从不同角度进行岩样可钻性试验,通过对须家河二段地层的研究,分析其地层各向异性的成因,并建立常规钻井条件下可钻性级值剖面图。研究表明,岩样切削面不同,导致岩石的可钻性级值差异较大。地层沉积作用、构造作用等因素,对岩石的分布差异有所影响。
The drillability test of rock specimen is conducted from different angles. Through the study of the second member of Xujiahe strata, the formation anisotropy of the strata is analyzed, and the cross-section diagram of drillability of conventional drilling conditions is established. The research shows that the different cutting planes of rock samples lead to great differences in the values of drillability of rock. Strata deposition, tectonic action and other factors, have an impact on the distribution of rocks.
