Abstract
The invention belongs to the technical field of filtering separation and particularly relates to a filtering sand settling tank, which comprises a tank body and a liquid inlet pipe, wherein a liquid storage area and a sand settling area are arranged in the tank body; a filtering wall is arranged between the liquid storage area and the sand settling area; the water inlet pipe is communicatedwith the sand settling area; a sand outlet is formed in the bottom of the side edge of the sand settling area; a liquid drainage opening is formed in the side edge of the liquid storage area. The filtering sand settling tank provided by the invention has the benefits as follows: the requirement of recycling fracturing fluid is met, the construction requirements of green testing for oil at present are met, the sand settling area adopts a funnel-shaped structure, so that the sand settling area can be cleaned directly, manual sand removal is avoided, labor strength of site staff and operation process are reduced greatly, and the filtering sand settling tank has higher economic and social benefits on the aspects of energy conservation and consumption reduction, environmental protection, and intrinsic safety.
Description
Technical field
The invention belongs to filtration and separation techniques field, be specifically related to a kind of mud settling tank that filters.
Background technology
At present, because Exploitation Level of Oilfield well construction quantity increases severely, in the horizontal well abrasive perforating stage, fracturing fluid and fracturing sand consumption are very big, if the discarded fracturing fluid of direct discharge can cause the wasting of resources, also do not meet the growth requirement energy-saving and cost-reducing, environmental protection of constructing at present.
Summary of the invention
The object of the invention is to overcome the problem that fracturing fluid can not effectively separate with fracturing sand.
For this reason, the invention provides a kind of mud settling tank that filters, comprise tank body, feed tube, described tank interior is provided with liquid storage district and sand setting district, between described liquid storage district and sand setting district, be provided with filtration wall, described feed tube is communicated with sand setting district, and side bottom in described sand setting district is provided with sand export, and described liquid storage district side is provided with leakage fluid dram.
In described sand setting district, it is up big and down small funnel-form.
It is the gradient slope of 40 ° ~ 50 ° that the front in described sand setting district, rear and approaching filters that wall one side is equipped with the horizontal direction angle of cut.
Bottom, described liquid storage district is provided with sand export.
In described tank body, be provided with the feed tube bracing frame for supporting feed tube.
Described filtration wall forms by filling fine sand particle in screen pack.
Described fine sand particle is 40 ~ 100 orders.
Described filtration wall thickness is 5 ~ 15cm, and described filtration wall height is lower than the height of tank body.
Described liquid storage district is also provided with pump interface.
The invention has the beneficial effects as follows: realize the requirement of fracturing fluid recycling, meet the construction demand of current green formation testing; Sand setting district adopts funnel-shaped structure, can realize direct cleaning, has avoided artificial sand removal, and has greatly reduced on-the-spot staff labor intensity and flow chart, aspect energy-saving and cost-reducing, environmental protection, essential safety, is demonstrating higher economic and social benefit.
Be described in further details below in conjunction with accompanying drawing.

Detailed description of the invention
In order to realize fracturing fluid recycling, the present embodiment provides a kind of filtration mud settling tank as shown in Figure 1, comprise tank body 1, feed tube 4, this filtration mud settling tank is divided into 2 regions, be respectively filtration wall 5 to be set between liquid storage district 2,3rd, two district of sand setting district filter isolation, filter wall 5 and form by filling 40 ~ 100 object fine sand particles in screen pack, filtering wall 5 thickness is 5 ~ 15cm, and height is lower than the height of tank body 1; Sand setting district 3 is up big and down small funnel-form, the front in sand setting district 3, rear and approach the gradient slope 6 that a side is equipped with 40 ° ~ 50 ° with filtering wall 5, as shown in Figure 2; Feed tube 4 leads to sand setting district 3, and 3 side bottoms, sand setting district are provided with sand export 7, and liquid storage district 2 sides are provided with leakage fluid dram 8, are provided with feed tube bracing frame 13 in tank body 1.
Carrying out before abrasive perforating operation, put 2 cun of unions 11 of gate valve 12 and mud settling tank with high pressure line connecting well muzzle, connect pump interface 10 and other fluid reservoirs with 4 cun of feed tubes 4, to reduce the erosion of load fluid to pipeline, then open gate valve 12, close leakage fluid dram 8, pump interface 10, sand export 9.Start after abrasive perforating operation, load fluid, through feed tube 4, enters sand setting district 3, during this period, sink to the bottom in sand setting district 3 through filtering the filtration sand of wall 5, liquid flows into liquid storage district 2, and during abrasive perforating, discharge capacity is larger, for avoiding the excessive tank in liquid storage district 2, can open pump interface 10, open explosion-proof positive displacement pump, the liquid in liquid storage district 2 is dredged to other fluid reservoirs in time.After construction finishes, closing gate valve 12, after treating the whole output of liquid in liquid storage district 2, opens sand export 7, cleans out remaining sand.
When load fluid face is when filtering wall 3 height, there is small part fracturing sand to enter liquid storage district 2, can carry out sand removal by the sand export in liquid storage district 27.
More than exemplifying is only to illustrate of the present invention, does not form the restriction to protection scope of the present invention, within the every and same or analogous design of the present invention all belongs to protection scope of the present invention.
