摘要： Sensors are attached directly to portions of the sand screen of a gravel packing assembly, with connectors to the sensors run through elements of the screen that are hollow for that purpose. The hollow element can be the trapezoidal wire that is circumferentially wrapped to form the outer screen or one of the outer spacers used to provide a stand-off of the wire from the underlying tubing. Sensors can detect such conditions as pressure, temperature, flow rate, density, etc., and can provide real-time information on the effectiveness of gravel placement during packing and on well conditions during production.

摘要： The flow apertures of a perforated mandrel are temporarily sealed by plugs which are made of a sacrificial material, for example, zinc, aluminum and magnesium. The sacrificial plugs prevent dirty completion fluid from passing through and in and out of the screen as it is run into the hole, thereby protecting the screen from plugging. During the time the screen mandrel is temporarily sealed by the sacrificial plugs, cleaning fluid is circulated through a work string and is returned through the annulus between the screen and the open well bore for removing filter cake, drilling debris and lost circulation material. After the annulus has been cleaned, the annulus is filled with an acid solution or caustic solution, which dissolves the sacrificial plugs. In an alternative embodiment, each sealing plug has a body portion and a stub portion which project into the mandrel bore. The sealing plug body portion is intersected by a vent pocket which is sealed by the stub portion. The screen mandrel flow apertures are opened by mechanically shearing the stub portion of each sealing plug with a milling tool run on a concentric tubing string.
摘要翻译：穿孔心轴的流动孔通过由牺牲材料例如锌，铝和镁制成的塞子临时密封。牺牲塞防止肮脏的完井液在其进入孔内时通过和进出筛网，从而防止屏幕堵塞。在屏幕心轴被牺牲塞临时密封的时间期间，清洁流体通过工作线循环并且通过屏幕和开放井眼之间的环带返回，用于去除滤饼，钻屑和流失物质。在环已被清洁之后，环形空间填充有酸溶液或苛性碱溶液，其溶解牺牲塞。在替代实施例中，每个密封塞具有突出到心轴孔中的主体部分和短截线部分。密封塞主体部分由通过凹口部分密封的通气口相交。通过在同心管柱上运行的铣削工具机械剪切每个密封塞的短截线部分来打开丝网流道孔。

摘要： A compact, retrievable packer has a unitary mandrel body which is intersected by one or more longitudinal production bores. The running length of the packer is reduced and premature set/release are prevented by a lock assembly which releasably locks the lower setting wedge to the packer mandrel. The lock assembly includes one or more locking dogs mounted within mandrel pockets for radial extension and retraction. The locking dogs are extended into an annular slot formed between a retainer collar and the packer mandrel. The lower setting wedge is secured by threaded engagement with the retainer collar. When the locking dogs are extended, the lower setting wedge is blocked against longitudinal displacement, thereby opposing setting forces applied to anchor slips. The locking dogs are held in the locked position by brace rods which are releasably blocked by a shifting sleeve mounted in one of the packer mandrel bores.
摘要翻译：紧凑的，可回收的封隔器具有与一个或多个纵向生产孔相交的整体心轴体。封隔器的运行长度减小，并且通过将下设定楔可释放地锁定到封隔器心轴的锁组件来防止过早的设定/释放。锁组件包括一个或多个安装在心轴袋内用于径向延伸和缩回的锁定爪。锁定爪延伸到形成在保持架环和封隔器心轴之间的环形槽中。下固定楔通过与保持器套环的螺纹接合来固定。当锁定爪伸出时，下部固定楔被阻止纵向位移，从而抵抗施加在锚固滑块上的相反的设定力。锁定爪通过支撑杆保持在锁定位置，支杆由安装在封隔器心轴孔之一中的换档套筒可释放地阻挡。

摘要： An apparatus or tool for applying tension to a tubing string. The tool comprises a housing and a sleeve within the housing. One end of the housing is attached to the tubing string and the opposite end of the sleeve is attached to the tubing string. Hydraulic fluid pressure acts upon a piston carried by the sleeve to contract the sleeve relative to the housing and apply tension to the tubing string. The hydraulic tubing tensioner can be used to apply tension to tubing between two packers or to apply tension to a tubing string extending from a downhole packer to the well surface.

摘要： Methods of forming permeable sand screens in long, open hole well bores within fluid producing zones are provided. The methods basically comprise the steps of placing a perforated pipe in the open hole well bore, providing a hardenable composition which after being placed in a desired location cures into a hard mass, placing the hardenable composition in the well bore adjacent to the fluid producing zone within the interior of the perforated pipe therein, between the perforated pipe and the walls of the open hole well bore and within voids or fractures in the producing zone, causing the hardenable composition to cure into a hard permeable mass and drilling the hard permeable mass out of the interior of the perforated pipe.

摘要： There is a need to better understand well conditions during gravel pack completions and during production through a gravel pack. The sensors that are used to determine the conditions at the actual interface between the gravel pack and the production interval are located directly on the gravel pack assembly. This allows for the most accurate and timely understanding of the interface conditions. Sensors along the length of the gravel pack can provide real time bottom hole pressure and temperature readings. Other sensors could provide information on flow rate of fluids produced as well as density measurements. Thus, during completion, the sensors can provide information on the effectiveness of gravel placement. During production, the sensors could provide instantaneous information on dangerous well conditions in time to minimize damage to the well equipment.

摘要： A sintered metal screen is releasably suspended from a packer mandrel by a locking mandrel and a landing nipple. The sintered metal screen and locking mandrel are retrievable with the assistance of a running tool which is insertable into the bore of the locking mandrel. According to this arrangement, the sintered metal sand screen can be removed and replaced without retrieving the packer or the production tubing. In one embodiment, the sintered metal screen is enclosed within the bore of a sliding side valve. The sliding side valve can be opened and closed as desired for selectively admitting production from various producing zones, or for isolation of a damaged screen. In another embodiment, an auxiliary sintered metal screen is inserted into the bore of a primary screen, for example, a conventional wire-wrap sand screen. The sintered metal sand screen is thus interposed in the flow path for screening out sand fines which may be conducted through the wire-wrap screen because of screen damage caused by corrosion or sand erosion.
摘要翻译：烧结金属屏幕通过锁定心轴和着陆接头可释放地从封隔器心轴悬挂。烧结的金属丝网和锁定心轴可借助于可插入锁定心轴的孔中的运行工具来回收。根据这种布置，烧结金属砂筛网可以被取出并且不用取回封隔器或生产管道而被更换。在一个实施例中，烧结金属丝网封闭在滑动侧阀的孔内。可以根据需要打开和关闭滑动侧阀，以选择性地允许来自各个生产区的生产，或用于隔离损坏的筛网。在另一个实施例中，将辅助烧结金属屏幕插入主屏幕的孔中，例如常规的电线包裹砂筛。因此，烧结金属砂筛被插入在流路中，用于筛选由于腐蚀或砂土侵蚀引起的筛网损坏而可能通过线包裹丝网进行的细砂。
