Abstract
The cluster well group in Zhongjiang structure is faced with a series of difficulties, e.g. stressful interwell anti-collision, difficult trajectory control and long drilling cycle. To deal with these difficulties, the "well factory" trajectory control technology for tight sandstone gas reservoirs was developed referring to domestic and foreign successful experience of "well factory" trajectory control technologies for shale gas reservoirs. This technology takes notch-target point arrangement optimization, "multi-increase" borehole trajectory design, deviation control and fast drilling of vertical hole section and interwell anti-collision as the core. This technology was, for the first time applied to the development of 6 wells on JS33-19HF pad. It is indicated that based on the optimized trajectory design and the trajectory control technology, wellbore quality is guaranteed and rate of penetration (ROP) is increased. Average ROP of the well group is 54.1% higher than the designed value and the drilling cycle is actually shortened by 102.47 d. The successful application of this "well factory" trajectory control technology for tight sandstone gas reservoirs plays an important guiding role in the efficient development of tight sandstone gas reservoirs.关键词
