Fine Adjustment And Potential Method Study On The West Of B1 Fault Of Gaotaizi Reservoir In High Water Cut Period

Aiming at the contradictions in how to control the mining blocks,block the natural decline,the actual water cut rising fast,how to better tap the potential of remaining oil,and prolong the stable production of block,improve the comprehensive development benefit,for adjusting method effectively is an urgent need to answer the problem,through the study of fine adjustment method of high water cut period,to improve the producing degree of reservoir subdivision adjustment,double double for improving water quality of water injection reservoir,fracturing producing remaining oil fault zone,well spacing flooding wells up blocking water control methods are analyzed and summarized.Study the Gaotaizi reservoir subdivision adjustment combination principle,subdivision,subdivision adjustment technology;summarized a set of suitable for Multi-layer Reservoir injection well segmentation criteria.Through the measurement of water injection zone starting pressure,measured by qualitative research,fine water injection manage mentrestructuring verdict;to starting pressure gradient layer based,single pressure lifting,make adjustments layers corresponding measures of oil and water wells,summarizes the injection production regulation.Combined with fine adjustment,improve water quality,to achieve precise injection.To carry out the fault zone and the effect of remaining oil tapping technology research;on the basis of fault structure,deep structure and reservoir top oil well sand fine results,optimized design of fracturing well,improve the recovery of residual oil.The well spacing of additional blocking water wells tapping and understanding.Through research,summed up a set of Gaotaizi reservoir fine potential tapping and efficient development adjustment technology model,provide a reference for the future development of fine adjustment work.
