Description
technical field:
The utility model relates to a kind of spectrum well logging application detection cell, belongs to petroleum exploration and development geological logging pneumatic cell technical field.
background technology:
In all energy in the world today, oil is one of most important strategic resource.It is not only the major impetus of modern Economy Development, and a kind of military resources and diplomatic resource, be the chip of international relations game especially.Oil has now become the lifeblood of national economy, the guarantee of safety, and it is directly connected to national economic development, steady politics and national security.Therefore, greatly develop China Petroleum, increase oil gas and supply with, reduce the degree of dependence to imported crude oil, product oil, both met the requirement of national economy energy industry, be conducive to again safeguard national economic security.
Greatly develop petroleum industry, must strengthen petroleum prospecting dynamics, but oil is as non-renewable resources, the complicacy of its formation condition and architectonic polytrope, making exploration is a very risky engineering.With regard to current exploration level, exploration success ratio is high not enough, this means the waste of huge exploration investment.Therefore, how to improve exploration success ratio, scientific evaluation exploration effects, effective evaluation trap, accurately implements hydrocarbon-bearing pool scope, for oil-field development lays a good foundation, seems very important.In petroleum geology exploration process, physical prospecting, drilling well, well logging, test, well logging are indivisible related links, but how to evaluate and find that hydrocarbon zone is a most important ring in exploration process, this has just determined the critical role of well logging industry in whole petroleum industry.
