    Abstract
  • A comprehensive method for evaluating the anti-channeling performance of cement slurries under dynamic complex pressures was developed for the purpose of improving the job quality of cementing adjustment wells under dynamic complex pressures and satisfying the requirements of performing well cementing without interrupting water injection job nearby in the Bohai oilfield. This evaluation method involves three devices, which are a self-developed device for evaluating the performance of resisting dynamic water dispersion, a device for evaluating the anti-channeling performance of interfaces between cement sheath and casing string/borehole wall, and a device for measuring the volume of plastic materials. This method can be used to evaluate the performance of a cement slurry aimed at dealing with difficulties such as disordered and complicated pressure system, low quality of pay zone cementing job and poor isolation between different pay zones. A new anti-channeling cement slurry was developed based on the evaluation and optimization of anti-dynamic water dispersion agents, expanding agents, toughness enhancers and cement retarders etc. The development of this new cement slurry was aimed at dealing with problems encountered in cementing wells affected by the dynamic pressure system in the Bohai oilfield. Compared with the cement slurries used in this oilfield, the set cement of the new cement slurry had compressive strength that was increased by 18.6%, bonding strength increased by 28.7%, pressure to resist water channeling increased by 60.8%. This new cement slurry has also been used in four wells in the Penglai oilfield, and the well cementing job quality was enhanced by 22.3%-37.5% over the job quality of cementing performed previously. Field application of the new anti-channeling cement slurry has indicated that it has excellent anti-channeling capacity, and is able to greatly improve the well cementing job quality of adjustment wells drilled in formations with complex pressure system. This new cement slurry helps realize well cementing without interrupting water injection operation, and has broad prospects of application in the future.
