Abstract
The invention provides a three-in-one sand and mud removing device. The three-in-one sand and mud removing device comprises an inlet gate, a first-level sand remover, a second-level sand remover, a third-level mud remover and an outlet gate, wherein the inlet gate is fixedly connected and communicated with the first-level sand remover, the second-level sand remover, the third-level mud remover and the outlet gate in sequence. The first-level sand remover comprises a sand screen, a sand storage pool and a sand removing gate; the sand screen is arranged at an outlet of connection between the sand storage pool and the second-level sand remover; and the sand removing gate is arranged at the bottom of the sand storage pool. The three-in-one sand and mud removing device has the following beneficial effects: the sand and mud removing efficiency is improved by 15% compared with that of the prior art, and the operation is more convenient; and the three-in-one sand and mud removing device has the advantages of simple structure, convenience for maintenance, low processing cost, etc.
Description
Technical field
The present invention relates to field of petroleum exploitation, especially relate to a kind of three-in-one desanding desludging device.
Background technology
In existing technology, in oil, gas drilling process, from well head counter go out drilling fluid contain a large amount of drilling cuttings and silt, solid impurity wherein must be removed, just can return down-hole use.This work is called oil-water well circulation sand washing operation, and solid particle and little clay particles are separated by it from drilling fluid.Conventional treatment method is: first after vibrosieve first order purified treatment, then is separated for three times by desander, desilter, centrifuge, could obtain premium drilling fluid of good performance.But there is the technical problems such as separation progression is many, complex structure, cost are high, resettlement is inconvenient in this method.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of desanding desludging device, is especially applicable to a kind of three-in-one desanding desludging device.
For solving the problems of the technologies described above, the technical solution used in the present invention comprises entrance gate, one-level desander, secondary desander, three grades of desilters and goes out port strobe, and entrance gate is successively with one-level desander, secondary desander, three grades of desilters with to go out port strobe affixed and be communicated with.
Further, described one-level desander comprises sieve sand net, sand storage tank and sediment outflow gate, and sieve sand net is arranged on sand storage tank and is communicated with secondary desander and exports, and sediment outflow gate locating is bottom sand storage tank.
Further, described secondary desander comprises secondary inlet, vortex sand removing device, sand storage tank and sediment outflow gate, secondary inlet is arranged on the upper surface of secondary desander, vortex sand removing device is vertically fixed on the upper surface of secondary desander, secondary desander lower end arranges sand storage tank, arranges sediment outflow gate bottom secondary desander.
Further, described three grades of desilters comprise three grades of entrances, tank body, conical sand bin, sand strip, three grades of outlets, and three grades of entrances connect tank body top, and three grades of outlets are fixed in tank body central part, at the sand strip of the affixed vertical ground of tank inner surface, the affixed conical sand bin of tank body lower part.
Further, described tank body is cylindrical tank.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, and desanding, desilt efficiency improve 15% than prior art, more convenient to operate; There is structure simple, easy to maintenance, the advantages such as processing cost is low.
