Efficient development technologies and application effects of tight sandstone gas in Ordos Basin
after 20 years of development practices and technical innovations
it has become China’s largest natural gas production base. The gas reservoir development process is divided into 3 stages of evaluation
production establishment
stable production and recovery enhancement. During the evaluation stage
a continental tight gas depositional model and development theory were established
as well as key technologies such as low-cost development strategies
preferential selection of enrichment zones
and evaluation of development indicators
which promoted effective reserve utilization. In the production establishment stage
the increasing geological understandings and the demand for improving single-well output led to the development of well type and well pattern optimization and reservoir fracturing stimulation techniques
supporting a rapid increase in production. In the stable production and recovery enhancement stage
precise reservoir characterization continued to be improved
forming a series of recovery enhancement technologies with a focus on improving reserve utilization. Supported by a large-platform
factory-like operation mode
these technologies can reduce costs and increase efficiency
thus ensuring the benifit and effectiveness of gas field development. The recommendations include tackling problems in key technologies
such as continuously implementing fine potental tapping
three-dimensional development of Upper and Lower Paleozoic tight zones
as well as efficient utilization in water-rich areas
and improving comprehensive treatment measures for low-production and inefficient wells. These efforts aim to continuously enhance development levels and benefits.
