Abstract

The invention discloses a well drilling cementing cement head, and relates to the field of petroleum development well drilling. The well drilling cementing cement head comprises a cement head body. An upper connector is connected to the upper end of the cement head body in a threaded manner, a main cement head through hole and an auxiliary cement head through hole are formed in the cement head body, stop pin cock holes are radially formed in the cement head body, stop pin cocks are arranged in the stop pin cock holes, main cock through holes, auxiliary cock through holes and oblique cock through holes are formed in the stop pin cocks, the main cock through holes are formed in the stop pin cocks in the main cement head through hole, the auxiliary cock through holes are formed in the stop pin cocks in the auxiliary cement head through hole, the main cock through holes are perpendicular to the auxiliary cock through holes, one end of each oblique cock through hole is communicated with the corresponding auxiliary cock through hole, and the other end of each oblique cock through hole is communicated with the main cement head through hole; one end of each stop pin cock is connected with a stepper motor, and the other end of each stop pin cock is connected with a cock position indicating rod. The well drilling cementing cement head has the advantages that the main through holes and the auxiliary through holes can be reliably and accurately opened or closed without manual operation, and the cement head can be developed towards the automation direction and can be easily and safely operated.

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. At present, there are two retaining pin structures for cement heads. One is that there are two retaining pins arranged horizontally. The two retaining pins are manually operated to move to the left and right sides to open the channel, and the rubber plug or setting ball goes down. The other is a horizontally arrange...
