长25-29井卡钻事故的处理

长２５－２９井在完井阶段通井过程中发生粘附卡钻事故，在处理卡钻过程中又发生卡套铣筒、井漏、溢流等事故及复杂情况。通过对井下情况的认真分析，采取先堵漏后循环再解卡的处理方案，顺利地解除了该次卡钻事故，大大地减少了经济损失。     

高效铣环在胜科1井事故处理中的应用

胜科1井是中国石化的一口重点科学探井,在钻至井深5001m时因井眼缩径发生了卡钻事故。由于井底存在直翼扩大器、PDC钻头等含有硬质合金的落鱼,普通铣鞋无法完成套铣打捞作业,为此,专门设计了一种高效铣环。该铣环的切削元件选用了一种硬度达93.2 HRA的钛合金,经铣槽镶焊在本体上;本体选用了40CrNiMo厚壁管材,并进行了调质处理;连接螺纹选用了双级梯形同步螺纹。在胜科1井的应用表明：切削元件的强度满足了切削扩大器切削翼和PDC钻头胎体的需要,其齿形、布齿方向和出刃高度设计合理,提高了切削速度;本体性能高,切削元件焊接性能较好;双级梯形同步螺纹有效增加了连接部位的强度,具有较高的上扣扭矩,承受冲击载荷能力强。高效铣环在该井的成功应用,为今后同类型井的事故处理提供了借鉴。

Novel,liquid crystal formula to overcome LTPS LCD image sticking without adjustment of gamma code,optical, VHR and IS evaluation

In this article, novel n-FFS liquid crystal material from Slichem was used in order to elevate the anti-backlight long aging effect; a trace amount of free radical trap HALS-like additive was added, the principle of which can be expressed via Denisov cycle, confirmed by measuring the temporal VHR changes in test cells; three different resolution (FHD ~ QHD) models paired with N19 and N21 were selected for testing by comparing the actual panel. It is verified that the optimized material greatly improves the image sticking performance of the panel and keeping optical performance.     

Analysis of image sticking on a real MVA Cell

Abstract— Image‐sticking phenomenon is one of the most important issues affecting LCDs, especially LCD TV. It is known that image sticking is caused by residual DC voltage. An analysis of the cause that induces image sticking on a real LCD cell is very difficult to perform and is rarely reported. In this paper, the impurities that cause boundary image sticking on a real MVA cell was analyzed by examining a cross section of a cell, the bulk LC layer, the vicinity of the LC layer, the LC layer/PI alignment film interface using microanalysis methods such as infrared micro‐spectroscopy (μ‐IR) and micro‐sampling mass spectrometry (μ‐MS). It is clarified that there is quite a bit of aromatic acid at the boundary of the image‐sticking area than in the normal area at the LC/PI alignment film interface on the color‐filter side, not the TFT side, and it is assumed that aromatic carboxylic acid, a negative charged material, is condensed at the LC/PI alignment film interface on the color filter side by an electrically driven DC component inducing an electric‐condenser residual DC voltage.

喷雾干燥粘壁的原因与解决途径

对喷雾干燥粘壁的类型和原因进行了分析。喷雾干燥粘壁主要有半湿物料粘壁、低熔点物料的热熔性粘壁和干粉表面粘附三种类型。半湿物料粘壁主要与喷雾干燥塔结构、雾化器结构、安装、操作以及热风在塔内的运动状态有关。物料熔点低于干燥温度时容易产生热熔性粘壁。干粉表面粘附与塔壁的几何形状、粗糙程度、空气流速、静电力等有关。提出了解决各种类型粘壁的技术措施。
