Multifunctional induction logging simulated experiment teaching system

Abstract

The invention relates to a multifunctional induction logging simulated experiment teaching system. The system comprises a coil system, a simulated formation scale ring distributed in the radial direction of the coil system, and a measurement and control system connected with the coil system, wherein the coil system is a nine-coil system and comprises nine coaxially-arranged coils which are three transmitting coils and six receiving coils; nine simulated measurement modes formed by combining three transmitting modes and three receiving modes can be formed under the control of the measurement and control system; the simulated formation scale ring consists of a transverse simulated ring and a longitudinal simulated ring; the transverse simulated ring consists of eleven concentric hollow copper pipes; the longitudinal simulated ring consists of three concentric hollow copper pipes; each scale ring can be connected to any resistor and used for simulating formation conditions at different electric conductivity and different relative positions; and the measurement and control system is used for controlling different combinations of the transmitting coils and the receiving coils and analyzing a longitudinal geometric factor curve and a transverse geometric factor curve of the coil system consisting of different combinations and an induction logging scale principle, so that the coil characteristics of an induction logging instrument are understood.

Description

technical field [0001] The invention relates to the field of experimental teaching equipment for "Well Logging Methods and Principles" in petroleum colleges and universities. The product is mainly used in the teaching of simulation measurement experiments of useful signals and useless signals of neutron arrays in induction logging and array induction logging. Background technique [0002] Well logging is an important field of earth science and one of the main engineering technologies of oil and gas exploration and development. Induction logging is an important source of information in formation evaluation and related application fields, especially array induction due to its rich measurement information. It occupies an extremely important position in logging technology. "Well Logging Methods and Principles" is one of the most important professional courses of exploration technology and engineering majors (logging direction) in petroleum colleges and universities. The main tas...

Problems solved by technology

However, due to the following reasons, the experimental teaching cannot be carried out, so that the basic method and principle of this course cannot be verified by the indoor teaching simulation experiment

The specialty targeted by the induction simulation logging system is very distinctive (currently only a few petroleum colleges are involved in the colleges and universities setting up this specialty direction), and there are no corresponding manufacturers at home and abroad (generally only for actual field operation instruments, and do not provide multifunctional simulation experiment teaching), and other fraternal colleges have not carried out similar work from the perspective of laboratory teaching. Therefore, it is pioneering for theoretical and practical teaching to "move" the logging site to the laboratory for simulation experiments
