摘要
随着勘探地质目标的日益复杂和钻井自动化程度的不断提高,随钻电阻率测井技术已成为开发复杂油藏的关键技术,同时也对随钻电阻率测井仪器测量精度提出更高的要求。依据随钻电阻率测井仪器响应模拟得到的结果建立系统、准确的随钻电阻率测量资料解释理论,对开发高性价比的随钻电阻率测井仪器具有重大的意义。文章介绍了目前四种主要的随钻电阻率测井仪响应模拟算法:BCGS-FFT法、时域有限差分法、传输线矩阵法和有限元法,综合分析了它们各自的特点以及在该领域的应用情况,并展望了随钻电阻率测井仪器响应模拟研究的发展方向。
Nowadays, the worldwide petroleum industry has significantly progressed, branch holes and horizontal wells are used to exploit oil reservoir which is smaller, thinner and worse. Resistivity LWD has become the key technique of complex oil reservoir development. With the widely use of resistivity LWD techniques, high-accuracy measurements are needed for resistivity LWD tools. So, the systemic and accurate resistivity logging interpretation method while drilling should be built based on the simulation result. It is important for development of highly efficient and cost-effective resistivity LWD tool. Four kinds of simulation arithmetic are introduced in this paper: BCGS-FFT, FDTD, TLM and FEM. In this paper, the characters of these methods and the future of resistivity LWD measurements simulation are both discussed.
