FracPlane专利系统使用定射角射孔技术将裂缝起始点限定在近井筒的同一平面上。通过横向连接到裂缝平面,每个孔道都可为裂缝输送压裂流体,从而将井筒尺寸造成的差异最小化。
技术应用
1.限流射孔设计;
2.可采用电缆、钢丝和油管传输;
3.非常规油藏;
4.可用载体尺寸:3 1/8”和3 3/8”。

每簇射孔数确定后,每个FracPlane系统都将射孔孔眼设定在优选的裂缝方向上,平衡井眼上下方的过流面积。每个孔道都为压裂液提供流动通路,井眼可以通过每个孔道生产油气。
FracPlane使用CONNEX射孔弹作业效果更佳。生产的每批次CONNEX射孔弹均适用于压实储层,确保射开的孔道总是连通裂缝平面。
Connex反应射孔
无论岩石属于哪种类型,CONNEX反应射孔都可形成干净、畅通的孔道。每个孔道具有自洁功能,不受其他孔道影响,因此清洁孔道的比例更大,且可在未损坏的储层与井筒之间形成理想的流动通路。

上图可以清晰看到CONNEX提供的孔道几何形状和质量有明显改进。孔道周围没有更多的破碎区,没有压实的填充物,只形成一个宽阔、干净的通道。注意裂缝尖端,这是一个非常有利于油气流入的特征。
CONNEX产品可以采用标准硬件部署,射孔枪性能和井筒完整性不受影响。压实岩石的穿透力与GEODynamics业界领先的RAZOR射孔弹等效。
工作原理
GEODynamics的CONNEX射孔弹使用活性金属产生二次反应,以清除射孔区内的压实区。沿孔道分布的专利射孔弹衬套材料在遇到热和压力时会发生放热反应。该反应在孔道内和周围产生巨大的压力,将破碎区压实的碎片打碎并返排到井筒中。在合适的岩石中,孔道尖端也可形成裂缝。
系统优势
1.现场证实无需使用酸或大幅减少用酸量;
2.更高效的水力压裂作业(处理排量+压力);
3.更高效的限流射孔;
4.最大化修井效果;
5.使各向异性产层有利可图;
6.高性能注入井;
7.资产收益最大化;
8.多管柱应用。

孔道和尖端
干净的孔道和裂缝尖端?绝对是的。基质酸化和压裂作业的起始点最好在什么位置?CONNEX射孔弹可减少故障和压裂压力,提高作业排量,避免裂缝曲折,并最大限度地降低脱砂风险。
可用的射孔弹配置:2、3、4、5、6、7、8、10、12和14孔设计。该系统已经过优化,无需定方位下入。
什么是欠平衡
与传统的欠平衡射孔不同,CONNEX系统的有效性不依赖于岩石性质、井眼或地层压力。即使在各向异性最大的地层,每个孔道里的碎片也被独立清理排出。不再需要用于增强欠平衡的系统,使电缆射孔在大多数情况下成为经济实惠且有效的解决方案。
CONNEX产品可以采用标准硬件部署,射孔枪性能和井筒完整性不受影响。压实岩石的穿透力与GEODynamics业界领先的RAZOR射孔弹等效。

The patented FracPlane system uses angled perforations to place fracture initiation points on the same plane near wellbore. By connecting transversely to the fracture planes, every hole feeds the fracture, and variations due to hole size are minimized. For longitudinal fracture planes we recommend orienting your perforation clusters.
Shot configurations available: 2, 3, 4, 5, 6, 7, 8, 10, 12, and 14 shot designs. This system is optimized to be run without orientation.
APPLICATION
1.Limited Entry Perforating Design
2.Conveyable on Wireline, Braided Slickline, and Tubing Conveyed
3.Unconventional Reservoirs
4.Available Carrier sizes: 3 1/8” and 3 3/8”
Once the number of shots in a cluster is set, each FracPlane? system provides the best opportunity to place a perforation in the preferred fracture direction, and balances the flow area above and below the well. Each perforation feeds your frac, and the well can produce through each perf.
FracPlane、 works better with CONNEX charges. Every production run of CONNEX charges is qualified in stressed rock targets so that every tunnel connects to the frac plane, every time.
Connex Reactive Perforating
CONNEX、 Reactive Perforating delivers clean, open tunnels independent of rock type. Every tunnel receives its own cleaning action, independent of other perforations, resulting in a much greater percentage of clean tunnels and ideal flow path between undamaged reservoir and the wellbore.
CONNEX products deploy in standard hardware. Gun performance and wellbore integrity are unaffected. Penetration into stressed rock is equivalent to GEODynamics’ industry-leading RAZOR? charges.
HOW IT WORKS
GEODynamics’ CONNEX charges use reactive metals create a secondary reaction to clear out the compaction zone in a perforating zone. Patented charge liner material deposited along the tunnel reacts exothermically when introduced to heat and pressure. This reaction creates significant pressure within and around the tunnel, breaking up and expelling the crushed zone compacted debris back into the well bore. In sufficiently competent rock, fractures are also formed at the tunnel tip.
SYSTEM ADVANTAGES
1. Field proven to Eliminate or Dramatically Reduce Acid Volumes
2. More Efficient Hydraulic Fracture Stimulation (treating rates + pressures)
3. More Efficient Limited Entry Perforation
4. Maximum Impact Workovers
5. Profitable Completion of Heterogeneous Pay Zones
6. High Performance Injection Wells
7. Maximum Return from Mature Assets
8. Multi-String Applications
TUNNELS AND TIPS
Clean tunnels and fractured tips Absolutely. What better place to initiate an acid matrix or fracture stimulation CONNEX charges reduce breakdown and treating pressures, improve treating rates, eliminate tortuosity, and minimize the risk of screen-outs.
WHAT UNDERBALANCE
Unlike traditional underbalanced perforating, the effectiveness of CONNEX? systems is not dependent on rock properties, wellbore or formation pressures. Debris is expelled independently from every tunnel, even across the most heterogeneous intervals. Systems designed to enhance underbalance are no longer required, making wireline perforating an affordable and effective solution in most cases.
NO RISK… ALL REWARD
CONNEX? products deploy in standard hardware. Gun performance and wellbore integrity are unaffected. Penetration into stressed rock is equivalent to GEODynamics’ industry-leading RAZOR charges.
