行列井网火驱气液分离采油井网结构
摘要：
本实用新型提出了一种行列井网火驱气液分离采油井网结构，其包括沿水平方向依次设置的第一注气井排、第一采油井排、第二采油井排、采气井排、第三采油井排、第四采油井排和第二注气井排；第一注气井排和第二注气井排均包括至少一口注气直井，第一采油井排、第二采油井排、第三采油井排和第四采油井排均包括至少一口采油直井；采气井排包括间隔设置的采油直井和采气直井。本实用新型实现气液分采，提高了单井产量，并提高了注入能力，实现燃烧前缘稳定向前推进，进一步提高火驱采收率。
摘要（英）：

The utility model provides a line well pattern fireflood gas -liquid separation oil recovery well pattern structure, it includes first gas injection well array, first oil recovery well array, second oil recovery well array, gas production well array, third oil recovery well array, fourth oil recovery well array and the second gas injection well array of following the horizontal direction and setting gradually, first gas injection well array and second gas injection well array all include at least pure gas injection straight well, and first oil recovery well array, second oil recovery well array, third oil recovery well array and fourth oil recovery well array are all including the straight well that recovers the oil at least flatly, the gas production well array includes oil recovery straight well and gas production straight well that the interval set up. The utility model discloses realize the gas -liquid branch and adopt, improved single well yield to improve injection ability, realized the combustion front and stabilize forward propulsion, further improved the fireflood recovery ratio.
