塔里木盆地富满油田超深断裂破碎体油藏地质特征与启示
Geological characteristics and implications of ultra-deep fractured breccia reservoirs in Fuman Oilfield,Tarim Basin
摘要
Abstract
The cratonic strike-slip fault zone is an important hydrocarbon accumulation zone in the ultra-deep carbonate rock field of Tarim Basin.At present,the natural energy of the oil reservoirs in the strike-slip fault zone is insufficient,and the decline rate of the oil reserves is fast.It is urgent to deepen the understanding of the geological characteristics of such oil reservoirs,explore new development methods,and investigate countermeasures for enhancing recovery rate.Based on the detailed study of the 12th and 17th fault zones in Fuman Oilfield through comprehensive analysis of outcrops,drilling,seismic surveys,core thin sections,production dynamics,well tests and other data,the types of reservoir space,internal structural characteristics and hydrocarbon accumulation features of the fractured breccia reservoirs are precisely characterized.Appropriate countermeasures for enhancing recovery rate are proposed.The research results indicate:(1)The fractured breccia reservoirs belong to vertical plate-shaped oil reservoirs.The reservoirs develop in the fault core and fracture zone,their reservoir space types are breccia interstitial pores,cavities and structural fractures formed by cataclasis.(2)The ultra-deep fractured breccia reservoirs are initially deposited as tight lithofacies,with very low pre-existing formation porosity and permeability,preserving a low amount of original formation water.There was no significant dissolution of atmospheric water in the later stage,which led to the fractured reservoir bodies having the characteristics of high oil column(up to one thousand meters)and being water-free or having little water content.(3)In terms of geological understanding,detailed description of reservoirs and development methods,three aspects of understanding transformation have been formed:from fault-controlled karst reservoir to fractured breccia reservoir,from description of fault-karst oil reservoir to the internal structure description of fractured breccia oil reservoir,from water injection development to gas injection development.关键词
