下面是一个示例的解决方法，使用Bitbucket API来对已还原合并的拉取请求进行工作，并为同一分支创建新的拉取请求。

import requests

# 定义Bitbucket的URL和认证信息
base_url = "https://api.bitbucket.org/2.0"
username = "your_username"
password = "your_password"
auth = (username, password)

# 获取已还原合并的拉取请求
def get_restored_pull_requests(repo_owner, repo_slug):
    url = f"{base_url}/repositories/{repo_owner}/{repo_slug}/pullrequests"
    response = requests.get(url, auth=auth)
    data = response.json()
    
    # 遍历拉取请求，找到已还原合并的请求
    restored_pull_requests = []
    for pull_request in data["values"]:
        if pull_request["state"] == "MERGED" and pull_request["closed"] and pull_request["source"]["commit"]["hash"] != pull_request["destination"]["commit"]["hash"]:
            restored_pull_requests.append(pull_request)
    
    return restored_pull_requests

# 创建新的拉取请求
def create_new_pull_request(repo_owner, repo_slug, source_branch, destination_branch):
    url = f"{base_url}/repositories/{repo_owner}/{repo_slug}/pullrequests"
    data = {
        "title": "New Pull Request",
        "source": {
            "branch": {
                "name": source_branch
            }
        },
        "destination": {
            "branch": {
                "name": destination_branch
            }
        }
    }
    response = requests.post(url, json=data, auth=auth)
    new_pull_request = response.json()
    
    return new_pull_request

# 示例用法
repo_owner = "your_repo_owner"
repo_slug = "your_repo_slug"
source_branch = "your_source_branch"
destination_branch = "your_destination_branch"

restored_pull_requests = get_restored_pull_requests(repo_owner, repo_slug)
for pull_request in restored_pull_requests:
    new_pull_request = create_new_pull_request(repo_owner, repo_slug, pull_request["source"]["branch"]["name"], destination_branch)
    print(f"Created new pull request: {new_pull_request['links']['html']['href']}")

上述代码使用Python的requests库发送HTTP请求，并使用Bitbucket API进行操作。首先，get_restored_pull_requests函数获取已还原合并的拉取请求。然后，create_new_pull_request函数创建新的拉取请求。最后，示例用法中遍历已还原合并的拉取请求，并为每个请求创建新的拉取请求，并输出新拉取请求的URL。

请注意，你需要将代码中的your_username，your_password，your_repo_owner，your_repo_slug，your_source_branch和your_destination_branch替换为实际的值。此外，为了安全起见，建议将认证信息存储在安全的方式中，而不是直接在代码中硬编码。
