The present invention relates to a filter stack, which comprises: a stack body, which is a circular ring-shaped sheet; a primary filter convex portion and a secondary filter convex portion arranged on the upper surface of the stack body, wherein the primary filter convex portion and the secondary filter convex portion are arranged radially from the outside to the inside and spaced apart; a primary filter groove portion and a secondary filter groove portion are arranged on the lower surface of the stack body, wherein the primary filter groove portion and the secondary filter groove portion are arranged radially from the outside to the inside and spaced apart; the positions of the primary filter groove portion and the secondary filter groove portion correspond to the positions of the primary filter convex portion and the secondary filter convex portion on the upper surface of the stack body, respectively. The present invention also relates to a stacked filter, which comprises a plurality of filter stacks stacked together in an aligned manner. The filter stack and stacked filter of the present invention realize double-stage filtration, have a simple structure, good filtering effect, and high filtering efficiency.

This invention discloses a nodal-type well-induced polarization field observation device and method. By setting up a downhole data acquisition device and a ground receiver, the downhole data acquisition device includes a data transmission module, a multi-node acquisition unit, and a counterweight. The multi-node acquisition unit includes multiple node acquisition modules and multiple connection modules. The modular design enables digital transmission of downhole signals, avoiding signal coupling caused by long cables in traditional well-induced polarization observation. Through the nodal observation method and flexible connection modules, the large electrode potential gradient measurement requirement specified in the well-induced polarization law is achieved in small-diameter boreholes, increasing the useful signal strength. The nodal design of the transmission section allows for arbitrary replacement of the number of node acquisition modules, improving data acquisition efficiency, and also allows for arbitrary replacement of the node sampling units, greatly improving the applicability of the well-induced polarization field observation device.
