适用于目前北海大多数油井的设备如套管、钻柱、泥浆处理系统、测井系统和钻机等在用于北海中央地堑高温高压井（以下简称HPHT井）的钻井时都将需要改进。在北海中央地堑HPHT钻井的数据正在缓慢地增加，以前，这类井主要钻在英国领海内，1991年挪威的领海内规划中的这类钻井数量也有所增加。 Suitable for use in most wells in the North Sea today, such as casing, drill string, mud treatment systems, logging systems and drilling rigs will need to be improved in drilling for HPHT wells in the North Central Central Rift (HPHT wells). Data on HPHT drilling in the North Sea Central Graben are slowly increasing, as they have mainly been drilled in British territorial waters before, and the number of such wells in Norway’s territorial waters planted in 1991 has also increased.
