| Abstract: | According to the principle that make the biggest deliverability,combining the numerical simulation with the basic geological analysis,the best structure of the pinnate horizontal well is given.The length of the main branch is 1200 to 1500m,the length of branch are 200 to 800m,and it decrease from near area to far area of the horizontal well.The included angle between the main branch with the branch is 45 degree,the distance between the branches is 250 to 300 meters,and the number of branch is 8 to 10. |
