复杂结构井的过套管测井技术应用

过套管测井是在已下套管井中完成的用以解决油气层识别、储层物性参数计算为目的的测井系列,在复杂井中用来代替常规的裸眼测井,以便减少在大斜度井中的测井事故,缩短测井周期。本文介绍了几种常用的过套管测井技术,并将其应用于大港油田的庄海401井。结果表明,过套管测井不仅解决了油气层判别的问题,也提供了较准确的物性参数,同时降低了施工作业的难度,缩短了占井周期,这一点对海上钻井尤为重要。

双层堤基的井涌破坏与无害管涌

双层堤基水文地质结构特殊，堤基承压水常具独特的“渗而不流”特征。在“不流”条件下，堤后盖层薄弱处受超高承压水头顶裂破坏，产生的局部冒水孔实属承压自流井，由此形成的管涌实质为井涌。底部进水的承压井流影响范围不大，井涌的破坏范围更小，据此可区分出有害管涌与无害管涌。前者局限于堤脚附近，小范围压渗为首选方案；对后者，既无需专门防治，更不必追求根治。     

Employment status passages and psychosocial well-being.

Medical students entering the labor market were studied to find out whether the improvement of psychosocial well-being depends on characteristics of their careers. Psychosocial well-being was described on the basis of psychosomatic stress symptoms, psychological distress (General Health Questionnaire), and strain resistance resources (Sense of Coherence). The 3-year follow-up showed that among women the improvement of strain resistance resources was delayed in the group with several entries into work. Among men the findings suggested associations between stress symptoms and career characteristics. Most of the results, however, did not support the hypothesis about the division of the participants into those with a stable career and improving well-being and those with a fragmented career and low well-being.

Optical and structural properties of MOVPE grown GaxIn1−xAs/InP strained multiple quantum well atructures

This paper presents a study of the structural and optical properties of strained GaInAs/ InP multiple quantum well (MQW) structures fabricated by LP-MOVPE. The composition of the Ga _x In_1−x As films ranged fromx = 0.17 tox = 1.0 and was determined by sputtered neutral mass spectrometry (SNMS) on thick layers. The structures of the MQW samples with well widths from 1.5 to 5 nm were investigated by high resolution x-ray diffraction (HR-XRD). Simulations of the diffraction patterns showed that transition layers of approximately 2 monolayer (ML) thickness with high lattice mismatch exist at the interfaces. Photoluminescence (PL) measurements indicate well widths of a multiple of a monolayer with local variations of one monolayer. The PL peak energies vary smoothly with the Ga concentration. These results were confirmed by optical absorption measurements.
