摘要： A sintered metal screen (S1) is releasably suspended from a packer mandrel (26) by a locking mandrel (50) and a landing nipple (24). The sintered metal screen (S1) and locking mandrel (50) are retrievable with the assistance of a running tool which is insertable into the bore of the locking mandrel. According to this arrangement, the sintered metal sand screen may be removed and replaced without retrieving the packer (28) or the production tubing (34). In one embodiment, the sintered metal screen is enclosed within the bore of a sliding side valve (62). The sliding side valve (62) may be opened and closed as desired for selectively admitting production from various producing zones, or for isolation of a damaged screen. In another embodiment, an auxiliary sintered metal screen (82) is inserted into the bore of a primary screen, for example, a conventional wire-wrap sand screen (94).

摘要： An improved system and method for performing inversion and for correcting for shoulder bed effect. The method enhances the resolution of wave propagation resistivity logs and corrects the logs for adjacent bed effects, whereby the resulting logs have a vertical response as good as wireline high-resolution induction logs. The method first performs logging while drilling on a formation to obtain LWD resistivity log data. The method then selects one or more control depths at one or more locations of each of a plurality of detected beds in the formation. The present invention includes a novel method for selecting bed boundaries from the log data, and the control depths are then determined based on the determined bed boundaries. The method then estimates the resistivity of each bed only at the selected control depths to produce an estimated resistivity of the beds. The method then computes a simulated log value at each control depth using a current estimate of the resistivity of the beds. The computed simulated log is then compared to the actual log data at each control depth, and the resistivity of each bed is adjusted using the difference between the actual and simulated values at the control depths. The above method iteratively repeats a plurality of times until the simulated log substantially matches the actual log at the control depths. The method for determining the bed boundaries in the formation preferably comprises fitting a cubic polynomial in depth to the conductivity, or log of the conductivity, using a weighted linear least-squares method. The curve fit of the log data is performed a plurality of times on portions of the log data using a windowing method. This windowing method comprises moving a window across the log data at periodic increments, and performing the curve fit on the window of log data at the periodic increments as the window is moved across the log data. The method then determines inflection points of the log data after the curve fit for each of the windows. The method then selects bed boundaries from the inflection points of the curve-fit of the log data.

摘要： A hydraulic release mechanism for retrieving a stuck downhole tool (250) from a well casing (202) having an elongated, cylindrical jack body (216), a piston (208) carried in a bore in the jack body and a latching portion (212) carried co-axially by the jack body for connecting with the stuck tool (250). The piston is movable within the jack body under the influence of fluid pressure from a first position to a second position. The movement of the piston to a position intermediate its first and second positions causes an anchor slip member (234) to ramp over a wedge member (236) and expand radially outward against the well casing to restrain further longitudinal movement of the piston in the casing. A shearable element (244) prevents relative motion between the anchor slip member and the jack body until the anchor slip member is moved radially outward against the well casing. The shearable element shears and releases the jack body for longitudinal motion in the casing relative to the piston when the anchor slip member is expanded radially outward against the casing, locking the piston in place. The latching portion (212) is operatively engageable with the tool in a manner permitting the stuck tool (250) to be lifted loose when the jack body is moved longitudinally relative to the locked piston under the influence of hydraulic pressure until the locked piston assumes its second position in the jack body.

摘要： A gas flow control device (60) for injecting gas into a downhole production string for recovering pressure and reducing frictional losses, so that critical flow can be reached at lower pressure drops and higher production pressure, includes a housing, inlet ports (54), nose end (61) with check valve (65), and outlet ports (64), and a nozzle (34) having first and second ends, and a flow path therebetween, and a Venturi having first and second ends, and a flow path therebetween. The first end of the Venturi portion is disposed adajcent to the second end of the nozzle. The Venturi flow path is coaxially aligned with the nozzle flow path to provide a continuous flow path therethrough. Such a flow control device that has a gas flow rate performance that is independent of the tubing pressure, even when the tubing pressure is as high as 80 % to 93 % of the casing pressure, can be used to increase the production rate, improve the lift efficiency, and eliminate or suppress instability in continuous-flow gas lift wells.
