ATTENTION: K10 GAUGES BOTH STRAIN AND QUARTZ OF ALL SIZES: DURING ASSEMBLE/ DISASSEMBLE, WRENCHES ARE TO BE PLACED ON THE CLOSEST FLATS. NO PIPE WRENCHES ARE TO BE USED ON KUSTER MEMORY GAUGES. WISES WITH ROUND HALF CLAMPS ARE RECOMMENDED FOR FIXING THE GAUGES FOR DISASSEMBLE PROCEDURES. IN ORDER TO AVOID TOOL MALFUNCTIONING, O’RINGS UNDER THE ELECTRONICS HOUSING SHOULD BE REPLACED STRICTLY ACCORDING THE PROCEDURE, DESCRIBED AT THE END OF THIS MANUAL.
10. Drop some oil into the transducer sub until it’s full. Never insert syringe or any other device into the transducer port more than 1/8”, as damage to transducer may occur. 11. Using oil pump, fill buffer tube assembly with a light mineral oil. Don’t try too hard pushing the pump lever. Slow, but steady force until oil flows from the end of the tube, that’s all you need. 12. Install buffer tube assembly on the gauge. 13. Install tandem sub on the gauge with external RTD.
9. Connect gauge through comm. box to the computer, wait for 4 (strain gauge), and 5 (quartz gauge) LED flashes on comm. box and download data to the hard drive (See software operational manual). CAUTION: DO NOT DISCONNECT GAUGE DURING DATA TRANSMISSION. 10. Remove old o’rings from I/O connector side of the gauge. 11. Wipe clean the threads and o’ring surfaces and inspect visually all threads for signs of damage, galling and etc. 12.
6. Replace o’rings on the pressure sub and lube them. 7. Check connector’s o’ring and replace if necessary. Reassembly: 1. Extend telescopic clip through the keyway end of the housing. 2. Grab the connector with the clip. 3. Slide electronic board with connector through the housing, but keep connector below the keyway. 4. With connector below the keyway, screw electronic housing onto pressure sub and tighten it. 5. Pull connector through the keyway. 6. Slide slotted nut over the telescopic clip. 7.
7. Replace o’rings and back-up rings and lubricate them Assemble in the reverse order. DISASSEMBLE/ASSEMBLE K10 QUARTZ 1.5” SOUR SERVICE GAUGE IN ORDER TO CHANGE O’RINGS AND METAL C-RING UNDER ELECTRONIC HOUSING. The frequency of changing O-rings and C-ring under the electronic housing should be dependent on well fluid types, temperature and gauge usage intensity. With high content H2S we recommend changing these O-rings every month or 80 hours in well, whichever comes first.
BATTERY VOLTAGE AND USAGE Given the variety of tests and surveys that exist in the downhole environment, a definitive guideline for battery usage is impossible. The technician needs to use a certain amount of judgment on when to use or not to use a particular battery pack. The decision should be based on three things. 1. The length of the test (survey) to be run. 2. The amount of time a battery has been used. 3. The voltage the battery shows on the communication box.
LITHIUM OXYHALIDE PRIMARY CELLS Basic Handling Note: With the exception of QTC and PC cells, every Electrochem lithium battery is equipped with an internal safety fuse. These very fast acting fuse elements can be opened with even the slightest short circuit. Therefore, use care in handling these products to prevent any potential short circuit condition. If a cell fuse should open, do not attempt to repair it yourself. Contact Electrochem distributor for assistance.
During low rate discharge (5-10 microamps/cm2), the lithium ions that allow the cell to operate can migrate through the passivation layer. As the rate of discharge increases (0.1-1.0 milliamp/cm2), so does the porosity of the passivation layer, allowing greater ion flow and higher power output. This change in the structure of the passivation layer is illustrated in the diagram below. Under normal conditions, the thin passivation layer does not degrade cell performance.
