Description
Technical field
The invention belongs to petroleum drilling engineering field, more particularly to a kind of drilling well resistivity antennae.
Background technology
At the beginning of the 80's of 20th century, some fairly simple resistance can be measured with electromagnetic wave resistivity logging instrument is bored
Rate, subsequent going deep into due to research, electromagnetic wave resistivity logging instrument realizes multi-faceted, multi-angle development, while with brill
Measurement (MWD) and well logging (LWD) application there has also been greater advance, and not only precision improves a lot, and calculate effect
It is even more to have greatly improved in rate.
At present, it is that must survey project in high angle hole and horizontal well with electromagnetic wave logging is bored.Just with brill electromagnetic wave logging
Say, the slightly difference, but its principle is essentially identical such as instrument, investigation depth and longitudinal frame and measurement range of different company
, main difference is that the setting of coil array is different, the models of double receipts are sent out in common use one, the double hairs of the use also having are double to be received,
The model of the four double receipts of hair or more transmitting coils, the situation of plurality of transmitting coil is essentially all transmitting coil separation
Receiving coil both sides, form borehole compensation measuring instrument；Another is exactly that the coil spacing of send-receive is different, and coil distance is visited
Depth measurement degree is just big, but a disadvantage is that reducing the signal intensity at receiving coil；, can if the distance between two receiving coils are big
With increase rate and the resolution ratio of phase, the amplitude of response is become big, the ability that instrument recognizes thin layer, i.e. instrument can be reduction of
Resolution ratio reduction；Wherein conventional use of field frequency is relatively low (majority uses 1kHz), passes through the induced electromotive force of measuring receiver
Stratum is analyzed, but the signal intensity of antenna is low, can only carry out some simple measurements.In a sense, ground
Bed boundary (country rock) and formation anisotropy be influence resistivity log response feature in high angle hole and horizontal well it is main because
Element.
