超高温陈化釜

Ⅰ.介绍Introduction

•Somedrillingfluids, especiallylime-treated drillingfluids thicken orsolidifywhen left in adeep hot holeunderstatic conditions. This thickeningimpairs and sometimes prevents drillingandcompletion operations, such as loggingand perforating. Chuangmeng’s HighTemperatureAgingCells aredesignedforuseinaging tests which help predict theperformanceofadrillingfluid understatic, high temperature conditions. Recent drillingresearch indicates that it is betterto apply pressurebeforeheatingsamples to elevated temperatures in agingtests. The pressure of nitrogen or carbon dioxide before the test is used to prevent the boiling and evaporation of the aging kettle at the temperature of the test.

•A 500ml aging kettle with a temperature of up to 600oF (316oC), a maximum experimental pressure of 2000 psi (13790KPa), and a maximum pressure of 3000 psi (20685 KPa) on the kettle body. The kettle chamber has sufficient expansion space to accommodate 350 milliliters of sample. Samples aged in the kettle can undergo shear tests.

•Cell assemblies madeof Type 304and Type 316 stainless steel and othercorrosion-resistant materials can bepressurized usingtheFann High Temperature.

•有些钻井液，特别是用石灰处理过的钻井液，在静态条件下，留在深热孔时会增厚或凝固。这种增厚会影响钻井和完井作业，例如测井和射孔。高温条件下，创梦公司的的高温陈化釜用于老化测试，能帮助预测静态下的钻井液性能。近期的钻探研究表明，在老化试验之前，最好是在高温前进行加压。在试验前用氮气或二氧化碳加压可以防止陈化釜在达到试验温度时沸腾和蒸发。

•500毫升陈化釜，温度可达600oF (316oC)，实验最高压力2000 psi（13790KPa）,釜体最高承压3000psi（20685 KPa）。釜腔有足够的膨胀空间，可以容纳350毫升的样品。釜中老化的样品可以进行剪切试验。

•釜的组件由304型和316型不锈钢等耐腐蚀材料制作，可以用于高温高压试验。

Ⅱ.安全Safety

•Safelaboratorypracticesand procedures should beobserved whileoperatingand maintainingtheHigh TemperatureAgingCell.

•Safelyoperatingthis agingrequiresyourunderstandingand practicingcorrect assemblyand useoftheaging cell, as well as theoven used to heat them.

•The aging cell and the oven are hot during operation. The operator should be aware of the hot areas and avoid contact with them. Burns can result from touching hot parts of the equipment during normal operation.

•The followingsections list someprecautions forsafelyoperatingand maintaining theseagingcells.

•在使用和维护高温陈化釜时，应遵守安全的实验室惯例和程序。

•安全运行老化，需要你对正确装配的理解、实践、和使用陈化釜，以及用于加热它们的烘炉。

•陈化釜和滚子炉在运行过程中很热。操作人员应注意加热区域，避免与他们接触。在试验过程中，接触设备的发热部位会导致烧伤。

•下面的部分列出了安全操作和维护陈化釜的一些注意事项。

2.1安全加压Safe Pressurization

•Some agingcells aredesigned to bepressurized beforeheat is applied to prevent boilingthesamplewhenheated.

•Always use eithernitrogen or carbon dioxide.

•Neverconnect the aging cell to compressed oxygen orothernon- recommended or flammablegas.

•Ifnitrogen is used, it must besupplied in an approved nitrogengas cylinder, orthenitrogen supplysystem must bebuilt into thelaboratory.Nitrogen cylinders must besecured to meet all safetystandards.

•Carbon dioxideis usuallysupplied in small cartridgeswhich contain approximately900 psig(6205 kPa)pressure. These cartridges areprimarily used in the field.

•DoNOTallowthecarbondioxidecartridgestobeheatedor exposed tofire.Theycanexplodeifoverheated.

•Maintain pressureregulators in good condition.

•Neveruseoil on pressureregulators.

•Leakingpressurization systems should berepaired or replaced.

•Gauges, fittingsand hoses should bekept in goodcondition and leaks should be found and corrected.

•Periodicallytest thesafetyreliefvalves on thepressurization manifolds to verifythat theywill relieve excessivepressure. Neverplugorbypass these safetyvalves.

