Abstract
The invention discloses a device for air pressure oil well tubular column leak hunting. The device comprises an inflator, wherein a thread connector is arranged at one end of the inflator, a pressure gauge is connected to the other end of the inflator, and a valve and a compressor connector are arranged on the upper side and the lower side of the inflator respectively. The device for air pressure oil well tubular column leak hunting solves the problem that reasons for air pressure oil well tubular column leakage and loss are complex and are difficult to diagnose as a result, improves the diagnosis efficiency of air pressure oil well tubular column leakage and loss, is simple in structure, easy and convenient to operate, and high in practicability, provides a way for prolonging an oil well pump inspection cycle and reducing the rate of lying wells caused by leakage and loss, and improves production efficiency.
Description
Technical field
The invention belongs to oilfield chemical technical field, be specifically related to a kind of device leaking hunting for air pressure oil well pipe.
Background technology
Oil pipe is in oil recovery process, to flow oily passage, and working environment more complicated also will be born the additional fluctuating load producing in oil pumping system reciprocating motion process when bearing own wt.Oil pipe, except needs meet intensity, rigidity requirement, also should meet certain sealing performance requirement.The influence factor that affects oil pipe leakage is more, except stroke, jig frequency, and the salinity of formation water, outside the factors such as the content of corrosive deposit, the production and processing quality of oil pipe, specific well conditions, rod and tube partial-wear degree, thread abrasion degree is for causing tubing string to miss most important influence factor.Oil pipe leakage is the normal problem occurring in oil recovery process, because leakage reason complexity causes difficult diagnosis, thereby can not take timely and effectively control measures, has reduced production efficiency.
Summary of the invention
The object of this invention is to provide a kind of device leaking hunting for air pressure oil well pipe, solved the problem that causes difficult diagnosis due to air pressure oil well pipe leakage reason complexity.
The technical solution adopted in the present invention is: a kind of device leaking hunting for air pressure oil well pipe, comprise inflator, and one end of inflator is provided with hickey, and the other end of inflator is connected with pressure meter, and the both sides up and down of inflator are respectively arranged with valve and compressor interface.
Feature of the present invention is also,
On compressor interface, be connected with nut.
The invention has the beneficial effects as follows: a kind of device leaking hunting for air pressure oil well pipe of the present invention, solved the problem that causes difficult diagnosis due to air pressure oil well pipe leakage reason complexity, improved the diagnosis efficiency of air pressure oil well pipe leakage, simple in structure, easy and simple to handle, practical, for the lie reduction of well rate of the prolongation of oil pump pump detection period, leakage provides approach, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of apparatus structure schematic diagram leaking hunting for air pressure oil well pipe of the present invention.
In figure, 1. inflator, 2. hickey, 3. valve, 4. nut, 5. compressor interface, 6. pressure meter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of device leaking hunting for air pressure oil well pipe of the present invention, as shown in Figure 1, comprises inflator 1, and one end of inflator 1 is provided with hickey 2, and the other end of inflator 1 is connected with pressure meter 6, and the both sides up and down of inflator 1 are respectively arranged with valve 3 and compressor interface 5.
On compressor interface 5, be connected with nut 4.
During use, hickey 2 is connected with the termination of oil pipe, and guarantees that sealing joint is air tight, valve-off 3, the nut 4 of outwarding winding on compressor interface 5, is connected air compressor with compressor interface 5, by air compressor to the interior inflation of inflator 1 and then oil pipe is inflated, while being charged to a certain degree, stop, to the interior inflation of inflator 1, screwing the nut 4 on compressor interface 5, now observe the variation of pressure meter 6 upward pressure numerical value, if pressure remains unchanged, illustrate that tubing string is without leakage; If force value declines gradually, show that tubing string has leakage place, because tubing string internal pressure increases, leakage place has gas and oil ejection, now just can find fast leakage place, find after leakage place, the valve 3 of can outwarding winding is exitted, after the gas in tubing string and inflator 1 discharges, take off this air pressure oil well pipe leak detection method.
A kind of device leaking hunting for air pressure oil well pipe of the present invention has solved the problem that causes difficult diagnosis due to air pressure oil well pipe leakage reason complexity, improved the diagnosis efficiency of air pressure oil well pipe leakage, simple in structure, easy and simple to handle, practical, for the lie reduction of well rate of the prolongation of oil pump pump detection period, leakage provides approach, improved production efficiency.
