根据研究区实际的储层特点，对水平井开发的可行性进行了分析。结果表明，陕100井区马五1+2储层地质条件适合水平井开发。在对研究区三维精细地质建模的基础上，采用数值模拟对水平井的井网方式、水平段长度、井排距、开发指标等进行了预测。结果表明，最优的井网形式是水平段平行对称布置，采用同时穿越马五12和马五13的阶梯状水平段的水平井，井距和排距均为2 100 m。预测第10年年末，阶梯状水平井的采出程度为48.78 %，比直井的采出程度高16.6 %，研究结果可以指导研究区水平井的高效开发。

According to the practical reservoir characteristics of the study area, the feasibility of horizontal wells development was analyzed, and the result showed that the reservoir characteristics of study area were suit to develop horizontal wells. Based on the establishment of three-dimensional fine geological modeling of study area, using numerical simulation, the well network pattern, length of the horizontal section, well spacing, row spacing and development indicators were predicted. The simulation result showed that the optimal well network was the symmetrical horizontal section, and the horizontal well had echelonment horizontal sections traversing the two layers of Mawu12 and Mawu13, and the well spacing and row spacing were both 2 100 m. The result of development indicators prediction showed that, after 10 years, the recovery percentage was 48.78 %, which was 16.6 % higher than that of vertical wells. The study result can guide the study area to develop efficiently.
