Foreword

The company has a number of mature application of technology, tools and services over the past 20 years more than 12,000 well, the efficiency of more than 98%, 0 tools! Creating a series of unmanaged layer by layer hierarchical fracturing precedent; created a horizontal well a string drag 14 fracturing, fracturing the maximum pressure 117MPa and a number of influential construction records.
