1983年一些油田结合本地区勘探、开发区块的地面条件和地下地质构造的特点,积极推广定向井和丛式井钻井工艺。辽河、大港、胜利、中原、华北、江汉和四川等7个油田开展了定向井作业,共完成定向井198口,进尺44.7万米,占全国年进尺的5.63%,是历年来完成定向井最多的一年。完成井平均井深2257米,平均完井周期48天,平均月速度1383米/台月。至1983年底,全国已累计完成定向井533口,累计进尺125.9万米。
In 1983, some oilfields actively promoted the drilling technology of directional and cluster wells in combination with the ground conditions of the exploration and development blocks in the area and the features of underground geological structures. Liaohe, Dagang, Shengli, Central Plains, North China, Jianghan and Sichuan have carried out directional well operations and completed 198 directional wells and footage of 447,000 meters, accounting for 5.63% of the national annual footage, the largest number of directional wells completed over the years Year The average depth of completed wells was 2257 meters with an average completion period of 48 days and an average monthly velocity of 1383 meters per month. By the end of 1983, a total of 533 directional wells had been completed nationwide, with a total footage of 1.259 million meters.
