摘　　要：方法利用高砂比压裂技术，开发双河低渗透油田。目的改善裂缝导流能力，提高产量。结果高砂比压裂技术在双河油田应用后，使整个区块日产量达２５０ｔ，是措施前常规压裂的５倍。结论利用高砂比压裂技术可造出具有高导流能力的宽、短裂缝，是目前改造低渗透油层的有效措施。Method\ Fracturing with high sand content is used to develop Shuanghe low permeability oil field. Purpose\ To achieve better conductivity and improve production. Result\ Adopting this technique, the whole block produces 5 times as much oil as conventional fracturing, i.e. 250t/d. Conclusion\ This technique, which produces wide and short fractures of high conductivity, is an effective measure for upgrading low permeability oil bearing formation, but steps must be taken to perfect its complementary technique.\;
