摘要： An apparatus and method for determining formation resistivity at a plurality of radial distances from an earth borehole uses a single receiver pair and a plurality of electromagnetic energy transmitters sequentially spaced along the apparatus from the receiver pair, such transmitters being sequentially pulsed at approximately 1-2 MHz each to provide time separation between the pulsing of the plurality of transmitters. The closest spaced transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of the closest transmitter essentially independent of formation resistivity. Alternatively, a single transmitter is spaced a predetermined distance from the closer receiver to make the depth of investigation of such transmitter essentially independent of formation resistivity.

摘要： Methods and apparatus for detecting the approach of a boundary stratum while drilling in a substantially horizontal subsurface zone using sensor tools having sensors with different depths of investigation. The two depths of investigation signals are used to reduce spurious signals. In some cases, dips or angles of the boundary strat with the borehole may be determined. In alternative embodiments, one or more electromagnetic energy transmitters are used with a single receiver pair to generate a characteristic signature of approaching boundary stratum.

摘要： A method for improving ROP and reducing hazards in drilling subterranean wells by using an acoustical system 15 to look ahead of the drill bit 14, detects and analyzes geologic features ahead of the bit 14 which may be qualified as drilling hazards 17. Detection of such hazards 17 may facilitate use of more aggressively penetrating bits 14 such as PDC bits as opposed to roller cone bits. In addition, other drilling parameters may be adjusted to improve ROP due to the ability to timely respond to identified hazards 17 before they may be detrimentally encountered by the bit 14. The acoustic system 15 may look ahead of the bit 14 by at least 100 meters, using propagated acoustic waves 19 to locate changes in acoustic impedance which may represent drilling hazards 17. In addition, bulk resistivity ahead of the bit 14 may also be measured and used to locate drilling hazards 17. The measured properties of the investigated formation may facilitate optimizing the design and operation of a drilling program so as to improve the rate of penetration.
摘要翻译：通过使用声学系统15向前看钻头14来改善钻井地下井中的ROP并减少危害的方法，检测并分析钻头14之前的地质特征，这可以被认定为钻井危险17.检测这种危险 17可以有助于使用更积极地穿透的位14，例如PDC位而不是辊锥位。此外，可以调整其他钻孔参数以改善ROP，这是由于在它们可能不利地被钻头14遇到之前及时响应所识别的危险17的能力。声学系统15可以将钻头14向前看至少100米使用传播的声波19来定位可能代表钻井危险的声阻抗的变化17.此外，钻头14之前的体电阻率也可以被测量并用于定位钻井危险17.所研究的地层的测量特性可以有利于优化钻井计划的设计和运行，以提高渗透率。

摘要： A borehole may be drilled utilizing the bottom hole assembly 10, 50 with a downhole motor 14, 110, which may offset at a selected bend angle. A bend for directional drilling may be provided by a PDM, or by a RSD. A gauge section 36 secured to the pilot bit 18 has a uniform diameter bearing surface along an axial length of at least 60% of the pilot bit diameter. The bit or reamer 16 has a bit face defining the cutting diameter of the drilled hole. The axial spacing between the bend and the bit face is controlled to less than fifteen times the bit diameter. The downhole motor, pilot bit and bit may be retrieved from the well while leaving the casing string in the well.
