Description
Technical field
The utility model relates to well logging field, specifically a kind of transmitting sonic system of multipolar array acoustic tool PEEK material package.
Background technology
The operating principle of multipolar array acoustic tool device launches sound wave by transmitting transducer arrays, and acoustic signals is propagated in the earth formation, and by receiving transducer array received, the acoustic signals received can reflect the information such as the degree of porosity on stratum by process.Transmitting transducer arrays needs the transmitting sonic system be processed into by certain material to encapsulate, and encapsulates inner oiling to protect transmitting transducer.
The transmitting sonic system of conventional dipole acoustic instrument generally adopts fluorine rubber bladder encapsulate, and fluorine rubber bladder is packaged with following advantage: the acoustical coupling in well is better, little to acoustic attenuation, be conducive to transmitting acoustic energy to external radiation; Fluorine rubber bladder has certain toughness (elasticity), can play regulate pressure balanced effect to sonic system; Fluorine rubber bladder heatproof is better, can bear the temperature of in well 175 degree; Apparatus structure is simple, is easy to safeguard.But the shortcoming of fluorine rubber bladder encapsulation is easily corroded and gas cut.Under the high temperature and high pressure environment of carbon dioxide molecule in well, the inside penetrating into sonic system easily via leather bag forms compressed air bubble, carbon dioxide also can reside in leather bag inside simultaneously, make leather bag brittle, after downhole probe mentions ground, the rapid spatial expansion of these Compressed Gas, cause leather bag bulging, the gas simultaneously penetrating into leather bag inside also can cause leather bag to ftracture owing to expanding, instrument is damaged, some downhole probes log well do not complete time leather bag to be just damaged cracking, whole sonic system is caused to be poured into mud, probe and the device of sonic system inside are permanently damaged, in addition also because gas is to the damping action of sound wave, gas enters leather bag can make measuring-signal be deteriorated, and affects measurement effect.The corrosion that leather bag also can be subject to hydrogen sulfide gas makes leather bag softening transform.
Summary of the invention
Burn into is vulnerable to the hurtful deficiency of sonic system when logging well in order to overcome existing bladder transmitting sonic system, the utility model provides a kind of transmitting sonic system of multipolar array acoustic tool PEEK material package, the transmitting sonic system of this multipolar array acoustic tool PEEK material package can work under high temperature and high pressure environment, corrosion-resistant, anti-gas cut.
The technical solution of the utility model is: a kind of transmitting sonic system of multipolar array acoustic tool PEEK material package, comprise steel shell, interior axle, described steel shell inside is provided with the package cover of polyetheretherketonematerials materials, be fixed with monopole transmitting transducer, dipole transmitting transducer and Stoneley wave transmitting transducer from top to bottom successively between package cover and interior axle, and steel shell corresponding to above-mentioned transmitting transducer all has sound transmitting window; Described package cover bottom is equipped with piston.
Have piston to regulate chamber between described piston and the package cover on its top, piston lower portion is provided with spring, and steel shell corresponding to spring has overflow ducts.
The utility model has following beneficial effect: owing to taking such scheme; the package cover of this transmitting sonic system adopts PEEK (polyether-ether-ketone) material; making it not easily be corroded when logging well, avoiding carbon dioxide molecule to penetrate into sonic system inside, protection sonic system is without prejudice.Steel shell has sound transmitting window, and it is 865kPa that the polyether-ether-ketone package cover at sound transmitting window place can bear inside and outside differential pressure, and temperature is 175 degree, the overall withstand voltage 140MPa of sonic system, therefore, and this transmitting sonic system more high temperature high voltage resistant.
