Abstract: The present invention is directed to a downhole, high-current, low-impedance, feed-through connector for passing electrical current, preferably high frequency AC current, between a tool compartment having relatively high pressure and another tool compartment having relatively low pressure. The primary intended application of the present invention is to connect a radio frequency transmitter/receiver antenna to the antenna's tuning capacitors, but the present invention is applicable to any downhole application requiring the transmission of high electrical current across a barrier having a high pressure differential. This invention minimizes the force acting on the connector due to the high pressure differential by providing a conductor preferably having either a wave-like cross-section or a multi-finned cross-section, thereby minimizing the overall cross-sectional area of the connector yet providing sufficient cross-sectional area of the conductor to carry the necessary amount of electrical current.

Abstract translation: 本发明涉及用于在具有相对较高压力的工具室和具有相对较低压力的另一工具室之间传递电流（优选高频AC电流）的井下高电流低阻抗馈通连接器。 本发明的主要目的在于将射频发射机/接收机天线连接到天线的调谐电容器，但是本发明可应用于需要高电流传输通过具有高压差的屏障的任何井下应用。 本发明通过提供优选地具有波状横截面或多翅片横截面的导体来最小化由于高压差而作用在连接器上的力，从而最小化连接器的整个横截面面积 提供足够的导体横截面面积来承载必要的电流量。

Abstract: A downhole drilling efficiency sensor (DES) apparatus for use in oil and gas exploration, measures important drilling parameters near the drill bit for increasing effectiveness and productivity of the drilling operations. Parameters measured include weight-on-bit (WOB), torque-on-bit (TOB), bending-on-bit (BOB), annulus pressure, internal bore pressure, triaxial vibration (DDS for drilling dynamics sensor), annulus temperature, load cells (10a, 10c) temperature, and drill collar wall (8) inside diameter temperature of a drill string (12). The direction of the bending-on-bit measurement is also determined with respect to the low side of the hole while rotating (or stationary) by using a triaxial vibration sensor and magnetometer array (72). The device combines pressure sensors (74), temperature readings and other sensors capable of collectin all the indicated parameters, for presenting them to the drilling operator such that an accurate views of the downhole drilling parameters, as thermally isolated (66) from thermal effects of borehole fluid (66) are obtained via side wall readout (64).

Abstract: A downhole drilling efficiency sensor (DES) apparatus for use with drilling operations in oil and gas exploration, that accurately measures important drilling parameters at or near the drill bit in order to increase the effectiveness and productivity of the drilling operation. The parameters measured include weight-on-bit (WOB), torque-on-bit (TOB), bending-on-bit (BOB), annulus pressure, internal bore pressure, triaxial vibration (DDS-drilling dynamics sensor), annulus temperature, load cell temperature, and drill collar inside diameter temperature or thermal gradient across such drill collar. The direction of the bending-on-bit measurement is also determined with respect to the low side of the hole while rotating (or stationary) by using a triaxial vibration sensor and magnetometer array. Each of the parameters are known to be important factors in determining the direction, rotation, and rate of drilling. The device described combines sensors capable of collecting all of the indicated parameters and presenting them to the drilling operator such that an accurate view of the downhole drilling parameters can be obtained.
