Method for uniformly injecting multi-component thermal fluid in horizontal well

The invention provides a method for uniformly injecting a multi-component thermal fluid in a horizontal well. The method comprises the following steps: (1) segmenting horizontal segments in the horizontal well; (2) initially setting the size of each discharge orifice on a tubular column in each segment of the horizontal well and the number of discharge orifices at a tail end; (3) detecting the temperature, pressure and dryness of the multi-component thermal fluid; (4) obtaining the on-way temperature, pressure, dryness and heat loss of each shaft segment of the horizontal well by iterative calculation; (5) obtaining the actual number of the discharge orifices on the tubular column in each segment of the horizontal well and the size of each discharge orifice by iterative calculation; and (6) drilling the tubular column based on the calculation result, putting the tubular column subject to drilling down into the well, and injecting the multi-component thermal fluid in the tubular column. The invention has the advantages of wide oil pool application range, relatively simple technology and low cost, and ensures that the oil pool at the horizontal well segment can be subject to uniform steam injection without changing the traditional well orifices and steam injection pipes. Besides, by using the invention, the producing degree of the oil reservoir is improved and the optimal exploitation effect can be ensured by injecting the multi-component thermal fluid in the horizontal well of the exploited oil pool.
