摘要:
一次循环法压井方法(即工程师法、等待加重法)是常规压井方法,但在应用中常因套压控制不当等原因,导致压井失败。以元坝272-1H井和清溪1井压井作业为例,分析认为对井内压力平衡问题认识不到位、套压控制不当、压井排量不合理等是导致一次循环法压井失败的主要原因,并以井内压力平衡控制为基础,给出了环空仍然有钻井液和环空喷空2种情况下的一次循环法压井参数计算方法与压井工艺,该压井工艺在HF203井井喷压井中进行了成功应用。研究与应用表明,基于井内压力平衡的一次循环法压井工艺,对于能够正常循环的溢流井喷,具有非常好的可操作性,能够实现快速压井成功。
Abstract:
The engineer’s method(waiting for weighting method) is a conventional well killing method.Failed attempts to kill the well in a blowout situation is frequently observed when there has been improper control of casing pressure in the field.Taking the well killing operations in Well Yuanba 272-1H and Well Qingxi 1 as examples,the analysis demonstrates that insufficient understanding on pressure balance inside the hole,improper control of casing pressure,and unreasonable killing flow rate are the main reasons in failed killing when using the engineer’s method.By taking the control of pressure balance inside the hole as a reference,this paper presents two cases which utilize a killing parameters calculation method and the killing process of the engineer’s method.In the two cases,the annulus is partially filled and fully emptied with drilling fluid,respectively. Such killing process has been successfully applied in controlling the blowout of Well HF203 successfully.The research and field applications suggest that inside hole pressure balance-based engineer’s method can bring about the rapid control of overflow and a blowout under normal fluid circulation.
