Jiaoye No.50 platform is located in Xinli Village, Tiantai Township, Fuling District, with eight horizontal wells. It is the largest platform with the densest number of wells in Fuling shale gas field at present, and adopts the "well factory" mode of batch drilling with two rigs. The design well of Jiaoye 50-8HF is 4550m deep, and Longmaxi Formation and Wufeng Formation are mainly explored, with the horizontal section of1.256m.. It is estimated that all 8 wells will be drilled in June 5438+1October.
Since 20 13 was put into commercial development, exploration and development units have scientifically organized construction and promoted technological innovation in view of the complex stratum and difficult drilling construction in Jiaoshiba area, and formed a series of technologies with independent intellectual property rights, such as clean water drilling technology, low-density leak-proof cementing technology and "well factory" drilling mode. The operation mode is becoming more and more mature, and the drilling speed is obviously improved. In 20 14, the average completion period of this gas field is 75 days, which is 20 days shorter than that in 20 13.
In 20 15, Fuling Shale Gas Company plans to drill 86 wells, complete drilling 128 wells, and fully complete the production and construction tasks of 5 billion cubic meters and 3.5 billion cubic meters in the first phase of the gas field. The smooth drilling of Jiaoye 50-8HF well marks a solid step towards localization, scale and serialization of drilling construction in Fuling shale gas field, which will greatly accelerate the pace of commercial development of Fuling shale gas.
