摘　　要：针对新疆油田乌33井区极强水敏储层改造的需要,研究应用了复合原油压裂技术。将不同粘度原油调配,通过添加降阻剂降低原油摩阻,形成大排量注入和携砂的原油压裂液。根据油基压裂现场作业风险及安全要求,形成了包括安全消防要求等在内的复合原油压裂施工工艺。现场实施20多井次,压裂效果明显。A mixed crude fracturing technique has been developed to meet the needs of stimulating the extra high water-sensitivity reservoir in Wu33 wellblock of Xinjiang Oilfield. The crude oil fracturing fluid with ability of carrying sand and injecting in a large number of volume is formed by configuring various viscosities at a given rate, and adding friction reducer to low crude oil friction. Based on the requirements of risk and safety for the large field operation of oil-base fracturing, a field operation procedure for the crude oil fracturing has systematically been worked out. By approximate 20 field applications, the effects have been obviously.
