【摘要】：隨著油氣資源勘探及開發(fā)難度加大,由陸相、高孔滲、均質、淺層逐漸過渡到海相、低孔滲、非常規(guī)、深層油氣資源,其"復雜非均質"特性使得對地層流體特別是地層水及其導電特性評價尤為關鍵.利用試井分析數(shù)據(jù)可獲得精確的地層水礦化度信息,但試井數(shù)據(jù)有限,不能獲得每個儲層的地層水礦化度及電阻率信息,且試井分析成本高、時間長,而測井曲線通過一定的理論計算公式能夠提供地層水電阻率信息.在地層水特性分析的基礎上,根據(jù)地層水電阻率評價技術研究進展,本文將其分為三種主要計算類型:水樣分析評價方法、常規(guī)測井評價方法和成像及核磁測井評價方法,總結和討論不同測井評價地層水電阻率的方法原理,并闡述其應用過程中的優(yōu)勢和不足,同時對地層水電阻率測井儀器國內外進展現(xiàn)狀進行闡述.
[Abstract]:As the exploration and development of oil and gas resources become more difficult, from continental facies, high porosity and permeability, homogeneity, shallow layer to marine facies, low porosity and permeability, unconventional, deep oil and gas resources, Because of its complex heterogeneity, the evaluation of formation fluid, especially formation water, and its conductivity is very important. Accurate formation water salinity information can be obtained by using well test analysis data, but the well test data is limited, and the formation water salinity and resistivity information of each reservoir can not be obtained, and the well test analysis cost is high and the time is long. The logging curve can provide formation water resistivity information through a certain theoretical formula. Based on the analysis of formation water characteristics, according to the research progress of formation water resistivity evaluation technology, this paper divides it into three main calculation types: water sample analysis and evaluation method, conventional logging evaluation method, imaging and nuclear magnetic field logging evaluation method. This paper summarizes and discusses the methods and principles of different logging methods for evaluating formation water resistivity, and expounds the advantages and disadvantages in its application. At the same time, the present situation of formation water resistivity logging tools at home and abroad is expounded.
