【摘要】：為確定青海油頁巖勘查過程中油頁巖的最佳采樣長度(以下簡稱"樣長"),在系統(tǒng)開展野外地質(zhì)工作和樣品采集化驗(yàn)基礎(chǔ)上,分析認(rèn)識青海油頁巖地質(zhì)特征,分別用類比法、統(tǒng)計(jì)學(xué)方法和試驗(yàn)法,得出技術(shù)和經(jīng)濟(jì)方面均合理的最大樣長。結(jié)果顯示:(1)由于油頁巖與同為固體可燃有機(jī)巖煤的宏觀識別程度、有用組分的變化過程和分布均勻程度均存在差異,所以不能完全參考煤的采樣規(guī)格;(2)通過統(tǒng)計(jì)分析Y-1Y和Y-6Y井油頁巖含油率正態(tài)分布類型為對數(shù)分布,與許多鉬、錫、鎢以及貴金屬礦床的典型樣品數(shù)據(jù)正態(tài)分布形態(tài)類似,可類比其樣長規(guī)格,確定油頁巖樣長為1.5~2.0m;(3)對Y-1Y井中選定的加密采樣層段含油率數(shù)據(jù)應(yīng)用減稀法得出最大樣長為1.5m或1.6m。
[Abstract]:In order to determine the optimum sampling length of oil shale in Qinghai oil shale exploration process (hereinafter referred to as "sample length"), on the basis of systematic field geological work and sample collection test, the geological characteristics of Qinghai oil shale are analyzed and recognized, and the analogy method is used respectively.The maximum sample length of both technical and economic aspects is obtained by statistical and experimental methods.The results show that due to the macroscopic recognition degree of oil shale and the same solid combustible organic rock coal, the variation process and distribution uniformity of useful components are different.Therefore, the normal distribution type of oil content of oil shale in Y-1Y and Y-6Y wells is logarithmic distribution, which is similar to the normal distribution form of typical sample data of many molybdenum, tin, tungsten and precious metal deposits.The oil shale sample length is determined to be 1.5 ~ 2. 0 m ~ 3) by using thinning reduction method, the maximum sample length is 1.5 m or 1.6 m for the selected infill sampling interval oil content data in Y-1Y well.
