The invention provides a fracturing
pipe column and a fracturing method. The fracturing
pipe column comprises an oil
pipe, a hydraulic anchor, a first packer, a
differential pressure sliding sleeve and a second packer which are sequentially connected from top to bottom. The
differential pressure sliding sleeve comprises a
sand blasting cylinder, a connecting cylinder and a sliding sleeve. The connecting cylinder is fixedly connected to the upper end of the
sand blasting cylinder; the sliding sleeve is arranged in the
sand blasting cylinder, the outer wall of the sliding sleeve is provided with an outer circular bead, the outer circular bead is located below a cylinder body connecting part, a
liquid storage cavity is formed between the outer circular bead and the cylinder body connecting part, and the side wall of the sand blasting cylinder is provided with a liquid outlet communicated with the
liquid storage cavity; a bearing
conical surface for bearing a ball is arranged on the inner wall of the sliding sleeve, and the bearing
conical surface can be expanded outwards under the action of set thrust applied by the ball; a first clamping groove and a second clamping groove which are sequentially distributed up and down are formed in the connecting cylinder, and the sliding sleeve is provided with a spring claw. By means of the fracturing pipe column and the fracturing method, the technical problems that in the prior art, the fracturing pipe column dragged through the oil pipe is adopted, liquid in a well needs to be discharged after one layer is fractured, construction is interrupted, the
workload is increased, and the fracturing effect is affected are solved.
