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.
Oil Well Drilling Packer Type Y series
1,Structure
It mainly consists well washing mechanism, sealing mechanism, setting mechanism, locking mechanism and releasing
mechanism.
2,working principle
Set: Landing the packer to the reserved position in the well, pressure out in tubing, the piston moves up, and the pin is cut off, then the lock sets move up and the element is compressed. At the same time, the lock set ang lock ring lock each other, so that the element can not be recycled. During the process, seal the tubing annulus, the setting is completed.
Release: Lift the string, cut off the pin with the friction between element and the casing, the lock ring is without limit. The lock ring and lock set move down and release the stuck under the element back strech, and the packer is released.
Wash well: Increase pressure by 0.5 MPa to wash the well.
Feature:
1,Double-piston, low-pressure set explored, good sealing
2,Highly temperature -resistance and pressure-resistance glue tubing explored, stable, widely used.
3,Reasonable-design, high-pressure, overturn well-flushing with large emission
4,straight pull release, easy to operate and stable
