摘要： In order to ensure that at least some of the tools (12-1) to 12-4) in a string of tools that is permanently installed in an oil well (10) are kept in operation even in the event of a localized fault, the link (18) interconnecting the tools and a surface installation (16) is subdivided into segments by switch members (20). More precisely, a switch member is associated with each tool. In addition, the link (18) forms a loop with both ends thereof being connected to the surface installation (16).

摘要： The present invention provides an improved apparatus for mounting an electronic device such as a sonde therein for use in directional drilling. Such an apparatus includes an elongated housing having projections at opposite ends of the housing for connecting the housing to other components of the boring machine, an elongated internal chamber configured to receive an electronic device therein and having an elongated access opening which extends along an exterior surface of the housing, and a cover sized to close the access opening, the cover having a first hole extending therethrough. The housing includes a second hole which comes into alignment with the first hole when the cover is in a position to close the access opening, and has a third hole at least partially intersecting the second hole, whereby when a pin having a head for holding down the cover is inserted in the first and second holes, a retainer such as a roll pin for engaging the pin may be inserted in the third hole in a manner effective to engage the pin so that the pin holds down the cover. According to preferred form of the invention, the pin preferably has an enlarged diameter head which seats against a step in the first hole to hold down the cover, and a concave groove that comes into alignment with a round interior surface of the third hole when the pin is fully inserted so that the head engages the step. The retainer can then extend into the concave groove in the pin to prevent removal of the pin from the first and second holes. A side load sonde housing according to the invention has improved strength yet remains easy to open and close.

摘要： This invention provides a method for controlling production operations using fiber optic devices. An optical fiber carrying fiber-optic sensors is deployed downhole to provide information about downhole conditions. Parameters related to the chemicals being used for surface treatments are measured in real time and on-line, and these measured parameters are used to control the dosage of chemicals into the surface treatment system. The information is also used to control downhole devices that may be a packer, choke, sliding sleeve, perforating device, flow control valve, completion device, an anchor or any other device. Provision is also made for control of secondary recovery operations online using the downhole sensors to monitor the reservoir conditions. The present invention also provides a method of generating motive power in a wellbore utilizing optical energy. This can be done directly or indirectly, e.g., by first producing electrical energy that is then converted to another form of energy.

摘要： A logging-while-drilling density sensor includes a gamma ray source and at least two NaI detectors spaced apart from the source for determining measurements indicative of the formation density. A magnetometer on the drill collar measures the relative azimuth of the NaI detectors. An acoustic caliper is used for making standoff measurements of the NaI detectors. Measurements made by the detectors are partitioned into spatial bins defined by standoff and azimuth. Within each azimuthal sector, the density measurements are compensated for standoff to provide a single density measurement for the sector. The azimuthal sectors are combined in such a way as to provide a compensated azimuthal geosteering density. The method of the invention may also be used with neutron porosity logging devices.

摘要： A method and apparatus that allows communications of electrical power and signaling from downhole component to another downhole component employs an inductive coupler assembly. In one arrangement, one portion of the inductive coupler assembly is attached to a production tubing section and the other portion of the inductive coupler assembly is attached to a casing or other liner section. The production tubing inductive coupler portion is electrically connected to a cable over which electrical power and signals may be transmitted. Such power and signals are magnetically coupled to the inductive coupler portion in the casing or liner section and communicated to various electrical devices mounted outside the casing or liner section. In other arrangements, inductive coupler assemblies may be used to couple electrical power and signals from the main bore to components in lateral branches of a multilateral well.
