Spontaneous potential well-logging is one of the important techniques in petroleum exploitation.

Cold treatment (4°C) and water logging stress enhanced and abscisic acid, H2O2, and salicylic acid repressed the levels of C-GS1 transcripts.
By a comprehensive study of all kinds of data (separatelayer well testing, temperature well logging,radioactive isotopes traces,coring……etc.),it is assumed that in each hydrofracturing job,a system of fractures (instead of a single one) parallel to bedding planes and stretched horizontally are produced.Each fracture is in the form of a pan-like pattern with the well axis as its centre, and distributed unevenly.The fact that promissing results are generally abtained in fracturing job in thick oil zones...
As an electric property of rocks, dielectric constant has been used in recent years as a new parameter in well logging. Essentially different from resistivity, dielectric constant is a measure of polarizability of rocks and its effect on the electric field is manifest only at the frequency of over dpzens of mega-hertz. For this reason, high frequency is used in studying the dielectric constant. With the help of condenser and high-frequency electromagnetic wave, the relationship between the dielectric ...
It is important to know the distribution of oil and water in a reservoir since the beginning of water flooding.Gudao oilfield has so loose a lithology that the distribution of oil and water can't be identified by means of the conventional coring method.This paper describes a method and the results for the study of the distribution of oil and water and the displacing mechanisms in a water wet sand- stone reservoir by using the secondary interpretation of the logging information, mathematical simulation...
