裂缝是低渗透油气藏和裂缝性油气藏的主要渗流通道及有效储集空间。油气井有无产能、产能高低及投产措施的有效性在很大程度上取决于射孔孔眼能否直接沟通天然裂缝系统，而孔眼与裂缝面的夹角、射孔弹穿透深度是两个最主要的射孔工艺参数。在扎眼垂直于天然裂缝面或最小水平主应力条件下，孔眼穿透越深，孔眼产量越高。定方位射孔完井技术是提高低渗透油气藏和裂缝性油气藏勘探开发效工的一项新技术措施。射孔完井前，通过定方位优化射孔软件优选射孔参数，然后根据定方位射孔井下仪与地面计算机系统确定射孔枪位置及射孔方位，使之垂直于裂缝面或最小水平主应力实施射孔，将大大提高油气井的产能。
Cracks are the main seepage channel and effective reservoir space for low-permeability reservoirs and fractured reservoirs. The productivity of oil and gas wells, the level of production capacity and the effectiveness of production measures depend largely on whether the perforation can directly communicate with the natural fracture system. The angle between the perforation and the fracture surface and the perforation penetration depth are two The main perforation process parameters. In the grit perpendicular to the natural fracture surface or the minimum horizontal principal stress conditions, the deeper the hole penetration, the higher the yield hole. Directional perforation completion technology is to improve low permeability reservoirs and fractured reservoirs exploration and development efficiency of a new technical measures. Before perforation completion, the perforation software is optimized for the perforation parameters, and then the perforating gun position and perforation orientation are determined according to the directional azimuth downhole instrument and the ground computer system so as to be perpendicular to the fracture surface or the minimum level master Stress perforation, will greatly enhance the productivity of oil and gas wells.
