Description

The test blanking plug of electric submersible pump
Technical field
It the utility model is related to test device, more particularly to a kind of test blanking plug for electric submersible pump.
Background technology
In order to ensure the reasonability of oil reservoir development, it is necessary to periodically test specific oil well, oil reservoir in oil reservoir, so as to Tracking obtains underground and respectively produces the related dynamic parameters such as layer temperature of bit stream body, pressure, density and fluid properties.And wireline test It is then a kind of dynamic monitoring mode in electric submersible pump normal operation production process.
At present, in order to ensure electric pump runs well, generally, production blanking plug is replaced using test blanking plug.Existing survey Examination blanking plug mainly has tower disc type test blanking plug and drift tube type test blanking plug two types;The two kinds of blanking plug sheet Using sealing surface and the sealing ring sealing matched with seating nipple inwall outside body;Wherein, for the cable seal of inside, tower tray The center of formula test blanking plug uses tower rubber seal packing_seal, and drift tube type test blanking plug then uses flow tube from seal Top is inserted, and passes through the sealing of seal and sealing ring.
Blanking plug is tested for tower disc type, before going into the well, is first passed through cable from tower rubber seal packing center, it is tower Rubber seal packing is then seated in test blanking plug body, regulation test blanking plug fishing head, extrudes tower rubber seal packing And deformation expansion is produced, so as to the sealing of complete paired cable.When it is elastic regulation it is moderate when, can make cable freely up and down run and Energy hermetically-sealed cable, so as to realize testing requirement.But at the scene during practice of construction, due to by different well temperatures, pressure Power influences, and expansion or compression are different, is not enough leaked or rubber seal packing is wear-resisting, otherwise locking cable can not On put and put, so as to have to do over again, regulation is re-started to test blanking plug.And drift tube type test blanking plug, before going into the well, Flow tube is inserted at the top of seal body, and is by the sealing of seal and sealing ring, inwall and the cable gap of flow tube Within 0.1-0.2mm, there is hermetically-sealed cable effect.At the scene in actual job, because test cable and flow tube are often because repeatedly Removing and a certain amount of abrasion be present, and put on downhole cable when putting, cable and flow tube deform upon in the presence of pulling force, because This, causes the inwall of actual single metal flowtube and the appearance of cable gap bigger than normal, so as to make actual sealing effectiveness not good enough, easily go out Existing leakage phenomenon, so as to cause the test data distortion or invalid collected;If leaking seriously for a long time, electric pump is also resulted in There is abnormal even failure and burns phenomenon in operating.
Utility model content
Main purpose of the present utility model is to overcome disadvantages mentioned above existing for prior art, and provides a kind of improved electricity The test blanking plug of latent pump, it can not only reduce elastic to blob of viscose regulation requirement and the inwall required precision of flow tube, make existing Field use is easier;Solves the generation that the bad phenomenons such as leakage, locking cable occur;Moreover, make sealed packing after going into the well It will not fall off, greatly reduce packing processing cost, meanwhile, maintaining is simpler;It ensure that the normal electricity that smoothly completes is dived Pump sump is tested.
The purpose of this utility model is realized by following technical scheme:
A kind of test blanking plug of electric submersible pump, it is characterised in that:Including:One fishing head, the connection on fishing head Set and blob of viscose seat, wherein, a small blob of viscose is seated in blob of viscose seat, and one-level cable seal is formed, underground dilatancy is not embraced Dead cable;And flow tube seat is installed on blob of viscose seat, the seal body being connected with flow tube, inserted with flow tube in flow tube seat, and pass through Two level cable seal is formed with the cable at flow tube center;Return spring, dummy piston and pressure release are assembled with seal body successively Push rod;The surface of seal body is provided with sealed packing groove, and lower connector is provided with seal body.
The fishing head has the centre bore salvaged using conventional tool.
The inwall of flow tube and cable gap are 0.1-0.2mm scopes.
The sealed packing groove is dovetail type, to ensure that sealed packing will not fall off after going into the well, with seating nipple inwall The sealing surface matched somebody with somebody forms sealing.
The beneficial effects of the utility model:The utility model is because using above-mentioned technical proposal, it can not only be reduced Regulation elastic to blob of viscose requires and the inwall required precision of flow tube, makes onsite application easier;Solve generation leakage, locking The generation of the bad phenomenons such as cable;Moreover, will not fall off sealed packing after going into the well, packing processing cost is greatly reduced, together When, maintaining is simpler;It ensure that the normal electric immersible pump well that smoothly completes is tested.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Major Symbol explanation in figure:
1. fishing head, 2. adapter sleeves, 3. blob of viscose seats, 4. small blob of viscoses, 5. flow tube seats, 6. flow tubes, 7. seal bodies, 8. returns Spring, 9. dummy pistons, 10. pressure release push rods, 11. sealed packing grooves, 12. lower connectors, 13. pins.
Embodiment
As shown in figure 1, the utility model includes:One fishing head 1, using screwed connection mode be arranged on fishing head 1 on Adapter sleeve 2 and blob of viscose seat 3, wherein, a small blob of viscose 4 is seated in blob of viscose seat 3, and one-level cable seal is formed, become underground expansion Shape can not locking cable;And flow tube seat 5 is provided with using screwed connection mode on blob of viscose seat 3, inserted with flow tube 6 in flow tube seat 5, The seal body 7 being connected with flow tube 6, and by forming two level cable seal with the cable at the center of flow tube 6;Due to small blob of viscose 4 and The double containment of flow tube 6 complements each other respectively up and down, therefore, reduces the inwall precision of regulation requirement elastic to small blob of viscose 4 and flow tube 6 It is required that;Return spring 8, dummy piston 9 and pressure release push rod 10 are assembled with seal body 7 successively;The surface of seal body 7 is provided with Sealed packing groove 11, lower connector 12 is provided with by screwed connection mode in seal body 7.
