摘要： The disclosure describes enhanced determination of dip and strike/azimuth for real-time MCI data processing in some difficult conditions such as low-dip and low-anisotropy formations using formation properties from surrounding layers. The method is effective for the enhanced determination of dip and azimuth to enhance the inversion accuracy of formation dip and azimuth if the formation anisotropic ratio is low and so reduce the uncertainty of the inverted dip and azimuth.

摘要： A wireline device for use in downhole operations may comprise at least one of a position indicator arrangement, a latch arrangement and a seal arrangement. The position indicator device may alert a winch line operator of the approach of a downhole toolstring to a stuffing box located at the wellhead of an oil or gas well. This may permit the winch line operator to control winching of the wireline so as to avoid retraction of the toolstring into engagement with the stuffing box thereby minimising the resulting risk of wireline breakage. The latch arrangement may retain the tool string relative to a wellhead housing so as to avoid the toolstring dropping back into the wellbore in the event of wireline breakage. The seal arrangement may prevent a hydrocarbon leak from the wellbore to an environment external to the wellhead housing in the event of wireline breakage.
摘要翻译：用于井下操作的有线装置可以包括位置指示器装置，闩锁装置和密封装置中的至少一个。位置指示装置可以提醒绞车线操作者将井下工具串进入位于油井或井口井口处的填料箱。这可以允许绞车线操作者控制电缆的绞线，以避免工具串缩回到与填料函接合，从而最小化导致电线断线的风险。闩锁装置可以相对于井口壳体保持工具串，以避免在有线断裂的情况下工具串落回到井筒中。在电缆断裂的情况下，密封装置可以防止烃从井眼泄漏到井口壳体外部的环境。

摘要： In one example of rotational ranging in a wellbore in which a wellbore component having an axis of rotation is disposed, a wellbore ranging sensor is disposed on a circumferential area surrounding the axis of rotation. The sensor is moved on the circumferential area to multiple distinct sensing positions. At each sensing position, a magnetic field from another wellbore that is apart from the wellbore is measured resulting in multiple magnetic field measurements at the multiple distinct sensing positions. The multiple magnetic field measurements are provided to determine a position of the wellbore relative to the other wellbore using at least a subset of the multiple magnetic field measurements.
