Abstract

The invention relates to the technical field of oil well online detection, and discloses a horizontal well temperature and pressure online detection device which comprises a capsule shell, a protection cavity is formed in the capsule shell, a communication cable is arranged on the upper side of the capsule shell, an opening is formed in the lower side of the protection cavity of the capsule shell, and a protection shell is arranged at the opening of the capsule shell. By arranging the capsule shell, the test line cavity, the detection line and the like, the device is placed in an oil well and moved to a horizontal well, the moving device drives the detection line to extend and be laid in the horizontal well, the detection line is placed in the capsule shell, and the detection line is placed in the capsule shell. The temperature sensor and the pressure sensor distributed on the detection line are used for carrying out large-range online detection on the temperature and the pressure in the horizontal well, and compared with a traditional single-point test, the device is large in sampling data volume, reliable in test result and capable of accurately reflecting the real situation in the well.

Description

technical field [0001] The invention relates to the technical field of on-line detection of oil wells, in particular to an on-line temperature and pressure detection device for horizontal wells. Background technique [0002] A horizontal well is a special well whose maximum inclination reaches or approaches 90° and maintains a certain length of horizontal well section in the target layer. Sometimes, for some special needs, the inclination can exceed 90°. Generally speaking, water Flat wells are suitable for thin oil and gas layers or fractured oil and gas reservoirs, with the purpose of increasing the exposed area of ​​oil and gas layers. The purpose of measuring the temperature and pressure of horizontal wells is to provide a theoretical basis for the next step of accurately finding water. [0003] Notification number CN104929592 B discloses a horizontal well to find plugging water and oil reservoir pressure monitoring device, including computer and industrial computer loc...
