国外页岩气水力压裂技术及工具一览页岩储层具有超低孔低渗特性,钻完井后需要压裂改造后才得到经济产量。
国外油田服务公司最新工具达到了很高水平,水平井裸眼封隔器投球滑套分段压裂技术用高强度低密度球级差达到1/16in,封隔器耐压差达到70MPa,TAM公司自膨胀封隔器最高可达302 °C ;泵送桥塞射孔分段压裂技术所用桥塞可分为:堵塞式、单流阀式和投球式复合桥塞,桥塞耐压差达103.4MPa,耐温232 °C ;哈里伯顿CobraMax H连续油管喷射工具系统,目前最多达到44段。
这些为国内页岩气水力压裂完井方式与压裂工具的选用打下基础。
从应用工具角度看,分段压裂工艺方面主要包括:水平井裸眼封隔器投球滑套分段压裂技术,泵送桥塞分段压裂技术,水力喷射分段压裂技术。
从压裂工具方面分析,目前页岩气压裂技术有可膨胀封隔器/裸眼封隔器+滑套多级压裂,泵送桥塞射孔压裂联作多级压裂,水力喷射压裂等。
在美国的页岩气开发技术中,可膨胀封隔器/裸眼封隔器+滑套多级压裂,泵送桥塞射孔压裂联作多级压裂技术比较成熟,使用比较广泛,可适用于较长的水平段;水力喷射压裂可实现准确定位喷射,无需机械封隔,节省作业时间,非常适合用于裸眼井、筛管井以及套管中井。
1、水平井裸眼封隔器投球滑套多级压裂系统封隔器投球滑套多级压裂技术一般采用可膨胀封隔器或者裸眼封隔器分段封隔。
根据页岩气储层开发的需要,使用封隔器将水平井段分隔成若干段,水力压裂施工时水平段最趾端滑套为压力开启式滑套,其它滑套通过投球打开,从水平段趾端第二级开始逐级投球,进行有针对性的压裂施工。
水平裸眼井多级压裂目前已经是北美页岩气压裂开采主要技术手段,并越来越受到作业者的欢迎。
水平井多级压裂技术关键在于封隔器(压裂封隔器和可膨胀封隔器)和滑套可靠性和安全性能,尤其是管外封压裂管柱的可膨胀封隔器和开启滑套的高强度低密度球材料决定技术的成功与否。
目前国外油田服务公司都有自己成熟的工具,高强度低密度球级差达到1/16in,封隔器耐压差达到70MPa,TAM公司耐高温自膨胀封隔器最高可达30 °C 。

通用脉冲器主要由主阀组件和驱动组件构成,可以适用于涡轮发电机系统(UP-UPU或UPA)或者NaviTrak电池系统(UPB),两者都需要配备已替代了NaviTrak PDM脉冲系统的励磁驱动电路模块。
当使用NaviTrak185 MWD系统时,不需要包含了主模块、驱动模块、振动侦测设备的励磁驱动电路模块。
1.2工作原理通用脉冲器在井下工作时有三种状态,即正常打开(待命)、驱动组件加电(先导阀关闭)和驱动组件断电(先导阀打开)状态。
1.2.1通用脉冲器正常打开(待命):钻井液通过钻柱向下到达主阀组件,在主阀组件,一部分流体通过进口的筛屏转入主阀体内,其余的流体从限流环和主阀体(主阀头)之间空隙通过。
一部分流体通过进口的筛屏转入主阀体内,因此,流经主阀体内的流体的速度取决于限流环的过流面积。
流入主阀体内的流体向下到达先导阀座,从驱动组件波纹管罩上6个泄流孔流出。
1.2.2驱动组件加电(先导阀关闭)当励磁驱动电路给驱动组件线圈供电时,驱动组件铁芯在电磁力作用下与线圈极板吸合,使得驱动轴和先导阀伸出,驱动组件的电磁力不是线性的,当铁芯接近线圈极板时,电磁力显著增大。
这种成倍增大的力是克服先导阀趋近于截断先导阀座的流体产生的阻力所必需的。
当流体被截止时,主阀体内的压力几乎瞬间增大,使得主阀体内部和主阀体外部主阀头下方区域产生了很高的压差。
连续油管作业技术简述1.连续油管简述连续油管(coiled tubing,简称 CT) 装置是一种有别于传统作业方式的特种作业设备, 自上世纪 60年代初引入油田生产后,便以其高效、实用、经济的特点倍受使用者的青睐。
连续管也称柔性管,是一种强度高、塑性好、抗腐蚀较强的 ERW 焊接钢管,单根长度可达几千米,在生产线连续生产并按一定长度缠绕在卷筒上交付使用。
进入 2000 年后, 由于材质和设备制造技术的更新提高, 连续油管技术发展迅速,新型连续油管车各方面性能大为改进, 能够适应更加恶劣环境和从事更为复杂的技术。
2.连续油管设备组成连续油管设备主要包括以下几部分:(1)滚筒:储存和传送连续油管;(2)注入头:为起下连续油管提供动力;(3)操作室:设备操作手在此监测和控制连续油管;(4)动力组:操作连续油管设备所要求的液压力源;(5)井控装置:连续油管带压作业时的井口安全装置。
3.连续油管工作原理其工作原理是:车辆停靠井口处,依次吊装防喷器、注入头于井口(防喷管)上,将 CT 从绞盘上拉出经鹅颈管导向进入注入头, 由注入头链条拉紧后通过防喷器下入作业管柱中, 绞盘轴端的接头可与配套设备联接, 泵注液体或气体入井, 操作室内可远程控制 CT 起下及相关部件的动作。
4.连续油管技术的应用连续油管以其高效性、经济性以及对地层污染小等优点目前已广泛应用于钻井、完井、采油、修井和集输等各个作业领域,被称作“万能作业机”。
4.1连续油管的冲砂洗井冲砂洗井是目前最常见的连续油管修井作业。
洗井是将洗井液通过连续油管泵入井内, 使砂粒松动并将其从生产油管与连续油管的环空冲到地面上来。
连续油管由于其具有良好的挠性等特点,除进行常规的冲洗作业外,还用于解决一些比较复杂的井下管柱被卡堵情况。
这类井既无法建立循环又不能起出井下管柱,常规方法处理起来难度大。
连续油管冲砂技术可以在不压井的情况下进行快捷作业,效率高,直径小,非常适合油管作业,还可以避免因压井而产生的地层损害。
Mini-beta防砂作业流程及安全风险分析一、地层出砂危害及防砂作业的目的出砂危害:油、气井出砂如果得不到治理,就会越来越严重,致使出砂油、气井不能有效的开发。
出砂的危害主要表现在以下三个方面:(1)减产或停产作业;(2)地面和井下设备磨蚀;(3)套管损坏、油井报废,所以要进行防砂作业。
防砂目的:延长井的生产寿命;保护地面设施;降低生产井的维修费用。
二、防砂作业步骤及注意事项1、作业工具准备作业前首先需要知道井的基本数据,包括套管磅级、射孔数据、筛盲管扣型等,根据不同井的情况准备手工具和各种变扣接头。
手工具一般包括:管钳、卷尺、航空剪刀、筛规、安全卡瓦、提丝、裁纸刀、内径规、外径规、钢丝刷、锉等。
各种变扣接头主要包括:筛盲管防喷变扣(根据筛盲管尺寸定),冲管防喷变扣、座封工具与钻杆连接的变扣(视作业平台钻杆尺寸决定,7”井座封工具上部接头扣型为 2-7/8”IFB;9-5/8”井座封工具上部接头扣型为3-1/2”IFB)、循环头、试压堵头等。
2、作业流程(以一次2层9-5/8”防砂井为例)2.1、电缆座封沉砂封隔器工具组合:Baker "F-1" 沉砂封隔器 + 电缆座封工具+ CCL + 马龙头 + 电缆沉砂封隔器的坐封位置要参照测井曲线避开套管接箍。
沉砂封隔器应坐封于底层射孔段底部以下大约5~8ft处。
