Abstract
The invention relates to the technical field of production test for horizontal wells, in particular to a production test system for mechanized horizontal well coiled tubing. A test cable in the system is installed inside a coiled tube 32mm in diameter. A test meter is connected to the lower end of the test cable. The coiled tube 32mm in diameter is wound to a cylinder of a coiled tubing operating machine. An injection head of the coiled tubing operation machine is disposed on an injection head support. An outlet of a guide tube of the injection head support is aligned with a test hole. The coiled tube 32mm in diameter with the test meter is tripped into an inner horizontal well segment through the injection head, the guide tube, the test hole and a downhole guard tube 49mm in diameter. The system has the advantages that the test cable is protected effectively, the test meter can be smoothly tripped into the horizontal well segment for testing without affecting normal production of an oil well, and the defect that the existing test meter and cable cannot be tripped into the horizontal well segment by the gravity method is overcome.
Description
Technical field:
The present invention relates to a kind of horizontal well production test technical field, particularly a kind of machine is adopted horizontal well coiled tubing production test system.
Background technology:
Machine is adopted a maturation, the applicable technology of horizontal well as oil-gas field development, worldwide day by day is widely applied, and the production performance evaluation measuring technology of machine being adopted to horizontal well is still immature at home.And machine adopt the difficult point of horizontal well production test be exactly how by tester in the situation that do not affect the normal net horizontal section of producing G.I.H of oil well, current conventionally test technique can't realize that machine adopts the test under the horizontal well production status at all, causes machine to adopt the subsequent development of horizontal well seriously limited.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of machine and adopts horizontal well coiled tubing production test system; this system has realized effective protection test cable, can be in the situation that do not affect normal production of oil well and tester is lowered to net horizontal section is smoothly tested.Having overcome existing tester and cable relies on gravity can't be lowered to the deficiency of net horizontal section.
The technical solution used in the present invention is: a kind of machine is adopted horizontal well coiled tubing production test system, comprises test cable, diameter 32mm coiled tubing, tester and coild tubing unit; Test cable is arranged in diameter 32mm coiled tubing, test cable lower end connecting test instrument, diameter 32mm coiled tubing is wrapped on the cylinder of coild tubing unit, injection head on coild tubing unit is placed on injection head support frame, instrument connection is aimed in the outlet of the guide pipe of injection head support frame, carries the diameter 32mm coiled tubing of tester by injection head, guide pipe, instrument connection and down-hole diameter 49mm pillar G.I.H horizontal segment.
Diameter 32mm coiled tubing is made by No. 80 steel, and wall thickness is 3mm, and yield strength is 552MPa.
The invention has the beneficial effects as follows: the present invention is arranged on the mode in diameter 32mm coiled tubing owing to having adopted by test cable; thereby have and can tester be lowered to the function that net horizontal section is tested smoothly in the situation that do not affect normal production of oil well, effectively protect test cable.
The accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
The specific embodiment:
As shown in Figure 1, a kind of machine is adopted horizontal well coiled tubing production test system, comprises test cable, diameter 32mm coiled tubing 1, tester 4 and coild tubing unit 7; Test cable is arranged in diameter 32mm coiled tubing 1, test cable lower end connecting test instrument 4, diameter 32mm coiled tubing 1 is wrapped on the cylinder 5 of coild tubing unit 7, injection head 9 on coild tubing unit 7 is placed on injection head support frame 2, instrument connection 3 is aimed in the outlet of the guide pipe 10 of injection head support frame 2, carries the diameter 32mm coiled tubing 1 of tester 4 by injection head 9, guide pipe 10, instrument connection 3 and down-hole diameter 49mm pillar 6 G.I.H horizontal segments.Diameter 32mm coiled tubing 1 is made by No. 80 steel, and wall thickness is 3mm, and yield strength is 552MPa.
Be understandable that, above about specific descriptions of the present invention, only for being described, the present invention not is limited to the described technical scheme of the embodiment of the present invention, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the present invention, to reach identical technique effect; Use needs as long as meet, all within protection scope of the present invention.
