摘要
The present invention relates to an oil producing method through horizontal drilling destruction of a shale layer coordinated in a reservoir layer comprising: (a) step of drilling a production well in oil sand layer; (b) step of drilling an injection well in the oil sand layer; (c) step of destroying a part of the shale layer by inserting a drilling hole into a side of the shale layer coordinated in the oil sand layer, penetrating the drilling hole along a length direction of the shale layer, and removing a part of the drilling hole; (d) step of discharging stem through a discharge hole formed in the injection well; (e) step of enabling the discharged steam to be penetrated in the oil sand layer and the oil sand layer which is formed on an upper part of the shale layer through a drilled part of the shale layer formed by destroying the shale layer in the (c) step, producing liquid oil from oil sand; and enabling the liquid oil to be applied to the production well; and (f) step of discharging the liquid oil applied to the production well to the outside. The present invention is provided to enable the steam, which is much more than before the destruction of the shale layer, to be penetrated to the oil sand layer; and apply the liquid oil to the production well, thereby improving oil production.;COPYRIGHT KIPO 2016
