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

    Graphical Abstract
    • 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.
