:对胜利油区的稠油资源进行分类评价 ,指出胜利油区稠油油藏类型的复杂多样性 ;在分析该区稠油注蒸汽热采开发形势的基础上 ,认为稠油热采所暴露的主要矛盾是 :已开发区块基本进入高轮次吞吐阶段 ,面临如何确定下步开发方式及提高采收率问题 ;而尚未开发的新区大多属于超稠油、低渗、薄层或深层等开采难度较大的低品位油藏。为改善稠油油藏的热采效果 ,进一步提高采收率 ,油藏工程及数值模拟研究表明 :对老区不适合转驱的油田 ,通过综合治理、新技术应用 ,可以改善开发效果 ;理论研究及现场工业开发实践表明 ,乐安油田具有汽驱的可行性 ;利用水平井可有效开采超稠油。通过上述开发对策的实施 ,预计胜利油区稠油增加可采储量 96 0× 10 4 t,使该区稠油步入经济合理的开发轨道。
: The classification and assessment of heavy oil resources in Shengli Oilfield are carried out to point out the complex diversity of heavy oil reservoirs in Shengli Oilfield. Based on the analysis of the development situation of thermal recovery of heavy oil steam injection in this area, it is considered that heavy oil thermal recovery is exposed The main contradiction is that the developed blocks have basically entered the stage of high rounds of throughput and are faced with the problem of how to determine the next step of development and enhance the recovery rate. Most of the untapped new areas belong to super-heavy oil, low permeability, thin or deep layers Exploitation of difficult low-grade oil reservoir. In order to improve the thermal recovery effect of heavy oil reservoirs and to further enhance oil recovery, the reservoir engineering and numerical simulation studies show that the development effect can be improved through the comprehensive management and application of new technologies in oilfields that are not suitable for drive-displacement in old areas. And field industrial development practice shows that the gas field flooding feasibility of Lean; the use of horizontal wells can effectively super-heavy oil. Through the implementation of the above development measures, heavy oil in Shengli Oilfield is expected to increase recoverable reserves of 96 0 × 10 4 t so that the heavy oil in this area will enter an economic and reasonable development track.
