Oilfield Deep Heavy Mixing Light Viscosity Reduction Technology Research And Applications

The crude oil has the good fluidity under the oil deposit condition, but after enters the well chamber in the vertical mobile process along with well chamber temperature reducing, the crude oil viscosity increases, the mobile change in sexuality is bad, causes the oil well to be unable to go into production and to maintain the production. Moreover, as a result of the karst seam hole oil deposit reservoir particularity and the complexity, the oil layer produces can change in a big way, maintains with difficulty in the oil deposit pressure under the condition, the oil well will be able to change over to the artificial lift early, this will be able to bring the major difficulty to the deep well thick oil lifting. The Tahe oil field ultra in-depth thick oil oil field is the new development oil field, because crude oil nature anisotropism and flowing life short, on produces the scale in a big way, time short, the extraction craft technology not yet forms a complete set, thick oil mining and the development and on produce the difficulty is very big. Seeks suits the Tahe oil field ultra in-depth thick oil the well chamber to fall sticks with the lifting necessary craft technology, is the ultra in-depth thick oil oil-field development urgent matter.This article through analyzes the Tahe oil field in-depth thick oil oil deposit the characteristic, unifies the domestic and foreign earlier periods the technological development condition below, mainly develops studies: The Tahe oil field in-depth thick oil mixes thinly falls sticks in the room the experimental study, through the thick oil race component analysis, mixes thinly falls sticks in the room the experiment and mixes thinly falls sticks the effect optimization research, falls for the thick oil well chamber sticks provides the theory strut, for next step falls sticks the plan the formulation to lay the foundation; The Tahe oil field in-depth thick oil mixes thinly falls sticks the value simulator study, through the well chamber temperature field, the pressure field and the fluid state field analog computation, unifies the value analogue result which the well chamber mixes thinly falls sticks, determined the Tahe oil field well chamber mixes thinly falls sticks the plan. The Tahe oil field well chamber mixes thinly falls sticks the engineering research; The Tahe oil field in-depth thick oil mixes thinly falls sticks the field application, to mixes through the field application thinly falls sticks the technology to carry on the system the appraisal, consummates the Tahe oil field to mix thinly falls sticks the technology, forms has Tahe oil field own characteristic to fall sticks the craft series.
