Embodiment Construction

[0054] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0055] Before the detailed explanation of the embodiments of the present application, the application scenarios in the embodiments of the present application are explained first.

[0056] The well testing device provided in the embodiments of the present application can be applied to the early development process of any shale oil well, and is used to obtain well testing data of the shale oil well in the early stage of oil production. The early stage of oil production refers to the stage during the soaking of shale oil wells and after the soaking wells are opened. The well test data in the early stage of shale oil well production refers to the pressure data changes of shale oil wells during the soaking period and the ...

Abstract

The embodiment of the invention discloses a well testing device and method and a computer storage medium, and belongs to the technical field of shale oil exploration and development. The device comprises a front baffle plate, a main body and a back plate, one end of the main body is connected with the front baffle plate, the other end of the main body is connected with the back plate, a cavity with an opening is formed among the front baffle plate, the main body and the back plate, the cavity is used for placing a pressure gauge, a gap is formed in the front baffle plate, and a telescopic supporting arm is arranged on the back plate. The supporting arm is used for fixing the back plate in the pipe wall of a Christmas tree, and the Christmas tree is arranged on a to-be-detected well. The well testing device provided by the embodiment of the invention can perform well testing on the oil well without being put into the oil well, so that the well testing data of the oil well can be obtained, and the information of the well testing data is provided for later oil well construction.

Description

technical field [0001] The embodiments of the present application relate to the technical field of shale oil exploration and development, and in particular, to an oil well testing device, method, and computer storage medium. Background technique [0002] With the continuous consumption of oil and gas resources, the contradiction between oil and gas supply and demand has become increasingly prominent. China's shale oil resources are very rich, and the development of shale oil can greatly alleviate the shortage of oil and gas resources in my country. In the process of shale oil development, well testing of shale oil wells is a very important stage. Among them, well testing refers to testing oil wells with special instruments to obtain pressure data of oil wells. [0003] In the related art, the well testing device of the oil well is put into the well of the oil well, so as to test the oil well. For example, wireline well testing devices. However, the high viscosity of shal...
