Abstract

The invention discloses a device for comprehensively testing working parameters of a casing. According to the device, an annular interlayer is formed in an existing oil casing; sensitive elements corresponding to the parameters that need to be tested are fixedly arranged in the annular interlayer; the setting types and number of the sensitive elements can be adjusted according to actual demand tomeasure related parameters; the sensitive elements are connected to a data processing end through data lines; well logging during drilling can be realized in a drilling stage through the device; the service state and the environment data of the casing at any position can be monitored in real time; and under the condition of not affecting the well construction cycle, a process is adjusted in real time to ensure high efficiency and safety of a wellbore string. In a well repair stage, data information of deformation situations, positions, environmental parameters and the like of the casing can beprovided in real time, a well repairing process is formulated accurately and efficiently, and the data in a well repairing process are monitored in real time.

Description

【Technical field】 [0001] The invention belongs to the field of oil pipes, and in particular relates to a device for comprehensively testing the working parameters of casing pipes. 【Background technique】 [0002] Petroleum casing is an important part of the wellbore string in the oil and gas field. In the traditional oil and gas field wellbore string engineering, the main function is to fix the well wall and prevent the well wall from collapsing. It is the most important physical barrier in the passage of oil and gas resources from the bottom of the well to the surface. ; In addition, in the development of unconventional oil and gas such as shale gas, the oil casing is directly used as a transportation channel for oil and gas resources from the bottom of the well to the surface. With the development of the petroleum industry, on the one hand, due to downhole complexity and other reasons, during the drilling process, the environmental conditions of the casing work process have...
