Research On Development Technology Of Horizontal Well In Buried Hill Fractured Reservoir

Sudeerte region Budate reservoir is a metamorphic rocks buried hill fractured reservoir, the reservoir have complex lithology,complex media types and poor physical characteristics of crude oil.The reservoir has certain natural energy,but energy is limited,and most wells have lower natural productivity,in order to achieve the efficient exploitation of such reservoirs, fracturing stimulation measures need to be taken,unconventional technology development can be considered.According to sudeerte oilfield geological characteristics and development traits,adaptive assessment for horizontal wells is to be taken.Horizontal development of the appropriate blocks are screened in buried hill fractured reservoir.Based on theses blocks,numerical reservoir and reservoir engineering studies of the combination of means are used,in order to study productivity evaluation of a fractured buried hill reservoir and analysis its influencing factors.Based on this numerical simulation model,numerical simulation for horizontal wells is to be taken in budate buried hill fractured reservoir.Reasonable production forecast method, development guide line forecast and economy benefit assessment are developed.Basd on present development actuality of reservoir,reasonable well density and oil rate are optimized in different blocks of sudeerte,technology limits for horizontal well of buried hill fractured reservoir are established.The above results will instruct that horizontal well develops budate buried hill fractured reservoir,improve this kind reservoir's develop effect,advance its not employed reserves and instruct other reservoir's exploitation have also great significance.
