Application of Multi-Well Pad in Unconventional Oil and Gas Development in China

Multi-well pad technology can improve drilling efficiency and save cost,so it has an advantage in developing tight gas,shale gas and unconventional oil and gas,it had been widely used in North America and got huge economic benefits.In order to speed up the popularization of multi-well Pad technology in the development of unconventional oil and gas in our country,this paper analyzed the status quo and application of multi-well pad in other countries by introducing the concept and characteristics of multi-well pad technology.The application of multi-well pad technology in PetroChina and Sinopec were summarized.Comparison and analysis indicated that domestic equipment can not meet the demand of multi-well pad technology now,the production line for drilling is still not perfect,and a set of well-factory operation modes hasn’t taken shape.It was recommended that corresponding engineering technology should be integrated and developed,and multi-well pad department should be established based on the low cost concept to form a set of well-factory technologies suitable for developing unconventional oil and gas resources in China.
