Abstract
The utility model discloses a slide-sleeve type sampling device, relating to the technical field of oilfield oil testing working. The slide-sleeve type sampling device comprises a core shaft outer cylinder, wherein two outer cylinder bosses at top and bottom are fixedly arranged at the radial direction of the inner circumference of the core shaft outer cylinder; a hollow core shaft is arranged in the core shaft outer cylinder in a penetrating manner, a core shaft boss is fixedly arranged at the radial direction of the outer circumference of the core shaft, the core shaft boss is arranged between two outer cylinder bosses, the upper end of the core shaft is connected with an upper joint by screwed threads, the lower end of the core shaft is connected with a movable supporting ring by screwed threads, the movable supporting ring is provided with at least one axial through hole; the lower end of the core shaft outer cylinder is connected with a sample chamber outer cylinder by screwed threads, the lower end of the sample chamber outer cylinder is connected with the lower joint by screwed threads, the lower joint is connected with a fixed supporting ring by inner threads, the fixed supporting ring is provided with at least one axial through hole. An SQ3 sampler arranged outside of the sample chamber outer cylinder of the sampling device has no effect on the whole test channel. The sampling device is applied to the oilfield for solving the difficult problem that high pressure samples are taken in the thickened oil well and the high pour-point oil gas well.
Description
Technical field
The utility model relates to the technical field of oil field formation testing operation, relates in particular to a kind of sampling work that is used for the high pressure property sample of the higher oil gas well of viscous crude, high oil with fixed attention and the content of wax.
Background technology
At present, the method that prospect pit, development well are got the high pressure property sample is with steel wire the SQ3 sampler to be shipped to oil reservoir top, takes a sample.But in the higher oil gas well of viscous crude, high oil with fixed attention or the content of wax, in light weight because of sampler, be hampered easily, can't descend to the precalculated position, finish sampling work.Above-mentioned situation all has generation in the formation testing operation in An Feng, oil district such as day long.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of sleeve type sampler to be provided, the SQ3 sampler can being taken a sample in the higher oil gas well of viscous crude, high oil with fixed attention or the content of wax smoothly.
The purpose of this utility model is achieved in that the sleeve type sampler, comprises the mandrel urceolus, radially fixedly installs upper and lower two urceolus boss the interior week of mandrel urceolus; Place a hollow core shaft in the described mandrel urceolus, the outer periphery of mandrel fixedly installs the mandrel boss, described mandrel boss is arranged between two urceolus boss, the top connection that is threaded of the upper end of described mandrel, the lower end of the mandrel movable supporting ring that is threaded is provided with at least one axially extending bore on the movable supporting ring; The lower contact that is threaded of the lower end of the described mandrel urceolus specimen chamber urceolus that is threaded, the lower end of specimen chamber urceolus, the lower contact internal thread is connected and fixed support ring, on the described fixed support ring at least one axially extending bore is set.
When instrument is gone into the well, the SQ3 sampler is put into the specimen chamber urceolus of sleeve type sampler, be between movable supporting ring and the fixed support ring, when base sealed packer, the top connection and the mandrel of sleeve type sampler are descending, mandrel presses off the upper and lower valve of SQ3 sampler, formation fluid enters specimen chamber, during the EOT deblocking, the mandrel of sleeve type sampler is up, SQ3 sampler valve is closed specimen chamber under the effect of return spring, formation sample is stored in the sampler specimen chamber, takes ground to tubing string.The SQ3 sampler of placing in the sampler specimen chamber urceolus is to the not influence of whole test channel.This sampler is in field use, and solution heavy oil wells, height coagulate the difficult problem that the oil gas well is got the high pressure property sample.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be the sleeve type sampler, comprise mandrel urceolus 3, radially fixedly install upper and lower two urceolus boss 3-1 the interior week of mandrel urceolus 3.Place a hollow core shaft 2 in the mandrel urceolus 3, the outer periphery of mandrel 2 fixedly installs mandrel boss 2-1, mandrel boss 2-1 is arranged between two protruding 3-1 platforms of urceolus, the top connection 1 that is threaded of the upper end of mandrel 2, the lower end of the mandrel 2 movable supporting ring 4 that is threaded is provided with six first axially extending bore 4-1 on the movable supporting ring 4.The lower contact 6 that is threaded of the lower end of the mandrel urceolus 3 specimen chamber urceolus 5 that is threaded, the lower end of specimen chamber urceolus 5, lower contact 6 internal threads are connected and fixed support ring 7, and six second axially extending bore 7-1 are set on the fixed support ring 7.
Before sampler is gone into the well, the SQ3 sampler is put between the movable supporting ring 4 and fixed support ring 7 of sleeve type sampler, when set packer, the top connection 1 and the mandrel 2 that set load promotion sleeve type sampler are descending, and the movable supporting ring presses off the upper and lower valve that of SQ3 sampler, formation fluid enters specimen chamber, behind the EOT during deblocking, on carry load and make top connection 1 and mandrel 2 up, the SQ3 sampler is under the effect of return spring, valve is closed specimen chamber up and down, the formation sample of getting.
Claims (1)
1. the sleeve type sampler is characterized in that: comprise the mandrel urceolus, radially fixedly install upper and lower two urceolus boss the interior week of mandrel urceolus; Place a hollow core shaft in the described mandrel urceolus, the outer periphery of mandrel fixedly installs the mandrel boss, described mandrel boss is arranged between two urceolus boss, the top connection that is threaded of the upper end of described mandrel, the lower end of the mandrel movable supporting ring that is threaded is provided with at least one axially extending bore on the movable supporting ring; The lower contact that is threaded of the lower end of the described mandrel urceolus specimen chamber urceolus that is threaded, the lower end of specimen chamber urceolus, the lower contact internal thread is connected and fixed support ring, on the described fixed support ring at least one axially extending bore is set.
