四川碳酸盐岩储层的储层岩性较为复杂,以前由于没有准确的地层岩性含量测井仪器,在地层特别是储层岩性的识别上可能产生多解性,最终导致解释失误。元素俘获谱测井(ECS)仪器通过测量地层元素的含量,可以提供精确的地层岩性组分,使测井解释更加准确。该仪器经在四川油气田的碳酸盐岩地层应用,消除了岩石成分的多解性,提高了解释符合率。 The reservoir lithology of carbonate reservoirs in Sichuan is rather complex. In the past, without accurate lithologic logging tools, the interpretation of stratigraphy, especially reservoir lithology, may have multiple solutions, leading to interpretation errors. Element-capture spectroscopy (ECS) instruments measure the amount of formation elements to provide accurate lithologic components of the formation for more accurate logging interpretation. The instrument by the Sichuan oil and gas fields in the carbonate rock formation, eliminating the multi-solution of rock composition and improve the interpretation of coincidence rate.
