【摘要】：利用測(cè)井資料來(lái)準(zhǔn)確計(jì)算5個(gè)獨(dú)立的剛性系數(shù)(C_(11)、C_(33)、C_(44)、C_(66)和C_(13)),以解決橫觀各向同性快地層最小水平主應(yīng)力的測(cè)井計(jì)算難題。通過(guò)聲速各向異性及黏土含量實(shí)驗(yàn)測(cè)量,分析并建立了聲波各向異性系數(shù)與黏土含量的函數(shù)關(guān)系及不同剛性系數(shù)之間的轉(zhuǎn)換關(guān)系,在此基礎(chǔ)上建立了一套利用測(cè)井資料計(jì)算各向異性快地層剛性系數(shù)及最小水平主應(yīng)力的方法。實(shí)際應(yīng)用表明,該方法與僅適用于慢地層的基于水平橫波速度的計(jì)算方法互為補(bǔ)充,可用于評(píng)價(jià)致密油氣儲(chǔ)集層巖石力學(xué)參數(shù),優(yōu)選壓裂試油層段。
[Abstract]:Five independent rigid coefficients can be accurately calculated by using logging data. The functional relationship between acoustic anisotropy coefficient and clay content and the conversion relationship between different rigidity coefficients are analyzed and established. On this basis, a set of methods for calculating stiffness coefficient and minimum horizontal principal stress of anisotropic fast formation using logging data are established. The practical application shows that, This method is complementary to the calculation method based on horizontal shear wave velocity which is only suitable for slow formation. It can be used to evaluate the rock mechanics parameters of tight oil and gas reservoir and to select the fracturing test zone.
