Research On Matching Technology Of Complex Reservoir Well Test In Bayanhetao Basin

In 2018,major breakthroughs were made in the exploration of the Gilantai structural Belt in the Bayanhetao Basin,breaking the situation that the area has been unable to be exploited for 40 years.The exploration and testing of loose sandstone and gneiss reservoirs in this area are not yet complete.In order to further enhance the pertinence,reliability and practicability of the test data,and effectively guide exploration and development,it is urgent to carry out the research work which is supporting the test,ensure increased reserves and stable production,improved quality and efficiency,provide technical support for the integrated strategy of oilfield exploration and development.This article is based on the technical problems faced by the complex reservoir testing technology in the Bayanhetao Basin,through integrated testing technology,testing work system optimization,real-time monitoring of test data,PVT sampling,reservoir dynamic evaluation and interpretation,etc.,technical research has been carried out to form a supporting testing technology suitable for Bayanhetao Basin.In this paper,by optimizing the testing work system,the requirements of testing work system are established.In view of the low success rate of PVT sampling in Jilantai oilfield in Bayanhetao,the principle of PVT sampling standard was established.Design and improve electromagnetic wave wireless transmission tools and string structure,improve the performance of signal transmission.The application of this supporting technology in the Bayan Loop area has achieved remarkable results in terms of success rate and technological innovation.
