Oil well suppressing pressure experiment recorder using GPS positioning technique

Abstract

Disclosed is an oil well holding-pressure experiment recording instrument adopting the GPS positioning technique, which pertains to the technical field of instruments used by oil wells. The recording instrument is composed of an intellectual host computer, a GPS receiver module, a data acquisition module and a pressure sensor; the intellectual host computer first positions the coordinate of each oil well to be tested by controlling the GPS receiver module and conserves the result of the positioning and the corresponding information of well names in the data base of the intellectual host computer; the password is adopted to control the authority of accessing the well position data base on the intellectual host computer; only the users with the authority of administer can carry out modifying and writing operation to the data base. The recording instrument has the advantages that the oil well holding-pressure experiment recording instrument solves the problem that the data recorded by oil well holding-pressure experiment recording instrument automatically corresponds to the well names, eradicates the generation of false data and increases the reliability of the acquisition curve.

Description

technical field [0001] The invention belongs to the technical field of instruments for oil wells, and in particular provides an oil well pressure test recorder using GPS positioning technology. Background technique [0002] Periodic pressure holding tests for production oil wells have always been one of the important means for the maintenance of oil production equipment (pumping units, screw pumps, etc.) in major oil fields in China and early detection of potential failures. one. In the traditional oil well pressure test, the manual method is mainly used, and the pressure gauge and stopwatch are used to record the pressure and corresponding time data. This method has a limited number of recording points, and the recording accuracy of the data is affected by the operator's operating level and sense of responsibility. Due to the limitations of human factors, data quality is difficult to guarantee, and curves cannot be drawn in time, the accuracy and timeliness of diagnosis ar...
