Embodiment Construction

[0053] see figure 1 , which shows a side view of the adjustable downhole sand control screen 5 . The sand control screen 5 is composed of three parts, namely the upper screen 6 , the lower screen 7 and the valve screen 8 . Each of these screens can be constructed in a manner known to those skilled in the art. For example, if Figure 3B As shown, the screen can include a central pipe 10 , longitudinal fins 11 and a screen 12 . In this particular invention, the base tube 10 has no perforations to allow fluid to flow between the outside and the inside of the base tube. In this respect, the base pipe 10 described differs from production screens known in the art. The longitudinal ribs 11 are arranged around the outside of the central pipe 10 in the longitudinal direction. The screens 12 are then wrapped around the longitudinal fins 11 to define channels 13 between the central pipe 10 , adjacent longitudinal fins 11 and the screens 12 . Said channel 13 is the part between the ...

Abstract

An adjustable downhole screen assembly (5), which includes: a pipe string (10) connected to a production oil pipe, the pipe string including holes extending from the inner diameter of the pipe string to the outer diameter of the pipe string; connected to the pipe string and a screen adjacent to the string aperture; a valve (31) connected to the string, said valve controlling the flow of fluid through the string aperture; a valve motor mechanically connected to the valve (32), the valve motor opens and closes the valve, and a valve controller communicatively connected to the valve motor, the valve controller instructs the valve motor according to the status of the valve.

Description

[0001] related application [0002] This application is related to commonly assigned application WO / 03 / 023185A1. technical field [0003] The present invention relates to an adjustable downhole screen assembly for controlling the flow of fluid from a hydrocarbon containing formation into the production tubing of a hydrocarbon fluid production well. [0004] The invention also relates to a hydrocarbon fluid production well equipped with one or more downhole screen assemblies. Background technique [0005] Well completion techniques to expel solid particles produced by wellbore fluids are well known in the gravel packing art. [0006] The practice of constructing a wellbore that penetrates the formation often requires the placement of steel casings or other conduits within the wellbore. In some wellbore configurations, the casing is cemented within the wellbore by Portland cement in the annulus between the casing and the wellbore. The casing may be deployed at a depth throu...
