摘　　要：安棚油田碎屑岩储层属扇三角洲沉积,储层埋藏深,胶结致密,具有特低孔特低渗储层特征;油气藏类型复杂,有普通黑油油藏、挥发油藏和凝析气藏等。通过综合应用Hobson法、产能法、浮力法等得到含不同流体储层的下限标准,确定了油层和凝析气层有效压裂的物性下限值,为压裂层位的选取和特低渗油气田的有效开发提供了科学依据。The technology that to determine the cut-off value of extremely low permeability clastic reservoir in Anpeng Oilfield,Biyang Depression,was described.The depositional facies of reservoir is a fan-delta system.The types of oil and gas reservoirs are complicated.There are black-oil reservoir,volatile oil and condensate gas reservoir.The reservoir features are extremely low permeability and low natural well production.Through evaluation study of reservoir,three methods to acquire cut-off value of reservoirs which bearing various fluids was presented,with Hobson method,production ability method and buoyancy method.In the end,the cut-off value for the effective development of extremely low permeability oil and gas field was proposed.
