Abstract
The utility model relates to an accessory for an oil logging instrument, in particular to a pressure-bearing and insulating nipple joint. The pressure-bearing and insulating nipple joint comprises a plug and a socket which are connected with each other, wherein the plug comprises an upper joint and a lower joint; the socket comprises an upper socket connected with the upper joint and a lower socket connected with the lower joint; the lower joint is connected to the upper joint via a press bolt, a sealing gasket, a sealing ring and a circular key; a sealing sleeve is sleeved outside the connecting part between the upper and the lower joints; and a pressure-bearing block is arranged at the connecting part between the lower joint and the lower plug. In the utility model, the pressure-bearing block is additionally arranged between the plug and the socket, so that the sealing property is satisfactory under high temperature and high pressure, oil leaked from one single branch instrument can be effectively prevented from continuously permeating an adjacent instrument, the cost for maintaining the oil logging instrument is reduced, and the service life of the oil logging instrument is prolonged.
Description
Technical field
The utility model relates to a kind of accessory of oil logging tool, especially a kind of insulating short section with pressure-bearing.
Background technology
Insulating short section is the equipment that must join to instrument of bilateral in the well logging, be used for blocking the combination logging bilateral to being electrically connected of Other Instruments shell.It is damaged that the high temperature and high pressure environment of down-hole (extreme case assign 140MPa and 175 ℃) makes certain instrument occur sometimes, causes mud or water and get into instrument internal, until infiltrating into contiguous instrument, causes many instruments of instrument string to be seeped water and destroy.
Existing insulating short section is being tightly connected between the metal joint up and down plug generally; Often ignore being tightly connected between plug and the socket; Sealing performance under HTHP between plug and the socket is bad; Can have influence on the sealing performance of whole insulating short section, continue infiltration to contiguous instrument, increase the apparatus guarantee cost, shorten instrument application life thereby make after single the instrument seepage.
Summary of the invention
The utility model provides a kind of favorable sealing property in order to solve defective and the deficiency that above-mentioned prior art exists, and can effectively prevent after single the instrument seepage to continue to contiguous instrument the insulating short section of the band pressure-bearing of infiltration.
The technical scheme of the utility model: a kind of band pressure-bearing insulating short section; Comprise interconnective plug and socket; Said plug comprises top connection and lower contact, and said socket comprises last socket that is connected with top connection and the following socket that is connected with lower contact, and said lower contact is connected in the top connection through hold-down bolt, sealing mat, sealing ring and round key closely; The outer cover of said top connection and lower contact junction is provided with sealing shroud, and said lower contact is provided with pressure block with following plug junction.
Preferably, said lower contact is connected through following end interface with following plug, and said pressure block is arranged on lower contact and following end interface junction.
The utility model is employed between plug and the socket increases pressure block; Good in HTHP lower seal performance; Can effectively prevent to continue infiltration to contiguous instrument after single the instrument seepage, reduce the maintenance cost of oil logging tool, prolong the application life of oil logging tool.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1. top connections among the figure, socket is 3. gone up in 2. lower contact, 4. plays socket, 5. sealing mat, 6. round key, 7. sealing ring, 8. hold-down bolt, 9. pressure block, 10. sealing shroud, 11. times end interfaces.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
As shown in Figure 1; A kind of band pressure-bearing insulating short section; Comprise interconnective plug and socket, plug comprises top connection 1 and lower contact 2, and socket comprises last socket 3 that is connected with top connection 1 and the following socket 4 that is connected with lower contact 2; Lower contact 2 is connected in the top connection 1 through hold-down bolt 8, sealing mat 5, sealing ring 7 and round key 6 closely; The outer cover of top connection 1 and lower contact 2 junctions is provided with sealing shroud 10, and lower contact 2 is connected through following end interface 11 with following plug 4, and following end interface 11 is provided with pressure block 9 with lower contact 2 junctions.
The utility model is employed between plug and the socket increases pressure block; Good in HTHP lower seal performance; Can effectively prevent to continue infiltration to contiguous instrument after single the instrument seepage, reduce the maintenance cost of oil logging tool, prolong the application life of oil logging tool.
Claims (2)
1. be with the pressure-bearing insulating short section for one kind; Comprise interconnective plug and socket; Said plug comprises top connection and lower contact, and said socket comprises last socket that is connected with top connection and the following socket that is connected with lower contact, and it is characterized in that: said lower contact is connected in the top connection through hold-down bolt, sealing mat, sealing ring and round key closely; The outer cover of said top connection and lower contact junction is provided with sealing shroud, and said lower contact is provided with pressure block with following plug junction.
