Description
Technical field
The utility model belongs to oil-gas field surface engineering field, and in particular to a kind of three phases separator bottom
Line desanding device.
Background technology
In oil-gas field surface engineering, oil well produced liquid is generally the fluid-mixing of the compositions such as oil, gas and water, and fluid-mixing exists
Migrated in formation pore and pit shaft, inevitably carry the solid impurities such as silt particle.Horizontal oil, gas and water three phase separator are
The indispensable equipment of production fluid initial gross separation is carried out, the presence meeting wear valve sealing surface of solid impurity causes separator
The blocking of internals, and can be deposited in separator bottom, reduce the dischargeable capacity of water-oil separating, reduce separative efficiency, hinder
The normal operation of separator, increases production cost.
Existing horizontal separator axially would generally be set several bleed outlets in separator bottom, enter pedestrian
Work sediment outflow or waterpower sediment outflow.Artificial sediment outflow needs stopping production separator, and manpower enters separator interior, and cleaning sticks to tank bottom wall
The silt in face, and discharged by reserved sewage draining exit.This method causes production technology discontinuous, reduces production efficiency, operates
It is lengthy and tedious, add human intervention cost；Waterpower sediment outflow refers in separator running, opens separator bottom sand removing hole valve
Door, by the impact of separator lower floor separation water, silt particle is carried away from separator, this mode can only be attached by sand removing hole
Near impurity discharge, and be difficult that moreover the solid impurity sticked on tank skin is excluded to clean long-term solid deposition easily to make
Into the blocking of sand removing hole, in this case there is still a need for separator is stopped production, overhauled, and artificial sediment outflow is carried out.
The U of patent CN 202508938 disclose a set of online desanding device applied to three phase separator, using built-in point
Cloth jet nozzle, which washes away the solid impurity of tank bottom wall, to be pooled in tank bottom several sand removing holes, opens sand removing hole valve,
Carry out sediment outflow.Although this method can reach the purpose that separator interior solid impurity collects, jet nozzle is not accounted for
Disturbance can bring influence to the oil water separation process of expansion chamber, it is more likely that cause deposited solid impurity to roll to enter again
Enter profit settlement space, cause separating effect to be deteriorated.The U of patent CN 204663511 consider this problem, in jet nozzle
Top is provided with an orifice layer, it is to avoid the water of jet rolling and the oil mixing with water of settlement space, but this is also resulted in largely
Solid impurity is deposited on orifice layer, and is entered less than the desanding space below orifice layer, it is impossible to ensure deposition solid impurity
Effective removal.Above-mentioned two device also haves the shortcomings that common, a solid impurity head exactly collected by injection stream
Sand removing hole is first gathered, solid impurity density is larger, is deposited in sand removing hole, the time is more long, it is more fine and close, in Open valve
During sediment outflow, it is more likely that flowing is not smooth, results in blockage, causes sediment outflow to fail.
