Abstract

An measuring system for measuring ultra-thick oil underground temperature and pressure two-parameter (multi-point) dynamic, applied in the art of temperature and pressure measuring technology, consists of a flat valve, a well shutting device, an upper flange, a continuous oil-pipe seal, a cross joint, a connector, an armoured thermocouple, a capillary, a continuous oil pipe and a continuous oil-pipe suspending device. The present invention is characterized in that the upper part of the cross joint is provided with the upper flange and the left part of the cross joint is provided with the flat valve; the upper part of the upper flange is provided with the well shutting device; the right shoulder of the upper part of the upper flange is provided with the continuous oil-pipe suspending device and the continuous oil-pipe seal; the left part of the well shutting device is provided with the flat valve; the continuous oil-pipe suspending device is provided with the continuous oil pipe and the connector; the connector is provided with the armoured thermocouple and the capillary. The system with novel and scientific design can achieve the collecting, displaying, storing and transferring of system pressure and temperature.

Description

Technical field: [0001] The invention relates to the technical field of temperature and pressure measurement, and is mainly used for a super-heavy oil downhole temperature and pressure dual-parameter (multi-point) dynamic measurement system for steam-assisted gravity drainage (SAGD) technology in the exploitation of heavy oil and super-heavy oil . Background technique: [0002] At present, in the field of temperature and pressure measurement technology at home and abroad, the temperature and pressure parameters of oil wells downhole are key to the production of heavy oil and super heavy oil and the application of steam-assisted gravity drainage (SAGD) technology. Dynamic measurement of temperature and pressure of vertical wells and horizontal wells of meters (or deeper). However, due to the harsh working environment of the sensor, it is difficult to guarantee the strength and measurement accuracy. Generally, steam injection wells and oil production wells in oil fields are ...
