Because the wellhead pressure of the block is high, the yield is high, the content of hydrogen sulfide in natural gas is 5% -10%, and the dynamic monitoring of the Yuan-Ba gas field is generally tested by adopting a sulfur-proof steel wire transmission electronic pressure gauge; however, in the operation process, sulfur-containing solid matters or impurities produced by the stratum in the well casing are attached to the surface of the steel wire, and in the process of lifting the steel wire, the sulfur-containing solid matters or impurities are accumulated in the steel wire sealing control head, so that the steel wire is easily blocked in the sealing control head. After the steel wire is blocked, the wellhead pressure is high and the hydrogen sulfide content is high in the operation environment, so that the treatment difficulty is high and the risk is high. The phenomenon that the steel wire is blocked due to the accumulation of sulfur-containing solid matters or impurities in the steel wire sealing control head becomes a difficult problem in the operation of the steel wire for testing the sulfur-containing gas well.

Reference numerals: 1-shell, 2-sulfur scraping piece, 3-sulfur scraping groove, 4-discharging tray, 5-positioning piece and 6-discharging groove.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example 1
As shown in figure 1, sulfur device is scraped in operation of super dark high sulphur gas well test wire, scrapes sulfur device fixed mounting and at the sealed control head lower extreme of test wire, scrapes sulfur device and mainly includes: the device comprises a shell, a sulfur scraping piece, a sulfur scraping groove and a discharge tray; the sulfur scraping piece is arranged inside the shell, an internal thread is arranged on the inner surface of one end of the shell, the discharge tray is connected with one end of the shell, which is provided with the internal thread, through the thread, so that the sulfur scraping piece is fixed inside the shell, the sulfur scraping piece is prevented from moving up and down along with the well testing steel wire during the operation of the well testing steel wire, and the effect of scraping impurities cannot be achieved; the other end of the shell is provided with an external thread, and the shell is connected with a sealing control head of the well testing steel wire through the external thread; after scraping sulphur device and using a period, need clear up it, prevent to block up, so, threaded connection is more convenient for install and dismantle and scrape sulphur device.
A sulfur scraping groove is formed in the circumferential surface of the shell; meanwhile, the discharging tray is provided with a discharging groove corresponding to the sulfur scraping groove, and impurities scraped from the well testing steel wire are discharged outside the device, so that blockage in the device is avoided.
The casing, scrape all opened the through-hole in the axial of sulphur piece and emission tray, at the during operation, the test-well steel wire passes whole sulphur device of scraping through the through-hole of each position. Moreover, the diameter of the through hole at each part is not smaller than that of the well testing steel wire, otherwise, the well testing steel wire cannot finish sulfur scraping on the steel wire without penetrating through the sulfur scraping device; meanwhile, the diameter of the through hole cannot be too large, so that the through hole is not beneficial to scraping impurities completely, and the diameter of the through hole is slightly larger than that of the well testing steel wire.
Simultaneously, still include the setting element among the sulphur device of scraping, the setting element sets up the one end of being connected at shell and emission tray for fixed shell and emission tray prevent when the well testing operation, and the tray rotates for the shell, lead to the emission tray to break away from the shell, make and scrape the not hard up sulphur work of deviating from of sulphur piece, can not accomplish the sulphur work of scraping to the well testing steel wire.
Example 2
Preferably, the positioning element is a positioning jackscrew, and the discharge tray is fixed in the circumferential direction by arranging a screw hole on the shell and screwing the jackscrew in.
Example 3
Preferably, the sulfur scraping piece is made of rubber, because the rubber sulfur scraping piece is not easy to generate chemical reaction with substances in the sulfur-gas well, and the rubber sulfur scraping piece is light and convenient and is convenient to install and take out.
Example 4
On the basis of the embodiment 3, preferably, the sulfur scraping piece is a cylinder with a through hole in the axial direction; will scrape sulphur and make into the cylinder, be more convenient for scrape sulphur and put into the shell, scrape the diameter that the ascending through-hole diameter of sulphur piece axial is greater than the test well steel wire slightly, be convenient for scrape the impurity on the test well steel wire.
Example 5
Preferably, a cavity is formed between the end face of the sulfur scraping piece, which is far away from the discharge tray, and the shell, so that the end face of the sulfur scraping piece, which is far away from the discharge tray, is not in full contact with the shell. One end of the sulfur scraping piece is supported by the screwed discharge tray, so that the sulfur scraping piece is prevented from loosening, the end face of the other end of the sulfur scraping piece is not in complete contact with the shell, a partial gap is reserved, and the sulfur scraping piece is prevented from being damaged due to excessive extrusion or excessive pressure. The number of scraping the sulphur piece is decided according to the circumstances, and when the number of scraping the sulphur piece was greater than 1, every two liang of sulphur pieces of scraping do not contact completely, but through setting up a plurality of little archs on scraping the sulphur piece, make and remain some clearances between it, prevent that pressure is too big, lead to scraping the sulphur piece and being extruded together and cause the damage.
Example 6
Preferably, when the number of the sulfur scraping grooves is even, the sulfur scraping grooves are symmetrical pairwise on the circumferential surface of the shell; the sulfur scraping grooves which are symmetrical mutually are more convenient for discharging the scraped impurities. In general, the number of the sulfur scraping grooves is 2 or 4; when the number of the sulfur scraping grooves is 2, the 2 sulfur scraping grooves are mutually symmetrical on the shell; when the number of scraping sulphur groove is 4, every 2 scrape sulphur groove symmetry settings on the shell each other, and every scrapes sulphur groove and mutually becomes 90 degrees right angles in the footpath of shell, simultaneously, discharge the groove number of discharging on the tray and scrape sulphur groove number the same, and the position one-to-one.
Example 7
Preferably, the through hole of the contact surface of the sealing control head of the casing and the well testing steel wire is in a horn shape, so that the well testing steel wire is prevented from being damaged by friction on the contact surface. Normally, the contact surface and the through hole are at a right angle of 90 degrees, and the two are mutually hammered, so that after the casing is connected with the sealing control head of the well testing steel wire through threads, if the connection is not tight or a gap exists, the well testing steel wire is easy to rub against the end surface of the contact surface, and therefore, the through hole on the contact surface of the casing is arranged in a horn shape, namely, forms a certain angle with the horizontal direction, such as 45 degrees, and the abrasion of the well testing steel wire can be effectively prevented.
When the device is used, the shell is firstly installed at the lower end of a sealing control head of a well testing steel wire (through threaded connection), the sulfur scraping piece is placed in the shell, then the discharging tray is connected with the shell (positive thread), the sulfur scraping piece is fixed, sulfur-containing solid matters or shaft impurities scraped from the steel wire are discharged from the discharging groove of the discharging tray, and then the sulfur-containing solid matters or the shaft impurities are discharged out of the device through the sulfur scraping groove. The discharging tray and the shell are positioned by the positioning jackscrew, so that the tray is prevented from rotating. And finally, the steel wire penetrates through the whole sulfur scraping device, so that the structure is simple and the operation is convenient.
