The Honghe Oilfield Fracturing Technology Research And Application

Hydraulic jet fracturing technology is different from the conventional hydraulic fracturing.This Technology synthesizes hydraulic perforation,hydraulic fracturing and drown out in casing tubing annulus.It can make fracture in the specified location,don’t use the unique feature of water jet to stimulate reservoirs,is applicable to low permeable straight well and horizontal well.Generally,reservoirs in Hong He oilfield are buride deep,the physical property of reservoirs is poor and formationtemperature is high.Especially the water flood development,the condition of oil well and water well become more complex,owing to constant adjustment and implementation of the development program and reasons of the geology,engineering,management and others.In such reservoir,the conventional hydraulic fracturing already cannot satisfy the need of fine development.Therefore,research on fracturing already cannot satisfy the need of fine development.Therefore,research on fracturing technique used in the deep,low permeability and complex well conditions in this article,hydraulic jet fracturing technology has important significance on development of the mid-late field.In this paper,based onnumerical simulation,we studied the hydrraulijet fracturing mechanisms,optimized fracturing fluid and proppant.At the same time,we improved fracturing fracturing parameter and studied important parameter based on grey relational analysis for factor weights. Fracturing technologies,suitable for complex well condition reservoirs in deep zone and low permeability condition,was created and proved successful in practice. Such fracturing technologies procide technical support for increasing production of complex well conditions in Hong He oil-field in the next step.
