在塔中 4油田低洼地带可采用水平浅埋加降阻剂的方式布设接地装置。降阻剂的合理用量为 12 5kg/m ;当要求R≤ 10Ω时 ,可采用一只高硅铸铁金属电极 ,埋深2 5m ;当要求R≤ 5Ω时 ,采用两只并联使用即可。在沙丘地带 ,当要求R≤ 10Ω时 ,可采用一只高硅铸铁深井埋设深 30m ;当要求R≤ 5Ω时 ,在同一个深井 ,可采用两只高硅铸铁金属电极并联使用 ,埋深分别为2 6m和 30m。
In Tazhong 4 oilfield low-lying areas can be shallow horizontal and ground with Jiang Zuji way laying grounding device. Reasonable dosage of Jiang Zuji is 12 5kg / m; when R ≤ 10Ω, a high silicon cast iron metal electrode can be used with a depth of 25m; when R ≤ 5Ω, two parallel connections can be used. In the sand dune area, when R≤10Ω, a high silicon cast iron deep well can be buried for 30m deep. When R≤5Ω, two high silicon cast iron metal electrodes can be used in parallel in the same deep well. For 2 6m and 30m.
