Oil and natural gas exploration and development can be divided into land mining and offshore mining. The oil and natural gas stored in the crust accounts for roughly 60% on land and 40% offshore. The oil and gas in the offshore crust such as the Bohai Sea and the South China Sea are also exploited. significant.
Before the industrialization and large-scale application of titanium alloys, the commonly used logging instrument casings were made of 45 steel, 40Cr steel, and 30 MoVNb steel, but none of them could meet the needs of modern technical logging, modern high-tech oil and gas exploration And development requires that the metal casing of the logging tool can not only withstand the pressure of > 98 MPa, but also resist the corrosion of underground crude oil and various media, and in the logging, it must also have a small absorption rate of natural gamma rays. , and should not have a shielding effect on the geomagnetic field. From these performance requirements, Ti 15V-3Cr-3Sn-3Al Titanium Strip is good materials for making logging tool housings.