注意事项:电缆下入"F-1"沉砂封隔器时,关闭全船无线电通讯,停止一切电弧焊作业,平台所有人员禁止使用手机。
如果电缆坐封"F-1"沉砂封隔器有困难,可用钻杆下入液压座封工具。
钻杆下入液压座封工具步骤为:1)工具组合为:"F-1"封隔器+液压坐封工具 + 变扣 + 3-1/2"钻杆(具体柱数根据同位素的深度来定)+ 同位素接头(3-1/2" IF B ×P) + 3-1/2"钻杆。
Rotary steerable systems should deliver smooth, precise, fast drilling.Unfortunately, too many don’t…Get the superior performance you expectAutoTrak rotary steerable systemsand it's because they don't deliver on a rotary steerable's full potential.When you choose a rotary steerable system, you expect it to deliver:•a smooth, in-gauge hole•a precisely placed wellbore and fast, reliable drilling operations.Because efficiently drilling a smooth wellbore and precisely placingit in the most productive zones helps you keep costs down while enhancing your production.But most rotary steerable systems aren’t that smooth… or very precise. And you may not even know it, because instead of talking about these problems...debating the relative merits of “push-the-bit” steering versus “point-the-bit” steering. Or vice-versa.too many service providers waste your time These debates miss the point.Neither technique can consistently deliver the premium performance you need because both use a “pseudo steering” approach.pseu•do steering PUSH-THE-BIT“Push-the-bit” systems use steering pads that deflect against the wellbore in an on/off cycle that creates doglegs and an angular wellbore.POINT-THE-BIT “Point-the-bit” systems use a BHA with a fixed tilt which causes hole spiraling and a consistently over-gauge wellbore.attempting to steer with a fixed-tilt BHA or on/off pad cyclesPseudo-steering can’t consistently deliver the superior rotary steerable performance you need.High local doglegs. But it does deliver some things with consistency.And, because most systems that use pseudo-steering also restrict bit selection and flow rates, they artificially limit ROP and overall performance.That won’t deliver the results you need. Instead, you get higher well construction costs and lost production.One that delivers the quality wellbore and drilling performance you expect.There’s a better approachCONTINUOUS PROPORTIONAL STEERING Over-gauge wells.Hole spiraling. Angular wellbores.When you steer with precision-controlled pads that maintain a continuous proportional steering vector, you get superior control and a quality wellbore.And when you have the flexibility to optimize the system for the application, you get faster, more reliable drilling performance.AutoTrak systems are the only ones that use continuous proportional steering.REDUCE WELL CONSTRUCTION COSTS WITHUNSURPASSED HOLE QUALITY EXACT WELL PLACEMENTENHANCE PRODUCTION WITH FASTER, MORE RELIABLE PERFORMANCE WITH OPTIMIZED DRILLINGand completion runs.And because holes stay in-gauge, you collecthigh-quality FE data to optimize drilling, placement, and reserve estimation. In-gauge holes also minimizecuttings