Visual logging system for oil field collection

Abstract

The invention discloses a visual logging system for oil field collection. The visual logging system comprises a ground control device and an exploring tube device. The ground control device comprisesa ground host and a computer, a high-brightness LED light source and a high-definition wide-angle camera are installed at one end of the exploring tube device, a view screen processing unit, a loggingcable network image transmission unit, an underground power supply and an attitude detection device are arranged in the exploring tube device, the attitude detection device comprises three electromagnetic wave transmitting devices, and the ground host is provided with a view screen decoding unit, a video storage unit, a communication control unit, an underground power supply unit, a cable image transmission unit and a computer interaction unit. The detection cost is reduced, the detection efficiency is improved, the applicability is high, and people can obtain the accurate depth of a view screen source; and meanwhile, the shooting posture of a hard tube at the tail end of the exploring tube device can be obtained, so that the specific direction of a seepage opening is obtained from an image, and data obtained through well logging is more three-dimensional and more accurate.

Description

Technical field[0001]The invention relates to the technical field of oilfield re-production, in particular to a visual logging system for oilfield acquisition.Background technique[0002]At present, my country’s crude oil supply is facing various uncertainties, including: First of all, my country’s oil self-sufficiency rate is low, a large amount of crude oil relies on imports, the trade war with the United States and the turbulent situation in the Middle East have greatly affected my country’s oil trade. Stability poses a serious threat to our national security. In addition, the low probability of discovering large and super large new oil fields in a short period of time means that new wells with high oil production cannot be dug. At the same time, there are a large number of abandoned, low-yield old oil wells in current oil production operations, causing great Based on the above considerations, a more feasible solution is to increase the oil output of old oil wells through measures ...

AI Technical Summary

Problems solved by technology

[0003] Before resuming production of old oil wells, when performing visual logging, the existing logging equipment uses straight pipe detection pipes for detection. Therefore, it is necessary to excavate before detection. It cannot be used directly, and when the existing logging device monitors the leakage point, the depth of the leakage point can only be determined by the length of the extension, and the leakage point can only be judged in the vertical direction. not accurate
