Engineering and technical support of cementing during well construction at the Astrakhan GCF

IMG_9572.JPG     IMG_9568.JPG

At present, the laboratory of cementing slurries of"Octopus" JSCfulfills contractual obligations on the following subjects:"Provision of services for the analysis of cement and selection of cementing slurry recipes for geological and technical conditions of the Astrakhan GCF wells"; "Engineering and technical support of cementing during well construction at the Astrakhan GCF ".

The laboratory of cementing slurries selects the recipes of cementing slurries for the conditions of the Astrakhan GCF during construction, capital workovers and abandonment of the wells.

The laboratory tests of slurries, as well as of cement stone, are carried out in accordance with the requirements of GOST 1581-96 Technical Specifications; GOST 26798.1 - 96. Packing Cement. Test methods; Standards API; Passports and operation instructions of devices.

When selecting recipes, the requirements of industry standard of Gazprom RD 2.1- 148 - 2005 are taken into account.

The analyses are carried out using modern Russian-made equipment in the following volume:

-         Determination of the cement slurry density.

-         Determination of the cement slurry spreading.

-         Determination of the thickening period of cement slurry in the conditions corresponding to those of wells.

-         Determination of the timing of cement slurry setting.

-         Determination of the strength of cement stone for compression and bending in accordance with GOST 26798.3 -96; GOST 310.4.

-         Measurementofwatertrapping. 

The implementation of this set of studies makes it possible to balance the acceptable terms of thickening and the strength of cement stone in accordance with the requirements of GOST.

The control analyses are also carried out after preparation of the grouting fluid. This helps to prevent emergencies during the cementing of wells and installation of cement bridges.

Thus, for the previous and current years in "Gazprompodzemremont"LLC, there has not happened a single incident coming from the cementing slurry premature setting.

The laboratory activity is determined by the following documents: GOST 12.1.007 - 76. System of Operational safety standards. Harmful substances. Classification and general safety requirements as well as internal documents: "Instruction on labor protection for the analytical laboratory personnel" and "Instruction on fire safety".
