Problems solved by technology

However, the acquisition of well logging data is always after the drilling is completed, and the instrument is put into the well for measurement with a cable. The cable is difficult to put the instrument down; in addition, the wellbore is not in good condition, prone to collapse or plugging, and it is difficult to obtain well logging data

Abstract

The invention discloses a testing system of a logging while drilling ground machine. The testing system of the logging while drilling ground machine comprises a depth signal simulation module, a mud signal simulation module and a load signal simulation module. The depth signal simulation module can provide simulation depth signals of eight kinds of frequencies, and the pulse number and direction of the simulation depth signals can be selected through switches and buttons on a control panel; the load signal simulation module can provide two different kinds of load signals, and the load signals are selected through the switches on the control panel. A signal processing terminal of the testing system can decode and analyze a processing result of the logging while drilling ground machine and give out an assessment result. The testing system can test functions of each module of the logging while drilling ground machine and give out corresponding evaluation. In addition, the system can carry out long-term aging measurement on instruments.

Description

technical field [0001] The invention relates to the field of petroleum exploration and logging, in particular to a logging-while-drilling surface machine testing device. Background technique [0002] During the exploration and development of oil and gas fields, well logging must be carried out after drilling to understand the oil and gas content of the formation. However, the acquisition of well logging data is always after the drilling is completed, and the instrument is put into the well for measurement with a cable. It is difficult to put the instrument down with the cable; in addition, the poor condition of the well wall is prone to collapse or plugging and it is difficult to obtain well logging data. Since the drilling fluid is circulated during the drilling process to bring out the drilled cuttings, the drilling fluid filtrate always invades the formation. Therefore, when logging after drilling, the various parameters of the formation are different from those when th...
