Abstract
The utility model discloses a bridge two-cup testing seal section mainly comprising a collar, a center tube, an outer center tube, a short tube, a grapple and a wheel-locking assembly etc. The device is characterized in that outer walls of the upper and lower ends of the outer center tube are provided with an upper cup and a lower cup respectively. Caps fix the two ends of the upper cup and the lower cup respectively. A water injection hole and a drain hole are arranged in the center tube. The utility model provides an instrument for monolayer testing or stratification testing of water injection well for oil field and has the advantages of flexible operation and accurate measurement.
Description
One, technical field: the utility model relates to a kind of oilfield test downhole hardware, particularly a kind of bridge-type double leather cup testing seal section.
Two, background technology: the downhole testing of present water injection well in oil fields generally adopts the single-skin drum bowl to carry the extension testing seal section and measures, this method can't be tested separately a certain individual layer of water injection string, and the interfering data error is big between test middle level and the layer, and working strength of workers is big.
Three, summary of the invention: the purpose of this utility model just is to provide a kind of double leather cup seal section testing arrangement---the bridge-type double leather cup testing seal section that can realize that individual layer or layering are measured.Technical solution of the present utility model is: described double leather cup testing seal section, mainly comprise box cupling, central tube, exterior central tube, short tube, claw and lock wheel assembly etc., on the outer wall at the upper and lower side place of exterior central tube, be respectively arranged with leather cup and down cup, adopt pressure cap to fix respectively at the two ends of last leather cup and down cup, in central tube, offer water injection hole and plug hole; On the central tube of water injection hole and plug hole bottom, offer weep hole that is communicated with water injection hole and the drain hole that is communicated with plug hole respectively, in plug hole, be provided with sealing-plug.The utility model modern design, rational in infrastructure, for the oil field provides a kind of instrument that can carry out individual layer or zonal testing to water injection well, adopt double leather cup seal section technology, can under the situation that does not stop water filling, measure arbitrarily according to required survey interval, thus the error that produces when having avoided carrying out complicated procedures that full well yield and each interval data successively decrease and error of calculation.The utlity model has flexible operation easy, measure accurate advantage.
Four, description of drawings: Fig. 1 is the utility model embodiment master TV structure cross-sectional schematic.
Five, the specific embodiment: with reference to accompanying drawing, described double leather cup testing seal section, mainly comprise box cupling 1, central tube 2, exterior central tube 3, short tube 4, claw 5 and lock wheel assembly 6 etc., on the outer wall at the upper and lower side place of exterior central tube 3, be respectively arranged with leather cup 7 and down cup 8, adopt pressure cap 9 fixing at the two ends of last leather cup 7 and down cup 8 respectively, in central tube 2, offer a water injection hole 10 and three plug holees 11.On the central tube 2 at water injection hole 10 and place, plug hole 11 bottoms, offer weep hole 12 that is connected with water injection hole 10 and the drain hole 13 that is communicated with plug hole 11 respectively, in plug hole 11, be provided with sealing-plug 14.
The utility model is when measuring, and last down cup spreading is sealed injection well downhole flow regulator main body water filling port upper-lower seal position, and liquid enters the measurement passage by the flow meter that is connected on the box cupling, enters injection well downhole flow regulator main body water filling port by water injection hole.In measuring process, because the up and down O-ring seal effect in the ring-like space of cup packing and exterior central tube endoporus and central tube cylindrical, make that liquid can no seepage and no leakage; In addition, all the other liquid flow into lower floor's (this liquid is without metering) by three plug holees and the plug hole on the injection well downhole flow regulator on central tube top, thereby have accomplished that continuous data is accurate, error free generation when guaranteeing to test.
