Gas reservoir technology is an effective development mean of low permeability gas reservoir. The low-yielding low-permeability gas field properties directly determine its difficult to achieve the requirements of economic development,only through a single well hydraulic fracturing to enhance production capacity in order to show the value of industrial development.In this paper, a study of Xiao helong gasfield in the shallow gas reservoir, due to the depth of buried layer of natural oil and gas production capacity is low, gas reservoir fracturing is necessary to the production means. With the fine study of gas reservoir begin, combined with the exploration wells, the evaluation of oil well test data and static and dynamic fracture tests and test results, combined with the development of well pattern characteristics and the characteristics of a compartment under Inoue, fitting technical guidance to stress the design of the fracturing raphe high optimization, to optimize the design parameters and scale of fracturing. Of sandstone gas reservoir in the shallow reservoir of low temperature (25-45℃), breaking study of low-temperature plastic fracturing fluid system and clean fracturing fluid system and reduces formation damage. Operation of the production process to study the formation of the perforation, fracturing and production technology in conjunction to make. Fast-back after fracturing a mandatory closure of the study, to reduce the proppant in the wellbore near the deposition zone, thus improving the support section of the cracks. To obtain good results.Improved for the production of gas formation after fracturing sand back to the preventive measures -ceramsite sand resin technology to meet the needs of the different temperature and curing time requirements.After research the topic, forming a fracturing matching technology of Xiao helong shallow gas reservoir, Jilin Oilfield on the development of shallow natural gas to provide a guide.
