摘要
Abstract
The Shenfu Block has deep coal seams with low porosity,low permeability,low pressure,which are prone to adsorption damage,blockage damage,hydration swelling damage,and chemical damage.When using HXS fracturing fluid,there are problems such as significant damage to the reservoir,cumbersome fluid preparation processes,and high friction.Therefore,a low damage variable viscosity and slippery hydraulic fracturing fluid suitable for this block was optimized and designed with medium and low molecular weight lotion polymerized thickener as the main agent,and its comprehensive performance was evaluated.The results indicated that the variable viscosity and slippery hydraulic fracturing fluid had the characteristics of high drag reduction performance,low reservoir damage,easy backflow,and easy preparation.Indoor testing showed a drag reduction rate more than 75%,a surface tension of less than 28 mN/m for the breaking solution,an anti swelling performance more than 80%,and an increase in the wetting angle between the breaking solution and the coal seam by more than 24° compared to clean water.All performance indicators were superior to industry standards and construction technology requirements.After using variable viscosity and slippery water hydraulic fracturing for 8 horizontal wells in Shenfu Block,the construction success rate was 100%,the construction displacement reached over 22 m3/min,the drag reduction performance reached over 76.8%.The backflow gel breaker is clear and free of sediment and flocculants,achieving a good fracturing and production increase effect.This low damage,viscous and slippery hydraulic fracturing fluid not only protects the reservoir,but also meets the technical requirements of large displacement and large-scale volume fracturing in deep coal seams,and has good application prospects.关键词
