边底水油藏是长庆油田陇东油区内一个重要的油藏类型 (开发区块有 12个 ,动用地质储量 2 5 97×10 4 t,占全厂含油面积的 17 3% ) ,存在着油层物性好、压力系数偏低 ,油层易受到伤害的特点 ,尤其是其储层地质条件的局限性 ,给其开发过程中增产措施的选择带来一定困难。近几年通过在具代表性的华池油田、元城油田的开发实践中的不断研究、试验、探索 ,逐渐形成了一套较为成熟的工艺技术
The edge water reservoirs are an important reservoir type in Longdong Oilfield of Changqing Oilfield (there are 12 development blocks with a usable geological reserve of 2597 × 104t, accounting for 17.3% of the total oil area of the whole plant) It has the characteristics of good reservoir property, low pressure coefficient and easy damage to the reservoir. Especially the limitation of its reservoir geological conditions brings some difficulties to the choice of stimulation measures in the development process. In recent years, through the continuous research, experimentation and exploration in the development practice of the representative Huachi oilfield and the Yuancheng oilfield, a set of relatively mature process technology has been gradually formed
