Abstract
An oil tube corrosion testing cylinder comprises an upper connector 1, an external cylinder 2 and a lower connector 5, and is characterized in that the inner wall of the external cylinder 2 is further equipped with a combined structure consisting of insulating rings 3 and testing rings 4 in multi-stage arrangement. The oil tube corrosion testing cylinder is simple in structure, easy in processing and convenient in operation, and can provide testing conditions of fine insulation property, sufficiently contacting with underground liquid and the like during usage, thereby being capable of truthfully reflecting corrosion of underground oil tubes, and increasing evaluation level of corrosion conditions.
Description
Technical field:
The utility model relates to a kind of oil field subsurface tool, especially for a kind of tube corrosion test barrel of oil, well.
Technical background:
Before the utility model, each oil field is for estimating oil, well downhole corrosion situation, often adopt lacing film formula test barrel to carry out the test of down-hole oil tube extent of corrosion, but test piece is less, insulating property are poor and it is abundant inadequately to contact with down-hole liquid because this device is gone up, and therefore can not reflect the situation of being corroded in the work of downhole oil tubing string really.
Summary of the invention:
The purpose of this utility model is: for oil field oil, well downhole corrosion status evaluation provide a kind of tube corrosion test barrel, because this device adopts the structure of test wrapper and the multistage assembled arrangement of dead ring, the test piece that has solved present lacing film formula test barrel existence is few, the insulation difference reaches and contacts problems such as insufficient with down-hole liquid, thereby can reflect the situation of being corroded in the work of downhole oil tubing string more really.
The purpose of this utility model realizes by following measure: a kind of tube corrosion test barrel comprise top connection, urceolus, lower sub, and the urceolus of elongate tubular upper end connects top connection, the lower end connects lower sub; It is characterized in that also being equipped with on the outer tube inner wall unitized construction that dead ring and test wrapper by the short tube shape constitute.
The purpose of this utility model can also realize by following measure: the unitized construction that dead ring and the test wrapper of installing on the outer tube inner wall by the short tube shape constitutes can be multistage arrangement.
The utility model is simple in structure, be easy to processing, easy to operate, can provide in the use good insulation and fully with test conditions such as down-hole liquid contacts, thereby can truly reflect downhole oil tubing string corrosion situation, improve corrosion condition evaluation level.
Description of drawings:
Fig. 1 is the structural representation of tube corrosion test barrel.
Embodiment:
The tube corrosion test barrel is made up of top connection 1, urceolus 2, dead ring 3, test wrapper 4, lower sub 5 etc., urceolus 2 upper ends of elongate tubular connect top connection 1, the lower end connects lower sub 5, arrange on its inwall the unitized construction that the 10-20 level is made of the dead ring 3 and the test wrapper 4 of short tube shape is installed.
The principle of work and the using method of tube corrosion test barrel are: elder generation is installed in it on tubing string by top connection 1, lower sub 5 and down in the precalculated position, down-hole, just can carries out the corrosion test in the tubing string course of normal operation; Because the internal diameter of tube corrosion test barrel approaches the tubing string internal diameter, and the multistage unitized construction that is made of dead ring 3 and test wrapper 4 has the good insulation performance, make test environment and tubing string working environment basic identical, thereby guaranteed that the tube corrosion test barrel can reflect the situation of being corroded in the downhole oil tubing string course of work really.
Claims (2)
1, a kind of tube corrosion test barrel, comprise top connection, urceolus, lower sub, and the urceolus of elongate tubular upper end connects top connection, the lower end connects lower sub, it is characterized in that: the unitized construction that dead ring and test wrapper by the short tube shape constitute also is installed on the outer tube inner wall.
2, tube corrosion test barrel according to claim 1 is characterized in that: the unitized construction that dead ring and the test wrapper of installing on the outer tube inner wall by the short tube shape constitutes can be multistage arrangement.
