    • A solar charger (100) for charging a power battery is provided, which includes: a photo-sensitive unit (101) configured to detect light intensity; a charging unit (103) configured to receive a voltage transformed from solar energy and to boost the voltage so as to supply the voltage to the power battery; a switch unit (102) coupled between the charging unit (103) and the power battery, and configured to disconnect the power battery from the charging unit (103) or connect the power battery with the charging unit (103); and a control unit (104) coupled to the photo-sensitive unit (101), the charging unit (103) and the switch unit (102) respectively, and configured to switch on the charging unit (103) and the switch unit (102) when the light intensity is higher than a first predetermined value so as to charge the power battery. The solar charger (100) can be used for high-power devices such as electric buses and vehicles.

    • A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.
    • 在没有环形空间隔离的开孔中进行压裂作业。 环形空间由位于隔离阀后面的伸缩构件跨越。 一组给定的伸缩构件可以不被覆盖,并且伸缩构件延伸以跨越环形空间并以密封方式接合地层。 加压压裂液可以泵送通过可伸缩通道,并且所需地层的部分断裂。 在适当的形成中,不需要固井来保持井身完整性。 伸缩构件可以可选地具有屏幕。 通常,地层的性质是不需要砾石填料。 生产线可以用伸缩装置插入弦中,并且可以通过选择性地暴露的伸缩构件来产生感兴趣的形成部分。
