Adjustment Countermeasure And DU 48 Hard Recoverable Reserves Of Secondary Development

Du 48 located in a northern district of Shu,the sand layer is developed to four Dujiatai,from top to bottom is divided into 0 Du,Du Ⅰ,Ⅱ Du,Du Ⅲ oil four groups,10 sandstone,30 small layer bearing area 3.5km2,the effective thickness of 31.02 m,inplace1689×104t,the typical-thin interbedded heavy oil.The block 1987 production date is on Liaohe Oilfield crude oil production contributed greatly in recent years,high-cycle oil well production,formation pressure decreases rapidly reduce oil production rate,the block has entered the thermal recovery later development,development costs continue to increase.To improve the producing degree of heavy oil reserves portrait old block of Du Du 48 0 reservoir in the secondary development of countermeasures carried out adjustments.This paper aims through the application of three-dimensional seismic,logging a secondary means of re-understanding of reservoir group 0 Du,Du 0 reservoir in construction,fine fine reservoir characterization studies.DU by test mining evaluation 0 Formation reservoir potential,to determine the reservoir potential,combined with the characteristics of the reservoir,re-planning development well,the old form of heavy oil well network throughput late reconstruction technique using the "layered development" concept,Du group0 low resistance reserves embodiment stratified horizontal wells(oil layer 5)development north side by the linear expansion rolling development wells.
