Abstract


Fracturing is the effective measures in the low permeability dense reservoir and it is widely used the site. Sulige gas field is the low permeability and output. It has no value without the stimulation measures. The Sulige gas field is the rock reservoir controlled by the transversal expansion and permeability variance of the rock. It has the special properties such as high temperature, very dense, strongly heterogeneity. It does harm for the formation. All these problems put forward new requires to the technical and facility of the hydraulic fracturing. Based on the character of the Sulige gas field with low porosity, low permeability, low pressure, do a lot of experiment, such as fluid optimize and proppant screening, summarizing a stimulation way fit for the Sulige gas field.Based on the gas field character and geological character, analyzing the requirement and difficulties of the fracturing, technology strategies are put forwards. Analyzing the formation sensitive evaluation, optimizing the fluid additive, developing the fluid system with high clay inflation inhibition, low friction, temperature-resistive inflation. From the optimizing design and treatments parameters, bring forward the model of appropriate scale fracturing.The successful treatments on the site show that it is fit for the Sulige gas field stimulation. It solved the puzzle of the Sulige gas field on some degree, and generalizes the effective matching technique of the Sulige gas field hydraulic fracturing.
