Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] see figure 1 , a portable on-site density sensor calibrator, including a box body and a calibrator plate fixture b arranged in the box body a and a calibrator body c; two parts are composed of an instrument box, and the calibration plate is on the left Fixture, the right side is the body part of the calibrator.

[0020] see figure 2 , the check plate fixture is mainly composed of the check plate bracket upper beam 11, the check plate support lower beam 8, the check plate support pole 7, the check plate 6, the screw 3, the handle 1 and the steel pipe clamp 4, The specific connection is as follows: the upper beam 11 of the check plate support, the lower beam 8 of the check plate support are horizontally spaced up and down and are supported by the check plate support poles 7 on both sides to form a support. The two ends of the check plate support pole 7 are resp...

Abstract

A portable in-situ density sensor calibration instrument comprises a box body, a calibration disc clamp and a calibration instrument body, wherein the calibration disc clamp and the calibration instrument body are arranged in the box body. The calibration disc clamp mainly consists of an upper beam, a lower beam, vertical rods, a calibration disc, a lead screw, a handle and a clamping part. The specific connecting mode is as follows: the upper beam and the lower beams are vertically arranged in a horizontal spaced mode and are supported through vertical rods on two sides to form a support; the upper beam penetrates through the lead screw in a threaded matching mode, and the upper end of the lead screw is connected with the handle, and the lower end of the lead screw is connected with the clamp. The calibration disc is fixed to the lower beam, and a seal ring and a calibration air interface connected with an air supply pipeline of the calibration instrument body are respectively arranged on a disc body. The portable in-situ density sensor calibration instrument is better in pressure stabilization effect, can completely meet the density sensor calibration requirement in a site. On the aspect of application, an air source and a power source are not needed during system calibration, calibration air is automatically supplied, calibration and usage under the conditions of the site are facilitated, a system is automatically matched to form a whole, and equipment, storage and carrying are facilitated.

Description

technical field [0001] The invention belongs to the technical field of mud logging engineering, in particular to a portable on-site density sensor calibrator which is convenient for field mud logging in oil and gas fields. Background technique [0002] The density sensor is used to measure the density of the drilling fluid, which is an important mud logging parameter in the mud logging industry. However, because the equipment for calibrating the density sensor is relatively complicated, it is not convenient to take it to the field for use, so the device and method for calibrating the density sensor on the spot have been vacant, which has brought inconvenience and problems in the use of the density sensor. Contents of the invention [0003] The invention aims at the defects and deficiencies existing in the application of the prior art, and provides a portable density sensor calibrator with reasonable design, convenient operation, high calibration accuracy and convenient fie...
