Abstract
An object of the utility model is to provide an oil logging appearance high temperature high pressure insulation nipple joint to overcome the above-mentioned defect that exists among the prior art. Its advantages are high insulating and sealing strength. 2. Can bear 5 tons of pressure, tension and 200 ℃ high temperature. 3. Simple and convenient manufacture and disassembly and strong field maintainability.
Description
The utility model relates to the employed a kind of seal of oil well logging inclination angle instrument.
At present, the insulating short section that oil dipmeter logging instrument is adopted is because its joint and shell are the integral cast structure, dismantles very difficultly, and on-site maintenance is poor; Because the restriction of structure makes its poor sealing performance, insulation effect is low, and especially temperature obviously descends being higher than Celsius 180 insulating properties when spending; The tensile strength that can bear low only about 3 tons; Generally can transmit the signal of 30 cores.
The purpose of this utility model is to provide a kind of oil logging tool HTHP insulating short section, thereby overcomes the above-mentioned defective that exists in the prior art.
Fig. 1. structural representation of the present utility model
Describe the utility model in detail below in conjunction with accompanying drawing. Such as Fig. 1, an end of connector 1 is protruding Platform, its outer wall suit insulator 2 and housing joint 3 are respectively equipped with sealing inside and outside the insulator 2 Circle 4 and sealing ring 5,6; The rear portion of insulator 2 and housing joint 3 is provided with insulator 7 and connects Junctor 8; The inner chamber of connector 1 is provided with high pressure multicore seal head 10, and its two ends arrange respectively multicore Female 9 and multicore public plug 11; Be provided with close between high pressure multicore seal head 10 and the connector 1 Seal 12. Connector 1, housing joint 3 and connector 8 are metal material; Insulator 2 is for poly-Acid imide; Insulator 7 is high temperature resistance and high strength fiberglass; High pressure multicore seal head 10 is 50-60 cores.
Embodiment: by screw thread connector 1 and isolator 2 are coupled together, and have sealing ring 4 to do good sealing guarantee, can prevent that mud from entering the inside of instrument from slit between the two.Between housing joint 3 and the isolator 2 also for being threaded and sealing ring 5,6 seals guarantee; Connector 1 and connector 8 are for being threaded.Because each part of the present utility model is and is threaded, so its integral body can be born the pulling force up to 5 tons.Polyimides as isolator 2 is the insulation materials of high-temperature-resistant high-pressure-resistant, and isolator 7 makes the utility model integral body have to bear 5 tons of pressure and up to the guarantee of 200 degree high temperature.By using high pressure multicore seal head 10 can make the A end pressure is zero, and the pressure of B end is up to 140MP
A, and can realize multicore transmission (50-60 core).
Advantage of the present utility model: the 1. intensity height that insulate and seal. 2. can bear 5 tons pressure, The high temperature of pulling force and 200 degree Celsius. 3. make, dismounting is easy, on-site maintenance is strong.
