Abstract：Jizhong marlstone tight oil reservoir lithology is special, with abnormal high ground stress, there is no domestic and overseas field experience used for reference in similar reservoir horizontal well transformation up to now. Conducted is analytical investigation on petrologic features, physical properties and acid etching in Shulu Marlstone-conglomerate Tight Oil Reservoir and developed are a combined transformation process of "acid fracturing and sand mixture" and associated acid formulation system. Practical field application results in such two horizontal wells as Shu-Exploration lH and 2x show that technical process can reduce Construction risk and increase crack communication volume and flow conductivity and the purpose of high and stable production after transformation can be reached. The technical process has important technical contribution in Jizhong marlstone tight oil reservoir development.
