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 2 4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。
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.
