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; Strainer 4.
The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Below with reference to accompanying drawing, explain technical scheme of the present invention.
As shown in Figure 1, brine system of the present invention, comprises the brine pump, mud mixing hopper and the salt solution recovery pond that are connected into successively a circulating system, and described mud mixing hopper disposes the filtration system that bypass arranges; 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 comprises a strainer.
During use, by controlling the by-pass valve control on each branch road, realize different branch and carry out salt solution conveying, be specially:, the salt solution in brine pit pumps into strainer through brine pump to carry out after removal of impurities, in input salt solution recovery pond; Salt solution in salt solution recovery pond pumps into after mud mixing hopper by brine pump, mixes synthetic drilling fluid in mud sump, pumps into the unnecessary salt solution of mud mixing hopper in pipeline input salt solution recovery pond.The backflow mud that salt solution mixing hopper exports salt solution recovery pond to pumps into strainer through brine pump and carries out essence filter operation.
Therefore, the present invention has following advantage: the thick impurity of the salt solution of (1) water-base mud system can be removed smoothly; (2) by this filter, the purity of water-base mud can be promoted greatly; (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.
