The Storable Multi-parameter Measuring Well Apparatus

It is an phenomenon in our country at present that many oil wells come intothe output wane and reduce the producing oil rate. To the state, the researchersuggest a means which using the dynamic inspecting technique seeks the residualoil, thereby, improving the producing oil rate. The paper provides a means whichanalyzing and researching the oil well by using the stored testing and measuringtechnique, to judge the quality of the oil storage layer and ascertain thehydro-parameter, providing the reliable information for exploring oil field.Based on the application environment and the stored tested technicalrequirement of the well-down oil, the paper introduces in detail the structureof the testing system and the hardware and software design of the system usingC8051F310 MCU according to the design principle and theory of the stored testingand measuring system. Simultaneously, the exterior FLASH Memory is used to storethe data of the system , it solves the demand of the storage data. Thecommunicational component communicate with PC by RS232 serial device, itdisplays the work-state of the testing system.The stored multi-parameter measuring system in the paper is five parameterstorage system, either analog signals or pulse signals is the five signals. Thetesting system is comprised of the adjusting signal, collecting information,storing information and the interface of input and output , it processescollecting dynamic real time data, storing, postmortem callback, reappearingdata and analyzing data to the work environmental parameter of the tested object.It can work normally under the tested environment, it has not an impact to thework of the tested object. During working, the working of the whole testing systemis controlled by software.Via the dynamic stored testing to the well-down oil, the paper provide theimportant information research datum for improving the producing oil rate. Thesystem apply mainly to the medium-term and upper product testing well and projecttesting well of exploring oil, it measures the information of the radioactiveintensity of the stratum, temperature, stress, the flux of the tube, and so on.It provides a reliable testing method for secondly or third oil extraction.
