管材是鑽探施工中的主要劳动手段,目前全局在庫在用管材总值,約佔全部器材的25％;管材攤銷额約佔鑽探成本的5～6％,如果它的阶差不正常,亦往往影响流动資金週轉和成本升降的不正常。自1956年起鑽探管材改作低值及易耗品管理,管材的价差問题就显得更为突出。东北分局針对这个問题进行了一次比較深入的調查研究,他們搜集了1953年以来的历史資料,根据逐年管材的帳面价格与1956年計划价格做了較詳細的分析,对于目前管材价差过大問題有了一个初步解答。鑑于这个
Pipe is the main means of drilling construction work, the current global value of the total pipe in use, accounting for about 25% of all equipment; pipe amortization accounts for about 5 ~ 6% of drilling costs, if it is not normal level, also Often affect the liquidity turnover and costs rise and fall is not normal. Since 1956 drilling pipe changed to low value and consumables management, the problem of pipe spread becomes more prominent. Northeast Branch of the issue for a more in-depth investigation and research, they collected historical data since 1953, according to the book price of pipe and 1956 annual plan price made a more detailed analysis of the current pipe spreads too large Have a preliminary answer. Given this
