【摘要】：裂縫性儲(chǔ)層中裂縫的發(fā)育特征對(duì)儲(chǔ)層產(chǎn)能有重要影響,側(cè)向類測(cè)井由于其較強(qiáng)的電流聚焦特性,常用于裂縫性油氣藏的評(píng)價(jià)工作。陣列側(cè)向測(cè)井儀是一種新型的側(cè)向測(cè)井儀器,具備更強(qiáng)的電流聚焦能力和更高的縱向分辨率�；谄桨鍫盍芽p模型,建立三維宏觀各向異性球狀介質(zhì)模型,運(yùn)用三維有限元數(shù)值算法,研究了水平井中陣列側(cè)向測(cè)井儀在裂縫性地層中的響應(yīng)特性。研究表明:儀器響應(yīng)隨裂縫角度的變化會(huì)出現(xiàn)幅度差極性變化,且臨界角大小與裂縫孔隙度有關(guān);儀器響應(yīng)隨裂縫孔隙流體電阻率的增大而增大,基巖電阻率與裂縫孔隙流體電阻率比值小于100后,裂縫孔隙流體電阻率變化對(duì)儀器響應(yīng)影響不大;儀器響應(yīng)隨基巖電阻率的增大而增大。該研究為裂縫性儲(chǔ)層的定性、定量評(píng)價(jià)提供一定參考依據(jù)。
[Abstract]:The characteristics of fracture development in fractured reservoirs have an important influence on reservoir productivity. Lateral logging is commonly used for evaluation of fractured reservoirs because of its strong current focusing characteristics. Array lateral logging is a new type of lateral logging tool, which has stronger current focusing ability and higher longitudinal resolution. A three-dimensional macroscopic anisotropic spherical medium model is established, and the response characteristics of the horizontal well array laterolog in fractured strata are studied by the three-dimensional finite element numerical algorithm. The study shows that the response of the instrument to the variation of the fracture angle will change the amplitude difference, and the critical angle is related to the porosity of the fracture. The response of the instrument increases with the increase of the pore fluid resistivity, and the resistivity of the bedrock and the pore fluid resistivity is less than 100. The change of the resistivity of the fractured pore fluid has little influence on the response of the instrument, and the response of the instrument increases with the increase of the resistivity of the bedrock. Test the basis.
