Application and Practice of Debugging While Testing Technology in the Exploitation of a Low-Permeability Oil Field

Abstract

The reservoir types of a low permeability oilfield are complex and diverse, the injection volume of water injection wells is less, the number of layers is more, and the interlayer contradiction is more prominent. It is difficult to use the routine debugging for this king of water injection well, the workload is large and time-consuming. In view of this situation, the Debugging while testing technology is introduced. The application of this technology solves the difficulty of conventional Testing, and alleviates the contradiction between debugging demand and debugging ability, and makes each layer balanced, effective, timely and accurate water injection according to reservoir needs, which well mets the needs of reservoir. By comparing and analyzing the technical advantages and application effects of debugging while testing technology and conventional testing technology under different conditions, this paper summarizes the direction for use of debugging while testing technology, and provides a guiding basis for futher popularizing debugging while testing technology. Improve the qualification rate of stratified water injection.
