Description
Technical field
The invention belongs to filtration and separation techniques field, be specifically related to a kind of filtration mud settling tank.
Background technology
At present, due to Exploitation Level of Oilfield well construction increasing number, in the horizontal well abrasive perforating stage, fracturing fluid and fracturing sand consumption very big, if the discarded fracturing fluid of direct discharge can cause the wasting of resources, also do not meet growth requirement that is 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 be separated with fracturing sand.
For this reason, the invention provides a kind of filtration mud settling tank, comprise tank body, feed tube, described tank interior is provided with liquid storage district and sand setting district, filtration wall is provided with between described liquid storage district and sand setting district, described feed tube is communicated with sand setting district, is provided with sand export bottom described sand setting district side, and described liquid storage district side is provided with leakage fluid dram.
Up big and down small funnel-form in described sand setting district.
The front in described sand setting district, rear and be the gradient slope of 40 ° ~ 50 ° close to filtering that wall side is equipped with the horizontal direction angle of cut.
Sand export is provided with bottom described liquid storage district.
The feed tube bracing frame for supporting feed tube is provided with in described tank body.
Described filtration wall forms by filling fine sand grain in screen pack.
Described fine sand grain 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: the requirement realizing fracturing fluid recycling, meet the construction demand of current green formation testing; Sand setting district adopts funnel-shaped structure, can realize direct cleaning, avoid artificial sand removal, and greatly reduces on-the-spot staff labor intensity and flow chart, in energy-saving and cost-reducing, environmental protection, essential safety, demonstrate higher economic and social benefit.
Be described in further details below in conjunction with accompanying drawing.

In figure: 1, tank body; 2, liquid storage district; 3, sand setting district; 4, feed tube; 5, wall is filtered; 6, gradient slope; 7, sand setting district sand export; 8, leakage fluid dram; 9, liquid storage district sand export; 10, pump interface; 11, union; 12, gate valve; 13, feed tube bracing frame.
Detailed description of the invention
In order to realize fracturing fluid recycling, present embodiments provide 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 liquid storage district 2 respectively, arrange between district of sand setting district 3, two and filter wall 5 and carry out filtrations isolation, filter wall 5 and be made up of filling 40 ~ 100 object fine sand grain 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 with the gradient slope 6 of filtering wall 5 and to be equipped with close to side 40 ° ~ 50 °, as shown in Figure 2; Feed tube 4 leads to sand setting district 3, is provided with sand export 7 bottom sand setting district 3 side, and liquid storage district 2 side is provided with leakage fluid dram 8, is provided with feed tube bracing frame 13 in tank body 1.
Before carrying out abrasive perforating operation, 2 cun of unions 11 of gate valve 12 and mud settling tank are put with high pressure line connecting well muzzle, pump interface 10 and other fluid reservoirs are connected 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.After starting abrasive perforating operation, load fluid, through feed tube 4, enters sand setting district 3, during this period, filtration sand through filtering wall 5 sinks to the bottom in sand setting district 3, liquid flows into liquid storage district 2, and during abrasive perforating, discharge capacity is larger, to overflow tank for avoiding liquid storage district 2, pump interface 10 can be opened, open explosion-proof positive displacement pump, the liquid in liquid storage district 2 is dredged other fluid reservoirs in time.After construction terminates, closing gate valve 12, after treating that the liquid in liquid storage district 2 all exports, opens sand export 7, cleans out remaining sand.
When load fluid face is higher than filtration wall 3 height, have small part fracturing sand to enter liquid storage district 2, the sand export 7 by liquid storage district 2 carries out sand removal.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
