Log supply exclusively full information on a cut of chinks. A continuity of measurement of various physical indicators are the basic advantage of these methods. Core selection - always incomplete, therefore a core characterises only separate intervals of the passed cut, logging diagrammes show a cut structure as a whole. Obtaining given каротажа drillings it is necessary to be first of all assured that received physical parametres at us authentic. It concerns not only registration of difficult physical parametres, but also to depth on a chink trunk. In the course of building of a chink it is consistently measured in the different ways. Modern researches of chinks are log in the course of drilling LWD (logging while drilling) allow to save time for research of chinks in this connection the zone of penetration of a filtrate of a chisel solution in a layer considerably decreases that leads to reduction of time for its development. By means of application neutron and lito-plotnostnogo log during drilling there is a possibility more correctly to estimate lithology and porosity of a layer. Application of azimuthal methods log allows to define a corner and an azimuth Layer on a layer, and also other structural elements of a layer necessary for effective geonavigation in the course of drilling. At drilling the given depths of a measure of the tool log drillings (MandD, LWD) and Geology-technological researches in the wells arrive. Having spent log on a cable, we receive a measure of depths logging a cable.
