Description

technical field [0001] The invention relates to an oil field block simulation analysis method in the petroleum field. Background technique [0002] In the field of petroleum engineering, casing failure in oil fields is usually referred to as casing damage and casing deformation, referred to as "casing damage and casing deformation" for short. Casing failure refers to the general term for deformation, rupture, dislocation and other damage forms of casing caused by engineering, geological, production dynamic changes and other factors in the process of oil field production when the load on the casing exceeds the bearing capacity of the casing. During the development of oil and gas fields, especially in the middle and late stages of oil and gas field development, the failure of casing is a chronic disease that plagues the development of the petroleum industry in my country and even the whole world. It is also one of the key problems affecting the development of the petroleum in...
