复杂岩性油藏酸压技术在青海油田的试验应用

EXPERIMENTAL APPLICATION OF ACID FRACTURING TECHNOLOGY FOR THE COMPLEX LITHOLOGY RESERVOIR IN QING HAI OILFIELD

    摘要
  • 摘要: 青海油田众多勘探开发区域的储层均属于复杂岩性油藏,采用单纯的砂岩酸化或碳酸盐岩储层酸压技术均有很多缺陷。为此,使用针对复杂岩性油藏开发的"稠化酸深度酸压+多组分酸闭合裂缝酸化"组合技术,在狮24斜井、跃灰4井等进行了先导性试验,取得了显著的改造效果。

     

    Abstract: All of the formation of the numerous reconnoitre exploitation the district in Qinghai Oilfield belong to the Complex Lithology reservoir.Many faults exist in the acidizing of sandstone or acid-fracturing technique of carbonate rock formation.For this, the usage aim at the complex lithology reservoir establishment of combined technology of "Gelled acid acid-fracturing + poly-component closed fracture acid is developed".Leading experiment in Shi24 well and Yuehui-4 well, and obtain best effect.
