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

The major contradictions gradually appear and the situation of keeping production capacity is very toughe with prolongation of waterflooding time.Thus we study fine reservoir valuation and waterflooding technology strategy of black 46 in Daqingzijing oilfield as the great subject.The article studys the structural characteristic, geologycal characteristic, distribution of sandstone, regularities of fluid`s distribution of black 46 `s pay zone in depth in Daqingzijing oilfield, Analyses the control of water drive and producing degree and their influencing factor, evaluates block`s development effect objectively by studying sedimentology, petroleum geology, structural geology, reservoir engineering method, log interpretation theory as guidance and start with the cause mode of reservoir. Core analysis, and using the information of well logging, well sinking,production and many kinds of tests. We study the influenced degree of remaining oil and watered-out by revervoir constituent influence, set up mode ofremaining oil and watered-out by restricting of revervoir constituent provide good technological means on forecasting remaining oil, deepen the knowledge on the regularities of remaining oil`s distribution. And finally summarize the technology and countermeasure of fine water drive, and under its direction, we carry out measures, such as regulating and controlling on fine water injection, fine stratified waterflooding, improving flooding well network etc.Improve development effect.
