摘要： A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.

摘要： A hydraulic time delay system and method in a wellbore tool is disclosed. The system/method includes an actuation mechanism which allows pressure to act on a functional piston in the wellbore tool. The movement of the piston is restrained by a partially or filled reservoir which is allowed to exhaust through a flow restriction element. The restriction element comprises standard metal tubing with a known inner diameter and is cut to an exact length as predicted by fluid dynamic modeling. A time delay and rate of piston movement desired for the downhole tool, between a trigger event such as pressure and a functional event, can be tuned with parameters that include the length and diameter of the tubing, reservoir fluid viscosity and number of tubes in parallel. In another embodiment, a secondary plugging element added to the reservoir controls the rate of piston movement and time delay.

摘要： A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The RPE includes a first composition and a second composition that changes phase or strength under wellbore conditions. After a stage is perforated, RPEs are deployed to isolate toe ward pressure communication. The second composition changes phase to create flow channels in the RPE during production. In an alternate system/method, the second composition changes phase or strength thereby deforming the RPE to reduce size and pass through the RSM's. The RPEs are removed or left behind prior to initiating well production without the need for a milling procedure.

摘要： A perforating short gun for use in a horizontal well casing. The gun includes a gun carrier and a charge holder to carry shaped charges. The charge holder is inserted into the gun carrier and a selected length of the gun carrier includes internal features created therein to a depth in an inside wall of the gun carrier. The internal features are located and configured to align with a shaped charge, creating a standoff between the shaped charge and the internal feature such that when the charge is detonated it creates an opening through the internal feature.

摘要翻译：公开了一种用于定位插塞以隔离水平，垂直或偏离井筒中的断裂带的井筒塞隔离系统和方法。系统/方法包括横向钻入烃地层的井眼套管，设置大内径（ID）限制套筒构件（RSM）的井筒设定工具（WST）和限制塞块元件（RPE））。 WST与RSM一起定位在所需的井眼位置。在WST设置和密封RSM之后，在RSM中形成一个符合要求的座面（CSS）。 CSS被设计成接合/接收部署到井筒套管中的RPE。接合/就座的RPE隔离了RSM的脚跟区和脚趾病房流体通信，以创建骨折区。在开始生产之前，RPE被移除或留下，而不需要铣削程序。大量的RSM减少了石油生产过程中的流量收缩。

摘要： A perforating gun for use in a well casing, the gun having a gun carrier extending along a longitudinal axis; plural shaped charges located inside the gun carrier, in a plurality of groups, a first group being positioned in a first single plane, transverse to the longitudinal axis, and a second group being positioned in a second single plane, transverse to the longitudinal axis. The first and second groups of charges are spaced along the longitudinal axis so that a third single plane, transverse to the longitudinal axis, intersects each of the shaped charges of the first and second groups of charges.
