使用螺杆钻具操作规程

DHM MANUAL

1入井前检查。

1 CHECKING BEFORE TRIPPING IN

1.1检查规格型号，记录系列号等相关数据。

1.1 CHECK TYPE AND SPECIFICATION, RECORD SERIEL NUMBER AND RELATING DATA

1.2 检查丝扣、外观等有无损坏。

1.2 CHECKING THREAD AND OUTLOOK

1.3 检查旁通阀是否工作正常。

1.3 CHECK BYPASS V ALVE

1.4 如果是弯螺杆需检查其弯度及弯向是否与其标记方向一致。

1.4 CHECK THE MOTOR BENT WHICH IS WHAT YOU WANT

1.5 丈量长度和内外径并做好记录。

1.5 MEASURE LENGTH AND RECORD OD &ID

2 入井使用。

2 DHM IN HOLE MANUAL

2.1 螺杆钻具入井前要在井口进行试运转，并记录压降。正常压降为300psi(145psi=1M)左右，如果压降不正常不得入井。试螺杆时不得带钻头。

2.1 CHECKING MOTOR BEFORE PUTTING IN HOLE RECORD PRESURE DROP ,ORDINARY, IT SHOULD BE 300 PSI. IF

PRESSURE DROP IS ADNORMAL, THE DHM CAN NOT BE PUT IN HOLE. WITHOUT BIT WHILE TESTING MOTOR.

2.2 下钻时控制下放速度，遇阻时应开泵循环划眼时视井下情况，间断转动钻具防止划出新井眼。

2.2 CONTROL SPEED WHILE PUTTING DOWN ,WHEN BLOCK, WE SHOULD PUMP ON AND FLUSH ACCORDINGLY, BUT TRY ALL THE BEST NOT TO DRILL A NEW HOLE

2.3 下钻到底开泵正常后记录排量、泵压。

2.3 AFTER GET THE BOTTOM, PUMP ON AND RECORD FLOW RATE AND PUMP PRESSURE.

2.4 钻头接触井底逐步加压，调整到螺杆最佳工作压降，记录泵压，钻压。

2.4 AFTER DRILL BIT REACHED BOTTOM, ADD DOWNFEED GREDUALLY, ADJUST MOTOR TO BEST WORKING CONDITION,RECORD PUMP PRESSURE AND WOB.

2.5 如果在钻进时泵压突然升高，就立即停泵，上提钻具，核对循环压力，如正常可恢复钻进。

2.5 WHILE DRILLING, THE PUMP PRESSURE SUDDENLY GETTING HIGH , WE SHOULD PUMP OFF IMMEDIATELY, PULL BACK BHA ,CHECK FLUSH PRESSURE, IF OK , KEEP GOING.

2.6 使用螺杆钻具应控制钻井液含砂量小于0.3%。

2.6 CONTROL MUD SAND CONTANT LESS THAN 0.3%

2.7 如遇泵压有大的变化，及时停泵分析原因。

2.7 IF PUMP PRESSURE CHANGE GREATLY , PUMP OFF AND CHECK WHY.

2.8 记录螺杆的使用时间，不要超过推荐使用时间。

2.8 RECORD MOTOR USING HOUR, NOT USE IT OVERTIME

3 维护保养。

3 SERVICE

3.1 螺杆钻具起出后，清洗干净，保养丝扣。

3.1 after motor be taken out of hole, clean it totally and service thread. 3.2 检查各零件的安全性（各部位丝扣有刺坏、本体有无弯曲变形、轴承磨损等），做好记录，根据使用时间，及时返厂大修。

3.2 check every parts,(thread,motor body outlook.and bears) make record, do service according to hours be used.

3.3 若暂停使用或长时间不用，向螺杆内注入少量的机油，以防腐蚀。

3.3 if the motor will be put in store for long time, fill some oil for anti rust.
