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

Su 11 blocks under the background of alluvial river depositional system, reservoir with deep burial, poor physical properties, strong non-heterogeneity, single well with small reserves, low yield, pressure drop, the characteristics of stable production capacity is poor, the blocks were development effect evaluation control, for reasonable development of block to provide technical guidance, to ensure the efficient development of the block.This study makes full use of the gas reservoir dynamic and static data, takes gas wells in this area into static and dynamic classification. Analyse all kinds of gas well production performance and development situation; using gas reservoir engineering method, make in-depth study of the rationality of wells, rational productivity of single well, gas well dynamic reserves, recovery factor prediction and the law of diminishing. The results of research show that the reasonable yield of single well in this block is 1.5×104m3/d, 600×600m irregular diamond well net is reasonable, and the law of diminishing law belongs to the exponential decline, which has a long period of production. The actual production results show that the main development index of the Su 11 block is higher than that of the development plan, and it is better than the other blocks in the region, which has achieved good economic benefits and social benefits.
