辽河油田D块难采储量开发技术对策

Technical countermeasures of difficult producible reserves of D Block in Liaohe Oilfield

辽河油田经过40多年的开发,稠油主力区块进入多轮次开发阶段,面临压力下降、油气比下降、老区产量递减较快等多种矛盾。而辽河油田具有丰富的难采储量,加强难采储量评价与开发对辽河油田具有重要意义。本次研究已D兴隆台油层为对象,分析其主要影响因素,通过系列防砂技术、夹层水识别以及地震波形分析技术预测主力砂体范围等技术手段,有效解决了该区难采储量影响因素,为本区难采储量的有效动用提供了技术对策,同时也为辽河油田难采储量的整体开发具有指导和借鉴意义。

After more than 40 years development of Liaohe Oilfield,main heavey oil blocks have been into multi-rounds development and in the face of many contradictions,such as reservoir pressure declines、low gas oil ratio 、rapid decrease and so on.And yet,Liaohe Oilfield has rich difficult producible reserves, which is of great significance of strengthening the development of these reserves.This article takes D block as the study obicet to analyze its main influencing factors,and effectively solves the difficult reserves influencing factors,by using a series of sand control technology,identification of interlayer water,and seismic waveform analysis technique to predict the scope of main sand body,what provides countermeasures to the effective development of of the difficult producible reserves,and has guidance and reference significance to Liaohe Oilfield.
