Abstract
The invention relates to a testing collecting reinjection full-closed blowout preventer and mainly solves the problem that liquid overflowing from an existing oilfield wellhead blowout preventer box is recovered under low efficiency and severe waste. The preventer is characterized in that a blowout prevention pipe (7) is connected to the top of an operation pipe (6), the sidewall of the blowout prevention pipe (7) is provided with a liquid outlet (8), the liquid outlet (8) is connected with a filter water tank (1) through a line (9), both a high level controller and a low level controller (3) are disposed inside the filter water tank (1) and connected with a high-pressure pump (4), and an outlet of the high-pressure pump (4) is connected with a logging valve arranged at the bottom of the operation pipe, through a one-way valve (5). The preventer is capable of thoroughly recovering the liquid and is high in recovery efficiency.
Description
Technical field
The present invention relates to oilfield, re-injection totally-enclosed blowout hookup is collected in a kind of test specifically.
Background technology
Oil field is when well logging, well testing, and well head can produce overflow, and the liquid of current overflow all adopts open recovery, and the fluid storage overflowed by blowout prevention box in container, then is transported to water treatment plant with oil truck, is used as sewage and processes.Such one side reclaims thorough, causes waste, simultaneously also contaminated environment.
Summary of the invention
The deficiency that during in order to overcome the liquids recovery of existing oil field shaft mouth blowout prevention box overflow, the low waste of organic efficiency is serious, the invention provides one test and collect re-injection totally-enclosed blowout hookup, the recovery of this test collection re-injection totally-enclosed blowout hookup is thorough, organic efficiency is high, free from environmental pollution.
Technical scheme of the present invention is: re-injection totally-enclosed blowout hookup is collected in a kind of test, comprise working pipe, lubricator is connected with above described working pipe, lubricator sidewall has fluid hole, fluid hole is connected with water tank with strainer by pipeline, be respectively arranged with high level controller and low level controller in described water tank with strainer, and high level controller and low level controller are all connected with high-pressure pump, and high pressure pump outlet is connected with the well logging valve bottom working pipe by one way valve.
The present invention has following beneficial effect: owing to taking such scheme, working pipe upper end connects lubricator, fluid hole on lubricator is connected with water tank with strainer, by the suction of high-pressure pump connected on water tank, make to form negative pressure in water tank and pipeline, thus make to form negative pressure in lubricator, make liquid in it by pipe flow will to water tank with strainer, be recycled into down-hole by high-pressure pump again, thus well liquid is reclaimed thoroughly, achieve no pollution operation.And overflow recovery and liquid re-injection are synchronously carried out, and shorten the activity duration, avoid waste, simultaneously according to spillway discharge number, automatically can control re-injection amount, efficiency is high.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
1-water tank with strainer in figure, 2-height level controller, 3-low level controller, 4-high-pressure pump, 5-one way valve, 6-working pipe, 7-lubricator, 8-fluid hole, 9-pipeline.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, re-injection totally-enclosed blowout hookup is collected in a kind of test, comprise working pipe 6, lubricator 7 is connected with above described working pipe 6, lubricator 7 sidewall has fluid hole 8, fluid hole 8 is connected with water tank with strainer 1 by pipeline 9, in described water tank with strainer 1, be respectively arranged with high level controller 2 and low level controller 3, and high level controller 2 and low level controller 3 are all connected with high-pressure pump 4, and high-pressure pump 4 is exported and is connected with the well logging valve bottom working pipe by one way valve 5.High level controller 2 and low level controller 3 can respond to the liquid level in water tank with strainer 1, and when liquid level attains to a high place controller 2, high-pressure pump 4 is opened, and outwards pumps liquid, and when liquid level is lower than low level controller 2, high-pressure pump 4 cuts out.
When well logging, well testing operation, allow logging instrument cable transfer to the operations such as each depth test parameter of down-hole of a few km, when opening well logging valve, the liquid of down-hole is under the pressure effect of 10-30Mpa, upwards flowing can be full of working pipe 6, and continue upward flow to lubricator 7.Now, high-pressure pump 4 is opened, under the swabbing action of high-pressure pump 4, the liquid of overflow enters into water tank with strainer 1 along pipeline 9, and the liquid after filtration is recycled in well by one way valve 5 through high-pressure pump 4 again, simultaneously can according to spillway discharge number, automatic control re-injection amount, efficiency is high.In the process, due to the effect of high-pressure pump 4, in lubricator 7, produce negative pressure, the liquid in it can be flowed away fast; Meanwhile, the liquid retained in working pipe after the end of job is also recyclable, achieves no pollution.
Claims (1)
1. re-injection totally-enclosed blowout hookup is collected in a test, comprise working pipe (6), it is characterized in that: described working pipe (6) top is connected with lubricator (7), lubricator (7) sidewall has fluid hole (8), fluid hole (8) is connected with water tank with strainer (1) by pipeline (9), high level controller (2) and low level controller (3) is respectively arranged with in described water tank with strainer (1), and high level controller (2) and low level controller (3) are all connected with high-pressure pump (4), and high-pressure pump (4) outlet is connected with the well logging valve bottom working pipe by one way valve (5).
