Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.
Three are two kinds of
Circulating head: one kind for casing, the other kind for drill pipe, joint pin of casing circulating head is connected collar of casing, the drill pipe circulating head is connected with the drill pipe ' box thread, it is used to circulate mud before cementing. Type:
-simple type circulating head
-integral circulating head
-union circulating head
-Clamp type circulating head
-Drilling pipe circulating type
big union circulating head
-composed by its body, big union, casing joint
-its body is integral structure, bear high pressure
-It is alternative between casing head and cement head, convenient install.
Clamp type Circulation connector
-Composed by its body, clamp connector
-Clamp joint can be applied to different casing coupling, without being limited by the casing thread
-It is alternative between clamp connector and cement head, convenient install.
Drilling pipe circulating head
-The top is female screw of DP, the ends is male screw of casing.
-High quality alloy steel
-Integral structure, no weld, bear higher pressure
