Description
Technical field
It the utility model is related to a kind of paraffin scraper.
Background technology
Crude oil in China is rich in wax, and most of wax content in crude oil are higher, most of crude oil extraction paraffin content more than 20%,
Crude oil of the paraffin content more than 10% accounts for the 90% of whole output crude oil.During crude oil production, the stone that is dissolved in crude oil
Wax can be separated out with the reduction of ambient pressure and temperature from natural gas, and is grown up in the form of crystal and assembled and be deposited on oil
On tube wall and other oil production equipments, this adds resistance to oil recovery, have impact on the speed of oil pumping, reduces oil pumping amount.
The utility model patent public affairs that authorized announcement date is on January 4th, 2017, Authorization Notice No. is CN205858280U
A kind of paraffin removal from oil well instrument is driven, which includes base, and base includes upper and lower two flanges, and base is equipped with
Wax removal structure between upper and lower two flanges, wax removal structure include two wax removal knives, and the cross section of wax removal knife is semi arch
Shape.Wax removal knife is fixed therein on a flange, and by opening up slot hole on corresponding flange, can adjust wax removal knife with
The distance between casing tube outer circumferential surface, finds the optimum position between casing tube and wax removal knife, then will by screw bolt and nut
Wax removal knife is fixed on corresponding flange, so as to ensure wax removal knife and the matching degree and closeness of contact on the outside of casing tube.
But a wax removal structure is only provided with above-mentioned paraffin removal tool, it can be adjusted by the position for adjusting wax removal knife
The single of wax removal knife scrapes wax thickness, when clearing up the product wax on casing tube or other structures outside, if the thickness is larger,
Then the resistance in paraffin cutting suffered by wax removal knife is very big, and wax removal knife is fragile and paraffin cutting effect is poor;If the thickness is smaller, paraffin cutting
Effect unobvious, to reach more preferably paraffin cutting effect, can only carry out multiple paraffin cutting, cause the reduction of paraffin cutting efficiency.
