Heavy oil thermal recovery well laying and stopping recovery method

The invention provides a heavy oil thermal recovery well lying and stopping recovery method, which comprises the following steps that a whipstock is put down to a preset windowing position of an old well casing, a windowing tool is put down to the whipstock, and the windowing tool performs side windowing on the old well casing under the inclination guiding action of the whipstock; the windowing tool is pulled out, the sidetrack drilling tool is put down to the windowing position, and the sidetrack drilling tool drills to the well drilling depth according to the track of the well to be drilled so as to form a new well; the sidetrack drilling tool is pulled out, and a well completion pipe string is put into a new well hole; and the annulus between the oil-layer well section and the non-oil-layer well section is sealed and separated, and the well completion operation of the lying and stopping well is completed. The method has the advantages of realization of recovery of production by well stopping during mining,
