Development of downhole gravimeter on modern highly sensitive elements on the basis of film accelerometers, providing high reliability of operation, for solving various geological problems: study of interwell space outside the well and below the well bottom to identify ore bodies; detection of oil targets and washed zones of oil fields in the late stage of development; control of gas injection and consumption in underground gas storages, etc. is proposed. Proceeding from real listed problems, the necessity and opportunity of creation of a downhole gravimeter-gradientmeter with sensitivity (0.05-0.1) - 10” 5 m/sec 2 has been scientifically proved. Such sensitivity is provided at the expense of high sensitivity of sensors, computer introduction of temperature corrections, consideration of device position in a borehole. There are theoretical calculations of possible gravity anomalies and its gradients over objects of regular geometric shape: a sphere, a vertical cylinder, a horizontal formation of finite thickness. The results of the calculations are compared with field observations during the exploration of copper and sulfide deposits and oil and gas fields. Experimental studies of the main units of the borehole gravimeter equipment were performed and their laboratory and bench tests were carried out, which confirmed the correctness of theoretical calculations.

For a number of years LMI in cooperation with South Kazakhstan TOMGP conducts large-scale studies by dipole inductive profiling (DIP) on polymetallic deposits of Central Kazakhstan.

The structural plan of the Precambrian is characterized by a wide development of the so-called dome-like structures - gneiss-migmatite domes, in the central parts of which the most intensively granitized rocks are exposed. When mapping such structures in recent years widely and successfully used materials of airborne and ground magnetic surveys. ...

Detailed geologic mapping of sedimentary rock strata based on ground magnetic survey data and solution of structural problems in the areas of their development is sharply limited until now. This is explained by the usually very low magnetization of sedimentary formations, their weak differentiation by magnetic properties and gentle bedding, which is characteristic of the territory under consideration. ...

Difficulties arising in detailed geological mapping of vast sodden and forested areas, in some cases successfully overcome the application of geophysical methods. ...
