Description
Technical field
The present invention relates to CO2Dry method fracturing technique field, closed more particularly to a kind of dry method pressure break continuously add sand to mix
Close tank.
Background technology
Oil field carries out CO2During dry method pressing crack construction operation, it is necessary to by sand grains continuously with liquid CO2Mixing is together noted
Enter underground.Liquid CO2Usually at -20 DEG C or so, as the rise of temperature has gaseous state CO2Produce, if liquid CO2In contain
There is gaseous state CO2Fracturing unit truck just cisco unity malfunction.
Existing two kinds of plus sand Processes and apparatus, one kind are that sand grains is loaded into a tank container, close backward tank
Inside it is filled with gaseous state CO2Sand grains is cooled down, sand grains is mixed into liquid CO2Shi Wendu will not be raised, and make to keep in tank container
Certain pressure, we are referred to as the sand feeding equipment of hermetic type.Because the equipment is will just to open to make work after the built-in sand filling of tank,
Sand, which is finished, in tank just will be stopped, it is impossible to realize continuously plus sand, be additionally, since and do not stir, sand grains is in pipeline and liquid
CO2Freely mix, mixed effect is poor, sand feeding amount seldom (sand/liquid CO2Ratio it is general value below 5%).Another kind is by sand
In grain input agitator, substantial amounts of tackifier are added in order to increase its mobility, are injected into after stirring with pressure break pump truck
Well head and liquid CO2Mixing.This sand blender is due to being open type, and without the presence of impressed pressure, we are called normal pressure
Type sand feeding equipment, sand grains and tackifier can continually add agitator and ceaselessly export.But because having used substantial amounts of thickening
Agent, so cost is significantly increased, while pollution is also caused to stratum.
The content of the invention
The technical problem to be solved in the present invention is to provide simple in construction, easy to operate, the liquid CO of one kind2It is equal with mortar mixing
It is even, liquid CO2Band sand amount is big, while reduces tackifier dosage, and the closed of dry method pressure break for avoiding formation contaminant continuously adds
Sand blending tank.
Dry method pressure break of the present invention it is closed continuously plus sand blending tank, including knockout drum and it is connected to by communicating pipe
The agitator tank of bottom, the liquid CO in the knockout drum2By communicating pipe enter agitator tank and with the mortar in agitator tank
Mixing.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, wherein the knockout drum is provided with liquid CO2Enter
Mouth, gaseous state CO2Outlet, the agitator tank are provided with mortar entrance and built-in agitator, and the agitator is moved by agitator
Power inputs the external driving equipment of spindle nose, and the stirring pot bottom connection mixture export pipe, described mixture export pipe one end is
Mixture export, the other end rinse access port for auxiliary.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, the agitator left support wherein the agitator tank both ends are connected
Seat, agitator right support seat, the jackshaft both ends of the agitator are respectively placed in agitator left support seat, agitator right support seat
Interior and one end connects agitator power input shaft head, the driving equipment that is connected on agitator right support seat access support base.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, wherein the knockout drum is installed provided with liquid level gauge
Mouth, pressure gauge connection, safety valve installing port, pressure sensor interface.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, wherein the mixture export pipe is by being coupled supporting plate
It is connected to the stirring pot bottom.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, wherein the agitator tank bottom is provided with supporting leg.
The closed of dry method pressure break of the present invention continuously adds sand blending tank, due to sand and liquid CO2It is with pressure in agitator tank
Stirred in flowing, so both are well mixed, liquid CO2Band sand amount ratio (sand/liquid CO2) 10%-20% is increased to, together
When also greatly reduce tackifier dosage, reduce pressing crack construction cost, reduce formation contaminant, fracturing effect is substantially changed
It is kind.
Continuously sand blending tank is added to be described further the closed of dry method pressure break of the present invention below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is closed continuous plus sand blending tank the main structure diagram of dry method pressure break of the present invention.
Embodiment
As shown in figure 1, the closed of dry method pressure break of the present invention continuously adds sand blending tank including superposed for gas-liquid point
