海上油田水平井控水完井技术现状及发展趋势

Status and Development Trend of Horizontal Well Water-control Completion Technology for Offshore Oil Field

水平井开发技术已在底水油藏、薄层油藏及低渗透油气藏的开发中得到了广泛的应用。但是,在油田实际生产过程中,水平井见水快、含水率高是一个普遍性的问题。介绍了海上油田出水现状、出水机理以及常用的中心管控水、ICD控水、AICD控水等几种控水技术。根据海上油田开发趋势,智能完井控水技术是未来主要的发展方向,具有很大的开发价值。

horizontal well technology has been widely used in the development of bottom water reservoirs,thin oil reservoirs and low permeation oil reservoirs.But in the process of oilfield production,the water cut will rise rapidly once water breakthrough occurs in horizontal well,this is a common problem.This article focuses on current situation of offshore oil field water,water production mechanism,the commonly used water control technologies such as ICD,AICD and central tube technology.According to the current development of offshore oil field,autonomous Inflow control device is the main direction of development in the future,has great development value.
