摘要:
MX井是明格布拉克构造上的一口“五高”深井，为保证试油测试安全实施，依据该井地质工程特征，优选试油方案，采用射孔测试联作技术、“两关一开”工作制度和“三阀一封”管柱结构。试油测试过程中，按设计要求控制油压和套压，防止油管和封隔器窜漏；起管柱前，压稳井，保证井控安全；按照防硫气体要求做好设备选择、安装和调试的工作，并依据探测H2S含量做出合理的相应措施以保证含硫井试油的安全；现场需要判断盐结晶，一旦确定发生盐结晶，立即循环压井以防盐堵。MX井7个层段试油结果：最高地层压力11157 MPa，最高地层温度16341℃，最大日产油量2267 m3，最高日气产量1843×104m3，最高日产水量3937 m3，最高H2S含量44%，盐水Cl-最高为2150×104mg/L，获得油气水样品和相关压力资料，实现高温高压安全试油测试作业，达到了试油目的。该工艺在高含H2S和高含盐的“五高”深井中实现技术突破，为“五高”深井试油测试提供了技术借鉴。
Abstract:
Well MX is a key exploration well of the characteristics of “five highs and deep”, targeted research of oil testing technology is required to ensure the safe and smooth operation of oil testing. According to the geological engineering characteristics of the well, the oil testing scheme of "the operation mode perforation and well test joint, the producing and closing system of two time close and one time open and the string structure of “three valve and one packer”is optimized. In the process of oil test, tubing pressure and casing pressure are controlled according to the design requirements to prevent the leakage of tubing and packer, the well is killed and stabilized to ensure the safety of well control before downhole string is lifted; selection, installation and commission of the equipment are done according to the requirements of prevention sulfur gas, reasonable corresponding measures are made to ensure the safety of sulphur well test based on the detection of H2S content; the salt crystallization is determined on oilfield, and once the salt crystallization is confirmed, the well is killed immediately to prevent salt plugging. In 7 intervals of MX Well，the maximum formation pressure is 11157 MPa, the maximum formation temperature is 16341℃, the maximum daily oil production is 2267 m3, the maximum daily gas production is 1843×104m3, the maximum daily water production is 3937 m3, the maximum H2S content is 44%, and the maximum salt water Cl is 2150×104mg/L; the oil, gas and water samples and related pressure data are obtained to realize the safety of high temperature and high pressure oil testing operation and achieve its purpose，and technical breakthroughs in high H2S and salt content are realized. The implementation process in this paper can shed light on the oil test for "fivehigh" deepwell.
