Horizontal Well Fracturing Technology Research And Application Intuha Oilfield

Tuha Oilfield oil and gas reservoir with low porosity and permeability characteristics, the main types of oil and gas reservoir has edge and bottom water reservoir, volcanic reservoirs, deep heavy oil, tight sandstone gas reservoirs and so on. Horizontal wells technologies are applied to Honglian edge and bottom water reservoir, Santanghu volcanic reservoir, Lukeqin deep heavy oil, Yanmuxi sandstone reservoir and tight sandstone gas reservoirs. Horizontal well production in the range of 0.5 to 40 ton per day, the volcanic reservoir average well production is less than 2 ton per day, heavy oil reservoir for the 5 ton per day, edge and bottom water reservoir above the average yield of up to 9 ton per day. With the development of domestic and international horizontal wells fracturing technology and oil increased demand for crude oil, in recent years, horizontal well fracturing technology in the Tuha Oilfield be a good development, but still at an exploration and experimental stage. This article was departure from the horizontal well fracturing mechanism, through the integrated reservoir evaluation and optimization of fracture parameters, and the latter supporting technology research to improve the success rate of the construction of horizontal wells and fracturing effects. We studied different fracturing fluid and fracturing technology system implementation for different types of reservoir, and achieved good effects.The introduction and research of horizontal wells hydraulic jet fracturing technology open a new phase, for the Tuha Oilfield horizontal wells fracturing.
