Description

Technical Field

[0001] The utility model relates to the technical field of oil field collection, in particular to a drilling fracturing device for increasing oil field production. Background Art

[0002] In the process of oil extraction, it is not just extraction in a certain direction, but multiple circumferential directions. That is, as the degree of extraction increases, after all the crude oil in the old fracture control area has been extracted, it is necessary to implement temporary plugging and redirection repeated fracturing to open new layers in the longitudinal and horizontal directions to extract crude oil outside the old fracture control area. Most of the existing oil field production increase drilling and fracturing devices are connected by pipelines, and the filter net is fixedly connected inside the pipeline. Since the filter net is inside the fixed connection pipeline, the temporary plugging agent particles will adhere to the filter net after long-term use, thereby blocking the filter net, which is not easy for the staff to clean, affecting the temporary plugging agent to open new cracks and redirect the cracks, and affecting the extraction of the oil well.

[0003] For example, the publication number CN202022011201.5 discloses "A Type of Oilfield Production Increasing Drilling Fracturing Device". When the filter net is blocked by a temporary plugging agent, the internal thread and the external thread are threadedly connected. By rotating the frame, the frame can be removed from the fixed groove of the connecting plate and the filter net can be replaced, which can easily ensure the fracturing effect of the fracturing device.

[0004] However, the above-mentioned disassembly of the filter is relatively troublesome and needs to be removed from the head. When the composite pipeline is too long, the filter cannot be replaced, which will still cause the temporary blocking agent to become blocked and affect the use of the pipeline.
