Cylindrical 90 Shore A Rubber Sleeve For Core Research
Core Holder Core Testing Rubber Sleeve High Temperature And High Pressure Fluororubber Cuff
Material of rock core rubber sleeve and sealing device: generally sodium butadiene rubber, fluorine rubber FKM , silicone rubber.
Our company mainly provides fluororubber core sheath application and high temperature and pressure testing environment.
70Mpa at temperature 230 ° C (about 12 hours) and 70Mpa at temperature 150 ° C.
A cylindrical rock sample taken from a hole using a ring core bit and other coring tools as required by geological prospecting or engineering.
The ore-bearing rock or ore taken from the ore body or ore layer of a solid mineral is called the ore core.Core is an important physical
geological data for studying and understanding underground geology and mineral resources
Core shape: cylindrical
Core action: Understanding underground strata and ore-bearing characteristics
Why core research is needed:
1.The age, lithology and sedimentary characteristics of the strata;
2.The physical and chemical properties of the reservoir and the conditions of oil, gas and water;
3. Reservoir characteristics and source oil indicators;
4. underground structure (such as fault, joint, dip Angle, etc.)
Basic data for qualitative and quantitative interpretation of various logging methods;The movement and distribution of oil, gas and water
in the production process, as well as changes in formation structure;The core can also be used for laboratory experiment analysis of water injection or various eOR methods and stimulation and injection measures, and it is an essential basic data for estimating oil reserves,
formulating reasonable development
