METHOD
PREDICTING PERSPECTIVE OF AREAS FOR OIL AND GAS
 FIELD:
proximity evaluation of prospects of developed geological structures prior to
start of deep exploratory drilling.
SUBSTANCE: specimens are taken within bounds of
search section, magnetic parameters are measured, specimens are heated to
temperature of 450-500 C. Magnetic parameters are measured again and measured
values of parameters before and after heating are compared. Comparison results
are used to make judgment on presence of oil or gas deposit. Specimens are taken
from upper layer of soil horizon. Specimens are heated in presence of oxidizing
agent. Background specimens are taken in addition. Relation of values of
measured parameters of specimens before and after heating is compared with value
of parameter of background specimen. With twofold excess of relation judgment is
made on presence of oil and gas perspective areas. Magnetic susceptibility, and/or
residual magnetization of saturation, and/or saturation magnetization are chosen
as magnetic parameters. Oxygen-carrying atmosphere is utilized in the capacity
of oxidizing agent and heating is conducted in the course of 30 min. Specimens
are dried and ground to grains smaller or equal to 0.8 mm before measurement of
magnetic parameters.
EFFECT: enhanced authenticity of measurement
results, simplified method and decreased cost of its realization. 2 cl, 3 dwg
