What are the general requirements for geophysical prospecting companies? Geophysical exploration is useless now!

Why geophysical prospecting is useless? I have to admit that geophysical exploration has a bad reputation now. I think there are several reasons:

First, geophysicists do all the work. In order to create economic benefits, that is, to get the project, many problems that geophysical exploration can't solve or can't solve are justly said, and many problems such as geophysical exploration solutions are not raised with geologists or Party A, which leads geologists and Party A's mine boss to think that geophysical exploration is magical and omnipotent, but many geophysical exploration results are not satisfactory in the end, which eventually leads geologists and mine bosses to have prejudice against geophysical exploration.

Second, geophysical prospecting units and technicians are uneven. Many units, equipped with geophysical prospecting equipment, do geophysical prospecting by themselves, learn geological geophysical prospecting, learn surveying geophysical prospecting, and even recruit some junior high school graduates to do geophysical prospecting. The leader thinks that geophysical exploration can be done as long as he can operate the instrument, but he doesn't understand the basic knowledge of geophysical exploration, that is, he simply operates the instrument, which leads to the failure to master the most basic and important field data acquisition link, let alone carry out in-depth inversion processing and interpretation. Even professional geophysicists rarely study and study hard for one reason or another (such as time limit, etc.). ), especially on the basis of existing geophysical knowledge, they simply think that geophysical anomalies are mine anomalies and drilling holes.

Third, the external environment, that is, the geophysical prospecting market is becoming more and more chaotic. At present, the market is not a market for technology, but a market for price. First of all, many geophysical prospecting fees are still implemented according to the 07 standard, but the cost of manpower and material resources has increased many times. Even if the profit is negligible according to the 07 budget standard, some Party A still ask for a discount on this basis. In order to have projects (competition among geophysical prospecting units lowers prices) and pursue the maximization of economic benefits, all geophysical prospecting units now work for the purpose of completing workload, not for work. Many involved feasibility studies and experiments are omitted, and many necessary links are omitted, which greatly reduces the reliability of field data and interpretation. What's more, I fabricated data without field construction, which led to self-deception. I also want to advise those leaders and the boss of Party A that the unit with low quotation is definitely good, but have you calculated the geophysical exploration cost for them? Do you dare to use the geophysical results they quoted below the cost?

Fourth, at present, many unit leaders and mine leaders of Party A are geologists who don't understand geophysical exploration. Without consulting geophysicists, they randomly designed geophysical exploration for the work area, did not conduct feasibility study and experiment, and did not conduct targeted analysis. The final geophysical exploration results can be imagined. If the geophysical exploration results are well verified by drilling, it is said that the geological analysis is in place; if the geophysical exploration results are not well verified, the geophysical exploration will be delayed.

Generally speaking, geophysical prospecting is only a means of geological exploration, which can help and guide geologists to carry out the next work (such as drilling). ), but geophysical prospecting has its multiple solutions, which requires the joint efforts of geophysical prospecting and geologists to eliminate multiple solutions as much as possible and finally achieve the goal of prospecting. Finally, I would like to borrow a sentence from my friend to encourage you: "Geophysical exploration, not knowing geology, not thinking;" Geology, do not understand geophysical prospecting is no way out. "

As for the requirements for geophysical exploration, the first is the feasibility study and experimental analysis of geophysical methods, the second is the authenticity and reliability of field data, and the third is the level of comprehensive research and interpretation analysis in the later period (combining geological and geochemical methods). Several steps are interlocking and must be taken seriously.
