Technical field
The utility model relates to the compensation formation resistivity logging instrument of frequency electromagnetic waves of oil well logging apparatus field, specifically is a kind of three phase place compensating resistance rate loggers.
Background technology
The formation resistivity logging instrument is a kind of measuring apparatus commonly used in the oil field prospecting exploitation, is used for determining oil saturation, the permeability on stratum, the intrusion of drilling fluid etc., is one of important means of seeking oil gas.The conventional instrument that uses mainly is to adopt inducing method and current focusing method at present, and the instrument of inducing method is the dual induction lateolog-8 logging instrument of the seventies, and is backward in technique, and certainty of measurement and investigation depth are relatively poor, can't use in the high resistant lithology; The instrument of current focusing is a dual laterolog equipment, is restricted in use, can't use in oil-base mud, air drilling, and certainty of measurement is not enough in the low-resistance stratum.
The novel array induction of external exploitation, array side, were subjected to same limitation in application facet, and involved great expense though performance and technical level increase substantially to instrument in recent years, were difficult to extensive use in conventional logging.Russia one tame geophysics company has released a kind of high frequency induction logging tool in recent years, housing by asymmetric transmitting coil system, electronic circuit and device electronic circuit is formed, adopted the frequency electromagnetic waves measuring principle, but its structure is one-sided placement transmitting coil, instrument can't carry out automatic verification and temperature-compensating, measurement result need be carried out temperature correction, influences the stability of certainty of measurement and instrument.
The utility model content
The utility model is exactly at the existing in prior technology defective, proposes a kind of certainty of measurement height, stable three strong phase place compensating resistance rate loggers.
Its technical scheme is made up of the housing of transmitting coil system, electronic circuit and device electronic circuit, and electronic circuit wherein partly comprises the preposition amplifying circuit of signal, emission control driver circuit, phase place and amplitude measurement circuit, digital circuit and power supply.Emphasis improvement part of the present utility model is a transmitting coil architecture layout, and it is the both sides that are symmetrically distributed in coil array by the symmetrical expression transmitting coil of three different spacings, and two receiving coils place the middle part of coil array.
The nearly spacing of three symmetrical expression transmitting coils is not less than 12 inches, far spacing is not more than 60 inches; Distance between two receiving coils is between 6 to 12 inches.
