正交偶极声波测井技术在碎屑岩储层评价中的应用初探

正交偶极声波测井是一种测量地层岩石声学信息，进而分析地层各向异性的测井新技术，首次在渤海海域NB35—2—8井碎屑砂泥岩地层中应用，不仅获得了明下段主要砂体储层内部的非均质性特征信息，而且还获得了地应力方向和古流向等信息。这些信息的获得，有助于储层的精细描述与评价。     

下T6-361井多井防碰绕障技术

下T6—361井是一口双靶定向井，由于受地面和地质条件的限制，必须穿越9口井，其中最近的4口井防碰距仅为13—32m，钻井施工难度大，是一口较典型的多井防碰绕障定向井。在优化井身剖面设计、优选钻具组合、采用导向钻井技术的基础上，采取了一系列安全钻进措施，顺利钻至设计井深。对该井的地质工程设计、井眼轨迹控制及防碰绕障技术等进行了介绍，对同类型井的施工有一定的借鉴。

The Simulation of Impact Loads on Beam-type Structures using a Pseudo-dynamic Procedure

Abstract:  This study proposes an alternate method for the analysis of beams with solid cross-section or built as a framed structure and subjected to transverse impact loads from an external striker. The procedure used in the analysis is a combination of two essential tools using pseudo-dynamic techniques. The method reported here involves only one degree of freedom for the structure modelling and assumes an elastic contact between an external striker and the beam structure, which in reality does not happen. As only one degree of freedom is considered in the analysis, some important limitations are inherent to the method proposed here. Essentially, there is the difficulty of modelling the displacement field associated with the transient structure behaviour accurately, as a consequence of fast-rate impact loads. Another difficulty faced by the method refers to a local structure behaviour associated with contact loads. The present method can deal with large displacements in transversely loaded beams associated to a collapse mechanism having a simple geometry and defined with precision from a single parameter. This ensures reasonable accuracy in the evaluation of the strain energy absorbing capacity of transversely impacted beam structures using a single degree of freedom model in a pseudo-dynamic procedure.

Mixed anaclitic-introjective psychopathology in treatment-resistant inpatients undergoing psychoanalytic psychotherapy.

Utilizing data from the Riggs-Yale Project, 45 male and 45 female 18-29-year-old treatment-resistant inpatients undergoing intensive psychoanalytically oriented treatment were studied. Twenty-seven mixed-type anaclitic-introjective inpatients were compared with 29 "pure" anaclitic and 34 "pure" introjective inpatients. At intake, mixed-type inpatients were more clinically impaired (i.e., were more symptomatic, cognitively impaired, and thought disordered) and more vulnerable (i.e., less accurate object representations and more frequently used maladaptive defense mechanisms) in comparison with clearly defined anaclitic and introjective patients. Mixed-type patients, however, improved significantly more in the course of psychoanalytically oriented treatment, in terms of clinical functioning (i.e., symptoms, cognitive functioning) and psychological vulnerability (i.e., utilization of more adaptive defense mechanisms).
