Development of geophysical complex hydrodynamic research collectors

Abstract

Describes the results of work on creation of geophysical informational and communicative complex which is capable to provide not only continuous monitoring of hydrodynamic processes which are occur in the bottom-hole formation zone in primary drilling, testing and operation of wells, but also the management of these processes in real time. The main objective of the research is the preservation of primary filtration capacity properties of the reservoir. Provides the general requirements to a method and equipment for determination of the hydrodynamic parameters of layers in the well. On the basis of theoretical research a method of hydrodynamical logging (GDK) with modified probe side of micrologging (GDK-MBMK) is developed, in which the electrical characteristics of the reservoir are recorded simultaneously with the selection of the sample. Designed and tested experimental sample of multi-channel down-hole geophysical equipment with autonomous power supply intended for remote control of hydrodynamic characteristics and mode of operation of the productive inter-roll for separately dual use (DCP), and separately-separate for-rolling (ARD).Continuously recording in the bottom space of packer this apparatus provides information about the bottom-hole pressure, the production rate, moisture content and temperature. During the communication session, results of measurement pass by the wireless communication channel in real time. Noise-type signals based on algorithms, which are capable of providing the recorder with highly accurate information, is used. The cross-validation testing of the autonomous down-hole information measurement module and of the autonomous pressure gauge, which is built-in the single apparatus, has been made. High reliability performance, accuracy in measurement, high noise immunity towards the electromagnetic fields of the electrical equipment of neighboring wells have been shown by this apparatus. This complex has been recommended for using in field researches of wells which are equipped with technologies of multi-level oil and gas recovery.
