Change Mechanism Of Delay Cementation Quality Of Adjustment Well In Daqing Oil Field

With the extension of acoustic variable density logging time, the detection result of acoustic variable density logging impacted with various factors dropped dramatically. This variety made drilling, cementing in many new difficulties and problems. And put forward a new research project in cementing technology of adjustment well. The effect factors are complex, involving cementing material, formation, technology etc, in order to radically out delay conditions cementing quality of variation and the influencing factors, and the changes in the way, not only to the experimental study on the laboratory, in order to improve the performance of the cementing quality of adjustment Well.Depending on the simulating device, the evaluation method of the laboratory, microcosmic structure analysis and numerical simulation method, the delay cementation quality variation mechanism of adjustment Well in Daqing oil field is analyzed and expounded.
