【摘要】 文章介绍了MPAL多极子测井仪器的设计思路及仪器组成。MPAL多极子阵列声波测井仪器利用多种组合模式,在裸眼和套管井中进行声波单、偶极阵列测井,偶极子横波直接测井,测量得到的数据可以直接提取软硬地层中的纵波、横波和斯通利波漫度参数来进行储层的地质评价。近几年在二连油田识别岩性、识别油气层、预测地层的破裂压力,利用各向异性检测压裂效果等应用效果较好。更多还原

【Abstract】 This paper introduces the design and structure of Multipole acoustic array logging(MPAL)instruments.Making use of multipole combination modes,MPAL instruments can perform acoustic monopole and dipole array logging and dipole S-wave direct logging in boreholes and cased wells.From the measuring results,the slowness parameter of P-wave,S-wave and stoneley wave in hard and soft stratums can be directly extracted to evaluate the geology of the reservoirs.In recent years,MAPL instruments have shown significant effects in many applications,such as lithology recognition,reservoir recognition,stratum fracture pressure projection and fracturing effect detection using anisotropy.更多还原
