FracPlane專利系統使用定射角射孔技術將裂縫起始點限定在近井筒的同一平面上。通過橫向連接到裂縫平面,每個孔道都可為裂縫輸送壓裂流體,從而將井筒尺寸造成的差異最小化。
技術應用
1.限流射孔設計;
2.可采用電纜、鋼絲和油管傳輸;
3.非常規油藏;
4.可用載體尺寸:3 1/8”和3 3/8”。

每簇射孔數確定后,每個FracPlane系統都將射孔孔眼設定在優選的裂縫方向上,平衡井眼上下方的過流面積。每個孔道都為壓裂液提供流動通路,井眼可以通過每個孔道生產油氣。
FracPlane使用CONNEX射孔彈作業效果更佳。生產的每批次CONNEX射孔彈均適用于壓實儲層,確保射開的孔道總是連通裂縫平面。
Connex反應射孔
無論巖石屬于哪種類型,CONNEX反應射孔都可形成干凈、暢通的孔道。每個孔道具有自潔功能,不受其他孔道影響,因此清潔孔道的比例更大,且可在未損壞的儲層與井筒之間形成理想的流動通路。

上圖可以清晰看到CONNEX提供的孔道幾何形狀和質量有明顯改進??椎乐車鷽]有更多的破碎區,沒有壓實的填充物,只形成一個寬闊、干凈的通道。注意裂縫尖端,這是一個非常有利于油氣流入的特征。
CONNEX產品可以采用標準硬件部署,射孔槍性能和井筒完整性不受影響。壓實巖石的穿透力與GEODynamics業界領先的RAZOR射孔彈等效。
工作原理
GEODynamics的CONNEX射孔彈使用活性金屬產生二次反應,以清除射孔區內的壓實區。沿孔道分布的專利射孔彈襯套材料在遇到熱和壓力時會發生放熱反應。該反應在孔道內和周圍產生巨大的壓力,將破碎區壓實的碎片打碎并返排到井筒中。在合適的巖石中,孔道尖端也可形成裂縫。
系統優勢
1.現場證實無需使用酸或大幅減少用酸量;
2.更高效的水力壓裂作業(處理排量+壓力);
3.更高效的限流射孔;
4.最大化修井效果;
5.使各向異性產層有利可圖;
6.高性能注入井;
7.資產收益最大化;
8.多管柱應用。

孔道和尖端
干凈的孔道和裂縫尖端?絕對是的?;|酸化和壓裂作業的起始點最好在什么位置?CONNEX射孔彈可減少故障和壓裂壓力,提高作業排量,避免裂縫曲折,并最大限度地降低脫砂風險。
可用的射孔彈配置:2、3、4、5、6、7、8、10、12和14孔設計。該系統已經過優化,無需定方位下入。
什么是欠平衡
與傳統的欠平衡射孔不同,CONNEX系統的有效性不依賴于巖石性質、井眼或地層壓力。即使在各向異性最大的地層,每個孔道里的碎片也被獨立清理排出。不再需要用于增強欠平衡的系統,使電纜射孔在大多數情況下成為經濟實惠且有效的解決方案。
CONNEX產品可以采用標準硬件部署,射孔槍性能和井筒完整性不受影響。壓實巖石的穿透力與GEODynamics業界領先的RAZOR射孔彈等效。

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.
