The complexity and depth of drilling are increasing constantly, so an advanced well control technology is required, and early kick detection as the key to well control is very important. Rapid and accurate kick detection helps to eliminate kick and rebalance the wellbore pressure, which not only improves drilling operation efficiency, but also reduces the probability of blowout, well collapse and other accidents. Accordingly, this paper has analyzed the applicable conditions, advantages and shortcomings, and field applications of the existing kick detection technology including mud pit surface detection, delta flow method, liquid level monitoring in the wellbore detection, gas invasion detection, kick detection while drilling, multi-parameter comprehensive detection system and comprehensive logging detection and analysis technology, and proposed the research trends and application suggestions of kick detection technology.
Highly deviated wells are widely used in the development of marine oilfield, old oilfield and low permeability oilfield. However, during the drilling process, cuttings bed is often formed in the highly deviated section, which affects rate of penetration and downhole safety, and restricts the development of drilling technology of the highly deviated wells. Therefore, the critical velocity to protect stationary bed development(CVPSB)was studied to overcome the shortcoming of the critical velocity to protect bed development(CVPB). This paper advanced a new method to identify CVPSB, developed two-layer model and three-layer model, and analyzed the effect of different parameters including hole angle, cutting diameter, ROP etc on the CVPSB. This paper may serve as a guideline for controlling parameters in drilling and choosing model in developing cuttings bed software.All rights reserved.