and maximize hole cleaning velocity.ENHANCE PRODUCTION WITH EXACT WELL PLACEMENTUsing continuous proportional steering, AutoTraksystems check azimuth and inclination everymillisecond and automatically adjust steer forcessecond-by-second for precise control.Using real-time formation evaluation, coursecorrections can be implemented with ease—adjusting the AutoTrak system’s well path withsmooth precision to keep you on target throughall formation types.The result: maximized reservoir exposure andenhanced recovery.GET FASTER, MORE RELIABLE PERFORMANCE WITH OPTIMIZED DRILLINGBecause AutoTrak systems use internal hydraulicsto power independent ribs mounted on adecoupled, slowly rotating sleeve, their steeringcontrol is not affected by drilling dynamics.As a result, the systems operate independentlyof bit pressures, flow rates and drilling fluidproperties—allowing you to optimize your bitand program design to formation challengesas opposed to competitive rotary steerableswhich often restrict BHA design and bit selection.Continuous proportional steering also providesenormous versatility and reliability in allformation types—from soft to hard—allowing you todrill the vertical, curve, and lateral in a single run.CLICK OR TAP THE TABS BELOW TO LEARN MOREA customer in the Middle East wanted to test available rotary steerable system technologies to establish which provided the best hole quality. The customer compared data from over 700 wells to isolate the effectiveness of the three types of rotary steerable system (RSS) technologies—push-the-bit systems, point-the-bit systems, and the only continuous proportional steering system on the market, the AutoTrak RSS .Results overwhelmingly concluded that using continuous proportional steering reduced tortuosity by magnitudes of 4 to 6 times when compared to push-the-bit and point-the-bit RSS methods. The AutoTrak RSS consistently delivered better hole quality in horizontal drilling.That translates into fewer stuck pipe incidents, less chance of encountering problems during completion installation, and greater production potential in both the short- and long-term.MIDDLE EASTMEASURED DEPTH (FT)W E L L B O R E I N C L I N A T I O N (D E G )Point the Bit Push the Bit Continuous Proportional Steering 93.592.591.590.589.588.587.586.585.584.583.58,5008,7008,9009,1009,3009,5009,7009,90010,10010,300Comparison of well tortuosity from the study using high resolution wireline surveys from three offset wells.

Torsional stick-slip and high wear-and-tear on drilling equipment were expected. Working with Baker Hughes, the client chose the new 4¾ in. AutoTrak eXact system because its steering capabilities best matched the operational requirements.Despite the challenging conditions and highly-deviated well path, the system set three new records and saved 1.5 days compared to a previous record-setting run.
