1. The outstanding feature of low price horizontal well is that the length of the wellbore passing through the oil layer is long, which greatly increases the contact surface area between the well and the oil layer, so that the single well production of the oil well is high, the production speed of the oil well is fast, and the production time is reduced.
2. Low price horizontal well In rock formations with natural fractures, natural fractures can be connected to each other. Since the permeability of natural fractures is much greater than that of the rock matrix, the pressure loss of oil and gas flowing into the wellbore is reduced, and the formation resistance is very small. Therefore, a large number of oil reservoirs that have no mining value with vertical wells or ordinary directional wells have industrial mining value.

3. If the production layer is driven by water, when the viscosity of crude oil is much higher than that of water, the vertical well may encounter the problem of water cone. Low price horizontal well can build deflection in the middle and upper part of the oil layer, and then drill a certain length in the production layer. It can not only reduce the possibility of water cone and prolong the water-free oil production period, but also the pressure drop per unit length of the oil production section is lower than that of the vertical well production section, and other effects are also improved. At the same time, Low price horizontal well can reduce the harmful effects of gas cones and increase the production of oil wells.
4. Low price horizontal well can run through several thin oil layers continuously, so that oil layers without industrial exploitation value can also be produced, and the recovery rate of crude oil can be improved.
