Safety and Fast Horizontal Drilling Technology in Xujiahe Formation of Western Sichuan Basin
Abstract
Xu-2 formation in Xinchang structure of Western Sichuan Basin is a dense fractured reservoir which is buried deeply. Horizontal well drilling technology can effectively develop such gas reservoir. In this paper, first horizontal well of Xinchang Structure Xin10-1H well was taken as an example, the difficulties encountered in its safety and fast drilling were analyzed and corresponding technical measures were proposed. This summary is helpful to promote the technology of safe and fast horizontal drilling in Western Sichuan Basin.
