Description
Technical field
This utility model belongs to petroleum gas engineering field, specifically, is to be related to the well logging of horizontal well coiled tubing to survey
Study industry and and downhole tool making field.
Background technology
The method of horizontal wellbore logging testing tool conveying mainly adopts down-hole electric traction device (crawl device) conveying method, oil pipe
Conveying method, coiled tubing conveying method and Hydraulic transportation method etc..This several carrying method is every kind of have respective pluses and minuses it is adaptable to
The horizontal well of different well logging purposes.
According to literature survey, in terms of net horizontal section logger conveying technology, be summed up can be divided into following several：
(1) oil pipe (drilling rod) conveying technology：Logger is transported to by drilling rod or oil pipe using rig or working rig
Test purpose depth, and using mud circulation power, well cable butting instrument is combined with logger.This technology is current
Conveying technology the most ripe, but may not apply to Production Logging in Horizontal Wells, and fragile production logging instrument.The method simultaneously
Need rig or workover rig and drilling rod or oil pipe carry out logging operation, high cost, under enter slow, workload is big, labor intensity
Height, the time is long, and efficiency is low.
(2) Hydraulic transportation technology：Using the motive force of water, logger is pushed into horizontal segment after High angle section is hampered
End, due to being to be conveyed in sleeve pipe, construction operation is safe and reliable for Hydraulic transportation method.But this technology can only adopt
Oil pipe logging method is it is impossible to measure the oil of horizontal interval, gas and water percentage ratio, and easily oil reservoir is polluted, and fed distance is short,
It is not suitable for well logging with pressure.
(3) electric traction device (crawl device) conveying technology：Connect logger using crawl device, after High angle section is hampered
Powered to crawl device by ground system, logger is transported to by interval of interest by crawl device.The method is subject to instruments weight
Impact, crawl device maximum thrust in (200～300) kg, be not therefore suitable for open hole well, heavy oil wells, slim hole well well logging.With
When the method not only power is low, and high cost, and there is certain risk.
(4) coiled tubing conveying technology：In advance cable (optical fiber) is penetrated in coiled tubing, logger is mounted directly
In the lower end of coiled tubing, injection head promotes coiled tubing to be lowered in well, promotes logger to be lowered into measurement well section, to not
With the logger wide adaptability of size, cased well, annular space, through tubing log operation can be carried out.
In above-mentioned several logger conveying technology, coiled tubing logging technique has other in horizontal well performance testing
It is considered to be most rising production logging technology, its advantage is as follows for the incomparable advantage of logging method：
(1) in the conveying underground logging instrument instrument of horizontal well middle and long distance and short-range spiral twisted tube can be passed through
Section；
(2) when logger is in down-hole, mud conditioning can be carried out by coiled tubing, assessment result on the spot；
(3) logging tool removes steadily, can achieve multiple logging speed follow-on tests；
(4) logging cable reliability is higher, and can replacing logging tool quickly and easily；
(5) with pressure or have operation in the case of liquor stream, and pressure can be maintained constant, reduce blowout dangerous.
Abroad, coiled tubing well logging becomes a kind of new horizontal wellbore logging Technology, but should in CHINESE REGION
With less.At home, oil-water well dynamic monitoring production logging with pressure and coiled tubing are worn to the kit of cable, domestic
Scientific research personnel then also need to further study.
