The Research Of Reservoir Development Regularity To Saling Group In Sabei Area Oilfield Of Daqing

As a part of the oil combination in the central part of Daqing placanticline,Saling Groupis unworking reservoirs Reservoir diagenesis is weak, and Reservoir sensitivity is serious inSabei area oilfield.it is difficult for mining and reconstruction. To explore the feasibility ofgeological reserves producing,Especially the adaptability of well spacing,the miningtechnology reform for the reservoir characteristics and many other aspects of research.so wecan provide technical reserves for Potentialities and enhance in high water cut period.Based on geologic conditions,development stages,development degrees and economicbenefit,the development adjustment modes mainly include well network,well spacing andinjection mode.The quantitative study of sequence stratigraphy and distribution of sandbodyhas been done on the geological features, sedimentary characteristics and reservoircharacteristics using the data of core, laboratory analysis, well logging and seismic, realizedby computer,Analysising remaining oil distribution, identifying a reasonable injector spacingcombine well pattern thickening with water flooding regime adjustment to well patternwithlow control degree,and change5spot injection to inverted9spot water injection to wellpattern with high control degree. So we can determine the best injection pilot area programsscheme through analysising the extendtion of test well network and the potention of the Sayigroup,and design the injector scheme of test area.and predict the development of initialcapacity and development index according to the appropriate injection program.These techniques will ensure the effective development of Daqing peripherialoileilds.The thickness of reservoir of Saling Group are relatively development in Sabei areaoilfield. To explore the feasibility of geological reserves producing, the test of Saling Group ismainly to solve reasonable well spacing, spacing, mining laws and recovery, The results willprovide an effective foundation for exploit Sabei area oilfield.
