ORDER STATE.1.3YJ 型机械液压式随钻震击器1YJ 型机械液压式随钻震击器1. 结构及特点结构见右图YJ 型机械液压式随钻震击器是一种机械液压式随钻震击、解卡工具。它集上、下震击作用于一体，可解除钻井作业过程中发生的井下遇阻、遇卡等钻井事故。是打定向井、深井的首选震击工具。2. 工作原理2.1 上击工作原理上提钻具，卡瓦组件受碟簧弹性力及卡瓦机构锁紧力作用，迫使卡瓦锁紧机构抱紧卡瓦心轴。当卡瓦心轴随心轴一起上行克服卡瓦锁

3、紧力以及液压阀总成与延长轴之间的阻尼作用， 震击器将使钻柱储能、 延时， 当心轴上行到解除 约束状态，钻柱中储存的弹性势能转换成向上的动能，产生上击。如需连续上击，则应下放钻具直到锁紧机构重新锁紧， 再重复上述过程，将产生连续上击。2.2 下击工作原理下击机构锁紧器的松开负荷可根据顾客需要改变。上锁紧力和下锁紧力之间有一定比率，并且可调。需下击时， 下放钻具直到压力达到下锁紧力，震击 器将产生下击力。 若需要重复震击，上提钻具到重新锁紧的位置，重复上述过程。3. 使用与操作3.1 下井前的准备3.1.1 经重新装配后的产品，各连接螺纹应按表1 规定紧扣。内腔注满 L HM32 抗磨液压油，震击

4、吨位和锁紧力可根据某口井具体要求调定，并经地面试验合格。3.1.2 下井前震击器处于锁紧状态。3.1.3 钻具配置应使震击器处于钻柱中和点偏上的受位部分。3.1.4 推荐的钻具组合下钻铤（外径不得小于震击器外径 ）+屈性长轴+YJ 型震击器+加重钻杆（外 径不得大于震击器外径）+上部钻心轴二开瓦花键外筒上连接体震击垫卡瓦心轴卡瓦外筒上卡瓦座卡瓦下卡瓦座碟簧调节内套调解外套下连接体延长心轴液压阀总成活塞压力体YJ 型机械液压式随钻震击器23.1.5 当震击器接入立柱后，取下卡箍，并妥善保存。3.2 操作方法3.2.1 下钻时应先开泵循环，再缓慢下放，切忌直通井底造成“人为下击”。若在下钻过程中发

5、生遇卡,可启动震击器实施上击解卡。322 在正常钻进过程中，震击器应处于锁紧位置，在受拉状态下工作。323 发生卡钻事故需上击时，按以下步骤进行: 下放钻具直到指重读数小于震击器以上钻具悬重35 吨（即压到震击器心轴上的力），震击器回到“锁紧”位置。如已为锁紧状态下井的震击力不进行此步骤。进行本步骤操作时，可在井口钻杆上划一刻线，下放一个上击行程可确认震击器回到“锁紧”位置。以拉力 G 上提钻柱，刹住刹把等待震击器释放。上击吨位由上提吨位控制，开始应用较低提拉顿位, 以后逐渐增加顿位，在同一上提顿位上应多次震击以加强作用效果。最大上提吨位决不允许超过震击器以上 钻柱重量与震击器最大上击释放吨位

6、之和。再重复上述过程，将产生连续上击。在不同钻头水力压降的情况 下，震击器最大上击释放吨位是不同的，震击器最大上击释放吨位应按不同钻头水力压降分别确定。G=震击器上部钻柱重量+震击器上击释放吨位3.2.4 当发生卡钻事故需下击时，按以下步骤进行: 以压力 G 下压钻具产生震击。G =地面调定的下击吨位 +泥浆阻力+摩擦阻力+指重表误差继续向下震击。震击器下击回位时，上提钻柱时间不能过长，避免产生不必要的上击。4.现场保养及维修4.1 现场保养使用时间短或中等程度震击，而震击次数少的情况下，可在钻台现场进行。在井场钻台上起出井后，冲 洗震击器外表面、水眼的泥浆，冲洗油堵部位。清洗心轴镀铬面，擦干
