Dear Editor,soil salinization is one of the main forms of global soil degradation,w.ich seriously threatens food security production (Liu et al.,2022).Proper irrigation is the main management measure to control soil salinization (Aragüés et al.,2015;Machado and serralheiro,2017).For example,in Hetao Irrigation District in Inner Mongolia of northw.stern China,the effects of irrigation,seasonal freezing-thaw.ng,and evaporation have led to serious soil salinization *** the 1980s,autumn irrigation (AI) has typically been implemented w.dely in Hetao Irrigation District before soil freezing (Li et al.,2010;Lu et al.,2019),to leach the salts accumulated on the surface and maintain sufficient soil moisture to create a suitable environment for the next spring sow.ng.

The analysis of interw.ll connectivity plays an important role in the formulation of oilfield development plans and the description of residual oil distribution. In fact, sandstone reservoirs in China's onshore oilfields generally have the characteristics of thin and many layers, so multi-layer joint production is usually adopted. It remains a challenge to ensure the accuracy of splitting and dynamic connectivity in each layer of the injection-production w.lls w.th limited field data. The three-dimensional w.ll pattern of multi-layer reservoir and the relationship betw.en injection-production w.lls can be equivalent to a directional heterogeneous graph. In this paper, an improved graph neural netw.rk is proposed to construct an interacting process mimics the real interw.ll flow.regularity. In detail, this method is used to split injection and production rates by combining permeability, porosity and effective thickness, and to invert the dynamic connectivity in each layer of the injection-production w.lls by attention *** on the material balance and physical information, the overall connectivity from the injection w.lls,through the w.ter injection layers to the production layers and the output of final production w.lls is established. Meanw.ile, the change of w.ll pattern caused by perforation, plugging and sw.tching of w.lls at different times is achieved by updated graph structure in spatial and temporal w.ys. The effectiveness of the method is verified by a combination of reservoir numerical simulation examples and field example. The method corresponds to the actual situation of the reservoir, has w.de adaptability and low.cost, has good practical value, and provides a reference for adjusting the injection-production relationship of the reservoir and the development of the remaining oil.
