Description
Technical field
The utility model relates to a kind of oilfield exploitation field flow control screen pipe, particularly a kind of inboard have stationary support seam the filter ruffle flow control screen pipe.
Background technology
In the oil exploitation operation, the sand control that screen casing (claiming anti-sandpipe again) is used for oil well, gas well, horizontal well, straight well and directional well filters.Screen casing includes parent tube, is evenly distributed with the inlet of through hole as parent tube on parent tube, and parent tube is set with filter pipe outward, and the circumferential weld between parent tube and the filter pipe is the water conservancy diversion layer.
Because the viscosity of water is far smaller than crude oil, and factor such as stratum heterogeneous body, exist very serious well water problem in the crude oil production, had a strong impact on the economic benefit in oil field.
The use flow control screen pipe is the efficient ways that goes out water problems in a large number that the reasons such as high viscosity ratio of oil and water of solution oil reservoir cause.As a kind of high-efficiency flow control screen pipe, screen casing is provided with a flow control device, and the inlet of described flow control device communicates with the water conservancy diversion layer, and the outlet of flow control device communicates with the parent tube inlet.During use, will cross filter ruffle two ends and external isolation by the screen casing end ring, fluid can only cover into the water conservancy diversion layer by filtration.Because the water conservancy diversion layer communicates with the inlet of flow control device, the outlet of flow control device communicates with the parent tube inlet, thereby in the oil recovery manufacturing process, the route that fluid flows through was that filter ruffle, water conservancy diversion layer, flow control device inlet, flow control device, flow control device outlet, parent tube inlet enter parent tube successively.This is unique path, and in addition fluid does not have other paths to flow in the parent tube outside screen casing.
This flow control screen pipe has played the effect of the bigger variation of control flow to a certain extent, reaches the purpose of control stream.It can determine well that the reasons such as high viscosity ratio of oil and water of the oil reservoir that exists in the prior art cause goes out water problems in a large number.
The gap of water conservancy diversion layer is very little in the screen casing, is generally the 1-5 millimeter, and the length of flow of crude oil in the water conservancy diversion layer can reach 4-9m when recovering the oil, and the flow resistance of crude oil in the water conservancy diversion layer is bigger, the whether unimpeded output that directly affects oil recovery of water conservancy diversion layer.
In order to guarantee the unimpeded of water conservancy diversion layer, make the water conservancy diversion layer not closed with the rising of peripheral pressure, often adopt the method that vertical muscle evenly is set in the water conservancy diversion layer, vertical muscle is played a supporting role when filter pipe is subjected to peripheral pressure extrusion, guarantee that the water conservancy diversion layer is not closed, guaranteed the unimpeded of water conservancy diversion layer.
Uniform vertical muscle in the water conservancy diversion layer, the form of its filter pipe has two kinds, and a kind of is the external surface that vertical muscle is distributed in parent tube, and wrapping wire forms filter pipe outside parent tube again, and this needs special-purpose filament winding device, process equipment costliness.Another kind is that filter pipe is the metal net; at metal net liner internal protective cover; metal net and internal protective cover are enclosed within on the parent tube of the vertical muscle of band; this method uses material many on the one hand; on the other hand because the installation rate of vertical muscle is slow; the size that vertical muscle is installed is nonstandard, error is big, causes with the parent tube external diameter error of vertical muscle greatly, has increased the difficulty of cover filter pipe.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, provide the seam that there is stationary support a kind of inboard the filter ruffle flow control screen pipe, it is simple in structure, cost is low, manufacturing process is simplified greatly, crudy is convenient to control, it can guarantee that the water conservancy diversion layer is not closed with the rising of ambient pressure, guaranteed the unimpeded of water conservancy diversion layer, and the reasons such as high viscosity ratio of oil and water that can solve the oil reservoir that exists in the oil exploitation process well cause goes out water problems in a large number, satisfies actual field produces requirement.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of inboard of the utility model have stationary support seam the filter ruffle flow control screen pipe, comprise screen casing and the flow control device that is installed on the screen casing, described screen casing comprises parent tube, and described parent tube is provided with the parent tube inlet, parent tube is set with filter pipe outward, and the circumferential weld between parent tube and the filter pipe is the water conservancy diversion layer; Described flow control device comprises the outlet of inlet, control stream runner and the flow control device of flow control device, and the inlet of described flow control device communicates with the water conservancy diversion layer, and the outlet of flow control device communicates with the parent tube inlet; Described filter pipe is a metal tube, evenly is provided with fixed support block to convex guide fluid layer direction on the described metal tube tube wall circumference, and described metal tube is provided with the bar seam.
To the punching press of convex guide fluid layer direction equally distributed boss is arranged on the described metal tube tube wall circumference, the height of boss is greater than forming the side direction seam between thickness, boss and the metal tube of metal tube tube wall.
Described side direction seam distributes along axis.Perhaps, described side direction seam distributes along helix.
Screen casing manufacturing process described in the utility model is simple, cost is low, it is provided with stationary support in metal filtration cover inboard, metal filtration has put the bar seam, stationary support can be punching out, also can be laser and blade cut the system or directly put the welding stationary support at metal filtration, the one side that stationary support is arranged with metal sheet is welded into cylinder to the curls inward circle again, be enclosed within the parent tube external surface, played the effect of vertical muscle in the water conservancy diversion layer of stationary support between filter pipe and parent tube of inner process, when filter pipe was subjected to the external force extruding, stationary support was played a supporting role, make the water conservancy diversion layer not closed, guaranteed the unimpeded of water conservancy diversion layer with the rising of peripheral pressure.The bar seam has guaranteed the requirement of screen casing filtering accuracy.Because metal sheet directly as filter pipe, has splendid bulk strength and non-deformability.Because the supporting role to the stationary support of inner process has guaranteed the unimpeded of water conservancy diversion layer, has reduced the flow resistance of crude oil in the water conservancy diversion layer, helps improving oil and gas production.Simultaneously flow control device can solve well that the high viscosity ratio of oil and water of the oil reservoir that exists in the oil exploitation process causes goes out water problems in a large number.
