On September 16, 2012, our company implemented a horizontal well coiled tubing fracturing monitoring project in Xiao14-Ping28 well in Xiaolongwan Oilfield, Liaohe River. The horizontal section of this well is 68 meters in length and 8 sections of perforated sections. Through monitoring, all 8 sections are fractured. Among them, 1 fractured section has poor fracturing effect, and 2 fractured sections have good fracturing effect. The fracturing effect of 5 fractured well sections was moderate. Repeated fracturing measures were carried out after the completion of the test on the well section with poor fracturing effect.
