Description

Technical Field

[0001] The invention relates to the technical field of oil production, in particular to an oil production component with a replaceable drill bit. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid flammable oil mineral asphalt. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in genesis, so they are collectively referred to as petroleum. Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid flammable oil mineral asphalt. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in genesis, so they are collectively referred to as petroleum. Reservoirs are rock formations with reservoir spaces that store oil and gas and allow oil and gas flows to pass through them. The spaces in the reservoirs include pores between rock fragments, cracks in rock cracks, and holes formed by dissolution. Pores are generally related to sedimentation, cracks are mostly related to tectonic deformation, and holes are often related to paleokarst. The size, distribution, and connectivity of the voids affect the flow of oil and gas and determine the characteristics of oil and gas extraction.
