The oil-water relationship has been varied greatly in XXX oilfield since it was put into development 30 years ago. And in recent years, boron-injected neutron lifetime logging and cased hole resistivity logging are adopted for remaining oil evaluation. This paper establishes logging interpretation standard and provides interpretation methods for both technologies. And they both present better application results by strengthening further understanding on remaining oil in mature oilfield and provide firm basis for the secondary development of the oilfield.

To present situation of the big test risk, long testing period, high cost for high temperature and pressure, big angle and horizontal wells and other difficult and complicated testing wells, by optimizing the operation process of integrated acid test completion string, the above technical problems are solved effectively. The process is widely used in operations of acid fracturing completion, the straddle water shut-off across, separated layers production which has an important sense for speeding up oil exploration, development pace and growth of oil reserves and production.

Constrained by backward of test technology in horizontal well, lack of developing dynamic analysis information, incompletion of dynamic analysis means, it results in no basis for selecting measures of increasing production and its implementation, affecting development result. Coiled tubing test equipment system in horizontal wells consists of surface power system, wellhead sealing BOP system, down hole testing instrument system, surface data acquisition system. The system has technical innovations in the long-real-time monitoring and test instruments protection in horizontal wells. Its development and successful applications solves the technical problems of the dynamic monitoring in horizontal wells and lays the foundation for improving the development effect.

Taking the pressure drop curves in injection well as study examples, a comprehensive analysis for more than 200 of drop curve characteristic is made. By morphological classification assessment, combined with examples of dynamic verification, and tracking and analysis of changes of a well water pand phase pressure drop curves, understanding to every types of injection wells reservoirs are deepened, which has some guidance and reference for adjustments and evaluation of injecti on wells net.
