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

In recent years ,with the further development of the oil field, the rising water content, the difficulty with the interpretation of the development well of YingTai, and logging interpretation cannot meet the reservoir evaluation's need any more. In order to overcome these difficulties, we apply some new techniques and some new theories. Such as using thermal spectrometry, gas chromatographic and fluorescence microscopic image technique to establish the identification method of H,S,P,G of the oil and water layer .We can distinguish the high resistant water layer, the lower resistant oil layer and poor oil layer, and can provide reference to completion method and preparing reasonable production testing scheme by using thermal spectrometry and gas chromatographic. We can forecast the fluid properties before running casing, and can decide whether run casing or not, the more important is that we can save the cost of the formation testing and water shutoff in the later stage, for this purpose of improving the hit rate of drilling is most instuctive.Furthermore, how to acquire the parameter of So is the most important for the reasonable development program, caiculating exploitable reserve, and forecasting the reservoir productivity.
