【摘要】：在油藏地質(zhì)研究方面,能夠較為準(zhǔn)確地進(jìn)行油、水層識(shí)別一直以來(lái)都是一個(gè)非常值得關(guān)注的問(wèn)題。彭灘-新安邊地區(qū)長(zhǎng)6組屬于低孔特低滲儲(chǔ)層,當(dāng)前開(kāi)采產(chǎn)水量高、采出程度低,測(cè)井解釋符合率偏低,開(kāi)展研究區(qū)測(cè)井二次精細(xì)解釋研究工作,重新確定油水層解釋標(biāo)準(zhǔn),確定有效厚度,對(duì)指導(dǎo)油田開(kāi)發(fā)生產(chǎn)具有重要意義。本文以彭灘-新安邊地區(qū)長(zhǎng)61小層為例,首先進(jìn)行測(cè)井系列優(yōu)化,通過(guò)圖示法和相關(guān)對(duì)比法進(jìn)行巖心深度歸位。由測(cè)井?dāng)?shù)據(jù)和試油資料分析發(fā)現(xiàn)研究區(qū)存在低阻油層,并研究低阻成因,故而將工區(qū)劃分為南北兩區(qū)。然后研究“四性”關(guān)系,建立兩個(gè)區(qū)塊儲(chǔ)層孔、滲、飽和泥質(zhì)含量參數(shù)計(jì)算模型。最后采用交會(huì)圖技術(shù)分別確定南北兩區(qū)油層電性解釋標(biāo)準(zhǔn),進(jìn)而建立了一套適合兩分區(qū)的測(cè)井解釋模型。分析油井試油結(jié)論與二次解釋結(jié)果表明,建立的該套測(cè)井二次解釋模型能夠較準(zhǔn)確地識(shí)別油、水層,確定有效厚度。
[Abstract]:In the aspect of reservoir geological research, can more accurately identify oil and water has always been a very important problem. Peng Tan - Xin'an border region 6 low Kong Te group belongs to low permeability reservoir, the exploitation of high water yield, low recovery degree, the coincidence rate of logging interpretation is low, carry out research two log fine interpretation of research work, to determine the oil layer interpretation standard, determine the effective thickness, is of great significance to guide the development and production of oil. In this paper, Peng Tan - Xin'an border region 61 layer as an example, the first log series optimization, core depth homing by graphic method and the correlation method by logging. The data and testing data analysis shows that there are low resistivity reservoir in the study area, and study the genesis of low resistivity, so the area is divided into North and south two areas. Then study the correlation of four, two building blocks of reservoir pore permeability, saturation, clay content The parameter calculation model. Finally, the crossplot technique identified two areas of the north and South oil electric interpretation standard and interpretation model is established for a two partition analysis of oil well logging. Test results and the two interpretation results show that the establishment of the two set of logging interpretation model can accurately identify the oil, water, determination effective thickness.
