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。

Abstract: 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 naturalwell 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.

Key words: complicate oil and gas reservoirs, extremelylow permeability reservoirs, effective fracturing cut-off values
