陕北LFP油田注水开发效果分析

鄂尔多斯盆地LFP区块中生代油藏油气资源较丰富,在低孔、低渗的前提下为提高采收率采用了注水开发技术。本文对该区各主要层段的注水开发应用状态及效果进行了分析,同时从勘探成果与开发资料进行对比分析的角度针对各层的特点提出了相应的调整建议。本文是用勘探与开发资料进行综合分析的一个探索。

Waterflooding effect analysis of the LFP oilfield in the northern part of Shaanxi

The LFP oilfield in the Ordos basin is rich in oil and gas,under the premise of low porosity and low permeability reservoir,waterflooding technique has adopted to improve the extraction percentage.We analyze waterflooding technique applications and effects in the main layers of this field,meanwhile,make contrastive analysis between exploration achievements and exploitation materials to Chang1 layer,thus to put forward corresponding suggestions of these layers to improve the extraction percentage in this oil field.This article is an exploration for comprehensive analysis by combinating exploration achievements and exploitation materials.
