A well-ground joint parallel electrical method testing method and testing system

Abstract

The invention provides a well-to-ground joint electrical-method testing method and system. The well-to-ground joint electrical-method testing system comprises an in-well emission power supply subsystem, a ground collecting and acquiring subsystem and a master control and processing subsystem. By controlling emission electrodes in the in-well emission power supply subsystem and measuring electrodes in the ground collecting and acquiring subsystem, the well-to-ground joint electrical-method testing system can provide three power supply modes of in-well point source power supply, in-well dipole source power supply and well-to-ground joint power supply. The master control and processing subsystem can process and interpret the acquired data of the ground collecting and acquiring subsystem, and the geologic features of the surrounding area of boreholes can be effectively acquired. The well-to-ground joint electrical-method testing system is flexible in power supply modes, power supply, data acquisition and real-time simple processing of the data are integrated, and the well-to-ground joint electrical-method testing system is highly flexible and high in systematization and intelligence degrees.

Description

technical field [0001] The invention relates to a geophysical prospecting technology, in particular to a well-ground joint parallel electrical method test method and a test system. Background technique [0002] Drilling plays an important role in the exploration of resources and engineering geological conditions. Through drilling, the structure and structural characteristics of strata and rocks in underground geological bodies can be understood. Therefore, how to use drilling and ground space conditions to determine certain It is an important issue to explore and analyze the reservoir medium within the range. [0003] At present, for the exploration of the geological characteristics of the reservoir medium around the borehole, the main method is to simultaneously realize power supply and data acquisition in the borehole, test the parameters of the geoelectric field, and perform data processing on the data parameters obtained from the test, and further obtain the geological d...

Problems solved by technology

[0004] However, the geoelectric field parameter test carried out by the above method has a single power supply mode and cannot be flexibly controlled. In addition, the functions of power supply, collection and real-time simple processing of data are integrated, so the flexibility is poor, systematic and intelligent The degree is low, and the ability to distinguish the well-ground space with the help of the obtained electrical parameters is limited
