国外页岩气水力压裂技术及工具一览

国外页岩气水力压裂技术及工具一览

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 。

贝克休斯Autotrak旋转导向系统介绍

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. The difference is unmistakable when comparing wells drilled with push-the-bit (yellow), point-the-bit (orange), and continuous proportional steering (green) technologies. The AutoTrak RSS clearly delivers substantially superior hole quality.UNSURPASSED HOLE QUALITYREAD THE FULL CASE STUDY EXACT WELL PLACEMENT OPTIMIZED DRILLINGCLICK OR TAP THE TABS BELOW TO LEARN MORE EXACT WELL PLACEMENTAn operator needed to drill a challenging well profile thatincluded a BUR of 5.8°/100 ft (30 m) and a turn rate of up to7°/100 ft (30 m), including two ESP tangent sections.The operator previously experienced steering issues inoffset wells due to the stick-slip-inducing chalk. Theoperator also required precise control to ensure exact linerplacement and avoid nearby wells in the congested field.Baker Hughes used a 6¾ in. AutoTrak eXact system withcontinuous proportional steering to execute the complexdirectional plan (a total azimuthal turn >370° was achievedwhile building from 23° to 91° inclination) with no stick-slipissues in 166 hours.UK CONTINENTAL SHELFUsing continuous proportional steering, an AutoTrak eXact system efficiently drilled a complex,corkscrew-shaped well profile that required a long turn of >370° while building from 23°-91°.READ THE FULL CASE STUDYOPTIMIZED DRILLING UNSURPASSED HOLE QUALITY11OPTIMIZED DRILLING An operator needed to drill an extended-reach lateral totaling 21,548 ft MD, targeting two different layers in a field containing hard and abrasive sands. 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. The AutoTrak eXact system used continuous proportional steering to:• Drill up to 5% faster than the best offset• Extend the average run length by up to 15%• Achieve 7,296 ft of pay zone exposure MIDDLE EAST CLICK OR TAP THE TABS BELOW TO LEARN MOREThese operators got the performance they needed from their RSS New field re cords f or ROP and r un le ngth with AutoTrak eXact Previous ROP record (competitor RSS)Previous run length record (competitor RSS)AutoTrak eXact ROP on same deployment 05811141720500100015002000RUN LENGTH (FT)A V E R A G E R A T E O F P E N E T R A T I O N (F T /H R )2500Using an AutoTrak eXact system, an operator in the Middle East set three new records while drilling a highly deviated well path through a challenging formation.READ THE FULL CASE STUDYUNSURPASSED HOLE QUALITYEXACT WELL PLACEMENTGet the superior drilling performance you deserve.
