MAJOR STAGES IN THE DEVELOPMENT OF HYDRODYNAMICAL WELL LOGGING AND FORMATION TESTING WITH WIRELINE FORMATION TESTERS

Chronologically, all stages of the Soviet/Russian manufacturing of well logging tools for direct logs have been considered: wireline formation testers (OPK) and wireline hydrodynamical well logging tools (GDK). Since 1959 and up to the latest days, the history of the development of this trend in the USSR and Russian Federation has been created just by VUF VNIIgeofiziki and ОАО NPP VNIIGIS OJSC. Dozens of GDK and OPK tool types designed for oil, gas, coal and water horizons have been developed. Totally, over 1,000 wells were tested and logged. Our methods compete with new developments of leading western geophysical companies on a price/quality criterion.

DEVELOPMENT OF LOGGING-WHILE-DRILLING (LWD) TECHNOLOGIES BASED

ON A RUSSIAN TELEMETRY UNIT WITH AN ELECTROMAGNETIC COMMUNICATION CHANNEL

The results of the pilot field tests of an LWD unit with a 3TK-42KK telesystem have been given. Possibility in principle to record and transmit a great amount of data through the electromagnetic communication channel from a induction logging module and a neutron one simultaneously while drilling has been shown.

EXPERIENCE IN USE OF A BOTTOMHOLE MOTOR WITH A BUILT-IN MODULE FOR MEASURING GEOPHYSICAL AND TECHNOLOGICAL PARAMETERS

An option of positioning measuring sensors maximally close to the bottomhole (by means of designing a bottomhole motor with a module built-in in its lower part) has been considered. A DRZ-106.TS motor design with a built-in module has been described. Advantages of its practical use have been given.

search indication of the technology is the amplitude and frequency spectra of the longitudinal waves.

D E TE R M IN A TIO N OF THE H Y D R O D Y N A M IC A L CHARACTERISTICS OF THE ROCKS BY THEIR N A T U R A L S TR E S S E D -S TA TE “M EM O RY"

A novel method for the determination of the hydrodynamical characteristics of the rocks (on the core adjusted to in situ pressure in the wet/dry pressure cham­ ber) has been proposed. The method is based on the recovery of the natural stressed-state of the rock which occurred in situ from the rock “memory” The method works by picking up the elastic wave propagation time vs core pore pressure with its loading rate not exceeding the plastic deformation relaxation one, and followed by the subsequent evaluation of a formation hydrofrac pres­ sure, rock yield stress and maximum admissible formation depression.

WIRELESS TELEMETRY SYSTEMS FOR DIRECT FORMATION OPERATION MONITORING IS THE FUTURE OF OILFIELD GEOPHYSICS

An example of using a direct formation-monitoring telemetry system in lateoperation fields has been given. Wireless telemetry systems allow recording data during the well operation without lifting the tool or production equipment to the surface. The options of mounting a system with using a simultaneous separate operation technology have been suggested.
