摘　　要：低渗致密油藏具有低渗、微裂缝发育、非均质性强等特点。在常规开发技术驱替原油受限制的情况下,利用毛细管力进行油水置换已成为提高致密油藏采收率的重要方法之一。本文主要从致密油藏常规开发技术、渗吸机理、渗吸采油和采用渗吸剂(表面活性剂)采油研究现状以及影响因素等5个方面,总结了常规开发技术的不足和渗吸技术用于开发致密油藏的进展以及未来展望。Low-permeability tight reservoirs are characterized by low permeability,microfracture development and strong inhomogeneity.With conventional development methods to drive off crude oil being limited,oil-water displacement by capillary force has become one of the important methods to improve the recovery efficiency of tight oil reservoirs.This article mainly summarizes the deficiencies of conventional development techniques and the progress and future prospects of using imbibition technology,including conventional development techniques,imbibition mechanisms,imbibition oil recovery,research status of using surfactants as imbibition agents,and influencing factors,in the development of tight oil reservoirs.
