Embodiment Construction

[0032] Such as figure 1 , 8 As shown, the wireless remote control automatically controls the rotary cement head, including the rotary injection head 1, the cement head 2, and the position indicator 3 connected sequentially from top to bottom, and the wireless remote control system 4 is set on the cement head 2.

[0033] Such as figure 2 As shown, the rotary injection head 1 includes a central tube 1-1 with a central hole 1-2, and two through holes 1-3 communicated with the central hole 1-2 are arranged on the central tube 1-1 to form a four-way central tube . The rotary union 1-4 is sleeved on the center tube 1-1, and the combined sealing ring 1-5 is arranged between the upper and lower ends of the rotary union 1-4 and the center tube 1-1, and the rotary union 1-4 A ring cavity 1-6 connected to the through hole 1-3 of the central tube 1-1 is arranged inside, and two interfaces 1-7 connected to the ring cavity 1-6 are set on the rotating union 1-4. The two interfaces 1-7 o...

Abstract

The invention provides a wireless remote-control automatic-control rotary cement head, and relates to the field of oil development and well drilling, in particular to a cement head used during drilled well cementing. The wireless remote-control automatic-control rotary cement head comprises a rotary injection head, a cement head body and a position indicator which are sequentially connected to one another from top to bottom; and a wireless remote-control system is arranged on the cement head body. A process of opening a stop pin cock and feeding a rubber plug or a setting ball can be finished automatically in a wireless remote-control manner, torque can be transmitted to a lower drill in a rotating manner, so that the lower drill can rotate, and the well cementation quality is improved.

Description

technical field [0001] The invention relates to the field of drilling for oil development, in particular to a cement head used for drilling and cementing. Background technique [0002] With the development of deep well and ultra-deep well drilling technology and the characteristics of high risk and high investment in offshore and deep well oil and gas development, HSE (health, safety, environmental protection) requirements are getting higher and higher, and faced with problems such as excessive length and weight of pipe strings, Therefore, conventional cement heads can no longer meet the needs of land drilling and completion and offshore oil and gas development. In order to improve the cementing quality, it is necessary to rotate the liner during running in, drilling fluid circulation or cementing, which requires a rotary cement head to rotate at the wellhead. In order to improve operational safety, it is necessary to design remote control rubber plug and setting Ball deliv...
