摘　　要：针对坪北油田部分油水井采用小套管开采“低孔、低渗、低丰、低压、低产”油藏的现实 ,为了节省成本、减少投资 ,实现少投入、多产出的目的 ,特研制了一种小套管井一次多层压裂管柱。 7井次的现场应用表明 ,该管柱具有结构简单、坐封方便、反洗通畅、易解卡。The reservoir of part oil well belong to low porosity,low permeability,low abundance,low pressure and low output in Pingbei oilfield.Using small diameter casing produce the reservoir,its return on investment is low.Reservoir fracturing is indispensable step to improve output.In order to save cost and increase production,a single multiple fracturing string in small cased hole is developed.Through field application in 7 wells,the results show that the string has advantages,such as simple structure,easy setting and unfreezing,single multiple fracturing etc.$$$$
