Fracturing sand blockage early warning method and device and related products

Abstract

The invention discloses a fracturing sand blockage early warning method and device and a related product. The method comprises the steps that original data of each fracturing construction period in the fracturing construction process are acquired to extract period features; a historical construction process is a construction process in which sand blockage occurs, periodic reference features extracted from original data before sand blockage in a historical construction process reflect features of fracturing construction before sand blockage; therefore, the period characteristics corresponding to the fracturing construction periods in the fracturing construction process are matched with the period reference characteristics, and when matching succeeds, it can be predicted that sand blocking will happen in the fracturing construction process. According to the technical scheme provided by the invention, the sand blockage problem can be effectively judged to be about to occur before sand blockage occurs in the fracturing construction process. Therefore, fracturing sand blockage early warning is carried out when matching succeeds, constructors can conveniently take corresponding measuresto avoid sand blockage, and adverse effects caused by the sand blockage problem are avoided or reduced.

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.
