Abstract
The utility model relates to an automatic charging pipe for preparing an acid liquid and a fracturing liquid. The automatic charging pipe is a venturi pipe which is composed of four sections of through pipes and is fine in the middle and bell-mouthed at two sides; the four sections of through pipes are respectively a shrinkable pipe, a throat pipe, a diffusion pipe and a straight pipe from top to bottom; the four pipes are sequentially communicated; a feeding pipe is obliquely inserted at the throat pipe and is communicated with the inside of the throat pipe. The automatic charging pipe is simple in structure, easy to mount and capable of absorbing powdery substances stably, uniformly and automatically, solves the problem of acid liquid and fracturing liquid preparation, also relieves the labor intensity of workers, and improves the production guarantee capability.
Description
Technical field
The utility model relates to a kind of device of pouring liquid, relates in particular to a kind of for preparation acid solution, of the fracturing fluid auto feed pipe.
Background technology
In Oil Field Exploration And Development, need reservoir reconstruction, carry out the acid fracturing operation, acid solution, fracturing fluid preparation raw material are: the additives such as 31% salt is joined, sustained release agent, cleanup additive, ferrous stability, emulsifying agent, the agent that becomes sticky, powder additive wherein, need slowly, evenly add as: glue crosslinking agent and the agent that becomes sticky, just can make qualified acidifying, the fracturing fluid wanted by abundant stirring.In the past, powder additive was manually poured labour intensity into large by manually slowly pouring preparing tank into, and it is irregular manually to pour speed into, easily causes hydrochloric acid to mix with powder additive inhomogeneous, acidifying, the underproof phenomenon of fracturing fluid often occur, the serious waste raw material, and delay the acid fracturing construction operation.
Summary of the invention
The purpose of this utility model be to propose a kind of can powder is stable, evenly automatically be drawn in pipe, what solve acid solution, fracturing fluid formulation problems is used for preparation acid solution, of the fracturing fluid auto feed pipe.
The purpose of this utility model is achieved in that preparation acid solution, of the fracturing fluid auto feed pipe, and it is thin by the centre that four sections siphunculus form, both sides are bell-mouthed Venturi tube, four sections siphunculus are respectively from top to bottom collapsible tube, trunnion, anemostat and straight tube, four pipes are communicated with successively, feed pipe is arranged, feed pipe and trunnion internal communication at trunnion place oblique cutting.
Owing to implementing technique scheme, the utility model is simple in structure, is easy to install, and it can be stablized powder, evenly automatically be drawn in pipe, has solved acid solution, fracturing fluid formulation problems, has alleviated simultaneously labor strength, improves and produces supportability.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is preparation acid solution, of the fracturing fluid auto feed tubular construction schematic diagram.
Legend: 1, adpting flange, 2, collapsible tube, 3, trunnion, 4, anemostat, 5, straight tube, 6, feed pipe.
The specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment
:As shown in Figure 1, preparation acid solution, of the fracturing fluid auto feed pipe is thin by the centre that four sections siphunculus form, and both sides are bell-mouthed Venturi tube.Four sections siphunculus are respectively from top to bottom that collapsible tube 2, trunnion 3, anemostat 4 and straight tube 5, four pipes are communicated with successively, are provided with adpting flange 1 at the lower port place of the upper port of collapsible tube 2 and straight tube 5.At trunnion 3 place's oblique cuttings, feed pipe 6 is arranged, feed pipe 6 and trunnion 3 internal communication.Collapsible tube 2 is that upper port is large, the oviduct that the lower end is young, and its lower port is connected with trunnion 3 upper port, and trunnion 3 is a pipe, and its lower port and upper end are young, and the upper port of the anemostat 4 that lower port is large connects, at anemostat 4 lower port place's connection straight tubes 5.
Feed pipe 6 is 45 ° of angles with trunnion 3 axis and stretches into trunnion 3, and the inner port of feed pipe 5 is angle, and it is towards anemostat 4.
In use, to trunnion 3, liquid accelerates to flow fluid, pressure decreased via collapsible tube 2.By trunnion 3, under the stopping of feed pipe 6, form a non-material area at the back side of feed pipe 6 this moment when fluid, and this place's pressure is lower than atmospheric pressure, and solid-state powder is adsorbed by feed pipe 6 and enters trunnion 3, is entered anemostat 4 by fluid removal.Because fluid is relatively stable in the interior flowing velocity of trunnion 3, thus relatively constant at trunnion 3 place's feed pipe 6 back sides, need not External Force Acting, powder will be by stable, evenly, automatically suck.When acidifying, fracturing fluid preparation, 31% hydrochloric acid is by centrifugal pump sucking-off in the acid storage tank, 31% hydrochloric acid enter Agitation Tank, pass through flange connect on Agitation Tank hydrochloric acid suction line, this feed pipe of at right angle setting, powder additive is sucked into this feed pipe as: glue crosslinking agent and the agent that becomes sticky by flexible pipe.Because hydrochloric acid is relatively stable in the interior flowing velocity of trunnion 3, so relatively constant at the trunnion 3 obstacle back sides, place " vacuum ", glue crosslinking agent and the agent that becomes sticky will be sucked equably, then stir by agitator, make acidifying, the fracturing fluid of satisfactory different size.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