•When pressurizingtheagingcell, always open thesupplypressure first, and then adjust the regulator.Do not attempt to pressurizehigherthan the equipment’s pressure ratingorthereliefvalvesettings.

•When de-pressurizing, shut offthesupplypressure, and bleed pressurefrom thesystem. Then, turn the regulatorT-screw counterclockwise(left).

•不要让二氧化碳罐受热或暴露在火中。如果过热，它们会爆炸。

•保持压力调节器处于良好状态。

•不要在压力调节器上使用机油。

•泄压系统应定期检修或更换。

•仪表、配件和软管应保持良好状态,如发现泄漏应及时维修。

•定期测试增压管上的安全泄压阀，以确认它们能释放过多的压力。永远不要堵塞或绕过这些安全阀。

•当对陈化釜加压时，首先打开供应压力，然后调节调节器。不要将压力设置到高于设备的额定压力或超过安全阀设定压力。

•一些陈化试验为防止加热时使样品沸腾，在加热之前加压。

•使用氮气或二氧化碳。

•切勿将可燃性气体例如压缩氧,注入陈化釜内。

•如果使用氮气，必须用合格供应商提供的氮气钢瓶，或者将氮气供应系统安装到实验室中。氮气钢瓶必须确保符合所有的安全标准。

•二氧化碳气弹通常提供压力是约900 psig（6205 kPa）, 这些小气弹主要是应用在现场。

•当减压时，关闭压力源压力，排放管路压力。然后，T螺杆逆时针转动调节器。

2.2加热安全SafeHeating

•When the temperature of the sample is lower than 200oF (93oC), the aging cell can be safely opened.

•Caution should be exercised when operatingovens to avoid accidental injurybytouchingtheinsideoftheoven orthecell assemblywhilethese arehot.  Theoven andcells arestill dangerouslyhot even afterthetest has ended and theoven has been turned off.

•It is not recommended that theagingcells beremoved from theheating chamberoroven until theyhavecooled to atemperaturein which theycan besafelyhandled.

•Coolingahot agingcellunder runningwateris verydangerous. This practiceis not recommended becausethereis risk ofgettingburned.Ifthe cell must be cooled quickly, beextremelycareful and wearappropriatehand protection.

•Use extreme caution when placing ahot cell in water. Hot steam that is generated when thewater contacts thehot cell cancausesevereburns.

•当陈化釜样品的温度低于200oF (93oC)，时才可以安全地打开陈化釜。

•  操作滚子炉时要小心，以避免接触滚子炉内部或陈化釜组件的意外烫伤，因为是高温的。即使试验结束，滚子炉已经关闭，滚子炉和陈化釜仍处于高温危险状态。

• 在陈化釜没有冷却到安全温度前，不建议将它们从加热室或滚子炉中取出。

•用流动的水冷却陈化釜是非常危险的。这种做法是不推荐的，因为有烧伤的危险。如果陈化釜必须迅速冷却，要特别小心，并穿戴适当的护具。

•在水中放置热釜时要特别小心。当水接触热釜时产生的热蒸汽会导致严重烧伤。

2.3安全操作（滚子炉）Safe ElectricalOperation (oven)

•Alwaysdisconnect thepowercablebeforerepairinganoven.

•Makesuretheelectrical sourceis fusedandgrounded. Verifythepowercord on theoven is ingood condition and has thepropergroundconnection.

•Electrical problems in theoven wiringorheatersmaynot beobvious by lookingat the equipment.

•修理滚子炉前要断开电源线。

•确保总电源的保险和接地。确认滚子炉上的电源线状况良好，并有正确的接地连接。

•通过查看设备，是看不到滚子炉电路或加热器的电气问题的。

•Ifanyofthesesituations occur, then thereis amalfunction and the equipment mayneed electricalrepair:

•Blows fuses ortrips thebreaker.

•Theheatingtimeseems too long.

•Thethermostat control does not repeat.

•如果出现这些故障，设备需要电气修理：

保险丝烧断或断路器跳闸。

加热时间过长。

温控器不运行。

2.4安全测试釜维护SafeTest CellMaintenance
