渤海Y油田开发模式总结与开发效果评价

Summary of Development Pattern and Development Effect Evaluation of Bohai Y Oilfield

为了得到针对海上河流相油田的高效、高速开发模式,首先基于渤海Y油田的地质及开发特点,从4个方面论述了该油田的开发模式,分别为精细注水保持地层压力、基于单砂体划分和组合开发层系、依托单砂体井网优化技术调整井网以及提液与控水相结合的综合调整。利用相关油藏工程方法,计算并评价了在渤海Y油田的开发模式下进行生产的各个指标的开发效果,根据单指标计算结果,进行开发效果综合评价。结果表明,渤海Y油田的开发模式适用于大多数海上河流相油田,应用该开发模式能够有效地缩短海上油田的开发年限以及提高油田最终采收率。

In order to effectively and rapidly develop the offshore fluvial faces oilfield, the development pattern of the oilfield is investigated from four aspects which are based on the features of geology and development for Bohai Y oilfield.The four aspects include, fine water injection to maintain formation pressure, combine and divide layer series of development by single sand body, well pattern optimization technology for single sand body and comprehensive adjustment by combining water extraction and water control.Development effects for each single development index developed at the development pattern of Bohai Y oilfield are calculated by reservoir engineering methods.Then the comprehensive development effects are evaluated.Results manifest that, development pattern of Bohai Y oilfield is suitable for most offshore fluvial faces oilfield.The development period can effectively shorten the development period of offshore oil fields and improve the ultimate recovery of oil field by applying this development pattern.
