New ideas and methods in the paper:1 The formulas on perforated casing collapse strength were deducted, which offereda convenient method to analyze the relationship between casing collapse strength and perforation;2 The stress and displacement formulas on the system of casing, cement anddeformation under the non-uniform load were deducted, which offered the theoretical found for designing optimally casing string;3 The relationship between structure in-situ field of whole oil field and casing failurewere studied, which offered the scheme for the prediction of casing failure. The process of study in the paper:1 For simulating the relationship between the structure in-situ field and the casingfailure in the oil-deformation, the tests of the uniaxial tensile, compress, tnaxial compress and dilatability were made on the samples of the drill cores from deformation of casing failure position in Yuejing II oil field.

本文的主要创新: 1推导出了射孔套管抗挤强度的解析式,为分析射孔与套管强度的变化关系提供了简便的方法; 2推导出了非均匀地层载荷作用下套管、水泥环和地层组合体的应力和位移解析式,并非均匀作用下套管柱优化设计提供了理论依据; 3研究整个油田区块构造应力场与套管损坏关系,为预测套管损坏提供了可行方案;本文的研究过程如下: 1为模拟构造应力场与油层段套管损坏关系,做了大量的岩石单轴抗拉、单轴抗压、三轴试验以及岩石遇水膨胀试验,获得了研究区块岩石的弹性模量、泊松比、内聚力、内摩擦角以及岩石的线膨胀系数,这此数据为本文研究油层段套管损坏机理研究的理论分析和有限元法提供了实验数据。

Scene data indicate that in the process of actual making the casing into the Horizontal Well ,people used to reduce friction coefficient between the stratum and the Casing, Change the friction type between the casing and the wall,use special casing and centralizer with oriented ring, even join the slurry in the internal casing in order to increase self-casing, etc.

现场资料表明,在实际套管下入过程中,人们往往采用的是减小套管与井壁之间的摩擦系数、改变套管与井壁间的摩擦类型,使用带有导向环的套管和扶正器,甚至在套管内部加入泥浆,以增加套管自重等方法,但这些方法并没有改变套管下入驱动力减少的现实,不能从根本上解决套管下入困难的问题。
