Abstract

Abstract:

The “Shan-2” in the western exploration area of Jidong Oilfield is mainly a tight gas reservoir with high temperature and poor porosity and permeability, in which the gas can only be produced by fracturing. Conventional guar gum fracturing fluid has poor high-temperature resistance and it is easy to cause secondary damage to the formation. To solve this problem, based on chelation mechanism, a kind of high-temperature resistant carboxymethyl guar gum fracturing fluid was developed. Its rapid thickening, viscoelasticity, high-temperature resistance, shear resistance and formation damage performance were studied in detail. The results showed that, the viscosity of this fracturing fluid could reach 51 mPa·s within 4 minutes. Its temperature resistance could reach 130-180 ℃. The viscosity of the gel breaking fluid was less than 1.5 mPa·s. Therefore, this fracturing fluid could meet the requirements for the target stratum. Finally, for some low-producing and low-efficiency wells in the field, the clean fracturing technology using the carboxymethyl guar gum developed had achieved clean fracturing with low damage. Old cracks were closed and new cracks were opened. The stimulated reservoir volume was increased. The output of low-producing wells had been increased by 3-5 times. This work might provide technical support for continuous and stable production in the western exploration area.

Key words: low production and high efficiency, fracturing fluid, high-temperature resistance, carboxymethyl guar gum, temporary blocking steering
