Abstract
A pressure measuring and water distributing double-function injection allocator belongs to a downhole water injection tool. Two dual fishing slots (11) are arranged at two sides of a strengthening body (3), the strengthening body (3) is positioned inside an upper connecting sleeve (2-1), an eccentric water distributing hole (8) and an eccentric pressure measuring hole (9) are disposes inside a main body (4), two water eyes (12) are provided on an internal hole wall of the main body, a channel central hole (13) is respectively communicated with the eccentric water distributing hole and the eccentric pressure measuring hole through the water eyes (12) and a communicating pore canal (10) is arranged inside the main body (4). The utility model can measure the flowing pressure outside the oil pipe; realize the direct measuring of single-layer flow rate of a water injection well with large injection rate differences between multi-layer and single layer injections; measure the flow rate of each layer directly with small measuring error, high distributing efficiency and qualification rate and without any mutual interference among layers; solve the problems that the cup is rubbed in the via hole and the pressure is suppressed during the testing and sealing check of the water injection well and realize the layering testing and sealing check without well off and liquid flow discharging.
Description
Technical field: the utility model relates to a kind of oil field underground water-injection instrument, and it can realize delaminating pressure testing and quantitative injection simultaneously.
Background technology: what the oil field dispenser extensively adopted at present is 665 type eccentric injection mandrels, main body has an eccentric orfice, the eccentric orfice blanking plug of packing into during normal water filling, the eccentric orfice top and the bottom communicate with central tube, the outer wall center is porose to be interlinked to the outside with pipe, a centralizer body is arranged at main body top, and centralizer body is provided with a pulling groove, is used to set upright when the pulling blanking plug.When pressure measurement, earlier first wife's water slug device is pulled out, drop into stopper type minor diameter electronic memory pressure probe, manometric pressure transmission hole is directly aimed at oil reservoir, to measure the static pressure data.Want full well closing well when surveying individual layer pressure.When surveying the outer flowing pressure of individual layer oil pipe other interval is blocked with blanking plug, replace, also can't record flowing pressure outside the oil pipe at present with surveying the pipe internal pressure.When measurement of discharge, also can't directly record at present the flow of individual layer, be lowered to testing seal section and flow meter but adopt, measure each interval flow from bottom to top step by step, last layer flow is full well yield.By adopting diminishing method to calculate behind the full well yield that measures and obtaining the individual layer flow indirectly, this method exists than mistake, has interlayer interference between each layer when carrying out the flow rate test allotment, causes allotment efficient lower, the problem that qualification rate is not high.
Summary of the invention: the utility model has been developed and a kind ofly can have been measured the outer flowing pressure of oil pipe, realizes that the big water injection well of injection rate gap between multilayer, the individual layer directly measures the difunctional injection allocation device of pressure measurement, water distribution of individual layer flow.The utility model has comprised top connection 1, upper joint sleeve 2-1, main body 4, support 5, guide way 6, lower joint sleeve 2-2, lower contact 7, the internal thread on upper joint sleeve 2-1 top is connected with the external screw thread of top connection 1 bottom, the internal thread of upper joint sleeve 2-1 bottom is connected with the external screw thread on main body 4 tops, the external screw thread of main body 4 bottoms is connected with the internal thread on lower joint sleeve 2-2 top, the internal thread of adapter sleeve 2-2 bottom is connected with the external screw thread on lower contact 7 tops, the top of support 5 is connected with the bottom of main body 4, and guide way 6 is fixed on the inside of support 5.It has also comprised centralizer body 3, the both sides of centralizer body 3 are provided with bilateral pulling groove 11, centralizer body 3 is fixed on the inside of upper joint sleeve 2-1, eccentric center water-distributing hole 8 and eccentric pressure tap 9 are located at the inside of main body 4, the inner hole wall of main body 4 is provided with two hydrophthalmias 12, channel center hole 13 is connected with eccentric center water-distributing hole 8 and eccentric pressure tap 9 respectively by hydrophthalmia 12, and the inside of main body 4 is provided with connected pore channel 10.The utility model can measure the outer flowing pressure of oil pipe; Realize that the big water injection well of injection rate gap directly measures the individual layer flow between multilayer, the individual layer; Owing to can directly record the flow of each layer, therefore measure error is less, do not interfere with each other between each layer, so allotment efficient height, the qualification rate height, solve injection well testing, the testing seal section via hole is scraped leather cup and the problem that builds the pressure when testing envelope, has realized that responding curve of well, not tapping stream also can carry out zonal testing and test the purpose of envelope.
Description of drawings: Fig. 1 is a structural representation of the present utility model.Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the B-B sectional view of Fig. 1.
The specific embodiment one: this specific embodiment is by top connection 1, upper joint sleeve 2-1, lower joint sleeve 2-2, centralizer body 3, main body 4, support 5, guide way 6, lower contact 7 is formed, the internal thread on upper joint sleeve 2-1 top is connected with the external screw thread of top connection 1 bottom, the outer surface of upper of upper joint sleeve 2-1 is provided with O RunddichtringO 14-1, the internal thread of upper joint sleeve 2-1 bottom is connected with the external screw thread on main body 4 tops, the lower external face of upper joint sleeve 2-1 is provided with O RunddichtringO 14-2, the external screw thread of main body 4 bottoms is connected with the internal thread on lower joint sleeve 2-2 top, the internal thread of adapter sleeve 2-2 bottom is connected with the external screw thread on lower contact 7 tops, the top of support 5 is connected with the bottom of main body 4, guide way 6 is fixed on the inside of support 5, eccentric center water-distributing hole 8 and eccentric pressure tap 9 are located at the inside of main body 4, centralizer body 3 is provided with bilateral pulling groove 11, eccentric center water-distributing hole 8 is used to sit pressure gauge, the pressure gauge passage seals with blanking plug under the situation of measuring pressure not, pull blanking plug during pressure measurement out and change the minor diameter pressure gauge into, the blanking plug that also can drop into the band water nozzle to the not enough interval of water injection rate carries out water filling, increases water injection rate; The inner hole wall of main body 4 is provided with two hydrophthalmias 12, hydrophthalmia 12 is communicated with channel center hole 13 respectively with eccentric center water-distributing hole 8 and eccentric pressure tap 9, after testing seal section sits on the position, just aim at the central tube inlet opening between two groups of sealing rings of testing seal section, therefore can record the parameter of the individual layer section of this layer, the inside of main body 4 is provided with connected pore channel 10, when this interval is tested, connected pore channel 10 makes the working condition of other layer constant substantially, and is less to the influence of other layer.
