A method, device and related products for early warning of fracturing sand plugging

Abstract

The application discloses a fracturing sand plugging early warning method, device and related products, which extract cycle characteristics by acquiring raw data of each fracturing construction period during the fracturing construction process. Since the historical construction process is the construction process of sand plugging, the periodic reference features extracted from the original data before sand plugging in the historical construction process reflect the characteristics of fracturing construction before sand plugging. The period characteristics corresponding to the fracturing construction period are matched with the period reference characteristics. When the matching is successful, it can be predicted that sand plugging will also occur in this fracturing construction process. The technical solution provided by this application can effectively determine that the sand plugging problem is about to occur before the sand plugging occurs in the fracturing construction process. Therefore, when the matching is successful, early warning of fracturing sand plugging is carried out, so that construction personnel can take corresponding measures to avoid sand plugging, and avoid or reduce the adverse effects of sand plugging problems.

Description

technical field [0001] The application relates to the technical field of oil and gas exploitation, in particular to a method, device and related products for early warning of fracturing sand plugging. Background technique [0002] In the field of oil and gas exploitation, the construction technology that artificially forms cracks and cracks in the formation through hydraulic action is called fracturing technology. Fracturing can improve the flow environment of oil in the ground, increase the production and recovery of oil wells, and play an important role in improving the flow conditions at the bottom of oil wells. [0003] Fracturing construction usually includes processes such as circulation, pressure test, test squeeze, fracturing, sand addition, replacement squeeze, landscape diffusion pressure and movable string. Due to the complexity of the formation, fracturing operations often face risks and abnormalities. Among various risks and abnormalities, sand plugging belong...

AI Technical Summary

Problems solved by technology

But often when people can judge that the sand plugging problem exists, the sand plugging has already occurred

It can be seen that there is currently a lack of a technical solution that can effectively warn of sand plugging to avoid or reduce the adverse effects of sand plugging.
