Description
Technical field
The present invention relates to Seam Gas Prospecting apparatus field, more particularly to a kind of Intelligent supersonic for Seam Gas Prospecting
Imaging logging device.
Background technology
Coalbed gas logging refers to the difference in lithology physical property according to coalbed methane reservoir (coal seam) and country rock, utilizes naturally electric
Position, bilaterally (or sensing), microelectrode, compensation density, natural gamma, interval transit time, acoustic full-range, neutron porosity and
Calliper log etc. logs well it, among this, when acoustic logging refers to propagate in different rocks using sound wave, speed,
The acoustic characteristics such as the change of amplitude and frequency study the geologic section of drilling, judge a kind of logging method of cementing quality, sound
Ripple well logging again be divided into borehole compensated sonic log, long range acoustic logging, array sonic log, dipole acoustic logging, ultrasonic wave into
The various ways such as type well logging, wherein ultrasonic imaging well logging are using rotary super transducing, and wellbore surrounding is scanned, and remembers
Record echo waveform.
Coalbed methane reservoir (coal seam) and difference of the country rock in lithology physical property, are the physical basis of coalbed gas logging response.
Coalbed gas logging is according to coalbed methane reservoir (coal seam) and difference of the country rock in physical property, using natural potential, bilaterally (or sense
Should), microelectrode, compensation density, natural gamma, interval transit time, acoustic full-range, neutron porosity and calliper log etc. be to it
Log well.When sound wave is propagated in different medium, speed has very big difference, and decay, the change of frequency of wave amplitude
It is also different etc. acoustic characteristic.Acoustic logging is exactly to be cutd open using these acoustic characteristics of the media such as rock to study drilling geology
Face, is to develop a kind of faster logging method in recent years.Acoustic logging be divided into again borehole compensated sonic log, long range acoustic logging,
The various ways such as array sonic log, dipole acoustic logging, ultrasonic wave shaping well logging, wherein ultrasonic imaging well logging is to use
Rotary super transducing, is scanned wellbore surrounding, and record echo waveform.Acoustic logging is combined with seismic prospecting data,
Push up construction with solving underground, judge lithology, identification pressure anomaly layer position, detection and evaluation crack, judge fluid in reservoir
Properties, there is good development prospect.
, it is necessary to carry out drilling well before ultrasonic imaging well logging is carried out, but after the completion of drilling well, hole diameter can be influenced to send out by geology
Changing, it is generally the case that sandstone quality is hard, since elastic deformation can return to the original form after drill bit passes through, causes
Hole diameter reduces, and is commonly called as undergauge, and mud stone quality is loose, it may occur that hole collapse causes caliper expansion, is commonly called as expanding, therefore wellbore
Hole diameter cause not of uniform size everywhere, and existing ultrasonic imaging well logging apparatus centralizer structure is fixed, it is impossible to according to the big of hole diameter
The position of minor adjustment instrument shaft, causes transducer easily in the wellbore, to shift in the larger position of hole diameter, and becomes in hole diameter
Easily block small position, it is difficult to transducer is kept stable rising.
, it is necessary to disclose Occurrence of Coalbed Methane stratum into well by probing before ultrasonic imaging well logging is carried out.Stratum is in geology
Under the influence of the origin cause of formation or tectonic movement, by producing crustal stress under squeezing action, after passing through exposure by drilling well on stratum, primitively
The equilibrium state of stress is destroyed, and the factor such as the imperfection on stratum, brokenness and drilling fluid water enchroachment (invasion) influences in addition, will lead
Cause drilling shaft lining unstable, cause drilling well undergauge occur, phenomenon in expanding, the bad drilling well such as cave in.The size of drilling well hole diameter is not
One, bring great difficulty to well logging.Existing ultrasonic imaging well logging apparatus centralizer mechanism is fixed, it is impossible to according to well
The position of the size conditioning instrumentation axis in footpath, causes transducer to shift in the larger position of hole diameter, and in the position that hole diameter diminishes
Put and block, it is difficult to transducer is kept stable rising, not only influence logger safety, but also have an effect on the solution of log data
Release and handle.
