Sand control screen pipe capable of measuring compaction settlement stress in hydrate pilot production process

Abstract

The invention discloses a sand control screen pipe capable of measuring the compaction settlement stress in the hydrate pilot production process. The sand control screen pipe comprises a casing pipe, an upper well completion pipe column and a lower well completion pipe column, the upper well completion pipe column and the lower well completion pipe column are installed in the casing pipe, the upper well completion pipe column is located at the upper end of the lower well completion pipe column, and the upper well completion pipe column comprises a single-action directional plug-in communication assembly and an oil pipe. The lower well completion pipe column comprises a connecting assembly, a sand control screen pipe and a measuring unit, the single-action directional plug-in communication assembly is directionally inserted and clamped to the corresponding position of the connecting assembly, a single-action device and a communication device are arranged on the single-action directional plug-in communication assembly, the single-action device fixedly sleeves the oil pipe in a limiting mode in the axial direction, and the single-action device is used for maintaining the oil pipe not to rotate along with the single-action directional plug-in communication assembly when the single-action directional plug-in communication assembly rotates. Signal communication between upper well completion and lower well completion is achieved, and the compaction and sedimentation effect in the hydrate depressurization pilot production process can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of hydrate test production measuring devices, in particular to a sand control screen capable of measuring compaction and settlement stress during hydrate test production. Background technique [0002] The depressurization test production method is considered to be the mainstream technology for hydrate test production, but during the depressurization test production process, reservoir compaction and settlement may occur in the production well. For example, in a certain year in the Nankai Trough in Japan, the seabed deformation was measured and it was confirmed that the top of the production well had subsidence on the order of centimeters after several days of decompression and test production. Sand phenomenon. [0003] Compared with the gas production application of conventional oil and gas wells, the service life of the sand control screen used in the hydrate test production in the ocean is far from the ori...
