RESEARCH OF ARTIFICAL COMPARTMENT TECHNIQUE FOR THICK RESERVOIR

This technique can be described as follows:combine the fracturing technology and the chemical water shutoff technology, form artificial compartment in thick reservoir, change the water flood condition, and thus produce more oil from it. While conducting, the requirements for the pipe string technology are strict:the sticking distance must be short, the fracture must be located; the pipe string should not only meet the requirements of fracturing technology, but also of waiting-on water shutoff technology.
