The paper presents the reason and result for the reforming of the craft to prepare for fracturing base fluid,and outlooks its development in the future.

This paper analyzes the result on spot experiments confecting fracturing base fluid influence on 6 factors,explains the influence mechanism for 6 factors,ensures the best condition on confecting fracturing base fluid through the face-crossing experiment.

This paper studies the field test on the practicability of the rebirth of the rest fracturing base fluid in fracture construction,analyzes the result,and discovers the calculating method after mixing fracturing base fluid in different paste values.

Experiments were done to optimize the oil base fracturing fluids, in which the dewatered crude from Huangchang oilfield was used as the base fluid, LHPG02 (a phosphate) was used as the gelling agent, sodium metaaluminate as the cross-linking agent, and anhydrous sodium acetate as the gel breaker.

The synthesis condition of gelling agent phosphate ester in oil base fracturing fluid is studied on this paper.

Quality control technology of water-base fracturing fluid for field operation.;

Especially, the water-base fracturing fluid has adapted encapsulated gel-breaking technique,.

The preparation of low damaging, high temperature resistant and delayed organic borate-zirconate crosslinker CZB-03 for aqueous hydrofracturing fluids (AHFFs) is presented.
