The conventional method, vertical well+ fracturing, has difficulty in mining tight oil reservoir, but the way of “horizontal well+large volume fracturing” can develop effectively and scalely. Based on the knowledge of reservoir geological characteristics, fracturing research, and the conclusion of on-site operation, main techniques are formed. These techniques include oil-bearing tracing & sweet-point prediction, optimal design of horizontal well, volume fracturing technology, fracturing fluid systematic optimization and fracturing factory-style operation. Due to above methods, the effective development technology of tight oil reservoir is established. By the end of 2014, there are 32 horizontal wells in Santanghu basin, 30 of which put out production and build the production capacity of 111,000 tons every year. |
