Embodiment Construction

[0092] At present, in the field of oil and gas exploitation, the existence of sand plugging can only be confirmed when sand plugging occurs or after sand plugging occurs, and effective early warning cannot be achieved. Therefore, it is difficult to avoid the adverse effects of sand plugging, such as waste of construction materials and mining costs. Elevation, casualties, destruction of formation seepage, scrapping of construction wells, etc.

[0093] Based on the above problems, a method, device and related products for early warning of fracturing sand plugging are provided in the embodiment of the present application. For the need for early warning of sand plugging in the fracturing construction process, the cycle features are extracted from the raw data of each fracturing construction cycle in the process, and matched with the cycle reference features extracted from the historical construction process before sand plugging occurs , and finally warn of sand plugging based on t...

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.
