Description
Technical field
The utility model relates to a kind of oil production method of field of petroleum exploitation, particularly relate to a kind of multistage oil rig.
Background technology
Existing oil extraction in oil field method many employings sucker rod pump, hydraulic pump and electric submersible pump three kinds of mechanical oil recovery methods.These three kinds of methods respectively have pluses and minuses, about wherein the oil recovery degree of depth of sucker rod pump is limited in 5000m, about the oil recovery degree of depth of hydraulic pump is limited in 5000m, the oil recovery degree of depth of electric submersible pump is limited in about 3000 meters, the darkest oil recovery degree of depth in current domestic land can only reach 5000m, does not have suitable oil production method for the ultradeep well exceeding 5000m.A kind of multistage oil rig is now proposed, sucker rod pump and rodless pump are combined, form multistage extracting device of oil, the mode of series connection is adopted to play the ability of different extracting device of oil, possess the advantages such as device is simple, the oil pumping degree of depth is dark, the ultradeep well of more than 5000m can be applied to, still be applicable to the exploitation of the following oil well of 5000m simultaneously.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of multistage oil rig, mining depth cannot exceed the problem of the oil well of 5000m, provide a kind of new oil pumping method sucker rod pump and rodless pump combined in prior art.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of multistage oil rig, include transformer, the switchboard be connected with transformer, the junction box be connected with switchboard, the land cable be connected with junction box, the underground cable be connected with land cable, the electric submersible pump be connected with underground cable, the electric submersible pump oil pipe be connected with electric submersible pump, the tube connector be connected with electric submersible pump oil pipe, be connected with tube connector have bar plunger displacement pump, with the sucker rod having bar plunger displacement pump to be connected, the oil pumper that is connected with sucker rod.
In the multistage oil rig of one described in the utility model, described sucker rod length is 1000-5000 rice.
In the multistage oil rig of one described in the utility model, the length of described electric submersible pump oil pipe is 1000-5000 rice.
In the multistage oil rig of one described in the utility model, the oil that described electric submersible pump is extracted out successively by electric submersible pump oil pipe, tube connector, have bar plunger displacement pump, sucker rod.
In the multistage oil rig of one described in the utility model, described electric submersible pump, electric submersible pump oil pipe can arrange multiple by the mode of alternately series connection.
Implement the multistage oil rig of one described in the utility model, there is following beneficial effect:
The oil that electric submersible pump is extracted out enters in tube connector by electric submersible pump oil pipe, and sucker rod is pumped from tube connector by there being bar plunger displacement pump.The lower-continuous mapping of pumping is increased substantially.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of multistage oil rig described in the utility model; In figure, 1-transformer, 2-switchboard, 3-junction box, 4-land cable, 5-underground cable, 6-oil pumper, 7-ground, 8-sucker rod, 9-have bar plunger displacement pump, 10-tube connector, 11-electric submersible pump oil pipe, 12-electric submersible pump, 13-oil reservoir.
Detailed description of the invention
As shown in Figure 1, in the preferred embodiment of a kind of multistage oil rig described in the utility model, include transformer 1, the switchboard 2 be connected with transformer 1, the junction box 3 be connected with switchboard 2, the land cable 4 be connected with junction box 3, the underground cable 5 be connected with land cable 4, the electric submersible pump 12 be connected with underground cable 5, the electric submersible pump oil pipe 11 be connected with electric submersible pump 2, the tube connector 10 be connected with electric submersible pump oil pipe 11, be connected with tube connector 10 have bar plunger displacement pump 9, with the sucker rod 8 having bar plunger displacement pump 9 to be connected, the oil pumper 6 that is connected with sucker rod 8.
Concrete, ground 7 is followed successively by with the lower part order of connection from top to bottom: sucker rod 8, have bar plunger displacement pump 9, tube connector 10, electric submersible pump oil pipe 11.
In this preferred embodiment, ground power supply by land cable 4 and underground cable 5 by delivery of electrical energy to electric submersible pump 12, electric submersible pump 12 by the oil obtd in oil reservoir 13 to electric submersible pump oil pipe 11, tube connector 10 is entered after oil in electric submersible pump oil pipe 11 is full, when the oil in tube connector 10 is close to after full, oil pumper 6 starts, and drives sucker rod 8 to move back and forth, drives and have bar plunger displacement pump 9 to pump from tube connector 10.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with the content of claims.
