摘要： An improved method and apparatus are provided for orienting a particular well completion in accordance with azimuths determined with respect to magnetic north. The invention permits the perforating gun of a wireline tool to be properly oriented in either a vertical or non-vertical wellbore. A wireline tool is described whose lower section contains a gun section and is rotatably joined to the upper section and may be rotated about a swivel joint assembly to move independently of the upper section and in accordance with an orienting means. The rotation may be accomplished by mechanical, hydraulic or electrical means of imparting rotation. In addition, preferred embodiments of the invention include a distant display such that operators may verify directional orientation of charges prior to initiating them. Alternative embodiments are provided for practicing the invention using multiple passes into the well which involve less risk of damage to portions of the well tool.

摘要： The present invention relates generally to a method and apparatus utilized in hydrocarbon exploration. More specifically, the present invention relates to the utilization of acoustic sources and receivers to determine acoustic properties of geologic formations as a logging tool traverses them, be it a wireline logging tool and/or a logging while drilling (LWD) tool. More particularly, the present invention is directed to methods of, and apparatus for, adaptive equalization of receivers to reduce and/or substantially eliminate sensitivity mismatch. A method is provided, the method comprising detecting arrival times of a first wave at each of a plurality of receivers, determining a first place in a well when the arrival times of the first wave are substantially the same at each of the plurality of receivers, and estimating effective receiver sensitivities and equalization factors for each of the plurality of receivers using a Stoneley wave amplitude received by the plurality of receivers at the first place in the well. The method also comprises correcting amplitudes of a second wave received by the plurality of receivers using the estimated effective receiver sensitivities and equalization factors for each of the plurality of receivers.
