钻井技术的提高,已将石油工业的注意力集中于水平井的重要性和可行性上,钻水平井的理由是:①增加产量;②更有效地横穿和引流垂直裂缝网络;③减少水锥、气锥;④增加驱油效率。这里,我们考虑的是水平井的产量,该产量可以用最近出版的公式来估算。附图表明了一稳产水平井的物理模型(为比较,图中显示了一中心定位的垂直井)。该物理模型为一封闭的箱式供油面积,其不渗透介面可能是断层变薄或油田中因存在其它井引起的对称情况的结果。 Advances in drilling technology have focused the petroleum industry’s attention on the importance and feasibility of horizontal wells. The reasons for drilling horizontal wells are: (1) increasing production; (2) crossing and draining vertical fracture networks more effectively; (3) reducing water Cone, gas cone; ④ increase the displacement efficiency. Here, we consider horizontal well production, which can be estimated using the recently published formula. The figure shows the physical model of a stable horizontal well (for comparison, a centrally located vertical well is shown). The physical model is a closed tank fueling area whose impermeable interface can be the result of thinning of the fault or symmetry in the field due to the presence of other wells.
