Research On The Control System Of Oil Extraction Joint Station Based On PLC

Deep heavy oil in lukeqin oilfield with hollow sucker Rod pump mixing light onviscosity reduction and lifting technology, Serious on the sand blocks, There is a high failurerate and maintenance problems of short duration, high maintenance costs, Taking into accountdepth of sucker Rod pumping pump and displacement, When40m3/d is production volumedid not adapt to the underground and surface facilities of parameters. This article in theconcrete analysis of hollow sucker Rod lifting technology of mixing light limit and the actualsituation at the scene, made a deep heavy oil prop-screw pump oil production technology.Physical characteristics of deep heavy oil in lukeqin oilfield choose France as PCM120TP2600screw pump stator rubber of down-hole pumps and matching159models, Use ф29mmHL sucker Rod as a drive rod, screw pump depth down to2000m below for the firsttime.Complete with Y211-148Packer for core-doped thin tools, implements the annulusblending light viscosity-reducing technology. Ground using variable frequency control deviceto realize yields linear control, a variety of online monitoring of production parameters,ensuring the dynamic analysis of screw pump production. Small second annulus cycle washwell, effective in improving single well production rate, extend oil maintenance-free period.By the end of2009, the cumulative workload completed5well, success rate of construction100%, effective rate100%,16.4m3/d increasing liquid, increasing average single-well oil3.36t/d. Achieved significant economic results.
