Technology To Improve Injection Wells Testing And Debugging Efficiency Research And Application

The research of injection wells measuring and debugging technology refers to that asinjection wells' number increases year by year, injection-production relationship becomesincreasingly sensitive and adjustment of injection scheme becomes more and morefrequently, so research is projected for carrying out injection scheme timely and effectively,the purpose of which is to improve the test efficiency of injection wells, shorten the holdingtime during single well's test, implement injection scheme timely and effectively andguarantee the stable and ascending production of water flooding oilfields.This paper analyzes and studies main factors that effect test efficiency of injectionwells, determine the main purpose of the research project on the basis of comprehensiveanalyzing some aspects like the current management mechanism of the measuring anddebugging work, rationality of working system like testing circle, the aging degree of waterflooding pipeline network, reasons resulting in deficiency of testing power and ways tocontrol water amount on pipeline network, etc.Studying methods to reasonably optimize injection wells' test cycle, proposing thescheme of key guarantee for key well; studying the technology of testing as well asdebugging, mainly introducing advanced technology to improve the test efficiency ofinjection wells; studying water-dividing figure and using it to replace the precious operatinginstructions of injection wells to make post operators control injection wells' productionparameters basing on mastering the underground water-dividing state; studying thesafeguard mechanism of injection wells' testing and debugging, providing basic guaranteefor this work.This paper proposes the research thought basing on the present situation of Jilinoilfield water injection system, formulates solutions combining existing problems,fundamentally solve some bottleneck problems that restrict the further development ofinjection wells test technology, so it will have broad application value.
