某矿区钻探施工,自1966年至1973年共完成钻孔102个,进尺二万余米.由于钻孔弯曲的问题,有的影响了储量计算,并造成施工本身的困难,至于因为弯曲过大而使钻孔报废,造成的损失就更大了.为了扭转这种局面,加快矿区勘探速度,我们遵照毛主席关于“要认真总结经验”的教导,从1972年起,对钻孔弯曲原因、规律及防治方法,进行了分析研究,并采取了相应的措施,收到一定的效果.
A drilling operation in a mining area has completed 102 boreholes and a total length of 20,000 meters since 1966 to 1973. Due to the problem of borehole bending, some of the reserves affect the calculation of reserves and cause difficulties in the construction itself. As a result of excessive bending In order to reverse this situation and speed up exploration of mining areas, we follow Chairman Mao’s teaching about “to conscientiously sum up experience ”, since 1972, the drilling of bending Causes, laws and prevention methods, carried out analysis and research, and took corresponding measures to receive a certain effect.
