Embodiment 1

[0042] See figure 1 , figure 1 It is a schematic structural diagram of a direct-reading storage integrated noise logging tool provided by an embodiment of the present invention. figure 1 The noise logging tool in includes a circuit assembly 1 , a sensor assembly 2 , an adjustment assembly 3 and a single-core plug assembly 4 connected in sequence.

[0043] Specifically, the sensor assembly 2 is used to collect relevant data in the well, and transmit the collected data to the circuit assembly 1 . The circuit component 1 realizes the storage, processing and output of the collected data. The output end of the circuit component 1 is connected to a high-speed remote transmission, and the high-speed remote transmission sends the data output by the circuit component to the ground numerical control to realize direct reading of the data. The main function of the regulating assembly 3 is to balance the pressure change inside the sensor assembly 2 due to the temperature change. The sin...

Abstract

The invention relates to a direct-reading and storage integrated noise logging instrument, which includes a circuit assembly, a sensor assembly, a adjusting assembly and a single-core plugging assembly which are successively connected; the circuit assembly comprises a first circuit plate, a second circuit plate and an adjustable pin; the first circuit plate and the sensor assembly are connected tostore collected data of the sensor assembly; the second circuit plate is connected with the first circuit plate to treat the collected data output by the first circuit plate; and the adjustable pin is connected with the second circuit plate to transmit data treated by the second circuit plate. The embodiment of the invention adopts a working style of direct-reading and storage integration, the problems of single working style of existing noise logging instrument and only storage or only direct reading are overcome, data storage is achieved, at the same time, log data can further be observed in real time on the ground, and the technical gap of the single working style of noise logging instrument is made up.

Description

technical field [0001] The invention belongs to the technical field of petroleum logging instruments, in particular to a noise logging instrument integrated with direct reading and storage. Background technique [0002] Under the influence of many factors such as formation temperature, pressure difference, acidification erosion, formation stress, and mechanical force during stimulation operations, the casing of oil and gas pipes will be deformed, damaged, and corroded, which will directly affect the high and stable production of oil and gas wells. Therefore, , Casing damage judgment and detection of oil, gas and water leakage points are very important in the oil and gas field development process, which can effectively evaluate the casing damage degree, damage speed and workover effect, thus providing a basis for the design of the workover plan. [0003] Noise is gaining more and more attention and interest due to its increasingly important role in understanding downhole flui...
