Abstract
The utility model is a lifting short section for short ship drilling tools, and which is a short section whose two ends are thread and is used for connecting thread of drilling tools under drilling so as to make a short ship with suspension card. The lifting short section is easily used, and both ends of thread can be used, and it is more practical than the standard lifting short section, lowering the overall costs. When blowout accidents occur, the single joint of the blowout preventer can be immediately connected, easy to control the wellhead.
Description
Affiliated technical field
The utility model relates to a kind of special tool that is used for the oil drilling drilling, particularly a kind of lifting instrument---lifting sub of drilling tool.
Background technology
Having only an end by the lifting sub of petroleum industry standard SY/T 5699 regulation is external screw thread, and an other end is not processed, and can only adopt threaded end to be connected with drilling tool.This lifting sub of on-the-spot use can not be gone into the well; Simultaneously owing to have only an end that screw thread is arranged, thread damage in the use, this lifting sub just needs place under repair, loses time; The 3rd owing to an end has screw thread, and on-the-spot the needs is equipped with more lifting sub, causes instrument to leave unused and wastes.
The utility model content
The purpose of this utility model is: a kind of pair of external screw thread lifting sub is provided, changes traditional lifting sub structure, adopt two ends to be provided with screw thread, any threaded one end can be threaded with drilling tool, overcome existing lifting sub, use inconvenience, the deficiency of waste material.
The technical scheme that the utility model adopted is: two external screw thread lifting subs are made up of body and drilling tool screw thread, body is a cylinder, there is axially extending bore at the cylinder center, it is characterized in that: the length of body (total length) is between 1.2-1.8 rice, and this body diameter (maximum outside diameter) is between the 88.9-279.4 millimeter.The two ends of body have the drilling tool screw thread respectively, and the drilling tool screw thread is an external screw thread.External thread form can adopt by specification: NC26 2 3/8IF, NC31 2 7/8IF, NC35, NC38 3 IF, NC44, NC46 4IF, NC50 4 IF, 6 5/8REG, 7 5/8REG, 8 5/8REG, NC56, NC61, NC70.
The carrying shoulder processing type of two external screw thread lifting subs can be processed into 90 ° of straight shoulders or 18 ° of slope shoulders.
The advantage of the utility model technology is: because two external screw thread lifting sub two ends all have screw thread to be utilized, can reduce the quantity of the standby lifting sub of situ of drilling well.Adopt two external screw thread lifting subs, can make full use of steel.This lifting sub scene is easy to use, and it is practical more to compare with the lifting sub that the foundation industry standard is produced, and saves the drilling well integrated cost.
The utility model intrinsic structure of lifting sub that not only breaks traditions is because the change of structure produces beyond thought effect.As when gas blowout accident takes place, can rob on the other end screw thread of two external screw thread lifting subs immediately that to take over control spray single.Rob take over control the spray single after, be convenient to control well head, striven for valuable time for preventing gas blowout accident.If adopt the standard upgrading pipe nipple, the other end without screw thread when blowout takes place, needs to change a large amount of joints, could be connected with blowout prevention is single, wastes time.
